title: The efficacy of dentifrices on extrinsic tooth stains among community dwelling adults in India--a randomised controlled trial.
abstract: OBJECTIVE
  To examine the effects of routine use of two dentifrices on tooth stain.
  
  
  METHODS
  Single centre, parallel design, double blind randomised clinical study with two treatment groups.
  
  
  METHODS
  Department of Dental Public Health, SDM College of Dental Sciences and Hospital, Dharwad, Karnataka, India.
  
  
  METHODS
  125 of the 140 study subjects aged 18-70 years completed the 8-week study period.
  
  
  METHODS
  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.
  
  
  METHODS
  Modified Lobene tooth stain index.
  
  
  RESULTS
  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).
  
  
  CONCLUSIONS
  Routine use of the test dentifrice demonstrated significant removal of tooth stain among individuals recruited from the community.
