Odontomas are tumours of odontogenic origin. In these tumours both the epithelial and mesenchymal cells undergo differentiation to form enamel and dentin with variable amounts of cementum and pulp tissue. The odontomas represent a hamartoma rather than a neoplasm. When the enamel and dentin are laid down in an organized manner it is termed as a compound odontoma wherein the tumour forms a collection of small structures resembling teeth. On the other hand, an irregular mass with no similarity to teeth is termed as a complex odontoma. There are cases of extensive and multiple compound odontomas which have been identified in either of the jaws. The present case is rare with multiple compound odontomas involving both the jaws of 45-year-old male patient. A review of seven such cases reported so far has been presented.
牙瘤是牙源性肿瘤。在这些肿瘤中,上皮细胞和间充质细胞都会发生分化,形成釉质和牙本质,并伴有数量不等的牙骨质和牙髓组织。牙瘤代表的是错构瘤而非肿瘤。当釉质和牙本质以有组织的方式沉积时,就被称为复合性牙瘤,其中肿瘤形成一系列类似牙齿的小结构。另一方面,与牙齿没有相似之处的不规则肿块则被称为复杂性牙瘤。在上下颌骨中均已发现广泛且多发的复合性牙瘤病例。本病例较为罕见,一名45岁男性患者的上下颌骨均出现了多发复合性牙瘤。本文还对迄今为止报道的7例此类病例进行了综述。
