Welcome to the website for the Subadult Dental Age Estimation project. This project is a collaborative effort between Drs. Nicholas P Herrmann (Texas State University) and Joseph T Hefner (Michigan State University). This project is funded by the National Institute of Justice (Award number 2018-DU-BX-0182).

The goal of this project was to provide forensic practitioners with an accurate age estimation method based on a large, demographically diverse, modern subadult sample that captures the variation in dental development. NIJ funding allowed for the collection of a large number radiographic images of modern living subadults from different populations in the United States, Europe, and South Africa. Dental development data is collected from each individual to establish a reference dataset for modeling the best age-at-transition values for each tooth and population group.

A publicly available analytical tool was developed using the new parameters. The analytical tool provides a user-friendly platform for estimating age in subadult individuals based on dental development scores. You can download the analytical tool at our project Github.

We are always searching for new datasets to expand and diversify the reference material. If you would like to contribute data or have a dental radiographic dataset, please feel free to contact the project.
