- Conditions
- Dentinal Hypersensitivity
- Interventions
- Device: V063B-DP3003
- Registration Number
- NCT02466945
- Lead Sponsor
- Pierre Fabre Dermo Cosmetique
- Brief Summary
The aim of this clinical trial is to evaluate the tolerance and efficacy of a dental gel in patients with dentinal hypersensitivity.
- Detailed Description
The aim of this clinical trial is to evaluate the tolerance and efficacy of dental gel V063B-DP3003 in patients with dentinal hypersensitivity, under normal conditions of use, under dentist control.
The primary objective of this study is to evaluate the global oral and dental tolerance of the studied product after 28 days of use.
Some efficacy objectives have been added to observe the efficacy of the dental gel. The dentinal hypersensitivity will be evaluated by the investigator with a thermal stimulus on two sensitive teeth selected by the investigator.

Group Intervention Description V063B-DP3003 V063B-DP3003 all patients will received the study product (V063B-DP3003)
- Primary Outcome Measures
Name Time Method Global tolerance according to a 5-point grading scale taking into account physical signs observed and graded by the dentist and functionnal signs observed and graded by the patient after 28 days The global tolerance of the product is assessed by the dentist after 28 days of use, rated on a 5-point grading scale(good tolerance, very good tolerance, good tolerance, moderate tolerance) . The results of the global tolerance will take into account the physical signs observed by the dentist and the functional signs observed by the patients during the study
- Secondary Outcome Measures
Name Time Method Tolerance with the record of functionnal signs reported by the dentist and physical signs reported by the patient. during 28 days Evaluate the oral and dental tolerance of the studied product thanks to functionnal signs reported and graded by the patient following a scale from 0=none to 4=severe and by the clinical examination of physical signs performed and graded by the investigator with a scale from 0=none to 4=severe
Acceptability of the product assessed with a questionnaire during 28 days Evaluate acceptability with a questionnaire filled out by the subject on day 28.
Cold air stimulus score on the schiff cold air index as a mesure of immediate efficacy 5 and 60 minutes after application at day 1 Immediate efficacy of the product at 5 and 60 minutes after application at day 1, according to Cold air Stimulus by delivered from a standard dental unit syringe and assessment of the score on the Schiff Cold air index with several measures.
Cold air stimulus score on the schiff cold air index as a mesure of efficacy between baseline and day 28 Evaluate the efficacy on dentinal hypersensitivity of the product between baseline and day 28, according to Cold air Stimulus by delivered from a standard dental unit syringe and assessment of the score on the Schiff Cold air index.
