Aims: The aim of the present study is to evaluate the efficacy of the root length and neck diameter of teeth, a new odontometric parameter in gender determination. Materials and Method: 120 anterior teeth from male patients and 120 anterior teeth from female patients of 22 to 80 years of age extracted tooth collected. Root length measured from buccal side, Mesial side, distal side and means of proximal surfaces. Neck diameter measerd from mesiodistally and buco-lingually. Neck circumference measured from bucco-lingual and mesiodistal crest of curvature. Root length, neck diameter and neck circumference compared between male and female. Results: Mandibular central incisors of male patient have mesial, distal & mean proximal root length as well as mesiodistal & buccolingual neck diameter and neck circumference measured at mesiodistally was significantly higher than females and Mandibular lateral incisors of male patients have buccal, mesial & mean proximal root length as well as mesiodistal neck diameter and neck circumference measured at buccolingually was significantly higher than females. Conclusion: Root length, neck diameter and circumference of Mandibular central and Mandibular lateral incisors are significantly higher in male than females. Mandibular central and Mandibular lateral incisors are important teeth to identify the gender in forensic odontology. Root length, neck diameter and neck circumferences are more stable and valuable odontometric parameter in gender determination in forensic odontology.
