Conditions

Dental Plaque, Gingivitis

Brief summary

The objective of this randomized, single center, parallel clinical research study is to evaluate the comparative efficacy performance of three dentifrices -Colgate Total Toothpaste, Parodontax Toothpaste and Colgate Cavity Protection Toothpaste in controlling gingivitis and dental plaque in adults.

Interventions

0.76% monofluorophosphate (1000 ppm MFP), Colgate Cavity Protection toothpaste is a control treatment.

0.32% sodium fluoride (1450 ppm NaF) and 0.3% triclosan. Colgate Total toothpaste is the active comparator toothpaste

DRUGParodontax toothpaste

1400 ppm sodium fluoride (NaF), Parodontax toothpaste is the active comparator toothpaste
