The purpose of this study was to assess the effect of topical application of a sustained-release device in form of a varnish containing strontium chloride on dentinal hypersensitivity. Sixty teeth were selected in ten patients. The teeth were divided in a) varnish application containing strontium chloride, b) varnish application with no active ingredient, c) untreated teeth. Varnish application was carried out by the patients once daily for 30 days. Results show a marked decrease in hypersensitivity to both mechanical (54%) and thermal stimuli (38%) as compared to the placebo and untreated group.
