Abstract: In forensic science, age estimation is an important step in identifying unidentified cadavers. As teeth are resistant to environmental degradation for long periods of time, they are often used to estimate age. Although there have been many reports of age estimation based on dental morphology, these methods tend to be subjective and cannot be used i n the case of edentulous jaws. In the present study, we developed a new method of age estimation from dental parameters (number of upper teeth [UT], lower teeth [LT], and prostheses [NP]; tooth attrition [TA]; and occlusal area [OA]) and the mandibular angle (MA) measured at proposed an equation for calculating the age. The results show that the mean error of this method is similar to that of previous methods, and even demonstrated improved accuracy in subjects aged >60 years. We also proposed an equation for age estimation from only the MA, and showed that we can perform age estimation even in edentulous cases using this equation. Because our method is superior in its simplicity, objectivity, and applicability when compared with previous methods, we believe our method wll prove useful for age estimation in a wide variety of cases.
