摘要
目的:观察1%次氯酸钠联合EDTA凝胶在根管治疗中的应用效果。方法:选择确诊为牙髓炎并拟行根管治疗的100例患者,患牙共100颗,随机分为观察组与对照组各50例(50颗患牙)。两组均使用裂钻、球钻等进行开髓并髓腔修整,对照组给予3%双氧水和生理盐水交替冲洗根管,观察组给予EDTA凝胶和1%次氯酸钠冲洗根管。根据两组患者根管预备后的疼痛发生率、出现疼痛的时间对疗效进行评价。结果:观察组疼痛发生率明显低于对照组(38%vs 74%,P<0.01)。根管预备后观察组和对照组在出现疼痛时间方面存在明显差异(8%vs 40%,≤24 h;30%vs 34%,>24 h;P<0.05)。结论:1%次氯酸钠联合EDTA凝胶用于根管治疗中能显著减轻术后急性炎症反应,减少疼痛发生,是较为理想的根管清理及根管预备辅助材料。
Objective： To explore the effects of 1% sodium hypochlorite plus EDTA gel on root canal therapy. Methods： One hundred cases （100 teeth） with root canal therapy were selected and randomly divided into an observation group （n=50, 50 teeth） and a control group （n=50, 50 teeth）. All the cases were treated with open dental pulp and the root canal was alternatively irrigated with 3% hydrogen peroxide and saline in the control group and 1% sodium hypochlorite plus EDTA gel in the observation group. The efcacy was assessed based on the incidence of pain and the time for pain onset. Results： The incidence of pain was significantly lower in the observation group than in the control group （38% vs 74%, P〈0.01 ）. There existed signifcantly diferences between the observation group and the control group in the time for pain onset after root canal preparation （8% vs 40%, ≤24 h; 30% vs 34%, 〉24 h; P〈0.05）. Conclusion： Sodium hypochlorite （1% concentration） plus EDTA gel can relieve postoperative acute infammatory reaction and reduce pain occurrence and are some ideal auxiliary materials for the cleaning and preparation of root canal.
