Log transformation of QLF-D parameters on the effect of violet-blue light on the lesion depth by image analysis of loss of fluorescence on human enamel specimens by S. mutans biofilm grown in TSB or TSBS through QLF-D. S. mutans in TSB had no significant group differences for any of the QLF-D parameters. TSBS baseline had significantly lower QLF-D parameters than Blue (p < 0.001) and No Blue (p < 0.0001), while Blue and No Blue were not significantly different from one another (p > 0.08).
