Aim: To evaluate the prevalence of three-rooted primary mandibular first molars in children of Davangere, Karnataka, India. Materials and methods: Children aged 3 to 10 years, who reported to the Department of Pedodontics and Preventive Dentistry, during the period of January to December 2014 were included in the study. Intraoral periapical radiographs of bilateral primary mandibular first molars, obtained from 77 patients, were investigated for the presence of an additional root. A total of 154 primary mandibular first molars were examined. Results: The total occurrence of three rooted primary mandibular first molar among the study subjects was 1.3%. There was noted an equal distribution among boys and girls (1:1). Both the three rooted primary first molar occurred on the right side with no bilateral occurrence noted. Conclusion: Primary mandibular first molar can display several anatomical variations, most frequently supernumerary root located distolingually. Hence, pedodontists should be alert in the identification of additional roots and to make necessary treatment modifications. Clinical significance: An awareness and understanding of the presence of additional roots and unusual root canal morphology are essential as it determines the successful outcome of the endodontic treatment.
