摘要: 目的 探讨根管负压冲洗与传统注射器根管冲洗的有效性以及根管负压冲洗作为根管冲洗方式的可行性。方法 采用人工硅橡胶牙槽窝模型,模拟根尖周围组织对冲洗液的阻力,比较根管负压冲洗系统与传统注射器进行根管冲洗对根尖孔推出物的影响。在离体牙模型上,比较2种冲洗方式对根管内粪肠球菌(Enterococcus faecalis,E. faecalis)的清除作用。采用SPSS 17.0软件包对数据进行统计学分析。结果 与传统注射器相比,根管负压冲洗系统根尖孔推出物的量显著减少(P<0.05),对E. faecalis的清除作用也显著增强(P<0.05)。结论 根管负压冲洗可作为一种相对有效的根管冲洗方式。

Abstract: PURPOSE: To compare the efficiency of negative pressure irrigation and conventional syringe irrigation and evaluate the possibility as a new way of irrigation. METHODS: In vitro silicone socket model was used to simulate the resistance of apical flow by apical surrounding tissues. The in vitro efficacy on apical extrusion and E.faecalis elimination between negative pressure irrigation and conventional syringe irrigation was compared. SPSS 17.0 software package was used for statistical analysis. RESULTS: Negative pressure irrigation extruded less (P<0.05), and was more effective in E.faecalis elimination(P<0.05) than conventional syringe. CONCLUSIONS: Negative pressure irrigation is a promising irrigation technique during root canal therapy.

Key words: Apical negative pressure irrigation, Conventional syringe irrigation, Apical extrusion, E.faecalis
