Background:- Cementum (hard tissue of root), is deposited in layers around the dentin all throughout life. Root cementum is visible as alternate light and dark rings known as incremental lines of cementum under light microscopy. These annulations can be reliably used for age estimation in forensic science.
Aim & Objective:-To determine age estimation of human skeleton by cemental annulations of extracted tooth. The primary objectives of the study were to count number of cemental annulation of freshly extracted human teeth after longitudinal cross-section and to compare the results with actual age of the patients.
Materials & Method:-30teeth were selected and sectioned longitudinally. Sections were ground, mounted and viewed under a bright light microscope. The area selected for counting was photographed under 4X &10X objectives, cemental lines were counted and added to the eruption age of that patient, to obtain the chronological age.
Results:-Mean estimated age (MEA) was 45.95 years and mean actual age (MAA) was 45.42 years. The difference in the values between actual and estimated age was seen to be varying from +6 years to -3 years (approximately 9 years difference). Standard deviation was 2.77, z-value of 0.5 and p-value was 0.62 which was not significant. Correlation co-efficient showed a value of 0.98, proving strong positive correlation between the both the groups.
Conclusion:- The application of cemental annulations to determine age estimation suggestively serves as a valuable aid in forensic dentistry to identify the approximate age of an individual,
