# Estimation of age using pulp/tooth area ratio using orthopantomographs and intra-oral periapical radiographs

## TL;DR

This paper explores using the pulp/tooth area ratio in teeth to estimate age through various statistical models in forensic dentistry.

## Contribution

The study highlights multiple regression as the most reliable method for age estimation using the pulp/tooth area ratio.

## Key findings

- The pulp/tooth area ratio of maxillary canines is directly linked to age estimation.
- Multiple regression models are found to be the most reliable for age estimation in forensic dentistry.

## Abstract

Teeth are crucial for assessing age, as they remain intact even after death in forensic dentistry. Various regression models, such as
polynomial regression, new robust regression equations, multiple linear regression models and partial least squares linear regression,
are used to determine age. The pulp/tooth area ratio (AR) of maxillary canines is a direct link between age and the subject's age,
making multiple regressions the most reliable method. Teeth hardness and invariant changes in their structure also strengthen teeth's
applicability in estimating age. These statistical methods are suitable for both forensic and clinical applications, making them
suitable for both forensic and clinical applications.
