“ Kissing molars (KMs)” is a rare condition in which the root apices of two impacted molars face opposite directions so that the occlusal surfaces come into contact and the crowns are located within a single follicle.
We encountered a 29-year-old man in whom panoramic radiographs and computed tomography scans revealed impaction of the left mandibular third and fourth molars. The occlusal surfaces of the impacted molars were in contact with each other with the root apices facing opposite directions, and clearly delineated, unilocular, round and cystic permeation was observable surrounding the same crown. KMs are classified from Class I toⅢ at the site of impaction. In our patient, the third molar and the fourth molar (supernumerary tooth) were classified as Class Ⅲ. Tooth extraction and extirpation were performed with the patient under general anesthesia and the histopathological finding was a dentigerous cyst. The postoperative course has been good with no recurrence of the lesion for 18 months.
