About

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™.

Full 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.

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.
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.

Subject is pregnant (self-reported) or breast feeding.
Subject has allergies to product ingredients, eg, rosin, mint flavoring.
Subject has systemic conditions that are etiologic or predisposing to dentin hypersensitivity (eg, chronic acid regurgitation).
Subject has excessive dietary or environmental exposure to acids at time of screening.
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.
Subject is enrolled in another clinical trial at the time of screening that would interfere with this study.
Subject is, in the opinion of the investigator, unsuitable for enrollment in the study for reasons other than those specified in the above exclusion criteria.

Individual teeth may not be included that meet any of the following criteria:
Study tooth has periodontal probing depth of ≥ 4 mm.

Study tooth has been restored in the preceding 3 months.
Study tooth is an abutment for fixed or removable prostheses or suffers traumatic malocclusion.
Study tooth is crowned or extensively restored and the restorations extending into the test area.
The tooth has dentin hypersensitivity due to cracked enamel.
