摘要
目的研究明胶海绵预防拔牙后并发症的临床效果。方法选择需行牙齿拔除术的598患者649颗牙齿为研究对象，分为实验组和对照组，实验组用明胶海绵对照组不使用明胶海绵。术后第二天第七天复查，判断拔牙后并发症的发生情况，计算发生率。比较差异性。结果实验组拔牙后并发症的发生率为6．45％，对照组为25．9％、两者差异有统计学意义（p〈0．05）。结论明胶海绵预防拔牙后并发症疗效肯定值得推广。
Objective To study the clinical effect of gelatin sponge on preventing the complication of teeth extraction. Methods 598 patients with 649 teeth extraction surgery is needed for the study,divided into experimental and control groups,the experimental group with a control group of gelatin sponge. Second and seventh day review, to determine the occurrence of complications after tooth extraction, calculated incidence. Compare the differ- ence. Results The experimental group, the incidence of complications after tooth extraction rate of 6.45 %, 25.9% in the control group, the difference was statistically significant（p〈0.05）. Conclusion Gelatin sponge prevention of tooth extraction complications efficacy certainly.
