目的 了解在氢氧化钙甘油糊剂中加入樟脑对氯苯酚后其临床疗效。方法 选择 183颗慢性根尖周炎患牙 ,随机分为 3组 :氢氧化钙 /樟脑对氯苯酚甘油 (A组 ,6 3例 )、氢氧化钙 /甘油 (B组 ,6 0例 )、樟脑对氯苯酚组 (C组 ,6 0例 ) ,对照观察封药 7天后的临床疗效及微生物培养结果。结果 A组约 84%病例在封药后一次复诊即可完成根管充填 ;B组仅 6 3%成功 ,而C组为 38% ,差异具有统计学意义。微生物学结果与此成正相关。结论 樟脑对氯苯酚可提高氢氧化钙的临床疗效 ,达到缩短疗程 ,降低药物副作用的目的。
Objective To investigate the clinical effect of adding camphor to p-chlorophenol in calcium hydroxide glycerol paste. Methods 183 teeth with chronic periapical periodontitis were randomly divided into three groups: calcium hydroxide / camphor p-chlorophenol glycerol (group A, 63 cases), calcium hydroxide / glycerol group B Camphor p-chlorophenol group (C group, 60 cases), the control sealant observed after 7 days of clinical efficacy and microbial culture results. Results About 84% of the cases in Group A completed root canal filling at the first visit after sealant treatment. In Group B, only 63% were successful, while 38% in Group C, the difference was statistically significant. Microbiological results are positively related to this. Conclusion Camphor on the chlorophenol can improve the clinical efficacy of calcium hydroxide, to shorten the course of treatment, reduce the side effects of drugs.
