目的对比两种根管填充方法对于根管术后患者疼痛程度的观察。方法选择我院口腔科2009年5月至2011年12月收治的64例慢性根尖周炎患者做为研究对象,64例慢性根尖周炎64颗第一磨牙。将所有患者严格按照随机分组原则分为一次根管填充组和二次根管组各32例。分别采用一次法,二次法进行根管充填,对比2组患者1周内疼痛程度及2周内急症反应发生率。结果两组疼痛度具有显著差异,二次根管填充术患者疼痛程度显著高于一次填充组患者,且随访2周内急症发生率二次填充组高于一次填充组,且差异均有统计学意义(P<0.05)。结论使用一次法高质量根管填充术治疗慢性根尖周炎患者具有良好的效果,术后疼痛度小,患者更易耐受,且急症发生率低。值得临床广泛推广使用。
Objective To compare the effects of two root canal filling methods on postoperative pain in patients with root canal. Methods Sixty-four patients with chronic periapical periodontitis admitted from May 2009 to December 2011 in our hospital were selected as study objects, and 64 patients with chronic periapical periodontitis 64 first molars. All patients were divided into two groups, primary root canal filling group and secondary root canal group in strict accordance with the principle of randomization. The primary and secondary methods were used for root canal filling respectively. The pain level in 1 week and the incidence of acute and acute reactions within 2 weeks were compared between the two groups. Results There was a significant difference in pain between the two groups. The degree of pain in the secondary root canal filling group was significantly higher than that in the primary filling group. The incidence of acute illness in the secondary filling group was higher than that in the primary filling group within 2 weeks of follow-up, and the differences were statistically significant Significance (P <0.05). Conclusions The use of one-time high-quality root canal filling in the treatment of patients with chronic periapical periodontitis has a good effect. The postoperative pain is small, the patients are more tolerable, and the incidence of acute illness is low. It is widely used in clinical practice.
