三种袋内冲洗制剂在早期种植体周围炎治疗中的疗效评价

目的对3种袋内冲洗液在早期种植体周围炎治疗中的临床疗效进行比较和评价。方法32例早期种植体周围炎患者龈下刮治术后，实验组分别用0．1％碘氧液、3％双氧水、0．2％洗必泰进行牙周袋内冲洗，术后每周冲洗1次，连续4周；对照组不进行牙周袋内冲洗。术前和术后4周分别检测MPI、GBI和PD。结果术后4周，碘氧液、双氧水、洗必泰及对照组MPI分别降低0．76，0．80，0．73和0．81，降低幅度各组无显著性差异（P〉0．05）；GBI分别降低0．62，0．62，0．67和0．43。IO、HP和CHX组降低幅度大于对照组．差异有显著性（P〈0．05），其中CHX组与对照组比较（P〈0．01），但碘氧液、双氧水、洗必泰组间无显著性差异（P〉0．05）。PD分别降低2．09mm，2．02mm，2．12mm和1．98mm，各组间差异均无显著性（P〉0．05）。结论含抗茵成分的袋内冲洗液有助于改善牙周组织的炎症状态，可提高龈下刮治在口腔种植体周围炎中的疗效。

Clinical Effects of Subgingival Irrigation Combined with Three Different Drug in Patients with Peri-implantitis

Objective To compare the effects of subgingival irrigation with different medications after subgingival scaling （SS） on clinical parameters in peri-implantitis. Methods 24 patients with peri-implantitis, were irrigated with 0.1% iodine oxide （KI ＋ H2O2, IO）, 3% hydrogen peroxide （HP）, 0.2 % chlorhexidine （CHX） respectively, the left one as control. Probing depth （PD）, supragingival plaque （MPI）, gingival bleeding on probing （GBI） was measured before SS as the baseline and four weeks after the treatment. Results In the 4th week after SS in combination with irrigation, MPI reduction was 0.76 - 0.81, without significant difference among these groups （P〉0.05）. GBI reduction was 0.43 - 0.67, and that in 0.1% iodine oxide, 3% hydrogen peroxide, 0.2% chlorhexidine was significantly higher than that in controls （P 〈 0.05）. No significant difference was found among 0.1% iodine oxide, 3% hydrogen peroxide and 0.2% chlorhexidine groups （P〉0.05）. PD reduction during the treatment was observed without significant differences among the groups. Conclusion Subgingival irrigation with iodine oxide, 3% hydrogen peroxide and 0.2% chlorhexidine, combined with SS can help improve the gingival inflammation status in treating.
