A case of true concrescence diagnosed with cone-beam CT and in vivo micro-CT

摘要

A 33-year-old woman visited our hospital complaining of pain in the left maxillary second molar. The second molar was submerged, and the third molar was impacted. Cone-beam computed tomography images showed that the roots of the second and third molars were very close to each other. Under local anesthesia, the concrescent teeth were extracted en bloc. The histopathological diagnosis was concrescence of the teeth. Micro-computed tomography images also showed that the teeth were fused by the cementum only, without involvement of the dentin.
