目的:观察GuttaFlow充填系统充填根管的临床疗效。方法:将急、慢性根尖周炎或急、慢性牙髓炎患者的120个患牙,随机分成两组。根管预备后分别用氧化锌丁香油糊剂加牙胶尖的冷侧压法(对照组)或GuttaFlow充填技术加牙胶尖(实验组)进行根管充填。根充后即刻拍X线牙片评价根充效果,术后1周及半年评价其临床疗效。结果:两组病例根充后X线显示充填效果有统计学差异(P<0.05),随访半年的临床成功率无统计学差异(P>0.05)。结论:GuttaFlow充填系统是一种高效、简便的根管充填技术,但是远期疗效还有待于进一步观察。
Objective: To observe the clinical efficacy of filling GuttaFlow filling system. Methods: 120 patients with acute and chronic apical periodontitis or acute and chronic pulpitis were randomly divided into two groups. After root canal preparation, root canal filling was performed with cold side pressure method (control group) or GuttaFlow filling technique plus gutta percha (experimental group) with zinc oxide lilac oil paste plus gingivitis tip respectively. Immediately after root filling, X-ray was performed to evaluate the effect of root filling. The clinical efficacy was evaluated 1 week and 6 months after operation. Results: There was a significant difference in filling effect between two groups (P <0.05). There was no significant difference in clinical success rate between the two groups (P> 0.05). Conclusion: GuttaFlow filling system is an efficient and simple root canal filling technique, but the long-term efficacy remains to be further observed.
