Lower third molar development in relation to skeletal maturity and chronological age

Area of Science:

• Dentistry
• Anthropology
• Radiology

Background:

• Assessing developmental stages is crucial in orthodontics and forensic anthropology.
• Third molars (wisdom teeth) are often used as indicators of dental and skeletal maturity.

Purpose of the Study:

• To investigate the longitudinal development of lower third molar anlage.
• To correlate this dental development with chronological age and skeletal maturation stages.

Main Methods:

• Longitudinal study design.
• Assessment of lower third molar development.
• Evaluation of skeletal maturation using hand epiphyses mineralization.
• Correlation analysis between dental and skeletal data.

Main Results:

• Significant correlations were observed between lower third molar development and both chronological age and skeletal maturation.
• Lower third molar development generally aligns with skeletal maturation stages.
• A notable percentage (11%) of subjects exhibited missing lower third molars.

Conclusions:

• Lower third molar development serves as a reliable indicator of skeletal maturation.
• The findings have implications for age estimation and orthodontic assessments.
• The prevalence of hypodontia (missing teeth) in third molars warrants attention.
