Brief summary

The objective of this clinical research study is to assess the efficacy of three oral hygiene multi-component regimens encompassing the use of a manual toothbrush, toothpaste and a mouthwash in controlling established dental plaque and gingivitis.

Interventions

DRUGtriclosan/fluoride toothpaste + cetylpyridinium chloride Mouthwash

Brush whole mouth with Total toothpaste for 1 minute, 2 times/day for 6 weeks (study duration) using a Total 360 toothbrush. Immediately after each toothbrushing, rinse whole mouth with 20 ml of mouthwash for 30 seconds.

DRUGstannous fluoride toothpaste + cetylpyridinium chloride Mouthwash

Brush whole mouth with Crest Pro-Health toothpaste for 1 minute, 2 times/day for 6 weeks (study duration) using an Oral B Pro-Health toothbrush. Immediately after each toothbrushing, rinse whole mouth with 20 ml of Crest Pro-Health Multi-Protection mouthwash for 30 seconds.

DRUGfluoride toothpaste + fluoride Mouthwash

Brush whole mouth with Crest Cavity Protection toothpaste for 1 minute, 2 times/day for 6 weeks (study duration) using an Oral B Indicator toothbrush. Immediately after each toothbrushing, rinse whole mouth with 20 ml of Crest Pro-Health For Me Breezy Mint mouthwash for 30 seconds.
