The research aims to determine the relationship between the mandibular third molars and the nearby lingual cortical bone as well as to determine the frequency of lingual cortex perforation.The analysis was carried out by “CBCTs (cone beam computed tomographic scans)” of 18-65 years old patients. Lingual cortex fenestration at both root tips was observed. Almost three-quarters of radiographs showed the majority of the lingual area on the upper portion of a root (51.2% and 52.8%). The most lingual region and the area surrounding the root tip were both 1.25 mm thick. Mandibular third molars and perforated across both base levels were shown to be significantly related (P value.001). More than 50% of patients had lingual cortical perforation brought on by mandible third-molar teeth. The likelihood of lingual cortical rupture following extraction of the mandibular third molars is a sign of a prior problem rather than surgery.
