Analysis of endodontic treatment and demographic data in an urban Brazilian population: a 19-year single-center retrospective study

Objective: This study investigated the distribution of endodontic procedures performed by an endodontic specialist in an urban Brazilian population. Material and Methods: A retrospective study was conducted on 8041 patients treated between 2000 and 2018 at a single center. The study evaluated data from clinical and radiographic examinations, endodontic procedures, dental groups, sex, and age. Results: Endodontic retreatment was more frequent in age groups over 30 than in younger groups (p <0.001). The lower first molar was the most affected tooth in the 20 to 49-year-old group. The endodontic treatment group had the highest frequencies of the upper first molar (15.34%) and lower first molar (13.20%). Retreatment was more frequent in the incisor group (p <0.001). No significant differences were observed between males and females regarding endodontic treatment and retreatment. Conclusion: The findings suggest that there was an oscillation in the distribution between endodontic treatment and retreatment over time. Furthermore, the prevalence of the affected dental group varied based on the age group and type of endodontic procedure.
