Abstract
Background:
Age estimation is important in forensic medicine and odontology for identification of deceased victims and also for crimes and accidents. Various studies have compared the different morphological methods, biochemical methods and radiological methods of age estimation. However, no study has compared the accuracy of a nondestructive (radiographic)method with a destructive (histologic) method.
Aim and Objectives:
Aim of the study was to evaluate and compare the efficacy of the age estimation using pulp to tooth area ratio by radiography and tooth cemental annulations by phase contrast microscopy.
Materials and Methods:
Eighty permanent single-rooted extracted teeth were utilized in the study. The radiographic age was estimated using the pulp/tooth area ratio; histologic age was estimated using tooth cemental annulations. The results of both the methods were compared to evaluate the more accurate method.
Results:
The correlation between actual age and estimated radiographic age was found to be r = 0.92, P = 0.00 (P < 0.001) and correlation between actual age and estimated histologic age was found to be r = 0.97, P = 0.00 (P < 0.001).
Conclusion:
Both the radiographic method and histologic methods can be efficiently used to estimate age, however; we found that the histologic method had better accuracy in age estimation.
