Resumo
Acceptable therapeutic protocol in dentistry depends on the outcomes obtained with follow up. Operative procedural errors (OPE) may
occur and they represent risk factors able to compromise a tooth or a dental implant. The aim of this study was to detect the OPE in
endodontically treated teeth and dental implants, using cone beam computed tomography (CBCT). Eight hundred and sixteen CBCT
exams were performed between January 2009 and October 2010, and only those which presented endodontically treated teeth and/
or dental implants were selected. The sample was as follows: 195 CBCT exams (n=200 teeth and 200 dental implants), 72 male, 123
female, with mean age of 51 years. In endodontically treated teeth, OPE included underfilling, overfilling, and root perforation; OPE
in dental implants were thread exposures, contact with anatomical structures, and contact with adjacent teeth. Kolmogorov-Smirnov
test was used for statistical analysis, with significance level set at α=0.05. Underfilling, overfilling, and root perforations were detected
in 33.5%, 8% and 4.5% of the teeth, respectively. Dental implants with thread exposures, contact with important anatomical structures
and contact with adjacent teeth were seen in 37.5%, 13% and 6.5% of the cases, respectively. OPE were detected in endodontically
treated teeth and dental implants, and underfilling and thread exposures were the most frequent occurrences, respectively.
