摘要/Abstract

摘要： 目的: 通过体内外实验探究人参皂苷Rh2对致龋生物膜的作用。方法: 运用结晶紫染色法和激光共聚焦扫描显微镜观察Rh2对体外生物膜的影响。建立大鼠龋齿模型,取颌骨进行显微断层扫描,Keyes龋齿计分,评价Rh2的抗龋作用。结果: 体外实验结果表明Rh2能明显抑制生物膜上致龋菌生长,减少胞外基质。动物实验中,Rh2组磨牙体积和窝沟区域矿物密度大于对照组(P<0.05)。Rh2组磨牙龋齿计分都低于对照组(P<0.05)。结论: Rh2能在体外抑制致龋生物膜形成,体内有一定的抗龋保护能力。

Abstract: Objective: To explore the effect of ginsenoside Rh2 on cariogenic biofilm in vivo and in vitro.Methods: Crystal violet staining and laser scanning confocal microscopy were used to observe the effect of Rh2 on biofilm in vitro.A dental caries rat model was established.Microtomographic examination of the jaw bone and Keyes caries score were used to evaluate the protective effect of Rh2 on dental caries.Results: In vitro experiments showed that Rh2 significantly inhibited the growth of cariogenic bacteria on the biofilm and reduced the extracellular matrix.In animal experiments, the volume and density of pit area in the molars of group Rh2 rats were higher than those of the control group (P<0.05).The caries scores of the molar in group Rh2 rats were lower than that in the control group (P<0.05).Conclusion: Rh2 can inhibit cariogenic biofilm formation in vitro and protect rats from dental caries.
