Background: The occurrence of an extra distal root in primary mandibular first molars is relevant clinically for the delivery of optimal care. However, there have been no studies conducted for establishing the prevalence of same in South Indian population. Aim: The aim of the study was to evaluate the prevalence of three-rooted primary mandibular second molars in South Indian children. Materials and Methods: Intraoral periapical radiographs of bilateral primary mandibular second molars, obtained from 77 patients, were investigated for the presence of additional root. A total of 154 primary mandibular second molars were examined. Results: The total occurrence of three-rooted primary mandibular second molar among the study participants was 6.5%. A male:female ratio of 1.5:1 was noted. Three-rooted primary first molar occurrence on the right side was noted to be higher than on the left, with 2.6% having a bilateral occurrence. Conclusion: 6.5% of children have an additional root making it rare entity.
