About

This study will test the idea that using an experimental mouth rinse after each time you brush your teeth will result in a healthier mouth than using the regular mouth rinse. Participants will be expected to avoid oral hygiene (like brushing teeth or using mouthwash) for at least 12 hours before each visit and will not be allowed to eat, drink or smoke for at least 4 hours before each visit.

At the first visit, the study will be explained to you in detail and you will be allowed to ask any questions you may have before signing a consent form. You will complete a medical/dental history and the dentist will examine your mouth, during which he will poke your gums and scrape some plaque off your teeth for testing. If you do not meet the requirements to continue in the trial, you will be told that you do not need to return for more testing.

If you meet requirements to continue, you will have an equal chance of being assigned to use either of the two mouth rinses being studied. You will be given a diary, toothbrush, toothpaste, and your assigned mouth rinse, with instructions on how they must be used.

You will be instructed not to use any unassigned oral care products and to follow your usual eating habits. You will be given appointments to return two times within the next four weeks. At those visits, the staff will check to make sure you're following the instructions and ask how you're feeling, and the dentist will do the same thing he did during the first visit.

Full description

The primary objective of this randomized, double-blind, single-center, controlled, parallel-designed clinical study is to determine the efficacy of an experimental mouth rinse on whole-mouth mean plaque and gingivitis scores as an adjunct to brushing after four weeks of use.

The secondary objectives will be to determine the efficacy of the an experimental mouth rinse as an adjunct to brushing on whole-mouth mean plaque and gingivitis measured at 2 weeks as well as a bleeding assessment according to the Bleeding Index at 2 and 4 weeks. A microbiological assessment will be performed to identify and quantify specific oral microbes to assess any change in population.
