Dentin Sensitivity
Conditions
Brief summary
The aim of this study is to confirm the clinical dentin hypersensitivity (DH) efficacy of a 5 percent (%) calcium sodium phosphosilicate (CSPS) toothpaste.
Detailed description
This will be a single center, 8-week, randomized, controlled, examiner-blind, 2-treatment arm, parallel design, stratified (by maximum baseline Schiff sensitivity score of the two selected 'test teeth') clinical study to evaluate the anti-sensitivity efficacy of a 5% CSPS toothpaste in a DH population. The clinical efficacy of the 5% CSPS toothpaste (test toothpaste) will be compared with that of a reference toothpaste, a commercially available, regular fluoride toothpaste with no known anti-sensitivity properties (negative control). Sufficient participants will be screened to randomize approximately 234 participants to investigational product (approximately 117 per treatment group) and to ensure approximately 210 evaluable participants complete the entire study (approximately 105 per treatment group).

| Measure | Time frame | Description |
|---|---|---|
| Adjusted Mean Change From Baseline in Schiff Sensitivity Score at Day 56 | Baseline (Day 0) and Day 56 | 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. |

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 2 'Test Teeth' selected at Baseline by examiner. Lower score=low degree of sensitivity. 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. |
| Adjusted Mean Change From Baseline in Tactile Threshold (g) at Days 3, 7, 14 and 28 | Baseline (Day 0), Days 3, 7, 14 and 28 | 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. |
| Adjusted Mean Change From Baseline in Impact on Everyday Life (Section 1 of Dentin Hypersensitivity Experience Questionnaire [DHEQ-48], Question [Q]7-9) at Days 28 and 56 | Baseline (Day 0), Day 28 and Day 56 | 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. |

Outcome results
Primary
Adjusted Mean Change From Baseline in Schiff Sensitivity Score at Day 56
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.

Adjusted Mean Change From Baseline in Tactile Threshold (g) at Days 3, 7, 14 and 28
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.
