MORPHOLOGICAL VARIATIONS OF THREE-ROOTED MANDIBULAR MOLARS IN ANCIENT ANATOLIAN POPULATIONS (DILKAYA MOUND, VAN, TURKEY): A LITERATURE REVIEW ON WORLD POPULATIONS

This study reports the first recorded discovery of three-rooted mandibular molars (3RM) from a Middle Age archaeological population unearthed in Van, Eastern Anatolia. A historical context is given for the research site, Dilkaya Mound, which has a history of approximately 2500 years. In total 462 permanent first and second teeth, 219 deciduous teeth, and a total of 682 mandibular teeth belonging to 358 individuals from Early Iron Age and Middle Age populations were included in this study. The earliest recorded population on site which dates to the Early Iron Age shows no sign of 3RM1 and 3RM2. The 3RM1 feature first appears in Anatolia at a rate of 1,05% by the Middle Age. The frequency of 3RM2 was found at a rate of 0,67%, and 3RM3 at a rate of 2,44 % in the population. Three rooted deciduous lower first molar teeth (3rm1) were observed at a rate of 2,44%; a new feature in the literature. The results of our study support the existing explanation that genetic drift plays a significant role in the distribution of 3RM via the wave of migration to the west from Asia during the Middle Age
