A Clinical Study of Two Dentinal Hypersensitivity Treatments Used With Normal Oral Hygiene

September 8, 2020 updated by: Procter and Gamble

A Randomized Clinical Study of the Safety and Effectiveness of Two Dentinal Hypersensitivity Treatments Used With Normal Oral Hygiene

This study will compare the safety and effectiveness of normal oral hygiene with two different marketed dentifrices, on longer term dentinal hypersensitivity response following use of potassium oxalate desensitizers.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline Air Challenge
Time Frame: 60 days
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/subjects responds to stimulus and requests discontinuation or moves from stimulus, 3: tooth/subject responds to stimulus considers stimulus to be painful, and requests discontinuation of the stimulus. The higher the Schiff score, the more sensitive the tooth. The mean change from Baseline was calculated for this measure.
60 days

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline Visual Analog Scale
Time Frame: 60 days
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.
60 days
