Table 3.

Absorbance values (412 nm) and percent inhibition of total MMP activity after treatment of demineralized beams with benzalkonium chloride in 0.5 % and 1.0 % for 60 s. using the SensoLyte Generic MMP assay kit, relative to an untreated control with 0% inhibition of total MMP activity.

	Control (ABU)	0.5% BAC	1.0% BAC
Absorbance (412 nm)	0.638 (0.17) ^A	0.440 (0.09) ^B	0.292 (0.06) ^C
% MMP inhibition	0.0 (0.0) ^A	31.0 (14.1) ^B	54.2 (9.0) ^C

Values are means ± SD (n = 10). Groups identified by different letters are significantly different (p<0.05).
