Trial Outcomes & Findings for A Clinical Study to Evaluate the Anti-Sensitivity Effect of a Calcium Sodium Phosphosilicate Toothpaste in a Population of Dentin Hypersensitivity Sufferers (NCT NCT06378008)

NCT ID: NCT06378008

Last Updated: 2025-09-08

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's 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 (Day 0) was calculated by subtracting Baseline score from Day 56 score. A negative change from Baseline indicated improvement.

PRIMARY outcome

Timeframe: Baseline (Day 0) and Day 56

Population: mITT population included all randomized participants who received at least one dose of investigational product and completed at least one-post Baseline DH efficacy assessment.

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's 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 (Day 0) was calculated by subtracting Baseline score from Day 56 score. A negative change from Baseline indicated improvement.

Tactile sensitivity was assessed for the 2 test teeth selected at Baseline by the examiner 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 dentine. After each application, the participants were asked to indicate whether they experienced any pain or discomfort (yes/no response). The gram setting with two consecutive 'yes' responses was recorded as the tactile threshold in gram for that tooth. At Baseline, the upper force setting was 20 g. Tactile threshold (g) was derived as the mean value for the 2 'Test Teeth' selected at Baseline by the examiner. 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.

The DHEQ is a validated, condition-specific measure of Oral Health-Related Quality of Life (OHRQoL) in relation to DH. 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 score 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.

DHEQ is a validated, condition-specific measure of OHRQoL in relation to DH. Section 2 of DHEQ included 34 questions grouped into 5 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 as sum of all questions (Q1 to Q34) score 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.

Identity domain of DHEQ evaluated what the sensations in participant's teeth meant for them. It included 5 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 5 to 35, where lower score indicated less impact of sensations on participant's identity. 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.

Test Toothpaste (CSPS Toothpaste)
n=107 Participants
Participants were instructed to apply a ribbon of Test toothpaste (Toothpaste containing 5% w/w CSPS and 1040 ppm fluoride as sodium monofluorophosphate) and 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 2 'Test teeth' carefully first.
Reference Toothpaste (Regular Fluoride Toothpaste)
n=108 Participants
Participants were instructed to apply a ribbon of Reference toothpaste (Regular fluoride toothpaste containing 1100 ppm fluoride as sodium fluoride) and brush the entire dentition thoroughly for at least 1-timed minute, twice-daily (morning and evening) for approximately 56 days.

Global Oral Health was evaluated using a single question of DHEQ about overall health of participant's mouth, teeth, and gums. 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.

Population: mITT Population.

Effect on Life was evaluated using 4 questions 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
