The success rate of conservative endodontic management for root fracture varies greatly based on different methods used. It has been rarely reported that calcium silicate-based materials are applied in root fracture treatment.
A 38-year-old male patient presented with spontaneous pain from the upper left anterior teeth for 1 wk. The spontaneous pain was subsequently relieved, but pain on mastication persisted for 3 d. The patient had a dental trauma from a boxing match 15 years ago. Cone beam computed tomography showed that the maxillary left central incisor had oblique fracture lines and a radiolucent lesion around the fracture line. The tooth was diagnosed with an oblique root fracture with no healing and symptomatic apical periodontitis. In the following conservative endodontic management, the coronal and apical fragments of the canal both were chemo-mechanically prepared and obturated using a single cone gutta-percha with iRoot SP (Innovative BioCreamix Inc, Vancouver, Canada), a new calcium silicate-based bioceramic root canal sealer. At follow-ups at 1, 6, 12, and 24 mo, the patient was asymptomatic and the radiolucency around the fracture line was healing radiographically.
Conservative root canal treatment is an alternative treatment in some cases of oblique root fracture with no healing. The application of bioceramic sealers and single core obturation techniques may also be essential to obtain an excellent outcome.
基于所使用的不同方法,根管治疗术保守治疗牙根折裂的成功率差异很大。很少有报道将硅酸钙基材料应用于牙根折裂的治疗。
一名38岁男性患者,左上前牙自发痛1周。自发痛随后缓解,但咀嚼痛持续3天。该患者15年前因拳击比赛导致牙外伤。锥形束计算机断层扫描显示上颌左中切牙有斜行骨折线,骨折线周围有透射区。该牙被诊断为斜行牙根折裂且未愈合,伴有症状性根尖周炎。在接下来的根管治疗术保守治疗中,根管的冠方和根尖方断端均进行了化学机械预备,并使用iRoot SP(加拿大温哥华Innovative BioCreamix公司)进行单根牙胶尖充填,iRoot SP是一种新型的硅酸钙基生物陶瓷根管封闭剂。在1、6、12和24个月的随访中,患者无症状,骨折线周围的透射区在影像学上正在愈合。
在一些未愈合的斜行牙根折裂病例中,根管治疗术保守治疗是一种替代治疗方法。生物陶瓷封闭剂和单根充填技术的应用对于获得良好的治疗效果可能也至关重要。
