Trial Outcomes & Findings for A Clinical Study to Evaluate the Anti-Sensitivity Efficacy of a Stannous Fluoride Toothpaste in a Population of Dentin Hypersensitivity Sufferers (NCT NCT06354270)

NCT ID: NCT06354270

Last Updated: 2025-06-25

Results Overview

Evaporative (air) sensitivity was assessed on facial surfaces of teeth by directing a 1 second application of air from standard dental syringe held perpendicular to tooth surface. Participant response to the stimulus was evaluated using the Schiff sensitivity scale, an examiner-based index, scored immediately following administration of the evaporative (air) stimulus. Score ranged from 0-3, where 0=Did not respond to air stimulation;1=Responded to air stimulus but did not request discontinuation of stimulus;2=Responded to air stimulus and requested discontinuation or moved from stimulus;3=Responded to stimulus, considered stimulus to be painful, requested discontinuation of the stimulus. Schiff sensitivity score=Mean score for the two 'Test Teeth' selected at Baseline by the examiner. Lower score=low degree of sensitivity. Change from Baseline was calculated by subtracting Baseline (Day 0) score from Day 56 score. A negative change from Baseline indicated improvement in sensitivity.

Participant Flow

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

A total of 119 participants were screened of which 115 participants were enrolled, and 113 participants were randomized to receive treatment in 2 groups: Test Toothpaste group (57 participants) and Reference Toothpaste group (56 participants). 6 participants were not randomized (4 participants did not meet the study criteria, 2 participants withdrew consent). A total of 112 randomized participants completed the study.

Tactile sensitivity of incisor, canine and pre-molar teeth was assessed using a constant pressure probe (Yeaple probe). The probe tip was placed perpendicular to the facial surface of tooth and drawn slowly across the exposed dentin. After each application of the stimulus, the participant was asked to indicate whether they experienced any pain or discomfort (yes/no response). The gram setting which elicited two consecutive 'yes' responses was recorded as the tactile threshold in gram for that tooth. 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. Higher tactile threshold indicated less sensitivity. Change from Baseline was calculated by subtracting Baseline (Day 0) value from Day 56 value. A positive change from Baseline indicated improvement in sensitivity.

The DHEQ is a condition-specific measure of Oral Health-Related Quality of Life (OHrQoL) used to investigate the impacts of tooth sensitivity on everyday life. DHEQ section 1, questions 7-9 were about participant's sensitive teeth and its impact on their 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). The total score for each question ranged from 1 to 10; where lower scores indicated less intense, less bothersome and tolerable sensations. Change from Baseline was calculated by subtracting the Baseline (Day 0) score from score at each indicated timepoint. A negative change from Baseline indicated improvement in sensitivity and its impact on everyday life.

The DHEQ is a condition-specific measure of OHrQoL used to investigate the impacts of tooth sensitivity on everyday life. Section 2 of DHEQ included 34 questions grouped into 5 separate domains: Restrictions(Q1-4), Adaptation(Q5-16), Social Impact(Q17-21), Emotional Impact(Q22-29), and Identity(Q30-34). Participants scored each question using a 7-point scale ranging from 1 to 7 where 1=strongly disagree, 2=disagree, 3=disagree a little, 4=neither agree nor disagree, 5=agree a little, 6=agree, and 7=strongly agree. The total score was derived from the sum of scores across all domains (Q1-34) and ranged from 34 to 238, where lower score indicated better OHrQoL. Change from Baseline was calculated by subtracting the Baseline (Day 0) score from the score at each indicated timepoint. A negative change from Baseline indicated improvement in OHrQoL.

Restrictions domain of DHEQ evaluated 'the ways in which any sensations in teeth affected participants in their daily life'. It included 4 questions each scored using a 7-point scale ranging from 1 to 7 where 1=strongly disagree, 2=disagree, 3=disagree a little, 4=neither agree nor disagree, 5=agree a little, 6=agree, and 7=strongly agree. Thus, the total score ranged from 4 to 28. Lower score indicated less effect of sensations on participant's daily life. Change from Baseline was calculated by subtracting the Baseline (Day 0) score from the score at each indicated timepoint. A negative change from Baseline indicated improvement (less effect of sensations on participant's daily life).

Global oral health was evaluated using a single question of DHEQ. Participants rated the overall health of their mouth, teeth, and gums using a 6-point scale ranging from 1 to 6 where 1=excellent, 2=very good, 3=good, 4=fair, 5=poor, and 6=very poor. Lower score indicated better oral health. Change from Baseline was calculated by subtracting the Baseline (Day 0) score from score at each indicated timepoint. A negative change from Baseline indicated improvement in overall oral health.

SECONDARY outcome

Timeframe: Baseline (Day 0), Day 28 and Day 56

Population: mITT population.

Effect on life overall was evaluated using 4 questions of DHEQ about how much the sensations in teeth affected participant's life overall. Participants scored each question on a 5-point scale ranging from 0 to 4 where 0=not at all, 1=a little, 2=somewhat; 3=quite a bit, and 4=very much. Thus, the total score ranged from 0 to 16, where lower score indicated less impact of sensations on participant's life overall. Change from Baseline was calculated by subtracting the Baseline (Day 0) score from score at each indicated timepoint. A negative change from Baseline indicated improvement (less impact of sensations on participant's life overall).
