隧道式充填法的临床评价

目的 评价隧道式充填法的临床效果。方法 选取邻面龋坏所致的牙髓炎或根尖周炎患牙35颗，常规牙髓治疗后进行隧道式充填，跟踪随访2年。结果 1a后35例患者的35颗牙进行临床复查，成功率为100％；2a后，2例2颗牙失访，33例患者的33颗牙进行临床复查，成功率仍为100％。结论 隧道式充填法保留了患牙的邻面接触点和边缘嵴，对于恢复牙齿的邻接关系，提高患牙抗折力有重要意义，临床效果好。

Clinical Evaluation of Tunnel-Restoration

Objective To evaluate the clinical effect of tunnel-restoration.Methods35teeth with pulpitis or periapical periodontitis caused by interproximal caries were selected.Tunnel-restoration was used after endodontic treatment.Clinical examinations were taken to follow up all the teeth at one year and two years respectively after treatment.Results At one year after treatment,35cases were followed up,the rate of success was100%.At two years after treatment,33cases were followed up and2cases were lost,the rate of success was also100%.Conclusions Proximal contact point and marginal ridge of the teeth were preserved by using tunnel-restoration,which is very important to restore proximal contact,enhance the ability of resistance to fracture,and has good clinical effect.
