Acurácia da tomografia computadorizada de feixe cônico e a influência do tamanho do voxel na identificação de lesão de furca em molares superiores
(Universidade Federal de Goiás, 2018-08-30) Oliveira, Paula Renata Damaceno; Roriz , Virgílio Moreira; http://lattes.cnpq.br/4602848040014140; Silva, Maria Alves Garcia Santos; http://lattes.cnpq.br/8760691456576488; Silva, Maria Alves Garcia Santos; Souza, João Antônio Chaves de; Picoli, Mayara Viandelli Mundim; Roriz, Virgílio Moreira
Furcation lesion, bone loss in the region of the multiradicular teeth, is a big challenge in the treatment of patients with periodontitis. The aim of this study was to compare the accuracy of CBCT and the influence of voxel size on the identification of furca lesion in upper molars. This was a cross-sectional observational study, which the sample consisted of 120 sites with chronic periodontitis from 12 patients with periodontits, in whom scrapie access surgery and CBCT were indicated for the treatment of periodontal disease. The same periodontist made the clinic diagnostic of presence and absence of furcation lesion, horizontal bone loss and vertical bone loss. The CBCT images were obteined with I-CAT Cone Beam 3D Imaging System - Next Generation (Imaging Sciences International, Hatfiels, PA, USA), with isometric voxel of 0.125 mm 3; FOV of 8 x 8 cm, 120 kV and 5 mA current, and acquisition time of 26.9 s. Subsequently, the images were reformatted in other sizes of voxel (0.200 mm 3 and 0.250 mm 3), and evaluated by three experienced radiologists, previously calibrated. Transurgical, clinical and radiographic measurements were performed in a similar way and at the same sites. Cohen's Kappa, Intraclass Coefficient, McNemar and Wilcoxon tests were performed.The level of significance was set at 5% (p <0.05). In the evaluation of vertical bone loss, the intra-examiner agreement (ICC between 0.805 and 0.916) and inter-examiner (ICC between 0.754 and 0.965) were excellent for vertical bone loss. Regarding the presence or absence of the defect, it was good (k: 0.615) to very good (k: 1,000) in intra-examiner agreement, and was good (kappa between 0.619 and 0.773) for inter-examiner agreement. For horizontal bone loss, it was moderate (k: 0.424) to very good (k: 1,000) in intra-examiner agreement, and moderate (kappa between 0.463 and 0.590) for inter-examiner agreement. The 0.125 mm³ voxel presented the best agreement for all evaluations. Compared with the different sizes of voxel with the gold standard, statistically significant difference (p <0.05) was observed at the distal site, and it was easier for the examiners to diagnose furcation lesions at this site. The CBCT for the diagnosis of incipient furcation defects, showed an accuracy of 75%, demonstrating a greater specificity of the imaging tests in detriment of sensitivity. The clinical evaluation showed a greater sensitivity, 80%, in the detection of furcation defects, showing the importance of a good evaluation for the diagnosis and treatment of patients in this condition. The tomographic measurement at the distal site showed greater proximity with surgical measurement. When tomographic image is required for furcation evaluation, the smaller voxel should be preferred because it presents better results.
Acurácia de dois tomógrafos na detecção de fraturas radiculares verticais em dentes com retentores metálicos intracanais
(Universidade Federal de Goiás, 2017-03-10) Siqueira, Claudeir Felipe de Oliveira; Silva, Brunno Santos de Freitas; http://lattes.cnpq.br/1575170017237525; Silva, Fernanda Paula Yamamoto; http://lattes.cnpq.br/0511229119340734; Silva, Fernanda Paula Yamamoto; Estrela, Carlos; Leite, André Ferreira
Vertical root fracture (VRF) is a dental lesion with worse prognosis in dentistry, the diagnosis is made from clinical evaluation, and image exams, clinically the symptoms are signaled and not pathognomonic and even with the introduction of cone beam computed tomography, the metallic artifacts resulting from the images obtained still make it difficult to detect VRF. The aim of this study was to evaluate the accumulation of Eagle 3D and i-Cat tomography in the detection of VRF in endodontically treated single-root teeth with post metallic intracanal. This study was approved by the Research Ethics Committee of UFG under the number 477.315. 30 single-root teeth were endodontically treated and prepared with metal pins. The sample was divided randomly in Control Group (CTL) and Fractured Group (FRT). The fractures were made only in FRT Group by the Universal Test machine, with load cell 500N and speed of 1mm/ min. The teeth were placed in dry jaw and placed in a vessel with distilled water to be purchased as TCFC images by Eagle 3D tomographs (protocol 1: FOV 5X5 cm and voxel: 0.1 mm - protocol 2: FOV 6X8 cm and voxel: 0.16 mm) and i-CAT (protocol 3: FOV 8 × 8 cm and voxel: 0.125 mm - protocol 4: FOV 8 × 8 cm and voxel: 0.2 mm). Two experienced evaluators classified as composite images by absence of fracture or by subjective revisions of an interference of the formation of non-diagnostic artefacts and reconstruction type and efficient in the detection of VRF. The inter-examiner agreement was verified by kappa test. Measurements of sensitivity, specificity and accuracy were adopted for each device. The area under the ROC curve was also calculated and compared using the ANOVA. The results indicated that protocols 1 and 3 were more accurate (AUC protocol 1: 0.784 - p <0.05 and AUC protocol 2: 0.729 - p <0.05). According to the subjective evaluation of the examiners, in protocols 1 and 4 of greater interference of the formation of artifacts without diagnosis of VRF and a parasagittal reconstruction was the most efficient for a detection of the fracture line. It is concluded that protocols 1 and 3 highlight a better performance in the detection of VRF and that the size of voxel is a factor that directly influences the accuracy.
