摘要
目的评价自固化磷酸钙人工骨(CPC)对可能超填根管的临床疗效。方法根管预备30号、35号扩大针无阻力穿出根尖孔患牙125颗,共180个牙根。随机分两组,A组:充填CPC及牙胶尖;B组:充填氢氧化钙碘仿糊剂加牙胶尖。充填后X线片观察超填情况,对超填者充填后1周、3个月、6个月的临床表现进行观察。结果超填度评分A组为1.78,B组为1.64,两组比较无统计学意义(P>0.05)。超填后1周、3个月、6个月疗效评价有高度统计学意义(P<0.01)。结论根管可能超填病例,用CPC根充更理想。
Objective To investigate the clinical efficacy of autosolidifying calcium phosphate cement (CPC) in treatment of the root canals might be uhra-filled. Methods In root canal preparation, there were 125 teeth, a total of 180 roots which were pierced through the apical foramen with no resistance using No.30 and No.35 root canal reamer. These teeth were randomly divided into two groups. Group A: root canals were filled with CPC and gutta-percha, group B: root canals were filled with calcium hydroxide iodoform paste and gutta-percha. After filling, the X-ray films were observed over all the roots. The over-filled roots were observed of clinical performance respectively after 1 week, 3 months, 6 months. Results The ultra-filled score mean: group A was 1.78, and group B was 1.64. There was no significant difference between the two groups (/9 〉 0.05). After filling over 1 week, 3 months, 6 months, there were statistical differences in efficacy evaluation (P 〈 0.01). Conclusion Using CPC to fill the roots which was pierced through the apical foramen (roots may be over- filled) is more ideal.
