目的:探讨碧兰糊剂与氧化锌丁香油糊剂在根管治疗中的应用效果比较,为选择更为有效的根管充填材料提供实践依据。方法:选取门诊2010年4月至2012年3月收治的需要进行根管治疗的急慢性牙髓炎及根尖周病的患者120例,随机分为2组即观察组60例(碧兰糊剂根充组),对照组60例(氧化锌丁香油糊剂充填组),进行常规根管预备后分别采用以上两种糊剂进行充填,比较2组治疗效果。结果:观察组近期成功率为97.3%,远期成功率为92.0%;对照组近期成功率为97.2%,远期成功率为79.5%。2组近期成功率比较差异无统计学意义(P>0.05),远期成功率比较差异有统计学意义(P<0.01)。结论:碧兰糊剂安全可靠、疗效确切,是一种较为理想的根管充填材料,值得临床推广应用。
OBJECTIVE: To compare the application effect of Pilan paste and zinc oxide clove oil paste in root canal therapy, and to provide a practical basis for choosing a more effective root canal filling material. Methods: A total of 120 patients with acute and chronic pulpitis and periapical periodontitis undergoing root canal therapy from April 2010 to March 2012 were selected and randomly divided into two groups (60 in observation group) 60 rats in the control group (zinc oxide clove oil paste filling group). After conventional root canal preparation, they were respectively filled with the above two kinds of pastes to compare the therapeutic effect of the two groups. Results: The success rate of the observation group was 97.3% and the long-term success rate was 92.0%. The recent success rate of the control group was 97.2% and the long-term success rate was 79.5%. There was no significant difference in success rate between the two groups (P> 0.05), and the long-term success rate was significantly different (P <0.01). Conclusion: Bilan paste is safe, reliable and effective, which is an ideal root canal filling material, which is worthy of clinical application.
