OBJECTIVE: The objective of this 16-week, double-blind, randomized, switch-over design study was to compare the efficacy in reducing dentin hypersensitivity of a dentifrice containing 8.0% arginine, calcium carbonate, and 1450 ppm fluoride as sodium monofluorophosphate (Colgate Sensitive Pro-Relief [also marketed as elmex Sensitive Professional]) to a desensitizing dentifrice containing 8% strontium acetate and 1040 ppm fluoride as sodium fluoride (Sensodyne Rapid Relief) under relevant consumer usage conditions.
OBJECTIVES: A product comparison study to compare the short term clinical efficacy of a strontium acetate/silica toothpaste with an arginine/calcium carbonate paste for pain reduction in dentine hypersensitivity. METHODS: The study was examiner blind of two arm parallel design. Eighty healthy adult subjects from general dental practice with ≥2 sensitive teeth but otherwise good oral health, were enrolled and randomised to 1 of 2 toothpaste treatments, schedule provided by the sponsor. Almost equal numbers received each treatment.
BACKGROUND: The aim of the present study is to evaluate the relative abilities of three desensitizing dentifrices to provide rapid relief of dentin hypersensitivity (DH). METHODS: Using a double-mask, randomized design, three dentifrices: 1) containing 8% arginine and 1,450 ppm sodium monofluorophosphate; 2) containing 8% strontium acetate and 1,040 ppm sodium fluoride; and 3) containing 30% microaggregation of zinc-carbonate hydroxyapatite nanocrystals were compared after 3-day treatment.
