Non-Nutritive Sweeteners Reduce The Adhesion Of Streptococcus mutans UA159 On Acrylic Resin Tooth.

[摘要] This work aimed to verify the influence of aspartame, steviol, sucralose and xylitol on the adhesion ofStreptococcus mutans UA159 on the surface of artificial teeth composed of acrylic resin. The in vitro adhesiontest was performed with the teeth immersed in artificial saliva for 48 hours at 37ºC. The biofilm formed wasquantified using the violet crystal technique. The control test used 10% sucrose and lactose, major adjuvants ofthe sweeteners. There was no bactericidal or bacteriostatic activity of the sweeteners. Although the pioneer cellswere viable under all conditions assessed, the adhesion was reduced by up to 33%. The highest and lowestpercentage of reduction were observed in the presence of xylitol and aspartame, respectively.
