不同根管充填方法治疗慢性牙髓炎的对比研究

Comparative study of different root canal filling methods in the treatment of chronic pulpitis

目的:对比分析冷牙胶侧方加压根管充填、热牙胶垂直加压根管充填治疗慢性牙髓炎的应用效果。方法:回顾性分析本院2020年7月至2022年9月收治慢性牙髓炎132例患者的临床资料。根据根管填充方法的不同将患者分为对照组(冷牙胶侧方加压根管充填,n=63)和观察组(热牙胶垂直加压根管充填,n=69)。术后通过X线观察填充情况,术前后记录牙周袋探诊深度(Periodontal depth,PD)、牙龈指数(Gingival index,GI)及通过视觉疼痛模拟评分(Visual analog score,VAS)评价疼痛程度。结果:对照组恰填占比为73.01%,观察组占比为89.85%,观察组填充情况显著优于对照组(P<0.05)。两组PD、GI均显著下降,且观察组PD、GI均显著低于对照组(P<0.05)。两组VAS评分随着时间增长而下降,且观察组术后3 d、7d VAS评分均显著低于对照组(P<0.05)。结论:热牙胶垂直加压根管充填与冷牙胶侧方加压根管充填相比较,前者填充效果更佳,可显著改善牙周相关指数,降低疼痛程度。

Objective:To compare and analyze the effect of lateral compression root canal filling with cold gum and vertical compression root canal filling with hot gum in the treatment of chronic pulpitis.Methods:The clinical data of 132 patients with chronic pulpitis treated in our hospital from July 2020 to September 2022 were retrospectively analyzed.According to different filling methods,the patients were divided into control group(cold glue lateral compression root canal filling,n=63)and observation group(hot glue vertical compression root canal filling,n=69).The filling condition was observed by X-ray after operation.periodontal depth(PD)and Gingival index(GI)were recorded before and after operation.The pain degree was evaluated by Visual analog score(VAS).Results:The proportion of just filling in control group was 73.01%,and that in observation group was 89.85%.The filling in observation group was significantly better than that in control group(P<0.05).PD and GI of the two groups were significantly decreased,and PD and GI of the observation group were significantly lower than those of the control group(P<0.05).VAS scores of the two groups decreased with the increase of time,and the 3d and 7dVAS scores of the observation group were significantly lower than those of the control group(P<0.05).Conclusion:The filling effect of vertical compression root canal filling with hot dental glue is better than that of lateral compression root canal filling with cold dental glue,which can significantly improve the periodontal index and reduce the degree of pain.
