A six-week clinical efficacy study of a tooth whitening tartar control dentifrice for the removal of extrinsic tooth stain.
The objective of this double-blind clinical study was to investigate the tooth whitening efficacy of a new commercially available calculus-inhibiting dentifrice (Colgate Tartar Control Plus Whitening Fluoride dentifrice) containing tetra-sodium pyrophosphate, sodium tripolyphosphate, and PVM/MA copolymer in a 0.243% sodium fluoride/silica base (test dentifrice), compared to a commercially available, non-tooth whitening dentifrice containing 0.243% sodium fluoride in a silica base (control dentifrice). Following a baseline examination for, extrinsic tooth stain, qualifying adult male and female subjects from the Manchester, United Kingdom area were randomized into two treatment groups which were balanced for gender, age and level of extrinsic tooth stain. Subjects were instructed to brush their teeth twice daily (morning and evening) for one minute with their assigned dentifrice using a soft-bristled toothbrush. Examinations for extrinsic tooth stain were repeated after six weeks' use of the study dentifrices. Seventy-nine(79) subjects complied with the protocol and completed the entire study. At the six-week examination, subjects assigned to the test dentifrice treatment group exhibited statistically significant reductions of over 40% with respect to both extrinsic tooth stain area and extrinsic tooth stain intensity relative to those subjects assigned to the control dentifrice treatment group.
