背景:氢氧化钙糊剂不仅可应用于直接盖髓、间接盖髓、根尖诱导等方面,目前在根管治疗过程中也得到了广泛应用.目的:观察氢氧化钙糊剂对根管预备封药后疼痛的影响.方法:选择中山大学附属第一医院口腔内科门诊患者752例,其中氢氧化钙组403例,在根管预备后使用螺旋输送器将氢氧化钙糊剂导入根管,氧化锌暂封;甲醛甲酚组349例,用镊子将蘸有甲醛甲酚溶液的纸尖导入根管,氧化锌暂封.1周后复诊,如出现疼痛则提前复诊并记录.结果与结论:氢氧化钙组11例(2.73%)、甲醛甲酚组51例(14.61%)出现封药后疼痛.两组封药后疼痛发生率差异有显著性意义(P <0.05).说明根管预备后,采用氢氧化钙糊剂作为根管消毒剂能有效降低根管预备封药后的疼痛发生率.

BACKGROUND: Calcium hydroxide paste can be applied not only in the direct pulp capping, indirect pulp capping and the apexification, presently it has been also widely used in the root canal treatment. OBJECTIVE: To observe the influence of calcium hydroxide cataplasm in preventing the pain after root canal preparation. METHODS: 752 patients were selected from the First Affiliated Hospital of Sun Yat-sen University. The cataplasms were sent into the root canal by using the screw conveyor in the calcium hydroxide group in which there were 403 patients, and the paper points with formocresol were sent into the root canal by using forceps in the formocresol group in which there were 349 patients. The root canal was temporarily closed with the zinc oxide in both two groups. Referral 1 week later and painful record were made. RESULTS AND CONCLUSION: There were 11 patients (2.73%) in the calcium hydroxide group and 51 patients (14.61%) in the formocresol group who had the medicament pain after root canal preparation. There was a significant difference in incidence of pain between the two groups (P < 0.05). The incidence of medicament pain after root canal preparation was effectively reduced by using the root canal disinfectant with the calcium hydroxide cataplasm.
