title: Comparison of two dentifrices with respect to efficacy for the control of plaque and gingivitis, and with respect to extrinsic tooth staining: a six-month clinical study on adults.
abstract: The objective of this six-month, double-blind clinical study, conducted in harmony with American Dental Association guidelines, was to provide a comparison between Colgate Total Toothpaste and Crest Gum Care Toothpaste with respect to their levels of efficacy for the control of supragingival dental plaque and gingivitis, and with respect to the levels of tooth staining associated with their use. Adult male and female subjects from the Edinburgh, Scotland area were entered into the study and stratified into two treatment groups which were balanced for age, sex, baseline Quigley-Hein Plaque Index scores and baseline Löe-Silness Gingival Index scores. Subjects received an oral prophylaxis, and 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 plaque, gingivitis and extrinsic tooth staining were conducted after three months' and again after six months' use of the study dentifrices. One-hundred and nine (109) subjects complied with the protocol and completed the entire six-month clinical study. At both the three- and six-month study examinations, the Colgate Total Toothpaste group exhibited statistically significantly less plaque, gingivitis and extrinsic tooth staining compared to the Crest Gum Care Toothpaste group. At the six-month examination, the magnitude of these differences exceeded 18% for all six parameters measured (18.7% for Plaque Index, 60.5% for Plaque Severity Index, 22.2% for Gingival Index, 85.1% for Gingivitis Severity Index, 45.3% for stain intensity, and 46.3% for stain area). Thus, the results of this six-month clinical study support the conclusion that Colgate Total Toothpaste provides a statistically significant, substantive advantage in efficacy for the control of plaque and gingivitis over Crest Gum Care Toothpaste, while, at the same time, providing better control against the development of extrinsic tooth staining.
