Cortisomol糊剂治疗慢性根尖周炎急性发作的临床疗效

Clinical effect of Cortisomol in acute inflammation of chronic apical periodontitis

目的：观察Cortisomol糊剂用于慢性根尖周炎急性发作后引起的急性肿痛根管充填治疗的临床疗效,为其在牙髓炎的应急处理治疗中推广使用提供确切依据。方法：选择临床80例40岁以上中老年人下颌牙牙体因楔状缺损、龋坏等各种不同原因造成露髓引起的慢性根尖周炎病患者,随机分2组,按照Protaper机用镍钛根管锉产品使用规则,采用逐步深入法进行根管预备后2~3 d,出现的急性肿痛等相关并发症,当行使常规手段无法缓解时,治疗组以Cortisomol根管糊剂和牙胶尖侧方加压法进行一次性根管充填,对照组利用氢氧化钙与碘酚配合处理急性发作数天后用丁香油氧化锌糊剂和牙胶尖侧方加压法进行实施常规根管充填进行比较分析;观察两组的疗效。结果：治疗组以Cortisomol糊剂一次法根管充填在24 h后显效,显效率95.67%;而对照组24 h后显效率达60%,48 h后逐渐显效率增加,两组差异有显著性（P〈0.05）。结论：Cortisomol糊剂根充治疗慢性牙髓炎急性发作后引起的急性肿痛效果显著,值得推广应用。

Objective： To observe the clinical curative effect of the treatment using Cortisomol on acute inflammation root canal therapy which effected by the acute attack of chronic apical periodontitis.It aims to offer the exact basis for the promotion of the urgent therapy of pulpitis.Methods： 80 clinical middle-aged or old-aged people who are more than 40 and suffered chronic apical periodontitis because of Wedge-shaped defect and Dental caries of the mandibular teeth were selected.These patients were divided into 2 groups randomly.According to the rules of Hand ProTaper NiTi instruments products,after 2 or 3 days of root canal preparation using the gradually penetration method,and acute swelling and relative syndromes appear,and when the syndromes can not be relieved using regular methods,the therapy group were carried out the disposable root canal filling up using Cortisomol root canal pastes and Root-canal obturating points in Lateral pressure,the comparison group uses calcium hydroxide and Iodine phenol after several days to compare the effect.The therapy effect of two groups was evaluated.Results： After 24 hours the effect can be seen in thetherapy group,the ratio was 95.67%,The control group＇ ratio is only 60% after 24 hours,the differences between these two groups are clear（P〈0.05）.After 48 hours,the effect ratio increases.Conclusion： The effect of treatment of Cortisomol therapy on acute swelling which is aroused by chronic pulpitis is notable.
