Summary
The Tooth Coronal Index (TCI) offers an easy method for age estimation in forensic odontology. Regression formulas showed higher accuracy for males aged 31-40 years.
Area of Science:
- Forensic Odontology
- Anthropology
- Radiology
Background:
- Age estimation is vital in forensic odontology.
- The Tooth Coronal Index (TCI) is a recognized method for age determination.
- Evaluating TCI's effectiveness in diverse populations is crucial.
Purpose of the Study:
- To assess the efficacy of the Tooth Coronal Index (TCI) for age estimation.
- To analyze TCI accuracy across different age groups and genders.
- To determine the reliability of TCI in forensic age assessment.
Main Methods:
- Retrospective analysis of 700 digital panoramic radiographs.
- Calculation of TCI for mandibular first premolars.
- Statistical analysis including bivariate correlation, linear regression, and ANOVA.
Main Results:
- TCI showed variability in accuracy, with underestimation in younger males and overestimation in older males.
- Females aged 31-40 years exhibited the least difference between actual and TCI-estimated age.
- Significant differences in TCI were observed across female age groups, but not consistently in males.
Conclusions:
- TCI is a practical, non-invasive method for forensic age estimation.
- Regression formulas derived from this study demonstrated improved accuracy for males aged 31-40 years.
- Further research may refine TCI application across different demographics.

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...

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...
