Summary
A new Peruvian formula for dental age estimation using root dentin transparency (RDT) percentage length is more accurate than the Bang and Ramm method. This method offers reliable age estimation for Peruvian individuals.
Area of Science:
- Forensic Anthropology
- Odontology
- Human Identification
Background:
- Dental age estimation is crucial in forensic science.
- Root dentin transparency (RDT) is a reliable indicator of chronological age.
- Existing methods require validation for diverse populations.
Purpose of the Study:
- To evaluate the Bang and Ramm method for age estimation.
- To develop and validate a new age estimation formula for the Peruvian population.
- To assess the utility of RDT length and percentage length for forensic age assessment.
Main Methods:
- Analysis of 248 teeth from 124 Peruvian individuals (30-70 years).
- Digital measurement of root dentin transparency (RDT) length and percentage.
- Development of linear and quadratic regression formulae for age estimation.
Main Results:
- Significant correlation found between chronological age and RDT length (r=0.775) and percentage length (r=0.778).
- Quadratic equations demonstrated higher determination coefficients.
- The new Peruvian formula using RDT percentage length achieved acceptable accuracy (MAE=7.83).
Conclusions:
- The derived Peruvian formula for RDT percentage length is more accurate than the Bang and Ramm method.
- This new formula provides reliable age estimation for Peruvian adults.
- The method is recommended for forensic age assessment in the Peruvian population.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Radioactivity is a spontaneous disintegration of an unstable nuclide and is a random process, as all the nuclei in the sample do not decay simultaneously. The number of disintegrations per unit time is called the activity (A), which is directly proportional to the number of nuclei in the sample. The decay constant (λ) is an average probability of decay per nucleus in unit time.
