摘要


本報告觀察一顆外傷脫落之未成熟上顎門牙,在再植入後發生根管感染,經過根管清創、沖洗及根管內長期置藥之後,因再度之外傷而拔除,其間之一連串臨床及X光變化。希望藉由檢討該病例失敗的可能原因,尋求在遇到相似的病例時能不重蹈覆轍。

並列摘要


An infected replanted immature maxillary central incisor with sinus tract in a 7-year-old patient was treated. This clinical report illustrates how an infected immature replanted incisor that underwent conventional root canal therapy still progressed into a radicular cyst formation. After long-term Ca(OH)2 dressing, the tooth was extracted due to traumatic injury. Clinical and radiographic data were collected. The authors inspect the reasons of failure and hope to seek for better treatment methods for similar cases.
