智齿冠周炎炎症急性期与缓解期拔牙的疗效

目的：观察不同时期拔牙术用于智齿冠周炎的实际疗效，探讨最佳治疗时机。方法：选择94例智齿冠周炎患者，随机分为观察组47例及对照组47例，前者采用即刻拔牙术进行治疗，后者待炎症缓解后行拔牙术治疗，记录两组患者手术时间、疗效及不良反应。结果：两组患者拔牙用时无显著性差异（P＞0.05），观察组疗效显著优于对照组（P＜0.05），抗生素用药时间显著较对照组短（P＜0.05）。结论：于智齿冠周炎炎症急性期行拔牙术并未增加手术时间，且显著提升了疗效，减少了抗生素的使用，是一种更为科学合理的治疗方案。

Extraction efficacy on pericoronitis of wisdom tooth between acute and remission phase

To observe the extracti on efficacy on pericoronitis of wisdom tooth between acute and remission phase in order to explore the best time for treatment. Methods： 94 cases of pericoronitis of wisdom tooth were randomly divided into the observation group and control group（47 cases in each group） in which immediate extraction technique was used in the observation group and extraction technique was used after relieving inflammation . Operative time , efficacy and adverse reactions were observed in two groups . Results：No significant difference（P〉0.05） of extraction time in two groups ,the efficacy in the observation group was significantly better than that in the control group（P〈0.05）,antibiotic treatment time was significantly shorter in the observation group than that in the control group （P〈0.05）. Conclusion： Immediate extraction technique is a more scientific and reasonable treatment for acute phase of pericoronitis of wisdom tooth,which reduce the operation time and the use of antibiotics.
