Trial Outcomes & Findings for Clinical Study to Evaluate the Anti-sensitivity Efficacy of a Stannous Fluoride Toothpaste in a Population of Dentin Hypersensitivity Sufferers (NCT NCT06359028)

NCT ID: NCT06359028

Last Updated: 2025-06-24

Results Overview

Schiff sensitivity score was assessed by participant's response to an evaporative (air) stimulus after the stimulation of the 2 test teeth selected at Baseline by the examiner. Participant's response to the stimulus was evaluated by the examiner using the Schiff sensitivity scale immediately following administration of the evaporative air stimulus. Score ranged from 0-3, where 0=Does not respond to air stimulation; 1=Responds to air stimulus but does not request discontinuation of stimulus; 2=Responds to air stimulus and requests discontinuation or moves from stimulus; 3=Responds to stimulus, considers stimulus to be painful, requests discontinuation of the stimulus. Schiff sensitivity score = Mean score for the two 'Test Teeth' selected at baseline by the examiner. Change from baseline was calculated by subtracting baseline score from Day 56 score. A decrease in Schiff sensitivity score indicated an improvement.

Participant Flow

This study was conducted at a single center in the United States.

Measure
Test Toothpaste
Participants were instructed to dose the toothbrush with a ribbon of test toothpaste, across the full brush head and to brush the entire dentition thoroughly for at least 1-timed minute, twice daily (morning and evening), for approximately 56 days making sure to brush the sensitive areas of the two 'test teeth' carefully first. Participants who wished to rinse after brushing were instructed to rinse with 10 milliliter (ml) water using the graduated rinsing cup provided.
Reference Toothpaste (Negative Control)
Participants were instructed to dose the toothbrush with a ribbon of reference toothpaste, across the full brush head and to brush the entire dentition thoroughly for at least 1-timed minute, twice daily (morning and evening) for approximately 56 days. Participants who wished to rinse after brushing were instructed to rinse with 10 ml water using the graduated rinsing cup provided.

PRIMARY outcome

Timeframe: Baseline and Day 56

Population: Modified Intent-To-Treat (mITT) population included all randomized participants who received at least one dose of investigational product and completed at least one-post Baseline dentin hypersensitivity (DH) efficacy assessment. Only those participants with data available at the specified time points were analyzed.

Schiff sensitivity score was assessed by participant's response to an evaporative (air) stimulus after the stimulation of the 2 test teeth selected at Baseline by the examiner. Participant's response to the stimulus was evaluated by the examiner using the Schiff sensitivity scale immediately following administration of the evaporative air stimulus. Score ranged from 0-3, where 0=Does not respond to air stimulation; 1=Responds to air stimulus but does not request discontinuation of stimulus; 2=Responds to air stimulus and requests discontinuation or moves from stimulus; 3=Responds to stimulus, considers stimulus to be painful, requests discontinuation of the stimulus. Schiff sensitivity score = Mean score for the two 'Test Teeth' selected at baseline by the examiner. Change from baseline was calculated by subtracting baseline score from Day 56 score. A decrease in Schiff sensitivity score indicated an improvement.

Timeframe: Baseline and Day 56

Population: mITT Population. Only those participants with data available at the specified time points were analyzed.

Tactile sensitivity was assessed by participant's response to tactile stimulus after the stimulation of the 2 test teeth selected at Baseline by the examiner. A constant pressure probe (Yeaple probe) was used for stimulation. The probe tip was placed perpendicular to the facial surface of tooth and drawn slowly across the exposed dentine. After each application, the participants were asked to indicate whether they experienced any pain or discomfort (yes/no response). The pressure setting with two consecutive 'yes' responses was recorded as the tactile threshold in gram (g). At baseline, the upper force setting was 20g. Tactile threshold (g) was derived as the mean value for the two 'Test Teeth' selected by the examiner at baseline. An increase in tactile threshold indicated an improvement in sensitivity. Change from baseline was calculated by subtracting baseline value from Day 56 value.

Population: mITT Population. Only those participants with data available at the specified time points were analyzed.

DHEQ section 1, questions 7-9 were about teeth sensation and its impact on everyday life. Participants scored Q7 (how intense are the sensations?) on a scale of 1 (not at all intense) to 10 (worst imaginable); Q8 (how bothered are you by any sensations?) on a scale of 1 (not at all bothered) to 10 (extremely bothered); Q9 (how well can you tolerate sensations?) on a scale of 1 (can easily tolerate) to 10 (can't tolerate at all). Thus, the total score ranged from 3 to 30; where the lower score indicated less sensitivity and less impact on everyday life. Change from baseline was calculated as score at indicated post-baseline timepoints minus score at baseline.

The DHEQ was a condition-specific measure of Oral Health-related Quality of Life (OHrQoL) in relation to DH which consisted of a total of 34 questions in section 2 grouped into 5 separate domains: Restrictions(Q1-4), Adaptation(Q5-16), Social Impact(Q17-21), Emotional Impact(Q22-29), and Identity(Q30-34), each scored using a 7-point scale ranging from 1 (strongly disagree) to 7 (strongly agree). Thus, the total score ranged from 34 to 238; where the lower score indicated improvement in the symptoms. Change from baseline was calculated as score at indicated post-baseline timepoints minus score at baseline.

SECONDARY outcome

Timeframe: Baseline, Day 28 and Day 56

Population: mITT Population. Only those participants with data available at the specified time points were analyzed.

Effect on life was evaluated using 4 questions which asked how much the sensations in teeth affected participant's life overall. The scale ranged from 0 (not at all) to 4 (Very much) and thus, the total score ranged from 0 to 16; where the lower score indicated improvement in the symptoms. Change from baseline was calculated as score at indicated post-baseline timepoint minus score at baseline.
