目的探讨下颌阻生第三磨牙患者拔牙术后干槽症的预防方法。方法随机将200例下颌第三磨牙阻生患者分为两组。100例患者于常规拔牙术后牙槽窝置入碘仿、替硝唑明胶海绵药卷作为治疗组,另100例患者常规拔牙术后未特殊处理牙槽窝作为对照组,观察两组患者术后干槽症发生情况。结果治疗组干槽症发生1例,发生率1%,对照组干槽症发生11例,发生率11%。结论下颌阻生第三磨牙患者拔牙术后牙槽窝置入碘仿、替硝唑明胶海绵药卷可有效预防干槽症的发生,方法简便,值得临床推广使用。
Objective To investigate the prevention of dry socket after extraction of mandibular third molar patients. Methods 200 cases of mandibular third molar impacted patients were randomly divided into two groups. 100 cases were treated with tinidazole and tinidazole gelatin sponge as the treatment group in the alveolar socket after conventional tooth extraction. The other 100 cases were treated with no special treatment of the alveolar socket after tooth extraction, and the two groups were treated After the occurrence of dry socket disease. Results In the treatment group, 1 case of dry socket occurred, the incidence rate was 1%. In the control group, dry socket was found in 11 cases, the incidence rate was 11%. Conclusions Implantation of iodoform in the alveolar socket of the third molars with mandibular impaction can effectively prevent the occurrence of dry socket syndrome. The method is simple and worthy of clinical application.