Acurácia de três tomógrafos e um programa de redução de artefatos (e-Vol DX) na detecção de fraturas radiculares verticais
(Universidade Federal de Goiás, 2019-12-10) Caetano, Aline de Paula Ferreira; Sousa, Thiago Oliveira; http://lattes.cnpq.br/0132482031214690; Silva , Maria Alves Garcia Santos; http://lattes.cnpq.br/8760691456576488; Silva, Maria Alves Garcia Santos; Arruda, Karine Evangelista Martins; Rabelo, Luiz Eduardo Gregoris; Silva, Fernanda Paula Yamamoto; Porto, Olavo Cesar Lyra
Objective: To test the accuracy of three Cone Beam Computed Tomography (CBCT) devices and a CBCT imaging software with artifact reduction filters (e-Vol DX) in the diagnosis of vertical root fractures (VRF) in teeth without filling material, teeth with filling material and teeth with intracanal metallic post. Methods: 45 extracted human monoradicular premolars were divided into three groups according to the clinical condition concerning the root canal filling: 15 without filling material (WF), 15 with gutta-percha (GP) and 15 with intracanal metallic post (MP). The teeth were scanned on three different CT scanners (Kodak 9000® 3D, Orthopantomograph® 300 OP300 and PreXion 3D®) using the maximum resolution available in each device. Every tooth in the sample was artificially fractured and re-scanned under the same pattern. Two examiners evaluated the images using the InVivo (Anatomage) software and the e-Vol DX (CDT) software. The images were evaluated regarding the presence or absence of fracture using a five-point scale. In order to assess the method error, 30% of the images were re-evaluated after a minimum intermission of 15 days from the first evaluation. The intra and inter examiner concordances were obtained using the Kappa coefficient. Diagnostic tests determined the sensitivity, specificity and accuracy of the images of each CT scanner using both software. Results: The PreXion 3D® CT scanner was the most accurate in all evaluated groups (InVivo: 0.96; e-Vol DX: 0.92). In the WF and MP groups, the PreXion 3D® and OP300 CT scanners demonstrated equivalent accuracy when evaluated in InVivo software (WF: p = 0.2090; MP: p = 0.0950). There was no statistical difference between images analyzed with e-Vol DX (p = 0.8880). Conclusions: The PreXion 3D® CT scanner presents the best accuracy compared to the other CT scanners in both software. For the WF group, there is no difference between the PreXion 3D® and OP300 CT scanners regardless of the software used to evaluate the images. The Kodak 9000® 3D CT scanner presents lower accuracy in the tested groups. The e-Vol DX software does not contribute to a greater accuracy in the diagnosis of VRF.

(Universidade Federal de Goiás, 2011-12-16) Cavalcante, Julianna Amaral; Costa, Luciane Ribeiro de Rezende Sucasas da; http://lattes.cnpq.br/9906371509661305; França, Cristiana Marinho de Jesus; Heck, Elisa Tavares Sanabio
Este estudo objetivou realizar a adaptação transcultural da versão em inglês da “PainCatastrophizingScale – Parents” para a língua portuguesa do Brasil e avaliar suas propriedades psicométricas em um grupo de crianças com e sem cárie dentária. Estudo observacional transversal realizado com uma amostra de conveniência de 240 pacientes. As propriedades psicométricas da Escala de Catastrofização da Dor – Pais (ECD-P) foram examinadas avaliando a fidedignidade e a validade deste instrumento. A análise fatorial confirmatória evidenciou que o modelo de três fatores, para a ECD-P, apresentou-se marginal, com os seguintes indicadores: qui-quadrado 241,43/62 graus de liberdade (P < 0,001), CMIN/DF 3,89, RMSEA 0,11, NNFI 0,76 e CFI 0,80. O coeficiente de correlação interna (alfa de Cronbach) para os 13 itens da ECD-P foi de 0,83. A análise da correlação item-total indicou que não haveria melhora nesse valor caso se retirasse algum item. O alfa de Cronbach foi de 0,70 (ruminação), 0,62 (ampliação) e 0,76 (desesperança).Houve correlação significante entre os escores obtidos na ECD-P e na DDQ (P < 0,001); o coeficiente de correlação de Spearman foi 0,25. Na análise discriminante, observou-se que o escore total da ECD-P diferiu significativamente (P = 0,03, teste t de student) nos grupos de crianças com cárie (28,1 ± 8,3) comparadas às sem cárie (25,4 ± 9,2). Houve correlação significante (P = 0,004) entre o escore total na ECD-P e o número de dentes cariados que cada criança apresentou (Spearman’srho 0,188). Este estudo mostrou que a versão brasileira da PCS-P, denominada ECD-P, apresentou propriedades psicométricas marginais e evidencia que a ECD-P necessita de ajustes para melhorar suas propriedades psicométricas.
