Abstract

Objectives:
1) To determine the correlation between chronological age (CA) and mandibular third-molar development in sample of Khyber Pukhtunkhwa (KP) population
2) To derive regression formulae specific to this population to estimate age using third-molar calcification stages
3) To provide forensic reference data for age determination from third-molar mineralisation
Materials/Methods: Four hundred and seventy orthopantomographs (OPGs) of patients aged between 13-26 years from the Orthodontics department archive at the main tertiary dental hospital of KP were studied for development of mandibular third-molars staging using Demirjians method. Pearson Correlation test was applied to determine any relationship between CA and mandibular third-molars development. Independent t-test was performed to compare third-molar development in males and females. Population-specific formulae were derived using regression analysis.
Results: A strong positive correlation was found between CA and mandibular third-molar development (r 0.801; p-value
