OBJECTIVE
To determine the E. faecalis biofilm formation on the surface of five adhesive systems (AS) and its relationship with roughness.
STUDY DESIGN
The formation of E. faecalis biofilms was tested on the surface of four dual-cure AS: AdheSE DC, Clearfil DC Bond, Futurabond DC and Excite DSC and one light-cure antimicrobial AS, Clearfil Protect Bond, after 24 hours of incubation, using the MBEC high-throughput device.
RESULTS
E. faecalis biofilms grew on all the adhesives. The least growth of biofilm was on Excite DSC, Clearfil Protect Bond, and the control. Futurabond DC resulted in the greatest roughness and biofilm amount. There was a close relationship between the quantity of biofilm and roughness, except for Clearfil Protect Bond, which showed little biofilm but high roughness.
CONCLUSION
None of the tested AS prevented E. faecalis biofilm formation, although the least quantity was found on the surface of Clearfil Protect Bond.
目的
确定五种黏接系统（AS）表面上粪肠球菌生物膜的形成及其与粗糙度的关系。
研究设计
在 24 小时孵育后，使用 MBEC 高通量设备，在四种双固化 AS（AdheSE DC、Clearfil DC Bond、Futurabond DC 和 Excite DSC）和一种光固化抗菌 AS（Clearfil Protect Bond）表面上测试粪肠球菌生物膜的形成。
结果
粪肠球菌生物膜在所有黏接剂上均有生长。在 Excite DSC、Clearfil Protect Bond 和对照组中，生物膜的生长最少。Futurabond DC 导致最大的粗糙度和生物膜量。除了 Clearfil Protect Bond 之外，生物膜的数量与粗糙度之间存在密切关系，尽管后者的生物膜量较少，但粗糙度较高。
结论
虽然在 Clearfil Protect Bond 表面发现的生物膜量最少，但测试的 AS 均不能防止粪肠球菌生物膜的形成。
