Masking
QUADRUPLE (Subject, Caregiver, Investigator, Outcomes Assessor)

Masking description

The tubes of test dentifrices will present the same shape/color to avoid that both investigators and subjects can identify the dentifrices.

Intervention model description

This study will be monocentric, randomized, double-blind, two-treatment, parallel clinical study

Inclusion criteria

* Male and female subjects, ages 18-70, inclusive. * Availability for the eight-week duration of the study. * Two sensitive teeth, which must be anterior to the molars, and demonstrate cervical erosion/abrasion or gingival recession. * Qualifying response to tactile stimuli (Yeaple probe) as defined by a score between 10-50 gms. of force. * Qualifying response to the air blast stimuli as defined by a score of 2 or 3 on the Schiff Cold Air Sensitivity Scale. * Subjects need to satisfy the qualifying response to stimuli for both the parameters assessed (tactile or air) on two teeth to be entered into the study. * Good general health with no known allergies to products being tested. * Use of a non-desensitizing dentifrice for three months prior to entry into the study. * Signed Informed Consent Form.

Exclusion criteria

* Gross oral pathology, chronic disease, or history of allergy to test products. 2. Advanced periodontal disease or treatment for periodontal disease (including surgery) within the past twelve months. * Sensitive teeth with a mobility greater than one. * Teeth with extensive/defective restorations (including prosthetic crowns), suspected pulpitis, caries, cracked enamel, or used as abutments for removable partial dentures. * Current use of anticonvulsants, antihistamines, antidepressants, sedatives, tranquilizers, anti-inflammatory drugs, or daily use of analgesics. * Participation in a desensitizing dentifrice study or regular use of a desensitizing dentifrice within the past three months. * Current participation in any other clinical study. * Pregnant or lactating subjects. * Allergies to oral care products, personal care consumer products, or their ingredients. * Medical condition which prohibits not eating/drinking for 4 hours.

Primary

MeasureTime frameDescription
Tactile Sensitivity using the Yeaple Electronic Force Sensing Probebaseline, 3 day, 4 weeks, 8 weeksTactile sensitivity will be assessed by use of Sensing Probe Yeaple Electronic Force Sensing Probe, Model 200A. Sensitivity will be defined by a score in the range of 10-50 gms. of force.
Air Sensitivity using the Schiff Cold Air Sensitivity Scalebaseline, 3 day, 4 weeks, 8 weeksThe air will be directed at the exposed buccal surface of the sensitive tooth air delivered by a standard dental unit syringe at a measured temperature of 19-21°C (70°F\[± 3°F\].
