Odontoma is a comparatively common odontogenic tumor, and it may lead to interference with the eruption of its associated tooth. Odontomas are mostly associated with permanent teeth, and they are rarely associated with deciduous teeth. The purpose of this report is to analyze 107 odontomas and to present a case of complex odontoma associated with a lower deciduous second molar.
The 106 cases were analyzed with regard to the following parameters: age, gender, location, erupted teeth, congenital missing teeth, radiological features, histopathological features and prognosis.
Of the 106 cases, 41 were complex odontoma, 62 were compound odontoma, and three were immature odontoma. Compound odontoma had a predilection for the anterior. Complex odontoma occurred more often at the mandible.
Odontoma located above the tooth crown of lower deciduous molar did not behave clinically different from that associated with permanent tooth. An odontoma could be related with a supernumerary tooth or a missing tooth. If odontomas, which interfered with tooth eruption, were extirpated early, the impacted teeth would probably erupt normally and be normal in shape.
牙瘤是一种相对常见的牙源性肿瘤，可能会导致与其相关的牙齿萌出受阻。牙瘤大多与恒牙相关，很少与乳牙相关。本报告的目的是分析107例牙瘤，并呈现1例与下颌乳第二磨牙相关的复杂牙瘤病例。
对106例病例分析了以下参数：年龄、性别、位置、萌出牙齿、先天性缺牙、放射学特征、组织病理学特征和预后。
106例病例中，41例为复杂牙瘤，62例为组合性牙瘤，3例为未成熟牙瘤。组合性牙瘤好发于前部。复杂牙瘤多见于下颌骨。
位于下颌乳磨牙牙冠上方的牙瘤在临床上与恒牙相关牙瘤表现无异。牙瘤可能与多生牙或缺失牙有关。如果早期切除妨碍牙齿萌出的牙瘤，阻生牙可能会正常萌出且形态正常。