Adenoma pleomórfico de glândulas salivares menores: investigação do potencial neoplásico baseado na apoptose, atividade mucosecretora e proliferação celular
(Universidade Federal de Goiás, 2014-02-14) Ferreira, Jean Carlos Barbosa; Batista, Aline Carvalho; Mendonça, Elismauro Francisco; http://lattes.cnpq.br/2305019128015847; Mendonça, Elismauro Francisco de; Garcia, Robson Rodrigues; Pereira, Claudio Maranhão
Pleomorphic adenoma (PA) is the most common salivary gland tumor, however its etiopathogenesis is unclear, as well as your neoplastic potential. Studies have already been done investigating apoptosis, mucosecretory activity and proliferation cellular, although these studies are controversial. The aim of this study was to investigate the neoplastic potential of the PA of minor oral salivary glands measured by apoptosis (Bcl-2, Bax and p53), mucosecretory activity (MUC1), and cellular proliferation (Ki-67). Thirty-one cases of PA of the oral cavity and 4 controls (C) taken from normal oral minor salivary glands were analyzed by immunohistochemistry technique. The proteins were detected utilizing a semi-quantitative method (scores) as follows: (-) negative ≤ 5%, (+) low 6–25%, (++) moderate 26–50% and (+++) high >50% of positive tumour cells. The apoptotic indices were evaluated by the ratio Bcl-2/Bax. Non-parametric comparison and correlation tests were used for analysis. The data showed high staining of anti-apoptotic protein Bcl-2 in both groups (PA= 57.9%; C=67.7%) and an expression significantly lower of pro-apoptotic protein Bax (PA=22.7%; C=97.7%) and MUC1 (PA=14%; C=82.3%) in PA than in C (p<0.001). On the other hand, we observed a similar expression of Ki-67 and p53 proteins (≤ 5%) in both PA and C. In PA, only 2 cases showed the ratio Bcl-2/Bax <1. There was no difference in cellular expression with regard to clinical variables clinical and outcome (p>0.05). The neoplastic potential of PA can be associated with an imbalance in apoptotic processes and a lower index of proliferation cellular and that the mucosecretory activity does not play a significant role in primary PA.
Adesão de pacientes com câncer oral a um protocolo de preparo odontológico: impacto na interrupção da radioterapia e na sobrevida
(Universidade Federal de Goiás, 2013-08-23) Morais, Marilia Oliveira; Mendonça, Elismauro Francisco de; http://lattes.cnpq.br/2305019128015847; Mendonça, Elismauro Francisco de; Mota, Dálete Delalibera Corrêa de Faria; Silva, Maria Alves Garcia Santos
Therapeutic modalities for the treatment of oral cancer result in local adverse effects that can cause interruptions of the radiotherapy and consequently to influence in the patient survival. For the reduction and control of the adverse effects, Dental Care Protocol is applied to patients with oral cancer by dental surgeon team before, during and after radiotherapy and chemotherapy. Objective: The aim of this study was to investigate the adhesion of patients with oral cancer to a Dental Care Protocol and its Impact in the interruption and survival. Patients and methods: In this study 133 cases of oral cancer undergoing radiotherapy were selected. The patients were classified according to the period of dental adhesion: no adhesion (group I), adhesion less than or equal to 6 months (group II) and adhesion higher than 6 months (group III). Clinic and pathological aspects, occurrence of interruption of radiotherapy, disease-free survival and overall survival were investigated. Results: The incidence of radiotherapy interruption due to symptoms was statistically significant in group III compared to group I (p = 0.01). The frequency and duration of interruption due to symptoms were not statistically significant between groups. The conclusion of radiotherapy rate was statistically significant in the group that exceeded 6 months of dental adhesion (p = 0.02). Patient’s survival was higher in group III (p = 0.01) when compared to the other groups. Conclusion: The adhesion to a dental care protocol did not have any impact on the radiotherapy interruption due to the occurrence of symptoms, however, patients who had higher adhesion to the Dental Care Protocol showed a higher rate of disease-free survival and overall survival.

(Universidade Federal de Goiás, 2019-02-22) Loureiro, Marco Antonio Zaiden; Siqueira, Patricia Correia de; http://lattes.cnpq.br/1916908532016188; Decurcio, Daniel de Almeida; http://lattes.cnpq.br/4640062828556657; Estrela, Carlos; Alencar, Ana Helena Gonçalves de; Decurcio, Daniel de Almeida
Objective: To compare the volume of dental tissue removed after guided and conventional endodontic access in maxillary molars. Material and Method: Twenty first and second upper human extracted molars were selected and submitted to cone beam computed tomography (CBCT). The teeth were divided into two groups: conventional endodontic access (G1) and guided endodontic access (G2). The DICOM files obtained by the CBCT examination were transferred to InVesalius® software to calculate the initial volume (IV) of each tooth. The teeth of the G2 were scanned with the 3SHAPE® device for the planning of the guides, and the same ones printed in Straumann® CARES® P30 3D printer. The accesses in the G1 group were realized with spherical diamond tips and Endo Z drill in high rotation, and in group G2 spherical diamond tips were used in high rotation and drills of 1,3mm in engine of implantology. New CBCT tests were performed after the endodontic accesses to calculate the final volume of each sample unit (FV). The volume of dental tissue removed (VR) was calculated by the formula: VR = IV-FV. Volumes between groups were compared by Student's T-test for independent samples. Results: There was a mean volume reduction of 62.526 mm³ (5.86%) in conventional access and 45.677 mm³ (4.11%) in guided access, with difference between groups (p = 0.004). Conclusion: Guided endodontic access in extracted human upper molars preserves a larger volume of dental tissue when compared to conventional endodontic access.
