Summary
Dental analysis offers a reliable method for age determination in forensic investigations. This study developed a formula based on six tooth changes to estimate age with an average accuracy of ±4.43 years.
Area of Science:
- Forensic Anthropology
- Dental Age Estimation
Background:
- Age determination is critical in medicolegal and archaeological contexts.
- Teeth are durable human remains, often preserved in various conditions.
- Dental structures provide valuable indicators for age estimation.
Purpose of the Study:
- To investigate physiological changes in teeth associated with aging.
- To develop a regression formula for estimating age based on dental parameters.
Main Methods:
- Studied 80 individuals (26-70 years old) with 58 men and 22 women.
- Assessed six physiological tooth changes: attrition, periodontosis, secondary dentin deposition, root translucency, cementum apposition, and root resorption.
- Assigned scores (0-3) to each parameter, calculated a total score, and performed regression analysis against known age.
Main Results:
- A regression formula (y = 3.71x + 16.03) was derived to estimate age.
- The average age difference between known and estimated age was ±4.43 years.
- The study demonstrates the potential of combined dental changes for age estimation.
Conclusions:
- The developed regression formula provides a quantifiable method for dental age estimation.
- This approach can aid in forensic identification and age assessment when other methods are unavailable.
- Further research can refine this method for improved accuracy in diverse populations.

01:15Teeth
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 and...

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
