Dental trauma results in various complications and poses an enigma to the practitioner. Calcific metamorphosis is one of the sequelae of trauma. A female patient of 35 years visited the specialty clinic of endodontics for the management of a discolored tooth. Clinically, discolored 21 was observed with no pain on palpation and percussion. The pulp sensibility test revealed a negative response. Radiographic examination revealed pulp canal obliteration with an apical radiolucency of Peri Apical Index (PAI 4). The tooth was diagnosed as necrotic pulp with asymptomatic apical periodontitis. Attempt to negotiate the canal under a Dental Operating Microscope (LABOMED, Los Angeles, CA, USA) and ultrasonics (Satelec, Acteon, France) was futile. Cone-beam computed tomography image revealed a patent canal in the apical third. Using real-time guided endodontics with a dynamic navigation system (Navident, ClaroNav, Toronto, ON, Canada), the protocol of plan, trace, and place was followed, and successful canal negotiation was achieved. After radiographic confirmation, root canal treatment was completed.
牙外伤会导致各种并发症,给从业者带来难题。钙化性变性是外伤的后遗症之一。一名35岁女性患者前往牙髓病专科诊所处理一颗变色牙。临床检查发现21号牙变色,触诊和叩诊均无疼痛。牙髓活力测试显示阴性反应。影像学检查显示牙髓腔闭塞,根尖周透射区,根尖周指数(PAI 4)。该牙被诊断为牙髓坏死伴无症状性根尖周炎。尝试在牙科手术显微镜(LABOMED,美国加利福尼亚州洛杉矶)和超声设备(Satelec,法国Acteon公司)下疏通根管未成功。锥形束计算机断层扫描图像显示根尖三分之一处根管通畅。使用动态导航系统(Navident,ClaroNav,加拿大多伦多)进行实时引导牙髓治疗,遵循计划、追踪和放置的方案,成功疏通了根管。经影像学确认后,完成了根管治疗。
