Evaluation of the association between mandibular canal and mandibular third molars on cone beam computerized tomography (CBCT)

Background: The aim of this study was to introduce a new radiological classification that could be normally used in clinical practice assess the relationship between an impacted third molar and mandibular canal on cone beam CT (CBCT) images. 
 Material Methods: teeth canal, distance inferior alveolar buccal-apical-lingual position relative tooth, presence contact were evaluated according classification. According these criteria, total eight classifications two subtypes , class A B, made. CBCT images 50 patients independently studied all possible relationships IAN cross-sectional SPSS software version 24.0 for statistical analysis. Results: For lower left (38), it found most common 1A (48,6%) gender-free examination. (48) right mandibula, (45%) regardless gender. Conclusion: use valid support obtain language among operators order define
