PURPOSE
To examine the effect of toothbrushing with different brands of regular (Meridol, Colgate) and whitening toothpaste (Pearl Weiss, Rembrant, Email Diamant) on bacterial adhesion onto enamel surfaces in vitro.
MATERIALS AND METHODS
Extracted intact human teeth were brushed twice a day, for 3 minutes with the tested toothpaste for a period of 7 days. Sucrose dependent adhesion of Streptococcus mutans to the tested teeth was measured using pre-radioactive labeled bacteria.
RESULTS
S. mutans adhered more to enamel surfaces, pre-brushed with the tested toothpastes, than to teeth which were not brushed. Different profiles of bacterial adhesion were recorded. Both Diamant and Rembrant toothpastes increased bacterial affinity toward the enamel surface as compared to the other toothpastes. Meridol and Pearl Weiss demonstrated a similar adhesion effect as the etching control while brushing with Colgate demonstrated the least bacterial adhesion.
目的
研究使用不同品牌的普通牙膏（美利诺、高露洁）和美白牙膏（珍珠白、瑞诺、依美尔钻石白）刷牙对体外细菌在牙釉质表面黏附的影响。
材料与方法
完整的拔除人类牙齿每天用受试牙膏刷牙两次，每次3分钟，持续7天。使用预放射性标记的细菌测量变形链球菌对受试牙齿的蔗糖依赖性黏附。
结果
与未刷牙的牙齿相比，用受试牙膏预刷过的牙釉质表面变形链球菌黏附更多。记录到不同的细菌黏附情况。与其他牙膏相比，钻石白和瑞诺牙膏均增加了细菌对牙釉质表面的亲和力。美利诺和珍珠白牙膏在刷牙时表现出与酸蚀对照相似的黏附效果，而使用高露洁刷牙时细菌黏附最少。
