Purpose: To investigate in a double-blind clinical study the effectiveness of a dentifrice containing triclosan and a copolymer (Colgate Total Toothpaste) for controlling breath odor 12 hours after brushing the teeth., Methods: A panel of four expert judges using a nine-point hedonic scale evaluated breath odor. Following a baseline evaluation of breath odor, prospective study subjects who presented breath odor scores above the threshold value for unpleasant breath odor were stratified by score, and randomized into two treatment groups. Subjects were provided with a soft-bristled toothbrush, and brushed their teeth thoroughly in their regular and customary manner with their assigned dentifrice. Subjects refrained from dental hygiene, breath mints, or mouthrinses for the next 12 hours, after which they were once again evaluated for breath odor. 76 adult male and female subjects from the Mississauga, Ontario, Canada area participated in the study., Results: At 12 hours after brushing their teeth, subjects in both dentifrice treatment groups presented mean breath odor scores which were statistically significantly lower than the mean scores observed at baseline. However, the difference between the mean 12-hour breath odor score for the Colgate Total group was 4.65, which is within the range of values corresponding to pleasant breath odor; whereas the mean 12-hour breath odor score for the placebo group was 6.11, which is above the threshold value corresponding to unpleasant breath odor. Thus, the results of this double-blind study, conducted according to Guidelines by the Council on Scientific Affairs of the American Dental Association, support the conclusion that Colgate Total dentifrice provides effective control of breath odor at 12 hours after brushing the teeth.

Objective: The objective of this six-week, examiner-blind clinical study was to assess the tooth whitening and extrinsic stain prevention efficacy of a new dentifrice delivering 1.0% hydrogen peroxide, 0.243% sodium fluoride, and sodium tripolyphosphate in a high-cleaning silica base (Test Dentifrice) relative to that of a commercially available hexametaphosphate-containing whitening dentifrice (Positive Control Dentifrice)., Methodology: Following a baseline oral soft tissue examination and scoring of extrinsic tooth stain and tooth shade, qualifying adult male and female subjects from the Mississauga, Ontario, Canada area were randomized into either the Test or Positive Control Dentifrice group. The two groups were balanced for age, tobacco use, extrinsic tooth stain, and tooth shade scores. All subjects received a dental prophylaxis, and were provided with a supply of their assigned product and a soft-bristled adult toothbrush for use at home. Subjects were instructed to brush their teeth for two minutes twice daily (morning and evening) using only the dentifrice provided, and to refrain from using any other oral hygiene products for the entire six weeks of the study. There were no restrictions regarding diet or smoking habits during the course of the study. Oral soft tissue, extrinsic tooth stain and tooth shade assessments for each subject were repeated after two and six weeks of product use. All statistical tests were two-sided and employed a level of significance of alpha = 0.05., Results: Seventy-six (76) subjects complied with the protocol and completed the entire study. At both the two-week and six-week examinations, the Test Dentifrice prevented statistically significant (p < 0.05) more tooth stain as compared to the Positive Control Dentifrice. Also, at the two-week and six-week examinations, the Test Dentifrice provided statistically significant (p < 0.05) greater tooth whitening as compared to the Positive Control Dentifrice (2.64 and 3.77 shade rank reductions, respectively)., Conclusion: A new whitening dentifrice, delivering 1.0% hydrogen peroxide, 0.243% sodium fluoride, and sodium tripolyphosphate in a high-cleaning silica base provides a statistically significant greater level of efficacy for both tooth whitening and prevention of extrinsic tooth stain than the commercially available Positive Control Dentifrice.

