Background: Cementum is a hard avascular connective tissue that covers roots of the teeth which is deposited in layers throughout life. Microscopically each layer is seen as a set of alternating dark and light bands called cemental annulations. The objective of the present study is to examine the correlation between the number of cemental lines and age of an individual, and also to find the efficacy of bright field microscopy (BFM), phase-contrast (PH), and polarized (POL) microscopy for counting these annulations. Materials and Methods: Extracted teeth from patients of known age devoid of any pathology were selected, and longitudinal ground sections were prepared. These ground sections were observed under BFM, POL, and PH microscopy. Microphotographs were further magnified using a computer. The dark lines on the cementum were counted using Image Pro Express 6.0 software. Results: PH microscopy showed better correlation (0.9952) between actual and estimated ages in comparison to BFM (0.9760) and POL microscopy (0.9833). Conclusion: Our study showed that PH microscopy can improve the precision of age estimation in forensic identification.
