微波治疗对老年人后牙慢性根尖周炎一次性根充的临床效果

Clinical Effect of Microwave Therapy on the Disposable Root Canal Filling of Chronic Periapical Periodontitis of Molars of Senile Patients

目的探讨微波治疗对老年人后牙慢性根尖周炎一次性根充的临床效果。方法该院门诊2012—2017年方便选择患慢性根尖周炎的老年人座牙236例。年龄55～75岁,其中男性110例,女性126例。随机分为实验组与对照组。实验组在制备根管后选用符合根管长度的微波辐射探针插入根管内,功率调至35 W,每个根管照射4 s,然后选择碘仿氧化锌糊剂加牙胶尖加压充填,对照组在制备根管后直接碘仿氧化锌糊剂加牙胶尖加压充填。所有患者均由一人操作完成,两组患者均在48 h及24个月后复查。结果 48 h复诊,实验组122颗成功114颗,其中前磨牙46颗,磨牙68颗,成功率93.4%,对照组114颗成功94颗,其中前磨牙40颗,磨牙54颗,成功率82.4%(χ~2=8.998,P=0.003);24个月复诊,实验组122颗成功116颗,其中前磨牙47颗,磨牙69颗,成功率95.1%,对照组114颗成功96颗,其中前磨牙42颗,磨牙54颗,成功率64.2%,实验组的成功率明显优于对照组(χ~2=8.167,P=0.003,P<0.05)。结论微波消毒老年人后牙根管时一种较理想的方法。在老年人后牙一次性根充治疗中有良好的临床效果。

Objective To study the clinical effect of microwave therapy on the disposable root canal filling of chronic periapical periodontitis of molars of senile patients.Methods 236 cases of senile patients with chronic periapical periodontitis aged from 55 to 75 years old admitted and treated in our hospital from 2012 to 2017 were convenient selected,including 110 males and 126 females,and the patients were randomly divided into two groups,the experimental group selected the microwave radiation probe after the preparing the root canal,power transferred to 35 W,every root canal was radiated for 4 s,and then selected the iodoform zinc oxide paste and gutta-percha point for pressurized filling,while the control group directly used the iodoform zinc oxide paste and gutta-percha point for pressurized filling after preparing the root canal,all patients were finished by the operation,and both groups were reexamined in 48 h and 24 months.Results The patients returned visit in 48 h,114 teeth successes of 122 teeth in the experimental group,including 46 premolar teeth,68 molarsin experimental group,and the success rate was 93.4%,in the control group,94 teeth succeed of 114 teeth in the control group,including 40 premolar teeth and 54 molars,and the success rate was 82.4%(χ^2=8.998,P=0.003),and the patients returned visit in 24 months,in experimental group 116 teeth succeed of 122 teeth,including 47 premolar teeth and 69 molars,and the success rate was 95.1%,control group 96 teeth succeed in 114 teeth in the control group,including 42 premolar teeth and 54 molars,and the success rate was 64.2%,and the success rate in the experimental group was obviously better than that in the control group(χ^2=8.167,P=0.003,P<0.05).Conclusion The microwave disinfection of posterior root canal of senile patients is an ideal method,and it has a good clinical effect in treatment of the disposable root canal filling.
