摘要
ABSTRACT Cemental tear (CeT) is a rare clinical finding characterized by a partial or complete detachment of a portion of the cementum from the root surface. CeT is a well‐documented condition in the adult population, particularly among older individuals with periodontal disease, occlusal stress, or traumatic dental injuries (TDI). The prevalence of CeT in adults ranges from 0.9% to 2%. However, CeT has not been previously reported in the pediatric population. Approximately, one in three children experiences TDI, which subjects the teeth to a magnitude of force that can lead to cemental separation in both mature and immature anterior teeth. The clinical and radiographic features of CeT overlap with those of endodontic‐periodontal lesions. Hence, it is assumed that CeT is seldom encountered in children, leading to missed or delayed diagnosis and treatment. This case series provides reports of a 13‐year‐old male and a 10‐year‐old female with CeT following TDI affecting maxillary central incisors. The clinical examination showed signs of TDI, while radiographs demonstrated a detached cemental fragment without pulpal involvement. The location of the finding warranted conservative management. This report reviews incidence, clinico‐radiographic diagnosis, and management of CeT. This report also provides a novel radiographic classification of CeT secondary to TDI for early diagnosis and treatment to prevent sequelae and maintain long‐term tooth function.
