RESUMO

PURPOSE: To evaluate the clinical efficacy of a single professional application of a Pro-Relief desensitizing fluoride-free paste containing 8% arginine and calcium as compared to a fluoride-free prophylaxis paste on dentin hypersensitivity reduction in adults with a clinical diagnosis of dentin hypersensitivity. METHODS: This single-center, parallel group, double-blind and randomized clinical study conducted in Santo Domingo, Dominican Republic included 50 (25 per group) adult male and female subjects. Each study subject had two teeth hypersensitive to air blast stimuli when applied directly at its cervical surface (gingivo-facial 1/3). An air blast hypersensitivity score equal or greater to 2 (Schiff Cold Air Sensitivity Scale) was randomly assigned to one of two treatment groups (1) Pro-Relief in-office desensitizing fluoride-free paste containing 8% arginine and calcium carbonate (Test Paste group), and (2) a fluoride-free prophylaxis paste (Control Paste group). Prior to their baseline examination, subjects were instructed to return to the clinical facility having refrained from eating and drinking for 2 hours. An assessment of air blast hypersensitivity and examinations of oral soft and hard tissue were performed at the baseline. Subjects were provided a professional in-office prophylaxis with their assigned prophylaxis paste. A post hypersensitivity examination was performed immediately after the oral prophylaxis. RESULTS: All subjects completed the study. At the post-hypersensitivity examination, subjects assigned to the Test Paste group and Control Paste group both exhibited statistically significant (P = 0000) reductions (compared to baseline), to air blast hypersensitivity of 44.7% and 25.6%, respectively. At the post-hypersensitivity examination, subjects in the Test Paste group exhibited a statistically significant (P = 0.005) reduction of 24.4% in mean air blast hypersensitivity scores as compared to the Control Paste group.
