Summary
Dental attrition in molars can estimate adult age. Maxillary teeth, particularly first and second molars, offer more accurate age estimation than mandibular teeth.
Area of Science:
- Forensic Anthropology
- Dental Age Estimation
Background:
- Dental attrition of permanent molars is a recognized method for estimating adult age.
- This study aimed to refine age estimation using molar attrition patterns.
Purpose of the Study:
- To evaluate the accuracy of age estimation based on the average attrition stage of permanent first and second molars.
- To compare the efficacy of maxillary versus mandibular molars for age determination.
Main Methods:
- Examined 451 Nepalese individuals over 20 years old with intact maxillary and mandibular molars.
- Calculated average molar attrition and applied regression analysis for age estimation equations.
Main Results:
- A strong positive correlation was found between age and molar attrition.
- Maxillary molars provided more accurate age estimations (mean difference: 3.82 years) compared to mandibular molars (mean difference: 5.17 years).
- Multivariable regression analysis improved age estimation accuracy.
Conclusions:
- Maxillary first and second permanent molars are superior for dental age estimation.
- Utilizing both maxillary molars enhances the accuracy of age determination.