Análise da hibridização dentinária na alteração cromática coronária frente ao uso de cimentos obturadores do canal radicular e cimento portland
(Universidade Federal de Goiás, 2021-02-22) Chaves, Lucas Silva; Estrela, Carlos; http://lattes.cnpq.br/3611967334176683; Estrela, Carlos; Decurcio, Daniel de Almeida; Guedes, Orlando Aguirre
Objective: This study evaluated the influence of dentin hybridization in the coronary chromatic alteration of bovine teeth when using different endodontic cements based on calcium silicate and Portland cement. Material and method: 200 bovine central incisors were divided into two groups: G1 with the presence of dentin hybridization and G2 without the presence of dentin hybridization. The teeth were subjected to colorimetric analysis using the Easyshade spectrophotometer at four different times: determining the color of the dental substrate before root canal filling; seven days after root canal filling, sixty days after root canal filling and one hundred eighty days after root canal filling. The data were tabulated and evaluated for normality and homogeneity by the Shapiro-Wilk and Levene tests, respectively. Two-way analysis of variance was performed, with Sidak's post-test for multiple comparisons, with a significance level of 5% (α = 0.05). Results: Dentin hybridization influenced the coronary chromatic alteration of Sealapex cement after 7 days and in Bio-C Sealer and AH Plus cements after 60 days, but all endodontic cements caused clinically noticeable chromatic changes after 7 days, 60 days and 180 days, independent of hybridization. After 7 days, the AH Plus endodontic cement obtained the highest ΔE * when hybridized and the Endofill endodontic cement obtained the highest ΔE * when not hybridized. After 60 days, the AH Plus endodontic cement obtained the highest ΔE * when hybridized and non-hybridized. After 180 days, Sealapex endodontic cement obtained the highest ΔE * when hybridized and AH Plus endodontic cement obtained the highest ΔE * when not hybridized. Conclusion: All endodontic cements caused clinically perceptible chromatic changes in the endodontically treated teeth after 7 days, 60 days and 180 days, regardless of dentin hybridization. The studied endodontic cements behaved in different ways regarding a coronary chromatic alteration, being difficult to predict a unique behavior.
Análise das jurisprudências sobre alegado erro odontológico em tratamentos ortodônticos no Brasil
(Universidade Federal de Goiás, 2017-03-20) Picoli, Fernando Fortes; Prado, Mauro Machado do; http://lattes.cnpq.br/8157761580237561; Silva, Rhonan Ferreira da; http://lattes.cnpq.br/4551378145791273; Silva, Rhonan Ferreira da; http://lattes.cnpq.br/4551378145791273; Paranhos, Luiz Eduardo; Valladares Neto, José; Li, An Tien; Decúrcio, Daniel de Almeida
Once the dentist is inserted in a social context, his professional performance is mediated by laws that may require compensation, as financial claims, for the damages caused to the patients. The literature has pointed out a significant increase in the lawsuits that dentists are involved, being orthodontics among the specialties most enrolled in these litigations. This study aimed to analyze the judicial decisions on second instance that involved Orthodontics in alleged dental error in Brazil. An online search was done on the virtual pages of the Courts of Justice of the Brazilian states and the Federal District, searching for decisions that were published until December 31st, and that had the orthodontic treatment as central focus. The following keywords were used in the search: erro AND odontológico; erro AND odontologia; ortodontia; aparelho AND dentário; dentário; ortodôntico. Data regarding the profile of the parties, monetary amounts involved, contractual obligation, type of civil liability considered and the judgments of judicial decisions were collected. A total of 319 judgments that were in line with the scope of research were found, and in 38.6% of them, the main reason for initiating the lawsuit was dissatisfaction with the orthodontic treatment. In 52.4% of the cases, there was absolution of the dentist. The conviction in the first instance and the fact that orthodontic treatment was considered as a contractual obligation of result had a statistically significant influence (p <0.05) on the conviction frequencies of the professionals in the second instance. Through this study, it can be concluded that, in Brazil, most patients who demand dentists for malpractice in orthodontic therapy claimed to be dissatisfied with the treatment outcome. The conviction on the singular jury decision and the contractual obligation of the Orthodontics influenced the frequency of second-degree convictions.
