Trial Outcomes & Findings for A Clinical Trial to Test the Effect of a Marketed Mouth Rinse on Stain Removal (NCT NCT02151058)

NCT ID: NCT02151058

Last Updated: 2015-06-01

Results Overview

Tooth stain surface and stain intensity were assessed by using scores on the Lobene Stain Index (two part visual scale), scored 0 - 3. Where 0 = no stain, 1 = light stain, 2 = moderate stain and 3 = heavy stain. The second part of the scale examined the surface of the tooth on a scale of 0-3, where 0= no stain, 1 = covering up to 1/3 of the region, 2 = covering \> 1/3 to 2/3 of the region and 3 = covering \> 2/3 of the region. The mean composite score (0-9) was determined by multiplying the individual tooth stain surface and stain intensity scores and summing then dividing by the number of regions scored for the subject (or tooth).

PRIMARY outcome

Timeframe: 15 Days

Population: Analysis was based on the Full Analysis Set, which included all randomized subjects who used study product and had baseline and at least one post-baseline efficacy assessment.

Tooth stain surface and stain intensity were assessed by using scores on the Lobene Stain Index (two part visual scale), scored 0 - 3. Where 0 = no stain, 1 = light stain, 2 = moderate stain and 3 = heavy stain. The second part of the scale examined the surface of the tooth on a scale of 0-3, where 0= no stain, 1 = covering up to 1/3 of the region, 2 = covering \> 1/3 to 2/3 of the region and 3 = covering \> 2/3 of the region. The mean composite score (0-9) was determined by multiplying the individual tooth stain surface and stain intensity scores and summing then dividing by the number of regions scored for the subject (or tooth).
