    Evidence about the influence of contextual factors of schools and municipalities on the oral health of adolescents is scarce, with important gaps in relation to the school environment. The aim of this study was to investigate associations between the potential support of schools for oral health promotion, the educational quality of the school and oral health outcomes among adolescents in the Brazilian State Capitals. The study was cross-sectional, with individual and aggregated approaches. Data were obtained from the Brazilian National Adolescent School-Based Health Survey (PeNSE) and the Basic Education Development Index (IDEB), conducted in 2015, in addition to other secondary sources. The individual variables referred to students in the 9th grade of elementary schools: sociodemographic, prevalence of dental pain and oral health-related behaviours (frequencies of dental visits, toothbrushing, and soft drinks and sweets consumption, cigarette and alcoholic beverages experimentation). The contextual variables were related to schools, Brazilian capitals and regions (educational quality of the school – measured by IDEB, Human Development Index - HDI and Gini Index). The analyses were carried out in three steps. In step 1, the Oral Health Promoting School Environment (OHPSE) indicator was obtained using the Categorical Principal Components Analysis (CATPCA), to measure the potential support of school environment for oral health promotion in public and private schools of the capitals. Bivariate associations (Chi-square test) between OHPSE and contextual variables were verified. In step 2, associations between OHPSE (explanatory variable) and dental pain and oral health-related behaviours (outcome variables) were tested in two-level multi-level mixed-effects Poisson regression. And in step 3, with data aggregated by capitals, associations were verified between IDEB and the outcomes: the OHPSE indicator and its dimensions (in public schools), dental pain and oral health-related risk behaviours. In all steps, the level of significance was 5%. The results were: Step 1 - There was a higher frequency of schools with higher OHPSE in the public schools (58.1%), and in regions and capitals with a lower Gini Index (52.8% / 55.7%) and higher HDI (57.4% / 61.0%), respectively. Step 2 - In the adjusted model, private and public schools with higher OHPSE had 6%, 6% and 4% lower prevalence rates of a “low frequency of annual dental visits” [PR = 0.94 (95%CI 0.90; 0.99)], “high weekly soft drinks consumption” [PR = 0.94 (95%CI 0.89; 0.99)] and “high weekly sweets consumption” [PR = 0.96 (95%CI 0.93; 1.00)], respectively. Schools with intermediate OHPSE had 12% and 8% higher prevalence ratios of a “low daily toothbrushing frequency” [PR = 1.12 (95%CI 1.03; 1.23)] and “cigarette experimentation” [PR = 1.08 (95%CI 1.01; 1.16)]. OHPSE was not associated with dental pain and "alcoholic beverages experimentation". Step 3: IDEB correlated with the OHPSE dimension referred to within-school aspects, with “low daily toothbrushing frequency” and with “low frequency of annual dental visits”. In the adjusted regression model, capitals with the higher IDEB were associated with “low daily toothbrushing frequency” [B = 1.560 (95% CI 0.360; 2.760), p = 0.013; β = 0.519]. It was concluded that were associations between the potential support of school environment for oral health promotion and some oral health outcomes of adolescents in the Brazilian capitals. Higher potentials for oral health promotion (in private and public schools) were related to more favorable behaviours regarding dental visits and consumption of food with added sugars, and less favorable for toothbrushing frequency and cigarette experimentation, while better educational quality (in public schools) was related to low toothbrushing frequency among adolescents. Inequalities among schools regarding oral health promotion were also found, indicating the need to reorient public policies for the oral health of schoolchildren.

    Incidência de desfechos protéticos associados à overdenture mandibular retida por quatro mini-implantes: estudo prospectivo aninhado a ensaio clínico randomizado
    (Universidade Federal de Goiás, 2023-10-20) Silva, Jésio Rodrigues; Leles, Cláudio Rodrigues; http://lattes.cnpq.br/6740286066154410; Leles, Cláudio Rodrigues; Roriz, Virgílio Moreira; Hartmann, Roberto
    The use of mini-implants is gaining popularity due to less surgical complexity and advantages for cases of atrophic mandibles, and a new system of mini-implants was recently launched (Straumann Optiloc Mini-Implant System®). Aim: This prospective study is part of a randomized clinical trial and aimed to evaluate the incidence of prosthetic outcomes and associated factors in completely edentulous patients after the insertion of mandibular overdentures retained by four mini-implants. Methods: Completely edentulous individuals using conventional complete dentures were recruited for the installation of four mini-implants for treatment with mandibular overdenture. The study combined two surgery protocols (flapped or flapless) and loading (immediate or delayed). During follow-up, the incidence of prosthetic complications and maintenance events were recorded at scheduled and unscheduled appointments. Independent variables were considered as age, gender, surgery and loading protocol, and ridge form (CAWOOD & ROWEL, 1988). A classification of prosthetic outcome (six-field protocol) (PAYNE et al., 2001) was assessed at the end of the follow-up period. Descriptive statistical analysis was performed, with measurements of incidence rates, as well as Kaplan-Meier survival analysis and Cox regression, considering the significance level of p<0.05. Results: 74 participants were accompanied, with a mean age of 64 years (35-80 years), and total follow-up time varied between 19 and 26 months. There were a total of 182 prosthetic events in 147 consultations, 88 of which (59.87%) were unscheduled. The most frequent event was the need for minor adjustments to the base of the overdenture (incidence of 38), due to sore spots; followed by minor repairs at the base (incidence of 16); total (incidence of 21) or partial (incidence of 11) exchange of matrices; indirect relining (incidence of 21) due to instability; new intraoral capture (incidence of 8); fracture of the overdenture (n = 1) and tooth fracture (n = 1). The outcome of success was attributed to 69 participants (93.2%). The most significant predictor for the incidence of adjustments was the flapless surgery protocol (p=0.011), and the age was the most one for the incidence of total matrix replacement (p=0.031). There was no statistically significant difference in the incidence of other prosthetic complications with regard to gender, loading protocol, or ridge form (p>0.05). Conclusions: There was a high incidence of prosthetic events, but they were considered acceptable and mostly represented by small adjustments or repairs to the overdenture base in the initial period of treatment. The high survival and success rate of the implant and prosthesis shows that this is a favorable treatment option for this follow-up, and it is recommended to establish scheduled appointments for the expected events. Longer follow-ups are recommended to obtain more representative data regarding prosthetic outcomes.
