Background: Previous studies have shown that with advancing age the size of the dental pulp cavity is reduced as a result of secondary dentine deposit, so that measurements of this reduction can be used as an indicator of age. Age estimation is one of the indicators used in forensic identification and teeth are biological markers for human age estimation.

Methodology: We measured the height (mm) of the crown (CH = Coronal Height) and the height (mm) of the coronal pulp cavity (CPCH = Coronal pulp cavity height) of premolars and molars of 134 adult Malawians (77 males, 57 females) aged 20 80 years from dental radiographs. The Tooth-Coronal Index (TCI) was computed for each tooth and regressed on real age.

Result: The correlation coefficients ranged from r 0.650 to 0.799 and were significant in both gender, in premolars and molars (P
