Area of Science:

Forensic Anthropology
Dental Age Estimation
Biomaterials Science

Background:

Accurate age estimation is crucial in forensic and anthropological contexts.
Dental metrics, particularly root dentin translucency, have shown potential for age assessment.

Purpose of the Study:

To quantify root dentin translucency (TD length) using digital imaging.
To establish the correlation between TD length and chronological age.
To evaluate the reliability of TD length for age estimation.

Main Methods:

A pilot study analyzed 62 single-rooted permanent teeth.
Tooth sections (250 μm) were digitally scanned and analyzed using Adobe Photoshop.
TD length was measured digitally and correlated with age using regression and Pearson correlation analysis.

Main Results:

A significant positive correlation (r = 0.52, P = 0.0001) was found between TD length and age.
Regression analysis revealed a linear relationship between TD length and age.
No significant difference in TD length was observed between male and female samples.

Conclusions:

Root dentin translucency increases with age, serving as a reliable age estimation parameter.
The digital measurement method for TD length is precise and shows a strong correlation with age.
This refined digital technique offers superior age estimation compared to previous methods.
