Change From Baseline in Tactile Threshold at Days 3, 14, 28 and 56Baseline (Day 0), Days 3, 14, 28 and 56Tactile 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.

Participants were dosed by the toothbrush provided with a strip of dentifrice (a full brush head) on each brushing occasion. Negative control was a regular fluoride toothpaste. Participants were instructed to brush their two selected 'test teeth' first, followed by the whole mouth for one timed minute, twice daily (morning and evening) for 8 weeks. Participants were permitted to rinse with water post-brushing.

Mean Schiff Sensitivity Score (Average of the Two Selected Test Teeth) at Baseline (Day 0)

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.

Time frame: Baseline (Day 0)

Population: The modified intent-to-treat (mITT) population included all randomized participants who completed at least one use of study product and had at least one post-baseline clinical performance assessment (Schiff sensitivity assessment or Tactile sensitivity assessment).

Mean Tactile Threshold (Average of the Two Selected Test Teeth) at Baseline (Day 0)

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.

Change From Baseline in DHEQ Adaptation Domain Score (Section 2 Questions 4 to 6) at Days 3, 14, 28 and 56

DHEQ was a validated, condition-specific measure of the impacts of tooth sensitivity on everyday life. It consisted of 2 sections. Adaptation domain (Q4 to 6) of Section 2 consisted of following questions: Q4: I have to change the way I eat or drink certain things; Q5: I have to be careful how I breathe on a cold day; Q6: When eating some foods, I have made sure they don't touch certain teeth. All participants scored Q4 to 6 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 the Baseline value from the value at each indicated timepoint. A negative change from Baseline indicated improvement (less impact of sensations on participant's daily life).

Time frame: Baseline (Day 0), Days 3, 14, 28 and 56

Population: The mITT population. Only those participants available at the indicated timepoints were analyzed.

Emotional Impact domain (Q10 to 12) of Section 2 consisted of following questions: Q10: I have been anxious that something I eat, or drink might cause sensations in my teeth; Q11: The sensations in my teeth have been irritating; Q12: The sensations in my teeth have been annoying. All participants scored Q10 to 12 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 the Baseline value from the value at each indicated timepoint. A negative change from Baseline indicated improvement (less impact of sensations on participant's daily life).

Time frame: Baseline (Day 0), Days 3, 14, 28 and 56

Population: The mITT population. Only those participants available at the indicated timepoints were analyzed.

Change From Baseline in DHEQ Total Score (Section 2 Questions 1-15) at Days 3, 14, 28 and 56

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).

Change From Baseline in Mean NRS Score at Days 3, 14, 28 and 56

The NRS was a segmented numeric version of the VAS in which a participant selected a number from 0 to 10 that best reflected the intensity of the discomfort caused by sensitivity in their teeth, where 0=no discomfort and 10=worst discomfort imaginable. Lower score indicated less discomfort caused by the sensitivity. Change from Baseline was calculated by subtracting the Baseline value from the value at each indicated timepoint. A negative change from Baseline indicated improvement (reduction in discomfort caused by sensitivity).

Time frame: Baseline (Day 0), Days 3, 14, 28 and 56

Population: The mITT population. Only those participants available at the indicated timepoints were analyzed.

Change From Baseline in Mean Score of Dentine Hypersensitivity Experience Questionnaire (DHEQ) (Section 1 Questions 7-9) at Days 3, 14, 28 and 56

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).

Time frame: Baseline (Day 0), Days 3, 14, 28 and 56

Change From Baseline in Schiff Sensitivity Score at Days 3, 14, 28 and 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,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.

Time frame: Baseline (Day 0), Days 3, 14, 28 and 56

Population: The mITT population. Only those participants available at the indicated timepoints were analyzed.

Change From Baseline in Tactile Threshold at Days 3, 14, 28 and 56

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.

Time frame: Baseline (Day 0), Days 3, 14, 28 and 56

Population: The mITT population. Only those participants available at the indicated timepoints were analyzed.

Mean Numeric Rating Scale (NRS) Score at Baseline, Days 3, 14, 28 and 56

The NRS was a segmented numeric version of the visual analog scale (VAS) in which a participant selected a number from 0 to 10 that best reflected the intensity of the discomfort caused by sensitivity in their teeth, where 0=no discomfort and 10=worst discomfort imaginable. Lower score indicated less discomfort caused by the sensitivity.

Time frame: Baseline (Day 0), Days 3, 14, 28 and 56

Population: The mITT population. Only those participants available at the indicated timepoints were analyzed.
