目的 观察急性牙髓炎患者不同程度根管填充的近远期疗效.方法 将河南省省直第二医院2015年7月至2016年3月期间收治的96例急性牙髓炎患者随机分为A组、B组和C组,A组患者根管欠量填充,B组患者根管适量填充,C组患者根管超量填充,对三组患者进行为期6个月的随访,评价三组患者的近远期疗效.结果 B组患者治疗后1个月的疼痛率为8.6％,低于A组患者30.0％和C组患者的32.3％ (P ＜0.05),A组患者和C组患者治疗后1个月的疼痛率比较无明显差异(P＞0.05).B组患者治疗后2个月的咀嚼效率为(0.814±0.113),高于A组患者和C组患者的(0.705±0.109)和(0.692±0.101),A组与C组比较存在的差异无统计学意义(P＞0.05).B组患者治疗后3个月、6个月的治疗总有效率分别为91.4％ 、85.7％,与A组患者的80.0％、70.0％和C组患者的71.0％、58.1％比较存在的差异均具有统计学意义(P＜0.05).A组患者治疗后3个月、6个月的总有效率高于C组(P＜0.05).结论 对急性牙髓炎患者实施适度根管填充治疗,可获得确切的近远期疗效.“,”Objective To observe the short-term and long-term effect of different degrees of root canal filling in patients with acute pulpitis.Methods Ninety-six case of patients with acute pulpitis were randomly divided into three groups:group A,group B,group C,three groups were followed up for 6 months.The short-term and long-term curative effects of the three groups were evaluated.Results The pain rate was 8.6％ in one month after treatment,30.0％ in A group and 32.3％ in C groups (P ＜0.05).In group A and group C,the pain rate was 1 month after treatment pain rate was no significant difference (P ＞ 0.05).The masticatory efficiency at 2 months after treatment was (0.814 ±0.113),which was higher than that in group A and group C (0.705 ± 0.109) and (0.692 ± 0.101),and there was no significant difference between group A and group C Statistical significance (P ＞ 0.05).The total effective rates in group B were 91.4％ and 85.7％ at 3 months and 6 months after treatment respectively,which were significantly higher than those of the three groups (71.0％ vs 58.0％,80.0％ and 70.0％,respectively).With statistical significance (P＜0.05).The total effective rates of group A and group C were higher than those of group C (P ＜0.05).Conclusion Appropriate root canal filling in patients with acute pulpitis can obtain definite short-term and long-term curative effect.