Análise das propriedades mecânicas, grau de conversão e profundidade de polimerização de resinas compostas polimerizadas com diferentes unidades fotoativadoras de LED
(Universidade Federal de Goiás, 2021-02-24) Almeida, Laís da Mata; Veríssimo, Crisnicaw; http://lattes.cnpq.br/2811678434269373; Veríssimo, Crisnicaw; Lopes, Lawrence Gonzaga; Soares, Carlos José
This study analyzed the irradiance and spectrum by emission spectrophotometry (MARC-RC), characterized the light beams (Beam Profile), as well as determined the Knoop microhardness (KHN), the modulus of elasticity (GPa), the degree of conversion ( %), the flexural strength of 3 points (MPa) and the polymerization depth with elasticity modulus of a composite (Filtek Z350 XT) photopolymerized with 5 different types of LED curing units. Of these, three types were not certified by ANVISA and Inmetro, Dental Wireless (E1), Li A180 (E2) and Lyang Ya (E3), and two with certification, VALO Cordless - Ultradent (VL) and Elipar Deep-Cure L - 3 Oral Care (EL). The characterization was carried out by determining irradiance (mW / cm²), emission spectrum (mW / cm² / nm) and radiant exposure (J / cm²) using the MARC Resin Calibrator (MARC-RC, BlueLight). The Beam Profile of the different photoactivating units was made by means of a laser beam profile reader (Beam Profile). 50 specimens were produced for testing microhardness and modulus of elasticity. Each experimental group was polymerized with a photoactivator unit. Microhardness (KHN) was obtained by averaging five indentations on each surface. The modulus of elasticity was obtained by measuring the major and minor diagonals of each indentation. The degree of conversion was obtained by the FTIR / ATR test with 25 specimens. The 3-point flexural strength test (n = 50) was performed using a load in the center of the sample with a constant speed of 0.5 mm / min until fracture. The maximum load was recorded in Newtons. The depth of polymerization of the restoration was evaluated by Knoop microhardness using the average indentations in the regions: mesial, center and distal of healthy human molars prepared in Class II and restored using an oblique incremental technique. The modulus of elasticity of the polymerization depth of the restoration was obtained in the same way as the previous microhardness test. The test data were subjected to the normality test (Shapiro-wilk) followed by Factor analysis of variance (One-way ANOVA), Two-factor analysis of variance (Two-way ANOVA), Tukey HSD test (α = 0, 05) and multiple linear regression. In all tests, the groups showed statistically significant differences between them (p <0.001). The non-certified units (E1, E2 and E3) presented nonhomogeneous light beam profiles with concentrated irradiance in the center of the active tips. E3 showed greater irradiance when compared to the other photoactivating units. VL and EL showed larger diameters between the different photoactivating units. In the microhardness (KHN) and elastic modulus (GPa) tests, VL presented the highest mean values in both and E1, the lowest mean values. VL showed higher values of degree of conversion (%) when compared to EL and E3. The highest values of flexural strength (MPa) were E3 when compared to the other groups, being statistically similar to the VL and E2 groups. At depths closer to the pulp wall, lower mean values of microhardness and modulus of elasticity were obtained. And, the highest mean values of microhardness and modulus of elasticity were found in the occlusal regions (1mm). The interaction between microhardness and modulus of elasticity showed a very strong and proportional positive correlation according to the different depths tested. The analysis of the tests indicated that between microhardness (KHN) and depth of the restoration, a weak positive correlation was obtained and there was no association with irradiance (mW / cm²). The modulus of elasticity (GPa) was not related to the depth of the restoration and to the irradiance (mW / cm²).
Análise das relações de poder na política nacional de saúde bucal: o dito e o visto
(Universidade Federal de Goiás, 2008-04-08) ANDRADE, Flávia Reis de; MARCELO, Vânia Cristina; http://lattes.cnpq.br/6650368201862218
In order to consolidate the principles underlying the Brazilian Unified Health System (Sistema Único de Saúde SUS) and with the aim of acting on evidence arising out of epidemiological research in dental health, the Ministry for Health decided to structure the National Policy for Dental Health (NPDH). This study sets out to analyze the power relationships in the drawing up of the NPDH. It is a descriptive study which uses the qualitative method as its approach. The data was obtained through individual semi-structured interviews with 15 participants. The content analysis technique was used for the interpretative examination of the material transcribed. The following categories emerged: participant actors, type of participation, initial outline, (re)discussion lists, political context, present impasses and perspectives. The participant actors were divided into two groups: individual and collective. The former, a coherent group, was made up of people who identified with the victorious political project of the 2002 presidential elections, and who had undoubtedly struggled to build the SUS. It was the task of the second group to give approval to what the first had expounded. The interviewees were influential in the shaping of the NPDH, both through the research they undertook (academy) and through the movements in which they participated (services, militancy). It is impossible to define precisely the moment when the drawing up of the NPDH started, as it was a slow process taking place over at least a quarter of a century. The most visible milestone for the beginning of the broad official and unofficial debates which outlined the Policy, was the result of a series of reflections starting with the Movement for Sanitary Reform. Thus, the NPDH is made up of a set of deliberations arising out of different moments of discussion, but especially the meeting held in the Municipality of São Paulo, following on the election results of Luiz Inácio Lula da Silva s campaign for Presidency of the Republic in 2002. This meeting defined the proposal presented to the members of the Governmental Transition Commission and it marked the beginning of a period of intense normative work by the Health Ministry s Advisory Commission to the National Coordination of Dental Health. This resulted in the drawing up of a document entitled Guidelines on the National Policy for Dental Health , ratified by the 3rd National Conference on Dental Health. The NPDH now presents symptoms of growth as well as those of early degeneration. As potential internal weaknesses, one can cite the improper management of financial resources in particular and the growing tendency of the NPDH to be characterized as a provider of specialized odontological services. However, the greatest preoccupation is that the people who did not in fact participate in drawing up the Policy (for lack of opportunity) are today the pillars of its consolidation. Those who try to understand the process of drawing up the NPDH frequently come up against the nouns group and consensus. This therefore shows a clear approximation to the Arendtian concept of power. However, the present preoccupying indexes of the internal degeneration of the Advisory Commission would point towards another form of power in the implantation phase of the National Policy for Dental Health.
