AIM
The aim of this ex vivo study was to compare the antibacterial activity of total-etch and self-etch adhesive systems against Streptococcus mutans, Lactobacillus acidophilus, and Actinomyces viscosus through disk diffusion method.
MATERIALS AND METHODS
The antibacterial effects of Single Bond (SB) and Adper Prompt (AP) and aqueous solution of chlorhexidine 0.2% (positive control) were tested against standard strain of S. mutans, L. acidophilus, and A. viscosus using the disk diffusion method. The diameters of inhibition zones were measured in millimeters. Data was analyzed using Kruskal-Wallis test. Mann-Whitney U test was used for pairwise comparison.
RESULT
Of all the materials tested, AP showed the maximum inhibitory action against S. mutans and L. acidophilus. Aqueous solution of chlorhexidine 0.2% showed the maximum inhibitory action against A. viscosus. Very minimal antibacterial effect was noted for SB.
CONCLUSION
The antibacterial effects observed for the tested different dentin bonding systems may be related to the acidic nature of the materials.
目的
本体外研究的目的是通过纸片扩散法比较全酸蚀和自酸蚀粘结系统对变形链球菌、嗜酸乳杆菌和粘性放线菌的抗菌活性。
材料与方法
使用纸片扩散法测试单键（SB）、Adper Prompt（AP）以及0.2%洗必泰水溶液（阳性对照）对变形链球菌、嗜酸乳杆菌和粘性放线菌标准菌株的抗菌效果。以毫米为单位测量抑菌圈直径。数据采用Kruskal-Wallis检验进行分析。Mann-Whitney U检验用于两两比较。
结果
在所有测试材料中，AP对变形链球菌和嗜酸乳杆菌显示出最大抑制作用。0.2%洗必泰水溶液对粘性放线菌显示出最大抑制作用。SB的抗菌效果非常微小。
结论
观察到的不同牙本质粘结系统的抗菌效果可能与材料的酸性性质有关。
