目的:观察低浓度(0.5%、2.5%)聚维酮碘(Povidone-iodine,PVP-I)取代蒸馏水作为超声龈下刮治和根面平整术(scaling and root planning,SRP)的同步冲洗液的临床疗效。方法:选择中度和重度牙周病病人45人共3 240个位点,随机分为3组,对照组...目的:观察低浓度(0.5%、2.5%)聚维酮碘(Povidone-iodine,PVP-I)取代蒸馏水作为超声龈下刮治和根面平整术(scaling and root planning,SRP)的同步冲洗液的临床疗效。方法:选择中度和重度牙周病病人45人共3 240个位点,随机分为3组,对照组用蒸馏水作为同步冲洗液进行全口超声SRP;实验1组和实验2组分别用0.5%和2.5%的PVP-I为同步冲洗液进行全口超声SRP。基线后1个月和3个月复查菌斑指数(PLI)、探诊后出血(BOP)、牙周袋深度(PD)和临床附着水平(CAL)。结果:治疗后3组各项指标与治疗前比较均有明显改善(P<0.05),实验1组及实验2组疗效均好于对照组(P<0.05),但两实验组之间比较未见明显差异(P>0.05)。结论:0.5%和2.5%的PVP-I较蒸馏水作为超声SPR的同步冲洗液均能提高治疗效果,两实验组无明显差异。展开更多
