A Study on Eruption of Third Molar of Libyan Individual and its Comparison with the Egyptian

The aim of the present investigation was to reconstruct the chronological age bases on third molar eruption and to compare between Libyan and Egyptian. A total of 200 cases both Libyan (100) and Egyptian (100) were assembled from the school and university of Libya between 15 and 25 years of age. A strong agreement was found between eruptions time of third molar and chronological age. The statistical analysis revealed that earliest third molar eruption was in the female at 16 year which has completed at 24 years in both the sexes. It also erupted earlier in lower jaw in both the sexes. The spaces for third molar also appear earliest in female at 15 year of age with early preponderance in lower jaw. This study has shown no differences in eruption between Libyan and Egyptian.
