Summary
Dental measurements can help determine sex with 70.5% accuracy in Brazilians. Canine tooth measurements correlate with stature, aiding in human identification and forensic anthropology.
Area of Science:
- Forensic Anthropology
- Dental Forensics
- Human Identification
Background:
- Stature and sex determination are crucial for criminal profiling and human identification.
- Teeth offer unique and durable characteristics valuable in forensic investigations.
Purpose of the Study:
- To investigate the correlation between dental anthropometry and stature and sex determination.
- To assess the utility of dental measurements in forensic anthropology for Brazilians.
Main Methods:
- Linear dental measurements (mid distal, incisor cervical) of upper right teeth were taken from 200 Brazilians (100 male, 100 female) aged 18-30.
- Digital calipers and stadiometers were used for measurements; statistical analyses included Kolmogorov-Smirnov, Pearson correlation, and Stepwise-Forward logistic regression.
Main Results:
- All dental measurements exhibited sexual dimorphism.
- Lateral incisor and canine tooth measurements were statistically significant (P ≤ 0.001).
- A model for sex determination achieved 70.5% accuracy.
Conclusions:
- Dental measurements are effective tools for gender identification.
- Canine tooth measurements showed a strong correlation with stature, though a predictive model was not established.
- Findings support the use of dental anthropometry in anthropological studies in Brazil.

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...
