    The anatomical variations of the root canals in mandibular second molars were determined through Cone Beam CT scans in a dental imaging center. The study was observational and quantitative, with 108 Cone Beam CT scans being studied using the Vertucci and Melton classifications. It was found that the majority of patients had 2 roots on the right side (77.80%) and left side (84.30%). There were 3 canals on the right side (68.50%) and left side (75.90%). Regarding the Vertucci classification for the mesial root, type II was found on the right side (26.90%) and type III on the left side (32.40%). In the distal root, type I was found on both the right side (92.60%) and left side (92.60%). In terms of sex, most female patients presented type I on the mesial root on the right side (16.70%) and type III on the left side (19.40%). The distal root was type I on the right side (50.90%) and left side (50.90%). Regarding the prevalence of the C canal, the right and left sides showed 24.10%. Type I was mostly found on the right side (61.50%) and left side (65.40%), with a higher prevalence in females. In conclusion, there is anatomical variation in the root canals of mandibular second molars.
