Teeth

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...

Area of Science:

  • Forensic Odontology
  • Anthropology
  • Radiology

Background:

  • Accurate age estimation is crucial in forensic and anthropological contexts.
  • Dental development, particularly third molar maturation, is a reliable indicator of chronological age.
  • Demirjian's method provides a standardized approach to assess dental maturity.

Purpose of the Study:

  • To correlate chronological age with dental age using Demirjian's method.
  • To evaluate the correlation between third molar development on orthopantomograms and age estimation.
  • To investigate sex-based differences in dental development stages.

Main Methods:

  • Radiological cross-sectional study of 231 patients aged 10-25 years.
  • Digital orthopantomograms were utilized for analysis.
  • Simple random sampling ensured representative subject selection.

Main Results:

  • Significant sex-based differences in third molar development stages were observed in both maxilla and mandible.
  • In the maxilla, stages A-E were reached earlier in males, while stages F-H were earlier in females.
  • Mandibular development showed earlier attainment of stages B, C, E-F in males and A, D in females.

Conclusions:

  • Third molar development stages correlate with chronological age.
  • Sex influences the timing of third molar development, with distinct patterns in maxilla and mandible.
  • Orthopantomogram assessment of third molar development is a valuable tool for age estimation.
