Summary
Forensic odontology uses pulp and tooth volume (PTV) ratios from cone-beam computed tomography (CBCT) scans for age estimation. Canine teeth showed the most reliable results for this noninvasive method in the studied population.
Area of Science:
- Forensic Odontology
- Anthropology
- Radiology
Background:
- Age estimation is crucial in forensic odontology for human identification.
- Pulp volume estimation using cone-beam computed tomography (CBCT) offers a noninvasive method applicable across all age groups.
Purpose of the Study:
- To estimate chronological age-based pulp and tooth volume (PTV) ratios in adults from Uttar Pradesh, India.
- To evaluate the efficacy of CBCT and voxel counting software for age estimation.
Main Methods:
- Thirty-six CBCT scans of lateral incisors, canines, and first premolars were analyzed.
- Pulp and tooth volume (PTV) was calculated using image segmentation with Xelis Dental software.
- Regression equations were derived to correlate chronological age with PTV.
Main Results:
- The study established a statistically nonsignificant difference between estimated and chronological ages (P = 1.00).
- Standard errors of age estimates were 11.24 years for lateral incisors, 7.78 years for canines, and 9.89 years for first premolars.
- Canine teeth demonstrated the lowest standard error, indicating higher accuracy.
Conclusions:
- Calculating PTV ratios from CBCT scans is feasible for age estimation in the studied population.
- Canine teeth serve as the most reliable predictor for age estimation in this demographic.
- This noninvasive CBCT-based method supports forensic odontology applications.

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...
