To examine the effects of routine use of two dentifrices on tooth stain.
Single centre, parallel design, double blind randomised clinical study with two treatment groups.
Department of Dental Public Health, SDM College of Dental Sciences and Hospital, Dharwad, Karnataka, India.
125 of the 140 study subjects aged 18-70 years completed the 8-week study period.
Subjects were randomly assigned to brush twice daily with fluoride toothpaste (control) or a dentifrice formulated with silicas (test) and recalled for tooth stain examinations after 4 and 8 weeks of dentifrice use.
Modified Lobene tooth stain index.
Whereas statistical analyses indicate no significant differences between the treatment groups for baseline scores of tooth stain intensity, stain area and tooth stain composite scores (p > 0.53), examinations demonstrate significant reductions in stain area, intensity and stain composite scores amongst subjects assigned the test dentifrice at both recall visits versus the control (p < 0.05).
Routine use of the test dentifrice demonstrated significant removal of tooth stain among individuals recruited from the community.