Análise de medidas faciais utilizadas na determinação da largura dos dentes anteriores superiores
(Universidade Federal de Goiás, 2014-02-14) Daher, Mariana Rodrigues Gil; Torres, Érica Miranda de; http://lattes.cnpq.br/6356663266303896; Torres, Érica Miranda de; Barata , Terezinha de Jesus Esteves; Cardoso, Paula de Carvalho
The aim of this study was to evaluate dental and facial anthropometric measures that may assist in planning aesthetic smile, especially in determining the width of the maxillary anterior teeth from the facial measurements. Volunteers who had their faces photographed in a standardized manner in postural position and during smiling were selected. Through a reading software images (ImageJ, USA) to measure calibration was made: interpupillary width (LIP); intercantal width (LIC); eye width (LO); face width (LF); interalar width at rest (LIAR); intercomissura width at rest (LICR); width interalar during smiling (LIAS); width intercomissura during smiling (LICs) and distance between the distal of canines during smiling (DCCaparente). Molding of the upper arch was performed to obtain plaster models, in which were measured the distance between the distal of canines obtained by the sum of the individual widths of the maxillary anterior teeth (DCCreal); between the cusp tips of canines (DCCcúspide); and the distance between the distal canine (DCCcurva). The 96 volunteers, 41 males and 55 females, had the measures compared by Student's t test, and statistically significant differences (p <0,001), except for LIC, with higher values for males. By means of the Pearson Correlation test correlations between facial and dental measurements were tested. Significant correlations (p <0,05) were found, however weak, for males: DCCcurva / LF (r = 0,32); DCCaparente / LF (r = 0,37); DCCaparente / LICR (r = 0,35); DCCaparente / LICs (r = 0,43); and for females: DCCaparente / LICR (r = 0,36). The measurements were divided by the dental facial measurements, and vice versa, in order to calculate reasons. The reasons DCCaparente: LICR (0,82) and LICR: DCCaparente (1,22) were statistically similar in males and females (p> 0,05). It was concluded that facial anthropometric measurements may aid in determining the width of the front teeth in front aspect photographs (DCCaparente), which indicates the existence of aesthetic harmony between the parts of the face and teeth. However, these ratios should not be used for exact, mathematical form, but as aids in planning aesthetic smile, since few significant correlations between measures were weak.

INTRODUCTION: Oral lichen planus (OLP) is an immunomediated disease whose diagnosis and treatment can be challenging for clinicians and pathologists. OBJECTIVE: This case series aimed to evaluate the epidemiological, clinical and pathological profile of patients with OLP according to the criteria established by the American Academy of Oral and Maxillofacial Pathology (AAOMP/2016). METHODOLOGY: Sampling was initially established from the analysis of the annotations of the medical records and histopathological reports of patients diagnosed with OLP at the Centro Goiano de Doenças da Boca (CGDB) from 1998 to 2018. Subsequently, the clinical and demographic data of the patients lesions (location and clinical characteristics of the lesion) and the microscopic characterization of the specimens followed the criteria proposed by AAOMP / 2016. In addition, patients were invited to follow up and apply the Oral Health Impact Profile (OHIP-14) instrument to assess quality of life. Statistical analysis was descriptive with absolute and relative values and the Shapiro-Wilk test was used to assess the normality of the data collected in the OHIP-14 and then the groups were compared using the Mann-Whitney test. RESULTS: This case series (n=41) consisted mainly of women (n=29; 70.7%) with a mean age of 45 (±13.6) years. The buccal mucosa (68.2%) was the most affected site. Reticular (n=23; 56.1%) and erosive (n=14; 34.3%) OLP were the most frequent. According to OHIP-14, individuals with OLP at multiple sites of the oral cavity had worse values in the handicap domain (p=0.03). In addition, those patients who did not respond to corticosteroids had higher scores in the psychological discomfort domain (p=0.04). CONCLUSION: The findings of the present study using the AAOMP/2016 criteria are similar to other case series and retrospective studies reported in the literature, where OLP is more common in middle-aged women in reticular form. In addition, OLP, in its most severe clinical forms, seems to influence patients' quality of life.

The aim of this study was to evaluate the knowledge of dentists that perform restorative treatment about the Consent Informed (CI) used in your dental clinical practice and to collect data that would allow subsidize the construction of an CI that can be used in this practice dental. For this, a structured questionnaire was applied to Dentists who perform restorative treatment in order to make a diagnosis of use of relationship and knowledge of the importance of informed consent. After distributing 731 questionnaires, 179 professionals returned these questionnaires. Of the respondents, 169 said that the discipline of forensic dentistry was studied for them at graduation, 128 studied the subject of Ethics and Law for graduate school, 139 received lessons on the importance and composition of CI in restorative practice, and 171 of them claim give verbal explanations of treatment for patients. However, 67 of these professionals do not use the CI, but 165 of all respondents believe that the use of this document may endorse the Dentists in a possible lawsuit. When asked about what information should be explicit in the CI, 157 of these professionals felt it necessary to contain the risks inherent in the type of treatment; 150, the limitations of the case; 138, the obligations of the patient; 85, treatment costs and 76 stages of the restorative treatment. The Dentists also said they talk to their patients about risks or needs associated with restorative treatment, and 143 professionals talk about tooth sensitivity; 140, need for endodontic treatment; 141, risk of restoration fracture / facet; 127, decay; 71, pulp necrosis and 66 dental darkening. These findings showed that although many of the interviewees possess some level of knowledge of the importance of the use of this document, 67 professionals do not use in their clinical practice. However, most of them fulfills the requirements of the Consumer Protection Code (CDC) and the Dental Code of Ethics (CEO), providing verbal explanations of treatment to patients.
