Trial Outcomes & Findings for Exploratory Clinical Study to Investigate the Ability of an Experimental Combination Dentifrice to Protect Sensitive Teeth (NCT NCT05243745)
NCT ID: NCT05243745
Last Updated: 2024-09-20
Results Overview
Evaporative (air) sensitivity was assessed on facial surfaces of eligible incisor,canine and pre-molar teeth by directing a 1 second application of air from standard dental syringe held perpendicular to tooth surface,approximately 1-2 millimeter(mm) coronal to gingival margin from a distance of approximately 1 centimeter(cm). Participant response to the stimulus was evaluated using the Schiff sensitivity scale, an examiner-based index scored immediately following administration of the evaporative stimulus. Score ranged from 0-3; 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 stimulus. A decrease in Schiff sensitivity score indicated an improvement in sensitivity. Mean was calculated once by selecting 2 test teeth located in different quadrants of mouth.

Participant Flow
The study was conducted at a single center in the United Kingdom.
A total of 133 participants were screened of which 120 participants were randomized to a treatment with either one of the 4 products: test product (combination toothpaste of 3 percent \[%\] methyl vinyl ether/maleic anhydride co-polymer \[PVM/MA\] + 5% Potassium Nitrate \[KNO3\]), comparator 1 (toothpaste containing 3% PVM/MA), comparator 2 (toothpaste containing 5% KNO3), or negative control (a regular fluoride toothpaste).

PRIMARY outcome
Timeframe: Baseline (Day 0)Population: The mITT population.
Tactile sensitivity was assessed for eligible incisor, canine and pre-molar teeth 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 participant was asked to indicate whether they experienced any pain or discomfort (yes/no response). The pressure setting at which participant gave two consecutive 'yes' responses was recorded as the tactile threshold (grams \[g\]). At Baseline, the maximum force was 20 g; at all subsequent visits, 80 g. If no sensitivity was found at the upper limit, the tactile threshold was recorded as greater than (\>) 20 g (baseline) or \>80 g (all other visits). An increase in tactile threshold indicated an improvement. Mean was calculated once by selecting two test teeth which were located in different quadrants of mouth.

PRIMARY outcome
Timeframe: Day 14Population: The mITT population. Here, overall number analyzed is the number of participants with data available for analyses for this outcome measure.
Tactile sensitivity was assessed for eligible incisor, canine and pre-molar teeth 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 participant was asked to indicate whether they experienced any pain or discomfort (yes/no response). The pressure setting at which participant gave two consecutive 'yes' responses was recorded as the tactile threshold (g). At Baseline, the maximum force was 20 g; at all subsequent visits, 80 g. If no sensitivity was found at the upper limit, the tactile threshold was recorded as \>20 g (baseline) or \>80 g (all other visits). An increase in tactile threshold indicated an improvement. Mean was calculated once by selecting two test teeth which were located in different quadrants of mouth.

Timeframe: Baseline (Day 0), Days 3, 14, 28 and 56Population: The mITT population. Only those participants available at the indicated timepoints were analyzed.
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,approximately 1-2 mm coronal to gingival margin from approximately 1 cm. Participant response to stimulus was evaluated using the Schiff sensitivity scale, an examiner-based index scored immediately following administration of the evaporative stimulus. Score ranged from 0-3;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 stimulus. A decrease in Schiff sensitivity score indicated an improvement in sensitivity. Change from Baseline was calculated by subtracting the Baseline value from the value at each indicated timepoint. A negative change from Baseline indicated an improvement.

Timeframe: Baseline (Day 0), Days 3, 14, 28 and 56Population: The mITT population. Only those participants available at the indicated timepoints were analyzed.
Tactile sensitivity was assessed for teeth 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 participant was asked to indicate whether they experienced any pain or discomfort (yes/no response). The pressure setting at which participant gave two consecutive 'yes' responses was recorded as the tactile threshold (g). At Baseline, the maximum force was 20 g; at all subsequent visits, 80 g. If no sensitivity was found at the upper limit, the tactile threshold was recorded as \>20 g (baseline) or \>80 g (all other visits). An increase in tactile threshold indicated an improvement. Change from Baseline was calculated by subtracting the Baseline value from the value at each indicated timepoint. A positive change from Baseline indicated an improvement.

