Abstract

Cementum in human tooth is a hard tissue in its root deposited around dentin in layers throughout the life. Microscopically each layer is seen as a set of alternating dark and light bands and called as Cemental Annulations. Intact teeth obtained from subjects of either sex and of known ages processed by ground sectioning manually and mounted on a glass slide. The cemental annulations were then counted by light microscope using CCTV Screen, at the junction of cervical with middle third of root. Age was then determined by adding the eruption age in years of tooth in study to the annulations counted. This was found to be matching with actual age almost to an accuracy of +/- 1-2 years.
