磨牙根管治疗中不同器械对治疗效果的影响研究

Study on the effect of different instruments in root canal treatment of molar teeth

目的研究不同器械在磨牙根管治疗中对治疗效果的影响,为临床实践提供参考。方法选择进行磨牙根管治疗的70例患者作为研究对象,随机分配到不同的器械组,包括K锉组(23例)、尖细针组(23例)和超声器组(24例)。比较三组患者的根管清理度、根管充填质量、治疗时间。结果(1)K锉组的根管清理度(90.4±1.5)%高于尖细针组的(80.3±2.0)%及超声器组的(85.5±1.5)%,超声器组的根管清理度高于尖细针组,差异具有统计学意义(P<0.05)。(2)尖细针组的根管充填质量评分(9.1±0.4)分高于K锉组的(8.5±1.2)分及超声器组的(8.0±1.5)分,差异具有统计学意义(P<0.05);K锉组与超声器组的根管充填质量评分比较,差异无统计学意义(P>0.05)。(3)超声器组的治疗时间(25.2±1.8)min短于K锉组的(30.0±2.2)min及尖细针组的(35.4±2.5)min,K锉组的治疗时间短于尖细针组,差异具有统计学意义(P<0.05)。结论不同器械在磨牙根管治疗中有着不同的作用,在治疗中需要根据具体情况来选择对应的器械。

Objective To study the effect of different instruments in root canal treatment of molar teeth,so as to provide reference for clinical practice.Methods 70 patients who underwent root canal treatment of molar teeth were selected as study subjects,and were randomly assigned to different instrument groups,including the K-file group(23 cases),the fine-needle group(23 cases),and the ultrasound group(24 cases).The degree of root canal cleaning,root canal filling quality and treatment time of the three groups were compared.Results a.The degree of root canal cleaning of K-file group was(90.4±1.5)%,which was higher than(80.3±2.0)%of fine-needle group and(85.5±1.5)%of ultrasound group;the degree of root canal cleaning in ultrasound group was higher than that in fine-needle group;the difference was statistically significant(P<0.05).b.The score of root canal filling quality in fine-needle group was(9.1±0.4)points,which was higher than(8.5±1.2)points in K-file group and(8.0±1.5)points in ultrasound group,and the difference was statistically significant(P<0.05).There was no significant difference in score of root canal filling quality between K-file group and ultrasound group(P>0.05).c.The treatment time of(25.2±1.8)min in ultrasound group was shorter than(30.0±2.2)min in K-file group and(35.4±2.5)min in fine-needle group;the treatment time in K-file group was shorter than that in fine-needle group;the difference was statistically significant(P<0.05).Conclusion Different instruments have different functions in root canal treatment of molar teeth.In the treatment,the corresponding instruments should be selected according to the specific situation.