SECONDARY outcome
Timeframe: Baseline (Day 0), Days 3, 14, 28 and 56Population: The mITT population. Only those participants available at the indicated timepoints were analyzed.
The DHEQ was a validated, condition-specific measure of the impacts of tooth sensitivity on everyday life. It consisted of two sections. Section 1 included 9 questions about participant's sensitive teeth and the impact it has on participant's everyday life. All participants scored question number 7 to 9. Question (Q)7 (On a scale of 1 to 10 how intense are the sensations) was scored from 1=not at all intense to 10=worst imaginable; Q8 (On a scale of 1 to 10 how bothered are you by any sensations?) was scored from 1=not at all bothered to 10=extremely bothered; Q9 (On a scale of 1 to 10 how well you can tolerate the sensations?) was scored from 1=can easily tolerate to 10=can't tolerate at all. Change from Baseline was calculated by subtracting the Baseline value from the value at each indicated timepoint. A negative change from Baseline indicated an improvement (less impact of tooth sensitivity on participant's everyday life).

SECONDARY outcome
Timeframe: Baseline (Day 0), Days 3, 14, 28 and 56Population: The mITT population. Only those participants available at the indicated timepoints were analyzed.
DHEQ was a validated, condition-specific measure of the impacts of tooth sensitivity on everyday life. It consisted of 2 sections. Section 2 included 15 questions about the ways in which sensations in participant's teeth affected them in their daily life. Questions were grouped into the following domains: Restrictions(Q1-3), Adaptation(Q4-6), Social Impact(Q7-9), Emotional Impact(Q10-12), and Identity(Q13-15). All participants scored 15 questions using a 7-point scale, where 7=Strongly agree, 6=Agree, 5=Agree a little, 4=neither agree or disagree, 3=disagree a little, 2=disagree, and 1=strongly disagree. Total score was derived from the sum of scores in single domains and ranged from 15 to 105. Lower score indicated less effect of sensations on participant's daily life. Change from Baseline was calculated by subtracting Baseline value from value at each indicated timepoint. A negative change from Baseline indicated improvement (less impact of sensations on participant's daily life).

DHEQ was a validated, condition-specific measure of the impacts of tooth sensitivity on everyday life. It consisted of 2 sections. Restriction domain(Q1 to 3) of Section 2 consisted of following questions: Q1:Having sensation in my teeth takes a lot of the pleasure out of eating and drinking; Q2:It takes a long time to finish some foods and drinks because of sensations in my teeth; Q3:There have been times when I have had problems eating ice cream because of these sensations. All participants scored Q1 to 3 using a 7-point scale, where 7=Strongly agree, 6=Agree, 5=Agree a little, 4=neither agree or disagree, 3=disagree a little, 2=disagree, and 1=strongly disagree. Total score ranged from 3 to 21. Lower score indicated less effect of sensations on participant's daily life.

SECONDARY outcome
Timeframe: Baseline (Day 0), Days 3, 14, 28 and 56Population: The mITT population. Only those participants available at the indicated timepoints were analyzed.
DHEQ was a validated, condition-specific measure of the impacts of tooth sensitivity on everyday life. It consisted of 2 sections. Social Impact domain(Q7 to 9) of Section 2 consisted of following questions: Q7:Because of sensations I take longer than others to finish meal; Q8:I have to be careful what I eat when I am with others because of sensation in my teeth; Q9:Going to dentist is hard for me because I know it is going to be painful as a result of sensations in my teeth. All participants scored Q7 to 9 using a 7-point scale, where 7=Strongly agree, 6=Agree, 5=Agree a little, 4=neither agree or disagree, 3=disagree a little, 2=disagree, and 1=strongly disagree. Total score ranged from 3 to 21. Lower score indicated less effect of sensations on participant's daily life. Change from Baseline was calculated by subtracting Baseline value from value at each indicated timepoint. A negative change from Baseline indicated improvement(less impact of sensations on participant's daily life).
