This study shows that epithelial attachment level, used as age determinatio
n criterion in Lamendin's method, is not reliable for adults of either sex
above the age of 49 years with periodontal diseases in any quadrant. The un
derestimation of calculated age increases from 7 to 19 years with chronolog
ical age. On the other hand, the present paper confirms the pertinence of d
entin translucency as an age indicator in Lamendin's method. (C) 2001 Elsev
