研究概览
简要总结
This study will evaluate the effectiveness of an experimental dentifrice containing stannous fluoride, an established dentine tubule occlusion technology, at reducing dentine hypersensitivity (DH) compared to a negative control dentifrice. The test and control dentifrices will be administered for a total of 8 weeks, with assessments (via evaporative air and tactile stimuli) at baseline, and after 4 and 8 weeks twice-daily use.
详细描述
This single centre, randomized, controlled, examiner-blind, 2 treatment arm, parallel group design study, stratified by maximum baseline Schiff sensitivity score (of the two selected teeth), with a treatment period of 8 weeks will investigate the clinical effectiveness of an experimental stannous fluoride dentifrice in the reduction of DH. DH will be assessed at Baseline, and after 4 and 8 weeks treatment to monitor clinical efficacy and safety.

研究组 & 干预措施
Test Dentifrice: Stannous fluoride (SnF2)
Participants were instructed to apply a strip of dentifrice containing 0.454% stannous fluoride (SnF2) and 0.072% sodium fluoride (NaF) (1450 parts per million [ppm] fluoride in total) to cover the head of the toothbrush and brush their teeth for 1 timed minute, twice daily (morning and evening), following their normal routine. Participants were also permitted to rinse with tap water.
干预措施: Stannous fluoride (SnF2) (Other)
Negative Control Dentifrice: Sodium monofluorophosphate (SMFP)
Participants were instructed to apply a strip of dentifrice containing 1400ppm fluoride as sodium monofluorophosphate (SMFP) to cover the head of the toothbrush and brush their teeth for 1 timed minute, twice daily (morning and evening), following their normal routine. Participants were also permitted to rinse with tap water.
干预措施: Sodium monofluorophosphate (SMFP) (Other)
结局指标
主要结局
Change From Baseline in Schiff Sensitivity Score at Week 8
时间窗: At Baseline and Week 8
The examiner assessed the participant's response to the evaporative air stimulus, after the stimulation of each individual tooth, using the Schiff Sensitivity Scale as follows: 0 Participant does not respond to air stimulation, 1 Participant responds to air stimulus but does not request discontinuation of stimulus, 2 Participant responds to air stimulus and requests discontinuation or moves from stimulus, 3 Participant responds to stimulus, considers stimulus to be painful and requests discontinuation of the stimulus. A reduction in Schiff Sensitivity score indicate improvement in sensitivity.
次要结局
- Change From Baseline in Schiff Sensitivity Score at Week 4(At Baseline and Week 4)
- Change From Baseline in Tactile Threshold at Week 4 and 8(At Baseline, Week 4 and Week 8)
