Aims and Objectives: The aim of this study was to estimate the age of the patients belonging to the age group of 15 - 55 years, attending the Department of Oral Medicine and Radiology, St. Joseph Dental College and Hospital, Eluru, based on the radiographic evaluation of the pulp cavity width of the maxillary central incisors. Materials and Methods: The study group comprised of 120 subjects. Intraoral periapical radiographs of the maxillary central incisors were taken for all subjects, using the conventional paralleling angle technique and the pulp cavity width was measured at the cervical and middle third using a digital vernier caliper. The data obtained was subjected to correlation and regression analysis. Results: A negative linear relationship was obtained between the age and pulp cavity width (cervical third, r = -0.459 and middle third, r = -0.704). Cubic regression analysis was done and the regression formulae were obtained. A mean difference of 0.1 years was obtained between the estimated age and real age, indicating the reliability of the derived formula. Conclusion: It can be concluded that the width of the pulp cavity of maxillary central incisors are reliable for estimation of age