Análise microscópica e da imunoexpressão dos marcadores de proliferação celular Ki-67 e Ciclina B1 no epitélio gengival de pacientes sob terapia com nifedipina
(Universidade Federal de Goiás, 2006-02-28) Castro, Luciano Alberto de; Batista, Aline Carvalho; Mendonca, Elismauro Francisco de; http://lattes.cnpq.br/2305019128015847; Mendonça, Elismauro Francisco de; Guimarães, Maria do Carmo Machado; Guilherme, Adérico Santana
Drug induced gingival overgrowth (DIGO) is an adverse effect associated with the chronic use of three main drugs: phenytoin, an anticonvulsant, cyclosporin, an immunosuppressant drug and the pharmacological agents known as calcium channel blockers (CCB). Nifedipine is a calcium channel blocker, which because of its strong vessel dilating action has become widely used in cardiotherapy, in particular for the control of arterial hypertension. The aim of this study is to evaluate the microscopic characteristics and the epithelial proliferation index of gingival tissue in patients undergoing chronic treatment with nifedipine. To do so, twenty samples of gingival tissue of patients undergoing chronic treatment with nifedipine were obtained. The majority of these patients did not present clinically detectable gingival overgrowth. For comparative purposes, nine samples of gingival tissues of healthy patients who did not use drugs associated with gingival overgrowth (control) were used. The samples were microscopically analyzed using hematoxylin-eosin staining, to determine the size of the epithelial rete pegs. To carry out the epithelial proliferation index evaluation, a cellular identification of the Ki-67 and B1 Cyclin proteins was done using the immunohistochemical technique (streptavidin-biotin-peroxidase), as well as the quantification of positive cells (+cells) in mm².The results showed that the epithelial tissue of nifedipine users has considerably longer rete pegs that of the control group (Mann-Whitney, p=0.02). However, with regard to the proliferating activity of the keratinocytes, no significant difference was observed between the two groups (Mann-Whitney, p>0.05). The findings show that the microscopic alterations observed in the epithelium of nifedipine users are not caused by the mitotic activity of the keratinocytes but taking data from the literature into consideration, it is suggested that this increase might be caused by an inhibition of apoptosis rate of these same cells.

The pharynx is an organ that participates in the respiratory and digestive systems. Its peculiar tubular anatomy may be mechanically obstructed, especially due to adenotonsillar hyperplasia. This hyperplasia, when chronic, results in changes in craniofacial growth and development. The present study aimed to perform the threedimensional evaluation, using cone beam computed tomography (CBCT), of 4- to 9- year-old children, with and without indication for adenotonsillectomy (AT) and with maxillary atresia, comparing the measurements and the location of the minimum area of the pharynx, as well as the total pharyngeal volume and the volume of the subregions of the palatine tonsils and adenoids and, additionally, locating the position of the hyoid bone (H) and correlating it with the total pharynx volume and the volume of the subregions of the palatine tonsils and adenoids. For the selection of the nonprobabilistic consecutive sampling, 487 children were screened at the Otorhinolaryngology Outpatient Clinic of the Hospital das Clínicas, School of Medicine of the Universidade Federal de Goiás, from March to December 2017. Inclusion criteria were: age group between 4 and 9 years, presence of maxillary atresia, and balanced face (evaluated by the S line) using facial analysis. Exclusion criteria were: obesity, extensive caries, previous AT, presence of craniofacial syndromes or congenital anomalies, history of traumas or surgeries in the region of head, neck, or face, previous orthopedic/orthodontic treatment, early tooth loss, and dental Class II or III. The diagnosis of maxillary atresia and the other oral conditions were performed by two orthodontists. After selection, the patients were evaluated by an otorhinolaryngologist, who conducted anamnesis, physical examination and flexible nasal endoscopy to diagnose the obstruction due to adenotonsillar hyperplasia. The sample size calculation, considering the minimum area of the pharynx as the primary variable, defined 30 patients in each of the two study groups, the surgical and the non-surgical groups, who underwent the Prick test. Posteriorly, they underwent CBCT exams to evaluate the airflow and position of H. CBCTs were analyzed using the Invivo Dental software to obtain the three-dimensional and two-dimensional measurements of the pharyngeal airway space and the position of H. The age did not show statistical difference between groups (p = 0.111). The surgical group had a higher frequency of male participants. The measurements of total pharyngeal volume (p = 0.038), volume of the adenoid region (p = 0.001), and minimum area of the pharynx (p = 0.011) showed significant statistical differences between the grupos. In the surgical group, the highest frequency of the minimum area of the pharynx was in the adenoid region (60.0%), while in the non-surgical group the highest frequency was in the palatine tonsil region (73.3%). The correlation coefficient between H-Tweed mandibular plane (MP) and the volume of the palatine tonsil region was moderate in the surgical group (r = 0.408; p = 0.025). In conclusion, in this study: the pharyngeal volumes and the volume in the adenoid region were signifcantly reduced in the patients of the surgical group compared to the non-surgical group; the volume corresponding to the palatine tonsil region was similar in both groups; the narrowest pharynx area was located at a higher frequency in the region near the adenoid hyperplasia in the surgical group, whereas in the non-surgical group it was located at a higher frequency in the palatine tonsil region; no significant statistical difference was found for the position of H between the groups, and the correlation between its position and the sagital and vertical cephalometric patterns was weak.
