Clinical Study Comparing Dental Plaque and Gingivitis Reduction After Using One of Three Oral Hygiene Multi-component Regimens (Using of a Manual Toothbrush, a Toothpaste and a Mouthwash)

Clinical Efficacy in Reducing Established Dental Plaque and Gingivitis of a Toothpaste Containing 0.3% Triclosan, 2% Copolymer / Sodium Fluoride and a Manual Toothbrush as Compared to an Oral Hygiene Multi-component Regimen Encompassing the Use of a Manual Toothbrush, a Toothpaste Containing Stannous Fluoride / Sodium Hexametaphosphate and a Mouthwash Containing 0.07% Cetylpyridinium Chloride

Dental Plaque, Gingivitis

Brief summary

The objective of this clinical research study is to assess the efficacy of a commercially available triclosan/copolymer toothpaste compared to a commercially available oral hygiene multi-component regimen encompassing the use of a manual toothbrush, a toothpaste containing stannous fluoride / sodium hexametaphosphate and a mouthwash containing cetylpyridinium chloride relative to a negative control regimen in reducing established dental plaque and gingivitis over three and six months of assigned product use.

Interventions

Brush whole mouth with Total toothpaste (triclosan/fluoride) using Total 360 toothbrush for 1 minute, 2 times/day for 6 months (study duration).

Brush whole mouth with Crest Pro-Health toothpaste using an Oral B Pro-Health toothbrush for 1 minute, 2 times/day for 6 months (study duration).

DRUGfluoride only toothpaste

Brush whole mouth with Crest Cavity Protection toothpaste using an Oral B Indicator toothbrush for 1 minute, 2 times/day for 6 months (study duration). Immediately after each brushing, rinse whole mouth with 20 ml of Crest fluoride Mouthwash for 30 seconds.

Immediately after each brushing with Crest Pro-Health toothpaste, rinse whole mouth with 20 ml of Crest Pro-Health Mouthwash for 30 seconds.

DRUGFluoride only mouthwash

Immediately after each brushing with Crest Cavity Protection toothpaste, rinse whole mouth with 20 ml of Crest Pro-Health For Me mouthwash for 30 seconds.
