Objective: To evaluate the quality of endodontic obturations performed by students in laboratory activities of the Endodontic Discipline of undergraduate course in Dentistry. Methods: 80 root canal fillings were evaluated in 35 teeth by means of standardized radiographs of birradicular molar teeth and premolars. The quality of the obturation was carefully evaluated in three parameters: (i) apical limit, (ii) homogeneity and (iii) conicity, which were stratified into (E) 0, 1 and 2. E0 and E1 corresponded to a marked and smooth deviation from normality, respectively; while E2 corresponded to the gold standard. Due to the combination of the assigned scores, the obturation was classified as either perfect (FP), satisfactory (ST) or deficient (DP). Thus, with three E2 scores: PF obturation; two E2 scores: ST obturation; and one or no score E2: DF obturation. The associations between variables were analyzed using the Pearson chi-square test (p <0.05). Results: The frequencies of E2 (ideal
condition) scores for homogeneity, apical limit and conicity were 97.5%, 87.5% and 73.8%, respectively (p> 0.05). PF, ST and DF fillings occurred in 63.8%, 33.8% and 2.5% of the cases, respectively. There was therefore no statistically significant association between the distribution of the parameter scores as well as the quality of obturation between the groups of teeth (p> 0.05).
Conclusion: The obturations performed presented an adequate quality standard, with taper being the most critical parameter, especially in the maxillary molars.
