目的:总结热牙胶连续波充填技术的充填质量及临床效果。方法:成人牙髓病及根尖周病30例,常规根管预备,使用热牙胶充填根管,并在治疗后3~6个月进行回访,观察临床疗效。结果:30例中,根充恰填率90%,根管充填后未发生疼痛。X线片显示根充严密合适,咬合关系良好,根尖瘘道2~3周愈合。术后3个月和6个月复查,X线片显示根尖周透射区缩小,骨质密度增加。结论:热牙胶连续波充填技术安全、可靠,操作简便,近期观察临床效果好。
OBJECTIVE: To summarize the filling quality and clinical effect of hot-dentin continuous wave filling technique. Methods: 30 cases of adult pulp endodontic and periapical disease were treated with conventional root canal preparation. The root canal was filled with hot dentin, and the wounds were followed up 3 to 6 months after treatment. The clinical effect was observed. Results: In the 30 cases, the filling rate of root filling was 90%, no pain occurred after root canal filling. X-ray shows the root filling tight fit, good occlusion, apical fistula healed 2 to 3 weeks. Three months and six months after surgery, X-ray films showed that the periapical zone of transmissivity was reduced and bone density increased. CONCLUSION: The technique of hot glue continuous wave filling is safe, reliable and easy to operate. It has been observed recently that clinical effect is good.
