Age estimation by teeth periodontosis and transparency: accuracy of Lamendin’s method on a Brazilian sample
Aim: To apply the Lamendin et al. (1992) technique on a Brazilian sample to assess its accuracy on this specific population. Methods: The authors present two measurements in single-rooted teeth: the peridontosis and transparency of the root. Then, these variables are inserted in an equation to estim...
