Introduction: Nutrient canals are anatomic structures of the alveolar bone through which neurovascular elements transit to supply teeth and supporting structures. Dental identification using nutrient canal of the mandibular alveolar process as the most compelling anatomic feature for antemortem–postmortem radiographic comparison can be potentially used in forensic identification. Aim: The aim of the present study was to investigate the correlation between the appearance of nutrient canals as a potential clue to age and gender determination. Materials and Methods: One hundred and twenty patients, 60 males and 60 females, were selected in the 11–60-year age group. Systemic disease, especially hypertension, was ruled out in the patients. Periapical radiographs were taken from mandibular anterior cuspid central incisor region because nutrient canals are commonly observed in this area. Data obtained was analyzed by SPSS software and various statistical analysis were carried out. Results: Study revealed nutrient canals to be commonly seen in females compared to males. Males had maximum canals in the age group of 21–30-year whereas females in the age group of 31–40 years had the maximum canals. Conclusion: Significant correlation was seen between the gender and nutrient canals whereas no significant correlation existed between the age and presence of nutrient canals.
