The role of mandibular 3rd Molars on the incidence of Condylar Fractures – a clinical study

Aims: Condylar region of the mandible is the most vulnerable site to fracture due to its anatomical weakness. It has been noted that mandibular third molars may reduce the occurrence of condylar fractures. This study was conducted to verify this hypothesis. Materials and methods: This retrospective study of records of 147 mandibular fracture patients treated during 5 year period during 2008 to 2013 were analyzed for the correlation between 3 rd molars and incidence of condyle fractures. Results: Condylar fracture was two times greater in those with missing or completely erupted mandibular third molars as compared to those with unerupted ones (p<0.001), erupted mandibular third molar position can influence the occurrence of condylar fracture. Conclusion:erupted mandibular third molars significantly increased the occurrence of condylar fractures.
