Conditions: Dentin Sensitivity
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 115
Healthy volunteers: yes

Brief summary:
The aim of this study is to confirm the clinical Dentin Hypersensitivity (DH) efficacy of a 0.454 percent (%) Stannous Fluoride (SnF2) 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 0.454% SnF2 toothpaste in healthy participants with DH. The clinical efficacy of the 0.454% SnF2 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 110 participants to investigational product (approximately 55 per treatment group) and to ensure approximately 100 evaluable participants complete the entire study (approximately 50 per treatment group).

Arms:
arm 1: Participants will dose the toothbrush with a ribbon of toothpaste, across the full brush head and will 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 two 'test teeth' carefully first. Participants who wish to rinse after brushing will be instructed to rinse with 10 milliliter (ml) water using graduated rinsing cup provided. arm 2: Participants will dose the toothbrush with a ribbon of toothpaste, across the full brush head and will brush the entire dentition thoroughly for at least 1-timed minute, twice daily (morning and evening) for approximately 56 days. Participants who wish to rinse after brushing will be instructed to rinse with 10 ml water using graduated rinsing cup provided.

Interventions: intervention 1: Stannous fluoride toothpaste intervention 2: Regular fluoride toothpaste (Crest Cavity Protection)
Intervention descriptions: intervention 1: Toothpaste containing 0.454 % weight/weight (w/w) SnF2. intervention 2: Regular fluoride toothpaste containing 1100 parts per million (ppm) fluoride.
