Summary
The Indian formula offers more accurate age estimation from dental development than Demirjian's method in the Gujarati population. Dental maturity is achieved earlier in females than males.
Area of Science:
- Forensic Anthropology
- Odontology
- Radiology
Background:
- Accurate age assessment is vital for postmortem identification.
- Demirjian's method uses eight developmental stages for age estimation in children.
- Dental development stages provide a basis for age determination.
Purpose of the Study:
- To evaluate the reliability of age estimation using Demirjian's eight teeth method.
- To compare French maturity scores and an Indian-specific formula for third molar development.
- To assess age estimation accuracy using orthopantomograms.
Main Methods:
- Dental panoramic tomograms from 30 subjects (known age and sex) were analyzed.
- Age calculations were performed using Demirjian's and an Indian formula.
- Statistical analysis included Chi-square and ANOVA tests.
Main Results:
- Both formulas resulted in age underestimation.
- The Indian formula demonstrated a lower mean absolute error.
- Females achieved dental maturity earlier than males.
Conclusions:
- Population-specific formulas are recommended for improved accuracy.
- Ethnic and environmental variations should be considered in age estimation.
- Regression analysis can aid in developing precise, localized formulas.
