不同锥度牙胶尖充填同一锥度根管临床疗效观察

Clinical curative effects of the same taper root canal obturated with different gutta percha cones

目的比较0.02锥度与0.06锥度牙胶尖在充填同一锥度根管时临床疗效的差异。方法选择大坪医院口腔科就诊的牙髓病或根尖周病患者80颗,按就诊顺序排列随机分为两组,分别采用0.02锥度牙胶尖(A组)和0.06锥度牙胶尖(B组)进行根管充填。对两组患牙的根管充填时间、根管充填效果和治愈率(术后3、6个月和1年复查)进行比较,并拍摄X线片进行记录。结果 A组适填58根管,超填2根管,欠填2根管;B组适填68根管,超填1根管,欠填2根管。以根管为单位,A组根管充填时间平均(145.9±14.3)s,B组平均(95.6±17.8)s(P<0.05)。结论 0.02锥度与0.06锥度牙胶尖充填根管在临床疗效上差异无统计学意义(P<0.05)。0.06锥度牙胶尖充填根管时间短,操作简便,适合于临床推广应用。

Objective To compare the clinical efficacy of the same taper root canal obturated therapy between 0.02 tapered and 0.06 tapered gutta percha.Methods Eighty patients with pulpitis or periapical diseases treated in our hospital were randomly divided into two groups,whose teeth were filled by 0.02 tapered（group A）and 0.06 tapered gutta percha（group B）,respectively.The obturation time,outcomes and recovery rate（at postoperative 3 months,6 months and one year follow-ups） were recorded and compared.Preoperative and postoperative radiographs of each tooth were taken.Results There were 58 root canals which were suitable filled,2 over-filled and 2 under-filled in group A;there were 68 root canals which were suitable filled,one over-filled and 2 under-filled in group B.The average obturation time per canal was（145.9±14.3）s in group A and（95.6±17.8）s in group B（P〈0.05）.Conclusion There is no significant difference on clinical outcomes between 0.02 tapered and 0.06 tapered gutta percha.However,the 0.06 tapered gutta percha have shorter obturation time and is easy to operate,which is suitable for clinical application.
