本研究旨在评估局部应用百里醌凝胶作为慢性牙周炎患者洁治和根面平整(SRP)辅助疗法的潜在益处。 根据纳入和排除标准选20个受试者的40个位点,受试者分为两组。组I受试者(SRP联合百里醌)和组II对照组受试者(仅SRP)。基线和手术后6周进行检测各种临床参数,包括菌斑指数(PI),牙龈指数(GI),探诊深度(PPD)和附着水平(RAL)。基线和手术后6周评估龈沟液(GCF)中的碱性磷酸酶(A

本研究旨在评估局部应用百里醌凝胶作为慢性牙周炎患者洁治和根面平整(SRP)辅助疗法的潜在益处。

根据纳入和排除标准选20个受试者的40个位点,受试者分为两组。组I受试者(SRP联合百里醌)和组II对照组受试者(仅SRP)。基线和手术后6周进行检测各种临床参数,包括菌斑指数(PI),牙龈指数(GI),探诊深度(PPD)和附着水平(RAL)。基线和手术后6周评估龈沟液(GCF)中的碱性磷酸酶(ALP)的水平。此外,使用3种细菌评估百里醌的抗微生物效果。

结果显示,PI、GI和PPD明显降低,差异有统计学意义,两组中RAL和GCF ALP的水平从基线到手术后6周增加。组I和组II之间相比,前者PPD和GCF-ALP水平显著降低,而RAL的水平升高,但在6周时在PI和GI中没有观察到统计学差异。在0.2%百里醌凝胶的微生物学评估中,观察到其对牙龈卟啉单胞菌、放线菌和中间普式菌敏感。

在当前的研究中发现了临床和生化参数的明显变化。因此,可以得出结论,0.2%胸腺嘧啶醌凝胶的临床内应用可能是SRP治疗慢性牙周炎的有益辅助手段。
