中文摘要 | 源自乳牙之根尖囊腫是一種罕見的疾病。由於鄰近周圍發育中之恆牙,常常導致臨床診斷與治療上之困難。本文敘述一位七歲半之小女孩於接受左上第一乳臼齒之根管治療後發展出根尖囊腫之案例。此囊腫不但造成病患之腫脹與疼痛,更導致恆牙小臼齒牙胚之病理性位移。病患於接受囊腫剜出術並保留乳牙後,骨頭癒合良好;受推移之恆牙牙胚亦回復原位。此案例顯示乳牙牙髓治療為造成根尖囊腫之可能促成因子;因此牙髓治療後之乳牙應接受定期追蹤。此外,為避免傷及恆牙牙胚並協助之後順利換牙,混合齒列期之乳牙根尖囊腫處理應考慮保守性之手術治療。 |
英文摘要 | Radicular cysts arising from primary teeth have been considered rare. Due to proximity to developing permanent tooth germs, the clinical diagnosis and managements of these cystic lesions at mixed dentition stage can be challenging. In this article, we presented a case of radicular cyst originated from left maxillary first primary molar after its root canal therapy in a 7.5-year-old girl. The cyst caused not only alveolar swelling and pain but also displacement of developing tooth germs of underlying permanent bicuspids. Following a complete cyst enucleation with preservation of the primary tooth, uneventful bone healing was achieved, and spontaneous re-alignment of displaced tooth germs observed. This case suggested that pulp therapy of a primary tooth could be a potential contributing factor for the development of a radicular cyst, indicating the importance and necessity of periodic follow-up for primary teeth following pulp therapy. Furthermore, a conservative surgical treatment for cyst removal at mixed dentition stage should be considered to avoid potential damages to developing tooth germs and to assure a smooth transition to permanent dentition. |
