目的:探讨手术显微镜在牙隐裂诊断和治疗中的应用,并对综合治疗方案的临床效果进行评价。方法:采用手术显微镜和染色法相结合,对113个隐裂牙进行诊断,并根据症状和裂纹深度对隐裂牙进行分类,其中47个属早期隐裂牙,患牙经调后在显微镜下磨除隐裂裂隙,光固化复合树脂充填。66个晚期隐裂牙,经根管治疗后全冠修复。所有病例均经1年随访观察。结果:47个早期隐裂牙,经预防性充填治疗后临床症状缓解32个牙,成功率68.09%;66个晚期隐裂牙,经综合治疗随访1年后,治疗成功率93.85%,5个患牙因症状加重而拔除。结论:手术显微镜的应用可提高对隐裂牙的诊断率及治疗成功率,对隐裂牙进行合理的临床分类并采取相应的处理措施能最大限度地保存患牙的咀嚼功能。
Objective: To explore the application of surgical microscope in the diagnosis and treatment of occlusion of the tooth, and to evaluate the clinical effect of the comprehensive treatment plan. Methods: A total of 113 fractured teeth were diagnosed by surgical microscope and staining method. According to the symptoms and the depth of the fractures, the occult teeth were classified, of which 47 were early cryptocysis. The affected teeth were examined under the microscope Abrasion cracking crack, light curing composite resin filling. 66 late cracked teeth, the whole crown after root canal repair. All cases were followed up for 1 year. Results: Forty-seven cases of early-cracked teeth were treated with prophylactic filling. The clinical symptoms were relieved of 32 teeth with a success rate of 68.09%. Sixty-six patients with advanced cryptus were followed up for one year after treatment. The success rates were 93.85% and 5 Teeth suffering from exacerbations and removal. Conclusion: The application of surgical microscope can improve the diagnosis rate and treatment success rate of cracked tooth. Reasonable clinical classification of cracked tooth and corresponding treatment measures can save maximally the chewing function of affected tooth.
