The purpose of this cross sectional study was to determine the prevalence of three rooted permanent first mandibular molar in a sample of southern Pakistani population.


A total of 405 participants were included in this study, out of which 234 were females and 171 were males. A total of 810 peri-apicalradiographs were taken with 30 degree mesial angulation and were evaluated using Digora® Optime software. Prevalence, gender of the participant and symmetry of the mandibular first permanent molars were assessed.


Our findings showed an overall 3.2% prevalence of three rooted mandibular first permanent molar in a sample of Southern Pakistani population. In males, it was 3.5% and in females 3.0%. Overall bilateral prevalence was 1.0%. In males, it was 1.2% and in females 0.9%. Overall prevalence of 2.7% on the right and 1.5% on the left side was found. Chi square test showed P value >0.05 indicating no significant relationship of three roots with gender (male versus female) or sides (right versus left).


Although there is a low prevalence of three rooted mandibular first permanent molar in Southern Pakistani population, but it is significant enough to warrant caution when performing endodontic procedures on these teeth to achieve consistent and desirable results.
