Dentin Hypersensitivity

Brief summary

The goal of this clinical trial is to evaluate the effect of 3M™ Clinpro™ Fluoride Aqueous Solution (experimental) on Dentin Hypersensitivity (DHS) in comparison to 3M™ Vanish™ (commercialized, control\] in patients who have DHS. Participants will be asked to complete the following activities: Undergo a pre-treatment washout period for 3- to 6-weeks (± 4 days) post-enrollment. During this time, the Subject is to only use the provided oral hygiene products. Hypersensitivity will be assessed prior to (baseline) and immediately after sample application. Subject will be asked to come to the facility for hypersensitivity assessments at 24 hours, 7 days, and 30 days after the treatment visit. Researchers will compare 3M™ Clinpro™ Fluoride Aqueous Solution to 3M™ Vanish™ to evaluate if the effect of Clinpro™ on DHS treatment is non-inferior to Vanish™.

Detailed description

After Informed Consent has been obtained, the subjects will be given study supplied oral hygiene products (e.g., toothbrush and toothpaste) to be used immediately after the consent visit and throughout the entire duration of the study. Subjects will have a minimum wash-out period of 3 weeks followed by 1 treatment visit. At the treatment visit, a pain assessment will be performed (ie, a baseline pain score) in response to both an air-blast stimulus and tactile stimulus. After each stimulus, the Subject should score their pain using a Visual Analog Scale (VAS). After recording baseline pain scores, Clinpro™ (Treatment arm) or Vanish™ (Control arm) will be applied according to the manufacturer's IFU. Pain in response to air blast and probe test will be assessed using VAS immediately after application of fluoride treatment (within 15 minutes). Pain response will be assessed again at 24 h, 7 d, 21 d and 30 d post-application of the treatment.

Inclusion criteria

1. Subject has at least one affected hypersensitive tooth upon air blast stimuli in the cervical area, and baseline pain score of 40 mm and above as assessed by the 100 mm VAS. 2. Subject is at least 18 years old and have a minimum of 20 natural teeth. 3. Subject is willing to withhold desensitizing treatment, including prescription, in-office or over the counter (OTC) desensitizing products, throughout the study period AND withhold during the washout period. 4. Subject agrees to only use the provided toothpaste, toothbrush, and follows all oral hygiene instructions throughout the study period AND follows all oral hygiene instructions during the washout period. 5. Subject is able to understand and willing to sign the Informed Consent, and is willing to return to the study facility for scheduled study visits and recalls.

Exclusion criteria

1. Subject has medical (including psychiatric) and pharmacotherapeutic histories that may compromise the protocol - including the chronic use of anti-inflammatory, analgesic (pain), and mind-altering drugs; or analgesic (pain) medications within 48 hours prior to application of treatment. 2. Subject is pregnant (self-reported) or breast feeding. 3. Subject has allergies to product ingredients, eg, rosin, mint flavoring. 4. Subject has systemic conditions that are etiologic or predisposing to dentin hypersensitivity (eg, chronic acid regurgitation). 5. Subject has excessive dietary or environmental exposure to acids at time of screening. 6. Subject had periodontal treatment, bleaching treatments, or orthodontic treatments within previous 3 months or plans to have any other dental treatments during the study period. 7. Subject is enrolled in another clinical trial at the time of screening that would interfere with this study. 8. Subject is, in the opinion of the investigator, unsuitable for enrollment in the study for reasons other than those specified in the above

Change in Pain From Baseline Immediately After Application of Test Product.Base line and immediately after application (within 15 minutes post-treatment).Change in sensitivity as assessed using a Visual Analog Scale (VAS, 0 - 100 mm) immediately after exposure to air stimulus relative to baseline. The VAS consists of a 100mm line, with two extremes being 0 mm (no pain) and 100 mm (worst pain). Higher scores mean a worse outcome.
