RT-qPCR检测CPC对中重度慢性牙周炎患者口内环境中红色复合体的影响
|
Abstract:
摘要 目的:利用RT-qPCR检测CPC对中重度慢性牙周炎患者口内环境中红色复合体构成比的影响。方法:临床选择40例中重度慢性牙周炎患者,随机分成CPC(试验)组、溶媒(对照)组,牙周基础治疗后分别使用该药品含漱+袋内冲洗。记录患者基线和用药4周后的临床指标;采集龈下菌斑、龈沟液和唾液样本,BANA试验检测胰蛋白酶样酶含量,RT-qPCR检测P.gingivalis、T.forsythia、T.denticola在总菌量中的构成比。结果:治疗后:1)试验组AL、BOP、PLI显著改善(P<0.01),对照组仅AL改善(P<0.01);2)两组龈下菌斑和龈沟液样本中胰蛋白酶样酶含量均显著下降(P<0.05);3)两组P.gingivalis构成比均显著下降(P<0.01),T.forsythia在试验组构成比显著下降(P<0.01),而T.denticola治疗前后无变化;4)P.gingivalis、T.forsythia、T.denticola两两之间构成比均显著相关(P<0.01)。结论:CPC可抑制牙菌斑形成,改善患者的临床症状,并对龈下菌斑中的P.gingivalis有一定的抑制作用,临床上可用于辅助治疗中重度慢性牙周炎
