Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This multicentre, non-comparative design study will monitor the impact of long term management of DH with daily use of a sensitivity toothpaste on the quality of life of a population of sensitivity sufferers. Changes in oral health related quality of life will be monitored using the Dentine Hypersensitivity Experience Questionnaire (DHEQ). The study will be conducted in participants in good general health, with pre-existing self-reported and clinically diagnosed tooth sensitivity at screening.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This will be multicenter, non-comparative design to monitor the impact of long term management of DH with daily use of a sensitivity toothpaste on the quality of life of a population of sensitivity sufferers, using the DHEQ. Changes in DH will be monitored clinically over the 24 week treatment period.

* Aged 18-55 years
* Good general and mental health with, in the opinion of the investigator or medically qualified designee: No clinically significant and relevant abnormalities of medical history or oral examination and absence of any condition that would impact on the participant's safety or wellbeing or affect the individual's ability to understand and follow study procedures and requirements
* Understands and is willing, able and likely to comply with all study procedures and restrictions
* At Visit 1 (Screening): Self-reported his of dentinal hypersensitivity (DH) lasting more than six months but not more than 10 years, minimum of 20 natural teeth, Minimum of 2 accessible non-adjacent teeth (incisors, canines, pre-molars), preferably in different quadrants, that meet all of the following criteria: Signs of facial/cervical gingival recession and/or signs of erosion or abrasion (EAR).Tooth with MGI score =0 adjacent to the test area (exposed dentine) only \[Lobene, 1986\] and a clinical mobility of ≤1 Tooth with signs of sensitivity measured by qualifying evaporative air assessment (Y/N response)
* At Visit 2 (Baseline): Minimum of two, non-adjacent accessible teeth (incisors, canines, premolars), that meet all of the following criteria: with signs of sensitivity, measured by a qualifying evaporative air assessment (Schiff Sensitivity Score ≥ 2)

Exclusion Criteria

* Women who are known to be pregnant or who are intending to become pregnant over the duration of the study
* Women who are breast-feeding
* Known or suspected intolerance or hypersensitivity to the study materials (or closely related compounds) or any of their stated ingredients
* Participation in another clinical study (including cosmetic studies) or receipt of an investigational drug within 30 days of the screening visit.

and previous participation in this study

* Recent history (within the last year) of alcohol or other substance abuse
* An employee of the sponsor or the study site or members of their immediate family
* Presence of chronic debilitating disease which, in the opinion of the investigator, could affect study outcomes and any condition which, in the opinion of the investigator, causes xerostomia
* Dental prophylaxis within 4 weeks of Screening, tongue or lip piercing or presence of dental implants, desensitizing treatment within 8 weeks of Screening (professional sensitivity, treatments and non-dentifrice sensitivity treatments), gross periodontal disease, treatment of periodontal disease (including surgery)within 12 months of Screening, scaling or root planning within 3 months of Screening and teeth bleaching within 8 weeks of Screening
* Tooth with evidence of current or recent caries, or reported treatment of decay within 12 months of Screening, tooth with exposed dentine but with deep, defective or facial restorations, teeth used as abutments for fixed or removable partial dentures, teeth with full crowns or veneers, orthodontic bands or cracked enamel. Sensitive teeth with contributing aetiologies other than erosion, abrasion or recession of exposed dentine and Sensitive tooth not expected to respond to treatment with an over-the-counter dentifrice in the opinion of the investigator
* Use of an oral care product indicated for the relief of dentine hypersensitivity within 8 weeks of screening (participants will be required to bring their current oral care products to the site in order to verify the absence of known anti-sensitivity ingredients)
* Daily doses of medication/treatments which, in the opinion of the investigator, could interfere with the perception of pain. Examples of such medications include analgesics, anticonvulsants, antihistamines that cause marked or moderate sedation, sedatives, tranquilizers, anti-depressants, mood-altering and anti-inflammatory drugs, currently taking antibiotics or has taken antibiotics within 2 weeks of Baseline and daily dose of a medication which, in the opinion of the investigator, is causing xerostomia
