简要总结
The aim of this study was to investigate the applicability and accuracy of Drusini’s and Cameriere’s methods of age estimation in Indian adult population.
Method: 150 periapical radiographs pf mandibular second premolar radiographs obtained from dental patients. Measurements of height of pulp chamber and crown and area of pulp chamber and crown will be made. The values obtained will be used to obtain regression co- efficient to apply in Drusini’s and Cameriere’s formula.
Pearson’s correlation coefficients and regression analysis will be used.
