Trial Outcomes & Findings for Test on a New Experimental Mouth Rinse for Relieving Tooth Sensitivity (NCT NCT02113579)

NCT ID: NCT02113579

Last Updated: 2015-06-10

Results Overview

Tooth sensitivity was measured using a Cold Air Stimulus. When being assessed, participants rated their perception of the pain/discomfort experienced when cold air was directed at the exposed root of each tooth by marking a single vertical line on a Visual Analogue Scale (VAS) scale from 0 to 100 mm, where 0 = No Pain/Discomfort and 100 = Intense Pain/Discomfort. The dental recorder measured the length of the line from 0 to the participant's line and recorded the VAS score in mm. The score for each participant was calculated by averaging the scores for all study teeth for that participant. A participant was considered an individual success if the participant's mean cold air stimulus VAS score at Week 4 was at least 30% lower than the participant's mean baseline cold air stimulus VAS score.

PRIMARY outcome

Timeframe: 4 Weeks

Population: Analysis was based on Full Analysis Set, which included all randomized subjects.

Tooth sensitivity was measured using a Cold Air Stimulus. When being assessed, participants rated their perception of the pain/discomfort experienced when cold air was directed at the exposed root of each tooth by marking a single vertical line on a Visual Analogue Scale (VAS) scale from 0 to 100 mm, where 0 = No Pain/Discomfort and 100 = Intense Pain/Discomfort. The dental recorder measured the length of the line from 0 to the participant's line and recorded the VAS score in mm. The score for each participant was calculated by averaging the scores for all study teeth for that participant. A participant was considered an individual success if the participant's mean cold air stimulus VAS score at Week 4 was at least 30% lower than the participant's mean baseline cold air stimulus VAS score.

SECONDARY outcome

Timeframe: 4 Weeks

Population: Analysis was based on the Full Analysis Set, which included all randomized subjects.

Tooth sensitivity was measured using a Yeaple probe. The force at which discomfort was felt by the participant was recorded on a scale of 10-80 grams. The score for each participant was calculated by averaging the scores for all study teeth for that participant, at each visit.

At each visit, participants rated their perception of the pain/discomfort experienced from the Yeaple probe by marking a single vertical line on a VAS scale from 0 to 100 mm, where 0 = No Pain/Discomfort and 100 = Intense Pain/Discomfort. The dental recorder measured the length of the line from 0 to the participant's line and recorded the VAS score in mm. The investigator recorded a VAS score of 0 mm for participants who did not experience discomfort at the maximum force of 80 grams. The score for each participant was calculated by averaging the scores for all study teeth for that participant.

At each visit, participants rated their perception of the pain/discomfort experienced by marking a single vertical line on a Visual Analogue Scale (VAS) scale from 0 to 100 mm, where 0 = No Pain/Discomfort and 100 = Intense Pain/Discomfort. Participants were instructed as follows:"Please rate the intensity of the pain/discomfort you have experienced in the last two weeks when drinking cold/hot beverages and/or foods, eating sweet and sour foods, breathing cold air, brushing your teeth or performing any habits/behaviors that elicit your dentinal hypersensitivity pain/discomfort since you have been using the product." The dental recorder measured the length of the line from 0 to the participant's line and recorded the VAS score in mm.
