Summary

This summary is machine-generated.

Dental age estimation using Kvaal's method on digital panoramic radiographs is feasible in the Indian population. However, previously established regression equations significantly underestimated chronological age, necessitating new calculations for this demographic.

Forensic Odontology
Radiology
Anthropology

Background:

Accurate age estimation is crucial for legal and ethical reasons.
Dental pulp regression, due to secondary dentin deposition, serves as a reliable age indicator beyond 25 years.
Kvaal et al. pioneered a radiographic method for age estimation based on pulp size.

Purpose of the Study:

To estimate chronological age using Kvaal's method with digital panoramic radiographs.
To validate the existing regression equations from Kvaal et al. in an Indian population.

Main Methods:

A study of 152 individuals aged 14-60 years was conducted.
Measurements were taken from digital panoramic radiographs following Kvaal's method.
New regression formulae were derived, and assessed age was correlated with actual age using Student's t-test.

Main Results:

No significant difference was found between mean chronological and estimated ages.
Kvaal et al.'s original regression equations significantly underestimated chronological age in the study sample.

Conclusions:

The technique of dental age estimation using digital panoramic radiographs is feasible.
The regression equations developed by Kvaal et al. are not directly applicable to the Indian population studied.
