This single-center, randomized, double-blind, two-treatment crossover clinical study evaluated the safety and efficacy of a stannous fluoride-containing dentifrice compared with a sodium fluoride control dentifrice for the control of intrinsic oral malodor. Adult subjects brushed twice daily with each product during separate treatment periods following standardized wash-out periods. Oral malodor was assessed using trained organoleptic judges applying a validated Odor Intensity (OI) scale at baseline and multiple post-treatment time points.
