Age estimation by IBAS image analysis of teeth.

The study of teeth to estimate age in a cadaver or in remains has become widely accepted in legal medicine, especially since the appearance of Gustafson's work in 1950. However, many studies published since that time have questioned the accuracy of these determinations. Computerized image analysis (IBAS) provides much more precise measurements of the parameters involved in these studies. An IBAS I (Kontron) image analysis system was used to study 19 different morphological parameters in midsagittal sections of a total of 173 upper and lower central incisors from as many live subjects. The data thus obtained provide useful information for determining the subject's age.
