“…There is high risk of lingual nerve damage using lingual split technique or elevating third molar flap medially to the distoangular recess [23]. Rood and Shehab [24] showed on panoramic radiographs that in most cases the roots of third molars are in close proximity to the mandibular canal. Furthermore, in some cases third molar roots can contact or penetrate into mandibular canal or they can be deflected.…”

“…This fact inspirited further studies for the predictive radiographic parameters identification. Rood and Shehab [24] distinguished four radiographic indicators observed in the tooth root (darkening, deflection and narrowing of the root, and a bifid root apex), and the other three in the canal (diversion, narrowing, and interruption in the white line of the canal). Studies demonstrated that the most important parameters for inferior alveolar nerve injury prediction are third molar root apices inside or in contact with the mandibular canal [46,67-69].…”

“…In contrast, some previous classifications recommended assessing too many radiological parameters determining wisdom tooth roots relationship with mandibular canal. For example, Rood and Shehab [24] distinguished four radiographic indicators observed in the tooth root (darkening, deflection and narrowing of the root, and a bifid root apex), and the other three in the canal (diversion, narrowing, and interruption in the white line of the canal). Latest clinical studies demonstrated that the most important parameters for inferior alveolar nerve injury prediction are third molar root apices inside or in contact with the inferior alveolar canal [46,67-69] and absence of cortication around the inferior alveolar canal [70-72], this is why mentioned above parameters were included into inferior alveolar nerve injury risk evaluation assessment.…”

ObjectivesThe purpose of present article was to review impacted mandibular third molar aetiology, clinical anatomy, radiologic examination, surgical treatment and possible complications, as well as to create new mandibular third molar impaction and extraction difficulty degree classification based on anatomical and radiologic findings and literature review results.Material and MethodsLiterature was selected through a search of PubMed, Embase and Cochrane electronic databases. The keywords used for search were mandibular third molar, impacted mandibular third molar, inferior alveolar nerve injury third molar, lingual nerve injury third molar. The search was restricted to English language articles, published from 1976 to April 2013. Additionally, a manual search in the major anatomy and oral surgery journals and books was performed. The publications there selected by including clinical and human anatomy studies.ResultsIn total 75 literature sources were obtained and reviewed. Impacted mandibular third molar aetiology, clinical anatomy, radiographic examination, surgical extraction of and possible complications, classifications and risk factors were discussed. New mandibular third molar impaction and extraction difficulty degree classification based on anatomical and radiologic findings and literature review results was proposed.ConclusionsThe classification proposed here based on anatomical and radiological impacted mandibular third molar features is promising to be a helpful tool for impacted tooth assessment as well as for planning for surgical operation. Further clinical studies should be conducted for new classification validation and reliability evaluation.

“…Third molar surgery related to inferior alveolar nerve injury is reported to occur in up to 3.6% cases permanently and 8% cases temporarily. 2,3 Factors associated with inferior alveolar nerve injury (IANI) are age, difficulty of surgery and proximity to the IAN canal. If the tooth is closely associated with the IAN canal radiographically, 20% of patients having these teeth removed are at risk of developing temporary IAN nerve injury and 1-4% are at risk of permanent injury.…”
