Long-term impact of NovaMin toothpaste on oral health
This study assessed the effect of continuous management of dentine hypersensitivity with twice-daily use of 5% NovaMin toothpaste over 24 weeks on oral health measures, using the Dentine Hypersensitivity Experience Questionnaire (DHEQ).
NovaMin toothpaste for dentine hypersensitivity
This double-blind, placebo-controlled, randomised study compared the clinical efficacy of a toothpaste containing 5% NovaMin with a toothpaste containing 10% strontium chloride on dentine hypersensitivity.

Dentine Hypersensitivity Experience Questionnaire (DHEQ)
This study is a pooled analysis of seven GSK clinical trials that assessed the reliability, validity and longitudinal responsiveness of the DHEQ as a measure of oral health-related quality of life. The authors also conducted exploratory analyses and validation of the short forms of the DHEQ.
GSK data on file, RH02026.
Short-term relief from dentine hypersensitivity
Three randomised controlled clinical trials compared the efficacy and safety of a toothpaste containing 0.454% stannous fluoride with a toothpaste containing 0.76% sodium monofluorophophate to relieve dentine hypersensitivity after single use and 3 days of twice-daily use.
GSK data on file: Study  205697; Study  205710; Study  207211.
Hypersensitivity relief after 8 weeks of using stannous fluoride toothpaste
This randomised clinical study compared the efficacy of a toothpaste containing 0.454% stannous fluoride with a standard fluoride toothpaste for the relief of dentine hypersensitivity after 8 weeks of twice-daily use.
Parkinson CR et al. Am J Dent 2015; 28:190–196.
This single-centre, randomised controlled study investigated dentine hypersensitivity relief after a single direct application of 0.454% stannous fluoride toothpaste and after 3 days of twice-daily use, compared with a control toothpaste containing 0.76% sodium monofluorophosphate.

Hydraulic conductance assessment of dentine permeability with Sensodyne toothpastes
This study used the hydraulic conductance in vitro model to compare changes in dentine permeability after treatment with Sensodyne Rapid Relief or an existing Sensodyne stannous fluoride formulation.

NovaMin helps protect against hypersensitivity
On making contact with saliva, NovaMin initiates a cascade of ionic exchanges, resulting in a rise in local pH level. This allows NovaMin particles to bind to collagen fibres in exposed dentine. Once bound, NovaMin particles act as calcium and phosphate reservoirs, forming a robust hydroxyapatite-like layer over exposed dentine tubules to help protect against dentine hypersensitivity pain.
Stannous fluoride formulation accelerates occlusion of exposed dentine tubules
Sensodyne stannous fluoride formulations have a balance of active stannous fluoride and bio-adhesive polymer which accelerates occlusion of dentine tubules, providing relief from dentine hypersensitivity.