Angiogênese (WT1, CD31 e CD105) e mutação (Gene H3F3A) em lesões centrais de células gigantes agressivas e não agressivas
(Universidade Federal de Goiás, 2019-08-26) Oliveira Filho, Sérgio Alves de; Mendonça, Elismauro Francisco de; http://lattes.cnpq.br/2305019128015847; Mendonça, Elismauro Francisco de; Silva, Fernanda Paula Yamamoto; Costa, César Augusto Sam Tiago Vilanova
A central giant cell lesion (CGCL) is a benign osteolytic lesion that affects gnathic bones and has a controversial etiology, a variable biological behavior, and can be classified as aggressive or nonaggressive. Although it is highly vascularized, there is no consensus about its neoplastic or proliferative vascular origin or whether it is a distinct lesion from a giant cell tumor (GCT). It is speculated that a GCT shares histological features and has a biological behavior similar to aggressive CGCLs. A genetic mutation located in the H3F3A gene codon G34W of the histone H3.3 protein has been found in GCTs; however, little is known about this mutation in CGCLs. The purpose of this study was to evaluate aggressive (n = 9) and nonaggressive (n = 29) CGCL specimens using WT1, CD31 and CD105 (angiogenic) and histone H3.3 G34W (mutational) markers using an immunohistochemistry technique. WT1 was positively expressed in all specimens, both in mononuclear and giant cells, with higher expression in aggressive CGCL mononuclear cells. CD31 and CD105 were expressed on microvessels, and their microvascular density (MVD) was higher in aggressive lesions. The CD105 MVD was higher than the CD31 MVD, indicating a higher degree of neoangiogenesis in both groups compared to the preexisting vascularization. There was no statistically significant difference between angiogenic marker expressions between groups. There was no expression of histone H3.3 gene mutation in aggressive or nonaggressive lesions. In summary, the results indicate that CGCLs are proliferative neoplastic vascular lesions that present a high proliferative angiogenic profile in aggressive and nonaggressive lesions and, despite their biological behavior, do not express histone H3.3 mutation, which characterizes the distinction of GCTs.

Introduction: Dental fear/anxiety (DFA) and dental behavior management problems (DBMP) in dental care are common during procedures performed in early childhood. This relationship between them has been observed in primary studies, that have specifically evaluated the effect of behavior management techniques and/or specific procedures in reducing DFA and DBMP in children under the age of six. Little is known about the impact of early childhood dental experience on DFA and DBMP in older children. Objective: The objective of this scoping review was to map and synthesize the evidence on the impact of early childhood dental treatment DFA and DBMP throughout childhood. Methods: The search for articles was carried out in the electronic databases APA PsycNet, Cochrane, Embase, LILACS, PubMed, Scopus and Google Scholar. For the search, terms related to preschool children, DFA, DBMP, caries, follow-up were combined. There were no restrictions on the language of publication or date of publication. Clinical trials and longitudinal observational studies carried out with children aged between two and six years at baseline were included. Narrative and systematic reviews, cross-sectional studies, case-controls, case reports and series, clinical trial protocols, abstracts in conference proceedings, editorials and opinion pieces were excluded. The process of selecting studies and extracting information was carried out by two researchers. Information on the treatments carried out, management techniques and follow-up time was extracted from the studies and summarized in a chart and text. Results: Out of a total of 742 studies identified, nine were included, of which five were randomized clinical trials, one was a non-randomized clinical trial and three were prospective longitudinal studies. The change in DFA level after dental care in early childhood was measured in six studies. In three there was an improvement. In the others, the DFA level worsened (n=2) or there was no change (n=1). In the other studies, DBMP was measured in isolation or in conjunction with DFA. Of the three, two showed an improvement in behavior. Follow-up times ranged from seven days to 30 months. Conclusion: From the studies selected, it was noted that there is no consensus on the effect of dental treatment carried out in early childhood on DFA and DBMP at future visits. The number of studies is limited, and the methods and results are heterogeneous.

Aim: to evaluate the use of CBCT to determine, in mm3 , the volume of dental tissue removed during endodontic access in human premolars. Materials and methods: For this analysis, CBCT was used in 20 teeth before and after endodontic access, performed with spherical and conical diamond burs. The CBCT used was I-CAT (Imaging Sciences International, Hatfield, PA, USA), with the following setup: 0.25 mm voxel, 13 cm FOV, 30s, 120 kVp and 3,8 mA current. DICOM images were loaded on two softwares, InVesalius® and Materialise Mimics/3-matic®. A 3D reconstruction of the tomography imagens was realized on both softwares, and it was calculated the initial (Vi) and final volume (Vf). The volume of removed tissue (Vr) was calculated through the formula: Vr = Vi – Vf. Results: The calculated data, for softwares Materialise and InVesalius, respectively, were: mean Vi of 441,79 ± 85,08mm3 and 442,01 ± 84,83mm3 ; mean Vf of 426,75 ±83,88mm3 and 426,94 ± 83,75mm3 ; mean Vr of 15,04 ± 4,32mm3 and 15,07 ± 4,16mm3 . No statistically significant diferences were found on the volume calculated on the different softwares in all measures, initial, final and removed. (p>0,05). However, there was a significant difference between the initial and final volume values calculated on the same software (p<0,05). Conclusion: CBCT is a tool that can be used to determine the volume of dental tissue removed during endodontic access, in vitro, associated with specific softwares for this purpose.