The objective of this double-blind clinical study, conducted in harmony with American Dental Association guidelines, was to compare a new dentifrice formulation variant of Colgate Total Toothpaste containing a special grade of silica (Colgate Total Plus Whitening Toothpaste) to the commercially available, ADA-Accepted and clinically proven Colgate Total Toothpaste for controlling breath odor twelve hours after brushing the teeth. Breath odor was evaluated by a panel of three examiners using a nine-point hedonic scale. Following a baseline evaluation of breath odor, prospective study subjects who scored above the threshold value for unpleasant breath odor were stratified by score and randomized into two treatment groups. Subjects were provided with a soft-bristled toothbrush, and brushed their teeth thoroughly in their regular and customary manner with their assigned dentifrice. Subjects refrained from dental hygiene, breath mints or mounthrinses for the next twelve hours, after which they were again evaluated for breath odor. Eighty-three (83) adult male and female subjects from the Mississauga, Ontario, Canada area participated in the study. At twelve hours after brushing their teeth, subjects in both dentifrice treatment groups presented mean breath odor scores which were statistically significantly lower than the mean scores observed at baseline. Importantly, there was no statistical difference between the two dentifrices of the mean twelve-hour breath odor scores. The mean twelve-hour breath scores for the Colgate Total Plus Whitening Toothpaste group and the Colgate Total Toothpaste group were 4.89 and 4.67, respectively, which are within the range of values corresponding to pleasant breath odor. Thus, the results of this double-blind clinical study, conducted according to a protocol which had been approved by the Council on Scientific Affairs of the American Dental Association, support the conclusion that Colgate Total Plus Whitening Toothpaste and Colgate Total Toothpaste provide effective control of breath odor at twelve hours after toothbrushing.

Background: The efficacy of an essential oil-containing antiseptic mouthrinse (Listerine Antiseptic, Pfizer) and an antiplaque/antigingivitis dentifrice (Colgate Total, Colgate-Palmolive) has been demonstrated in numerous double-blind clinical studies. This study was conducted to determine their comparative efficacy., Methods: Three hundred sixteen subjects with mild-to-moderate gingival inflammation and plaque received a dental prophylaxis and began their randomly assigned brushing and rinsing regimen in an unsupervised setting. Subjects brushed for one minute and rinsed with 20 milliliters for 30 seconds twice daily for six months. The three groups were L (control toothpaste/Listerine rinse), T (Colgate Total toothpaste/control rinse) and P (control toothpaste/control rinse)., Results: Subjects in the L and T groups demonstrated statistically significantly lower (P < .001) Modified Gingival Index, or MGI; Bleeding Index, or BI; and Plaque Index, or PI, at both three and six months than subjects in the P group. The magnitude of reduction for the L group was 22.9 percent, 70 percent and 56.1 percent, respectively, and for the T group, 20.8 percent, 58 percent and 22.1 percent, respectively. Subjects in the L group were not different from subjects in the T group in regard to visual signs of gingivitis (MGI), but were more effective (P < .001) than subjects in the T group in experiencing reduced BI and PI. No product-related adverse events were reported., Conclusion: Although the Listerine Antiseptic and Colgate Total antiplaque/antigingivitis products produced similar, clinically significant reductions in gingivitis (as measured by MGI and BI), Listerine, when used in conjunction with a fluoride dentifrice and usual oral hygiene, provided a greater benefit in reducing plaque., Clinical Implications: When considering an antiplaque/antigingivitis product to recommend to patients, clinicians should consider Listerine Antiseptic, in conjunction with usual oral hygiene, if more rigorous plaque control is desired.

The objective of this double-blind clinical study was to investigate the effectiveness of a dentifrice containing triclosan and a copolymer, Colgate Total Toothpaste, for controlling breath odor twelve hours after brushing the teeth compared to a placebo dentifrice which did not contain triclosan or a copolymer. Breath odor was evaluated by a panel of four expert judges using a nine-point hedonic scale. Following a baseline evaluation of breath odor, prospective study subjects who presented scores above the threshold value for unpleasant breath odor were stratified by score, and randomized into two treatment groups. Subjects were provided with a soft-bristled toothbrush, and brushed their teeth thoroughly in their regular and customary manner with their assigned dentifrice. Subjects refrained from dental hygiene, breath mints, or mouth rinses for the next twelve hours, after which they were once again evaluated for breath odor. Sixty-three (63) adult male and female subjects from the Mississauga, Ontario, Canada area participated in the study. At twelve hours after brushing their teeth, subjects in both dentifrice treatment groups presented mean breath odor scores which were statistically significantly lower than the mean scores observed at baseline. However, the difference between the mean twelve-hour breath odor scores differed significantly between the two dentifrices. The mean twelve-hour breath odor score for the Colgate Total Toothpaste group was 4.77, which is within the range of values corresponding to pleasant breath odor; the mean twelve-hour breath odor score for the placebo group was 6.05, which is above the value corresponding to unpleasant breath odor. Thus, the results of this double-blind clinical study support the conclusion that Colgate Total Toothpaste provides effective control of breath odor at twelve hours after brushing the teeth.
