Plaque and Gingivitis
Figure 1. Percent Plaque Coverage
* Day 7 and Day 21 are Means adjusted for Day 0. For both groups, Day 7 and Day 21 scores were statistically significantly different (P<0.0001) from Day 0.
Figure 2. Gingivitis (Digital Gingival Imaging, a higher G-value indicates less gingivitis)
* Day 7 and Day 21 are Means adjusted for Day 0 For both groups, Day 7 and Day 21 scores were statistically significantly different (P<0.007) from Day 0.
Figure 3. Tooth color lightness (L*) change from baseline (Combined Arches, Analysis of Covariance)
To assess the effect of a daily 2-step dentifrice and gel system versus chlorhexidine (with regular brushing) using imaging of plaque, gingivitis and tooth color in an induced gingivitis model.
