Root canal disinfection is considered critical for achieving successful regenerative endodontic procedures. Photo-activated disinfection is a novel disinfection method that can help to achieve the goal of regenerative endodontics. This article reports the clinical and radiographic results after single visit regenerative endodontics using photo-activated disinfection. An 8.5-year-old girl complained of fractured upper right central incisor. Pulp necrosis was diagnosed on the basis of clinical findings. The root canal was irrigated with sodium hypochlorite solution (1.5%) followed by saline. Then, the canal was dried with paper points. A combination of a photosensitizer solution and low power laser light were applied. EDTA solution was used as a final irrigant. Bleeding was induced, followed by placement of collagen resorbable matrix and white mineral trioxide aggregate. Two days later, the tooth was sealed and restored with permanent filling. Clinical findings revealed no pain on percussion or palpation tests. Radiographic examination revealed an increase in root length, an increase of apical root thickness and apical closure at the 12-month follow-up period. Regenerative endodontics using photo-activated disinfection achieved successful outcomes in the necrotic immature permanent tooth.
根管消毒被认为是实现成功的再生性牙髓治疗的关键。光激活消毒是一种新型消毒方法，有助于实现再生性牙髓治疗的目标。本文报告了使用光激活消毒进行单次就诊再生性牙髓治疗后的临床和影像学结果。一名8岁半的女孩主诉右上中切牙折断。根据临床检查结果诊断为牙髓坏死。用次氯酸钠溶液（1.5%）冲洗根管，随后用生理盐水冲洗。然后，用纸尖吸干根管。应用光敏剂溶液和低功率激光的组合。使用乙二胺四乙酸（EDTA）溶液作为最终冲洗剂。诱导出血，随后放置可吸收胶原基质和白色矿物三氧化物凝聚体。两天后，牙齿进行密封并用永久性充填材料修复。临床检查结果显示叩诊或触诊试验无疼痛。影像学检查显示在12个月的随访期内牙根长度增加、根尖牙根厚度增加以及根尖闭合。使用光激活消毒的再生性牙髓治疗在坏死的未成熟恒牙中取得了成功的结果。
