Abstract
ABSTRACT This study investigated the diagnostic accuracy of cone beam computed tomography (CBCT) in determining the anatomical position of the impacted third molars in relation with the mandibular canal and the location of mental foramen. Materials and Methods: The prospective study included 50 patients (100 hemi mandibles) who presented with un erupted mandibular third molars, CBCT images obtained for all the patients using planmeca promax 3D mid proface unit. All types of impacted third molars (mesioangular, vertical, distoangular and horizontal) were included in this study. Results: Out of 100 hemi mandibles evaluated, 23% of cases mandibular nerve was seen buccal to the third molars, 25% was seen lingual to the third molars, 52% was seen inferior to the third molars. Mental foramen location identified in 14% at the 1st premolar region, in 40% of the mental foramen was identified at the 2nd premolar region and 46% of the mental foramen was identified in between the first and second premolars. Conclusion: CBCT imaging is an effective volumetric diagnostic imaging technology that produces accurate submillimeter resolution images of diagnostic quality. Hence CBCT evaluation is essential in the relationship of mandibular impacted 3rd molars to the mandibular canal and location of mental foramen during minor surgical procedures.
