Clinical evaluation of the stain removing ability of a whitening dentifrice and stain controlling system

This study aimed to evaluate the stain removing/controlling properties of a whitening dentifrice and a stain controlling system, in a parallel group, multiple use study. Subjects (63), were stratified according to baseline stain scores and randomly allocated to a group, A (standard dentifrice), B (whitening/stain removing dentifrice) or C (whitening/stain removing dentifrice, tooth polish, tooth polisher and whitening/stain removing mouthwash). At each attendance, extrinsic stain was scored blind by a trained and calibrated examiner using the Shaw and Murray Stain Index, under constant lighting conditions. In addition, whiteness was measured using a colorimeter. The toothpaste regimens were well balanced at baseline ( p=0.811). At 4 weeks, Regimens B and C had significantly less stain than A ( p
