- Abstract
A cemental tear (CeT) is a definitive clinical entity and its radiographic appearance is well known in single‐rooted teeth. However, the imaging features of CeT in multi‐rooted teeth have not been clarified. We report a case of CeT which arose in the maxillary first molar and exhibited an unusual appearance in cone‐beam computed tomography images. The torn structure was verified as cementum by micro‐computed tomography and histological analysis. The hypercementosis, most likely induced by occlusal force, might have been torn from the root by a stronger occlusal force caused by the mandibular implant. An unusual bridging structure was created between the two buccal roots. These features may occur in multi‐rooted teeth with long‐standing deep pockets and abscesses that are resistant to treatment.
