Examinations postbaseline were performed after 2 and 4 weeks. The reduction in measurable extrinsic stain in the baking soda gum group vs the breath mint control was statistically significant at 2 weeks (P < .0002) and at 4 weeks (P < .0008). Statistical analysis of the data revealed a significant change in extrinsic stain from baseline for both groups. The magnitude of the unadjusted longitudinal reduction in extrinsic stain in the baking soda gum group was 51% at 4 weeks.
