Bacteria beneath 58 class V Concise restorations on permanent molars in vivo were registered. After an observation period of 1-4 months bacteria were found in all 13 cavities filled with Concise only, in 14 out of 15 cavities filled with resin and Concise, in 12 out of 15 acid-etched cavities with Concise only and in 8 out of 15 acid-etched cavities filled with resin and Concise. Only the difference between the two procedures: Concise only and acid + resin + Concise, was significant. The occurrence of bacteria in the dentinal tubules beneath the cavities was greatest when the cavities had been etched.
对体内恒磨牙上58个V类简洁修复体下方的细菌进行了记录。经过1至4个月的观察期后，发现仅用简洁材料填充的所有13个窝洞中都有细菌，在15个用树脂和简洁材料填充的窝洞中，有14个发现了细菌，在15个仅用简洁材料酸蚀的窝洞中，有12个发现了细菌，在15个用树脂和简洁材料填充并酸蚀的窝洞中，有8个发现了细菌。只有两种操作之间的差异具有统计学意义：仅使用简洁材料和酸蚀+树脂+简洁材料。当窝洞进行酸蚀时，窝洞下方牙本质小管中细菌的出现率最高。
