Hypercementosis is a non-neoplastic condition in which excessive cementum is deposited in continuation with the normal radicular cementum. Apart from the idiopathic nature of hypercementosis, this condition is associated with several local and systemic factors. Cementoblastoma is an odontogenic tumour characterized by the proliferation of functional cementoblasts that form a large mass of cementum or cementum-like tissue on the tooth root. Although hypercementosis and cementoblastoma are typical conditions with distinct clinical evolution, atypical cases may challenge their diagnosis. Because cementoblastoma is a neoplasm with unlimited growth potential, the usual treatment is complete surgical resection, whilst conservative treatment is recommended for hypercementosis. An atypical case of hypercementosis with similarities to cementoblastoma is reported and its differential diagnosis is discussed.
牙骨质增生是一种非肿瘤性疾病，其中过多的牙骨质与正常的牙根牙骨质连续沉积。除了牙骨质增生的特发性本质外，这种情况还与多种局部和全身因素有关。成牙骨质细胞瘤是一种牙源性肿瘤，其特征是功能性成牙骨质细胞增殖，在牙根上形成大量牙骨质或类牙骨质组织。尽管牙骨质增生和成牙骨质细胞瘤是具有不同临床发展过程的典型病症，但非典型病例可能会对它们的诊断提出挑战。由于成牙骨质细胞瘤是一种具有无限生长潜能的肿瘤，通常的治疗方法是完整的手术切除，而牙骨质增生则建议采用保守治疗。本文报告了一例与成牙骨质细胞瘤相似的非典型牙骨质增生病例，并讨论了其鉴别诊断。
