Root perforation is a common endodontic accident. Its management depends mainly on root canal disinfection and sealing the perforation area by preventing any communication with the periodontium to prevent recontamination. A patient was referred to treat root perforation due to a previous treatment of tooth #22. The diagnosis was symptomatic periapical periodontitis, and the treatment plan was to retreat the root canal of #22 and make a surgical intervention (apicoectomy) associated with antimicrobial photodynamic therapy as a complementary technique. Five mineral oxides (5MO) cement was used as a root-end filling material. The procedures were performed in two sessions and controlled in two visits (after 30 days and 12 months). A bone neoformation was observed at the periapical area of tooth #22. 5MO bioceramic cement was effective in inducing the repair of the periapical lesion and had the ability to seal the exposed periapical area of the tooth. Its success depended mainly on root canal and surgical site disinfection.
根管穿孔是一种常见的牙髓病治疗意外情况。其处理主要依赖于根管消毒，并通过防止与牙周组织相通来封闭穿孔区域，以防止再次污染。一名患者因之前对22号牙的治疗而前来治疗根管穿孔。诊断为有症状的根尖周炎，治疗方案是对22号牙的根管进行再治疗，并进行外科干预（根尖切除术），同时采用抗菌光动力疗法作为辅助技术。使用了五种金属氧化物（5MO）水泥作为根尖充填材料。治疗分两个阶段进行，并在两次复诊时（30天后和12个月后）进行检查。在22号牙的根尖区域观察到了骨新生。5MO生物陶瓷水泥在诱导根尖病变修复方面有效，并且有能力封闭牙齿暴露的根尖区域。其成功主要取决于根管和手术部位的消毒。
