目的对比研究聚维酮碘明胶海绵与胶质银明胶海绵在预防拔牙术后疼痛、出血、感染、干槽症等并发症的临床应用效果。方法选择需择期行牙齿拔除术的患者748例793颗牙齿为主要研究对象,以半随机单盲对照方法分为聚维酮碘明胶海绵组(聚维酮碘组)和胶质银明胶海绵组(胶质银组),均采用局部麻醉,患牙拔除后搔刮干净牙槽窝,聚维酮碘组植入聚维酮碘明胶海绵填塞牙槽窝,胶质组待牙槽窝内血液充塞后填塞胶质银明胶海绵,术后3h、24h、1周复查后观察二组拔牙术后并发症的发生情况。结果聚维酮碘组术后出血症的发生率明显低于胶质银组,比较结果有统计学意义(P<0.05);胶质银组术后感染少、肿胀轻,与聚维酮碘组比较结果差异有统计学意义(P<0.05);二组患者术后疼痛感及干槽症的发生率比较差异无统计学意义(P>0.05)。结论聚维酮碘明胶海绵对术后出血治疗效果明显,而胶质银明胶海绵对预防拔牙术后感染及肿胀疗效肯定,临床应用各有千秋,均可推广借鉴。
Objective To compare the clinical effects of povidone-iodine gelatin sponge and glial silver gelatin sponge in the prevention of complications such as pain, hemorrhage, infection and dry mouth after dental extraction. Methods A total of 748 patients with 793 teeth undergoing elective dental extraction were selected as the main study subjects. They were divided into two groups: Povidone iodine gelatin sponge (Povidone iodine group) and glial silver gelatin sponge (Colloidal silver group), were used local anesthesia, tooth removal after scratching clean alveolar fossa, Povidone iodine group implanted with povidone-iodine gelatin sponge to fill the alveolar fossa, glial cavity of the alveolar tissue Stuffed and stuffed with glial silver gelatin sponge, 3h, 24h, 1 week after the review after the observation of the occurrence of complications after two groups of dental extraction. Results The incidence of postoperative bleeding in the povidone-iodine group was significantly lower than that in the glial silver group (P <0.05). The glial silver group had less postoperative infection, less swelling and povidone-iodine The difference between the two groups was statistically significant (P <0.05). There was no significant difference in postoperative pain and dry socket between the two groups (P> 0.05). Conclusion Povidone-iodine gelatin sponge has obvious curative effect on postoperative hemorrhage. However, glial silver gelatin sponge has certain curative effect on preventing infection and swelling after tooth extraction. The clinical application has its advantages and can be used for reference.
