Secondary dentin deposition occurs as the age advances and can be measured by calculating the reduction in pulp chamber through Noninvasive radiograph techniques.<\/jats:p><\/jats:sec><jats:sec><jats:title>Aim:<\/jats:title><jats:p>The aim is to derive precise population specific formulae for age estimation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods:<\/jats:title><jats:p>Digitalized Orthopantomography of 150 subjects, was retrieved. The subjects were divided into study and test group.
