报道1例上前牙根尖囊肿术后根面暴露的多学科联合治疗病例,旨在为此类病例提供临床经验。该病例主要存在前牙囊肿术后唇侧牙根暴露、牙冠变色等问题,口腔医师为其制订了个性化的牙体牙髓、牙周等多学科联合治疗方案。治疗后患者的根尖区感染得到控制,暴露的牙根面得到了软组织的覆盖,且经过内漂白后前牙美观也得到了较大的改善,取得了良好且患者满意的结果。临床上,对于大范围颌骨手术术后存在软硬组织缺损较大的病例,在尽量控制炎症的基础上,需要考虑软组织缺损修复问题。

This article reports a case of multidisciplinary combined treatment for root exposure after cyst surgery, aiming to provide clinical experience for such cases. The case mainly presented with problems such as root exposure on the labial side and tooth discoloration after anterior tooth cyst surgery. A personalized multidisciplinary combined treatment plan was developed for the teeth and periodontium. After treatment, the infection in the apical area was controlled. The exposed root surface was covered by soft tissue, and the anterior teeth aesthetics were significantly improved after internal bleaching, achieving good and satisfactory results for the patient. Clinically, for cases with large soft and hard tissue defects after extensive jaw surgery, the issue of soft tissue defect repair needs to be considered on the basis of controlling inflammation as much as possible.
