Dental Age estimation through Teeth and Cementum annulations: A Literature Review and Update

Dr. Garima Singh Tomar, Dr. Shobhit Singh Tomar

Abstract :

Teeth can survive for several thousands of years and can reflect age changes from the cradle to the grave. Teeth have been used for age determination in several ways, of which, estimation of cementum annulations is an important technique. Cementum formation is a continuous process that occurs throughout the life of humans and animals. Hence, with age, the cementum increases in width. During this formation, hypermineralized layers of extracellular matrix alternate with less mineralized layers. These changes in cementogenesis result in incremental lines. These incremental lines, or annulations, are similar to the macroscopic visible annual rings that are commonly seen in trees and are useful for estimating the age at death. This article reviews the use of human teeth in general and human tooth cementum annulations for age estimation.
