About this trial

This is an interventional treatment trial for Dentin Sensitivity focused on measuring Sensitivity

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • be at least 18 years of age
  • sign an informed consent form and be given a copy
  • be in good general health as determined by the Investigator/designee
  • agree to delay any elective dentistry, including dental prophylaxis, and to report any dentistry received during the course of the study
  • agree to not participate in any other oral care study for the duration of this study
  • agree to return for scheduled visits and follow all study procedures
  • have dentinal hypersensitivity with at least one tooth with a Schiff sensitivity score of at least 1 in response to the cold water challenge

Exclusion Criteria:

  • severe periodontal disease, as characterized by purulent exudate, generalized mobility, and/or severe recession
  • active treatment for periodontitis
  • any diseases or conditions that might interfere with the subject safely completing the study
  • inability to undergo study procedures
  • fixed facial orthodontic appliances
  • a history of kidney stones
  • self-reported pregnancy or nursing
  • known allergies to the following ingredients; aqua, glycerin, cellulose gum, dipotassium oxalate, carbomer, sodium hydroxide, sodium benzoate, and potassium sorbate

Outcomes

Primary Outcome Measures

Change From Baseline Visual Analog Scale
Visual Analog Scale (VAS) - subjects are asked to look at a VAS and designate the level of hypersensitivity they experienced as a result of the thermal and water challenges using a continuum scale of 0 = No tooth pain up to 100 = Worst tooth pain ever experienced. A negative change from Baseline score represents a decrease in sensitivity from baseline.

Secondary Outcome Measures

Change From Baseline for Air Challenge
The Schiff Sensitivity Scale was assessed for each test tooth via an evaporative air challenge. The examiner recorded the Schiff Index score corresponding to the response to the air challenge. The Schiff Index Sensitivity scale is scored as follows- 0: tooth/subject did not respond to stimulus, 1: tooth/subject responds to stimulus, but does not request discontinuation of stimulus, 2: tooth/subject responds to stimulus and requests discontinuation or moves form stimulus, 3: tooth/subject responds to stimulus, considers stimulus to be painful, and requests discontinuation of the stimulus. A negative change from Baseline score represents a decrease in sensitivity from baseline.The mean change from Baseline was calculated for this measure.
