Status Completed

Clinical Trial Summary

The purpose of this Study is to assess the efficacy of two ClōSYS Oral Rinse products in human subjects in controlling oral malodor in partial fulfillment of the requirements for American Dental Association's (ADA) requirement for obtaining ADA Seal for malodor.

Clinical Trial Description

Study Design:

The products used in the study are: ClōSYS Alcohol-Free Oral Rinse (also referred as ClōSYS Unflavored Oral Rinse) and ClōSYS justRIGHT MILD MINT Oral Rinse (also referred as ClōSYS Flavored Oral Rinse or Gentle Mint Flavored Oral Rinse). This is an in-vivo, eight-week, a single-center, randomized, double-blind (subject/investigator), 2-way cross-over design clinical study. There are two independent groups. Each subject of each group gets crossed over to the other sub-group within a same group after the washout period. Each group has their own control group. In the first phase, 25 subjects (50%) of each group are randomly assigned to the active group; the other 25 subjects are assigned to the control group. In the second phase, the participants will be crossed over within sub-group assignment. The Study enrolled 100 subjects, aged 21 to 65 years, with a slight to strong intrinsic oral malodor, as determined by a panel of trained odor judges calibrated and standardized using a range of standard odorants sufficient to reflect the different patterns of nose receptors.

Study Plan:

Subjects will receive verbal and written oral hygiene instructions, and either one bottle (16 oz. each) of ClōSYS Unflavored Oral Rinse, ClōSYS Flavored Oral Rinse- or Placebo Oral Rinse each week. Subjects will also receive measuring cups for dispensing the rinse and a diary log for recording usage (the Oral Hygiene Kit) for use during the treatment. After a 2-week wash out period, each subject will receive another bottle of oral rinse according to their group assignment.

Subjects will be instructed to rinse twice a day, each in the morning and in the evening, with 15 mL mouth rinse for 30 seconds. They will note in their patient's log the date and time of rinsing.

Subjects will be instructed to continue with their normal oral hygiene practices, including tooth brushing but omitting any use of oral rinses or mouthwashes except for the Study materials. The subjects also will be instructed not to use other non-study related products such as breath mints, lozenge, gums, etc. as well as refraining from elective dental procedures during the study period. ;
