Anterior arch crowding - a possible predictor of mandibular third molar impaction

Introduction: The role of the lower third molars in the lower incisors crowding has been debated for more than a century. Significant disagreement exists among practitioners, including both orthodontists and oral and maxillofacial surgeons whether the third molar causes mandibular anterior crowding. Aim of study: The purpose of this study is to ascertain whether the lower third molars can contribute to the occurrence or aggravation of crowding. Materials and methods: A sample of 131voluneteer (67 males and 64 females) aged 18-25 years were included in the 1st ,2nd, ,3rd ,4th and 5th stage of college of dentistry /Tikrit University was chosen, the sample was divided into three main groups consisted subjects who had mandibular third molars that were either impacted, erupted into function or agenesis. Results: The study showed that 70(53.4%) volunteer s out of the 131 have impacted lower 3rd molar, 52(39.7%) volunteers have erupted lower 3rd molar, while 9(7.6%) volunteer have agenesis of the 3rd molar. Conclusion: The crowded group revealed a higher percentage of impacted third molar while lowest percentage of third molar agenesis.
