口腔是一个复杂的微生物环境,正常情况下口内细菌处于平衡状态,当其存在一定刺激(如拔牙)时口内菌群发生变化,而拔牙术后的细菌感染则成为一种常见的术后并发症,也成为口腔医师的预防医学研究方向。通过比较学者的研究数据,结合收集口腔门诊的有效反馈信息,我们初步推测出最合适的预防用药方案为术前术后均适量使用头孢一代及奥硝唑。 Oral cavity is a complex microbial environment. Under normal circumstances, oral bacteria in a balanced state, when there is a certain stimulation (such as tooth extraction) oral flora change, and bacterial infection after tooth extraction has become a common postoperative complications , Has become the stomatology preventive medicine research. By comparing scholar’s research data and collecting effective feedback from oral clinic, we initially estimated that the most suitable prophylaxis regimen was appropriate cefotaxime and ornidazole for preoperative and postoperative.
