This is a community based study of the times of eruption of permanent teeth to establish the age of an individual. The study is based on dental examination of 1008 subjects in the age group 5-14 years, residing in Tirupati, Andhra Pradesh, India. The median age of eruption was computed based on the concept of "Ex" which is defined as the age at which a specified percentage of individuals show eruption of a given permanent tooth. The median age "E50" was computed by transformation of percentages to probits and plotting a graph between age and probits. E50 was computed graphically corresponding to a probits value of 5.0 or 50%. A mathematical regression equation [Kusri's] was computed for each graph. The age of an individual can be computed based on the E50 value of the permanent tooth which erupted last. The probability of the given individual being above or below the assessed age can be estimated by referring to graph and probit transformation table.
