Summary
Dental age assessment using tooth development helps forensic science. In Syrians, specific third molar stages reliably indicate age 14 or 18, aiding forensic age diagnostics.
Area of Science:
- Forensic Anthropology
- Odontology
- Radiology
Background:
- Dental age assessment is crucial in forensic science, relying on tooth mineralization.
- Accurate reference data is needed for diverse populations.
- Orthopantomograms (OPGs) are commonly used for dental age estimation.
Purpose of the Study:
- To enhance age diagnostics accuracy using dental mineralization.
- To establish reference data for the Syrian population in forensic contexts.
- To evaluate the reliability of third and lower second molar development for age estimation.
Main Methods:
- Analysis of 280 OPGs from Syrian individuals (140 males, 140 females) aged 12-25.
- Application of Demirjian's classification system to assess third molars (18, 28, 38, 48) and lower second molars (37, 47).
- Statistical analysis using generalized estimating equation models to determine age probabilities.
Main Results:
- No significant differences in mineralization were found based on jaw side or sex.
- Mineralization stage G in third molars strongly indicates reaching age 14 in the Syrian population.
- Fully developed third molars (stage H) show high probability (82-95%) of individuals being 18 years or older.
Conclusions:
- Specific third molar mineralization stages provide reliable indicators for age assessment at 14 and 18 years in the Syrian population.
- Lower second molar mineralization (stage H) also offers high probability for age 14, though not conclusive.
- These findings enhance forensic age diagnostics by providing population-specific dental reference data.

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.
