Age estimation by pulp/tooth area ratio in canines: Study of a Portuguese sample to test Cameriere's method

The common regression model, describing age as a linear function of RAu and RAl, yielded the following linear regression formulas: Age = 100.598-544.433 RAu; Age = 91.362-480.901 RAl, and explained 86% and 93% of total variance, respectively. Mean prediction errors were ME = 2.68 years and 2.73 years, respectively.
