目的比较樟脑酚与氢氧化钙作为填充药物在根管治疗中的临床效果。方法选取2015年1—10月武汉市中医医院收治的接受根管治疗患者68例(76颗患牙),随机分为观察组34例(38颗患牙)与对照组34例(38颗患牙)。观察组给予氢氧化钙填充,对照组给予樟脑酚填充。比较两组患者治疗前后患牙疼痛评分、活动度评分及临床疗效。结果治疗前两组患者患牙疼痛评分、活动度评分比较,差异无统计学意义(P>0.05);治疗后观察组患者患牙疼痛评分、活动度评分低于对照组,差异有统计学意义(P<0.05)。观察组总有效率高于对照组,差异有统计学意义(P<0.05)。结论在根管治疗中氢氧化钙作为填充药物临床效果优于樟脑酚,氢氧化钙对内毒素有良好的灭活性,可提高根尖孔封闭性,有效改善患者临床症状。
Objective To compare the clinical effects of camphor and calcium hydroxide as filling drugs in root canal therapy. Methods Sixty-eight patients (76 teeth) receiving root canal therapy from January to October 2015 in Wuhan Chinese Medicine Hospital were randomly divided into 34 cases (38 teeth) in the observation group and 34 cases (38 patients) in the control group tooth). The observation group was given calcium hydroxide filling, and the control group was given camphor phenol filling. Tooth pain scores, activity scores and clinical outcomes of two groups before and after treatment were compared. Results There was no significant difference in dental pain score and activity score between the two groups before treatment (P> 0.05). After treatment, the dental pain score and activity score of the observation group were lower than those of the control group, the difference was statistically significant (P <0.05). The total effective rate of observation group was higher than that of control group, the difference was statistically significant (P <0.05). Conclusions Calcium hydroxide is superior to camphor phenol in root canal therapy as filling drug. Calcium hydroxide has a good inactivation to endotoxin, which can improve the apical hole sealing and effectively improve the clinical symptoms.
