| 摘 要： | 目的:比较不同根管预备器械对根管充填后冠方微渗漏的影响。方法:选择60个单根管前磨牙(弯曲度为10～20°)随机分为6组,分别以不锈钢K锉、VDW K锉、手动Protaper、机用Protaper、Hero642、Mtwo预备根管。采用冷侧压法进行根管充填,染色法比较不同根管预备器械对根管冠方封闭性能的影响。结果:不同根管预备器械对充填后根管冠方微渗漏影响不同,其中Hero 642预备组、Protaper预备组、VDWK锉组冠渗漏长度少于不锈钢K锉组,且差异有统计学意义(P<0.05),Hero 642预备组产生的冠方微渗漏最小。结论:不同根管预备器械预备根管后对冠渗漏影响不同,镍钛旋转器械预备根管后产生的冠方微渗漏较小,不锈钢K锉根管预备后产生的冠方微渗漏较大。 |

| Abstract: | AIM: To compare the effects of different root canal preparation instruments on coronal microleakage after root canal filling.METHODS: A total of 60 radix bicuspid teeth were chosen and were randomly divided in six groups.The teeth were respectively prepared with stainless steel K-files(group K),VDW K-files(group VK),hand use Protaper(group HP),machine use Protaper(group P),Hero 642(group H) and Mtwo(group M).Each tooth was filled with Cold manometric method and coronal microleakage was determined by color staining method.RESULTS: Group H,group VK,group HP and group P showed less leakage than group K(P<0.05).Group H produced the smallest coronal microleakage.CONCLUSION: Root canal preparation instruments showed influence on coronal microleakage.Nickel-titanium rotary instruments produced the least coronal leakage than other groups,stainless steel root canal instrument produced the most significant coronal leakage among the six groups. |
