中文摘要 | 本報告係針對1998至1996年在臺灣省立桃園醫院牙科門診部82位具前顎贅生齒 (premaxillary supernumerary teeth)病患之125顆贅生齒,由病曆記載及X光片記錄作回 溯性分析。主要觀察在各個齒列發育期所發生之併發症。我們發現92%的前顎贅生齒未萌發 (unerupted),而24.4%引起旁邊門齒延遲萌發(delayed eruption),31.7%的案例引起旁 邊門齒之移位(displacement)。與贅生齒有關之病理變化少見, 但仍有6%之案例引發含 齒囊腫(dentigerous cyst),3.7%的案例造成鄰近牙齒失活(loss of vitality)。所有的 病理變化均發生在�琱�齒列期。因此,在�琱�齒列期之前,對此情況之早期診斷與治療,可 以避免病理變化的發生及較大型的手術治療。 |
英文摘要 | The clinical records and radiographs of 82 patients with 125 premaxillary supernumerary teeth, taken during the period from 1988 through 1996, were studied. The complications associated with premaxillary supernumerary teeth at various stages of dentition were analyzed. From the clinical and radiographic examinations, we found that 92% of the premaxillary supernumerary teeth were unerupted. Delayed eruption and displacement of the adjacent permanent incisors occurred in 24.4% and 31.7% of the cases respectively. Associated pathological changes were rare, however, the formation of dentigerous cysts was found in 6%, and loss of vitality of the adjacent teeth was found in 3.7% of the cases. The associated pathological changes were all found in the permanent dentition stage, suggesting that diagnosis and treatment for the condition should be made prior to the stage of permanent dentition to minimize the necessity for extensive intervention. |
