Comparison of the cell compatibility of the titanium surface that underwent the combination treatment (Ag(+)L(+)) or silver ion application (Ag(+)L(−)) after ultrasound scaling on A. actinomycetemcomitans biofilm or non-infected titanium surface. (A) cell proliferation, (B) cell calcification. Significant differences (p < 0.05) between the groups are denoted by different superscript letters (i.e., bars with the same letter are not significantly different).
