ABSTRACT

Introduction: dentin hypersensitivity is characterized by sharp pain of short duration associated with exposure to thermal, tactile, osmotic or chemical stimuli. Dentin hypersensitivity is a disorder of growing prevalence which reduces the quality of life of patients.
Objective: evaluate the efficacy, acceptability and tolerance of a toothpaste with precipitated silica, potassium nitrate and sodium monofluorophosphate in patients with dentin hypersensitivity.
Methods: an observational longitudinal study was conducted (n= 22) in which the toothpaste was applied 3 times a day for 28 days. Clinical assessment was performed before and after the application, at 48 hours, at 96 hours and on days 7, 14, 21 and 28 of the study. Efficacy was evaluated in terms of dental hypersensitivity reduction as determined by tactile (Verbal Rating Scale) and air jet (Schiff scale) techniques. Tolerance to the product was assessed in every visit. Patients ranked the degree of hypersensitivity and their perception of the product by means of a subjective assessment questionnaire. The study complied with Good Clinical Practice principles.
Results: areduction was observed in dental hypersensitivity at all time points throughout the study, and it was significant (p< 0,05) as of day 5. This improvement was sustained and increased as treatment progressed. On day 29 mean hypersensitivity had reduced 85 % with respect to baseline value in all patients. 91 % of the patients stated that the toothpaste had met their expectations. No adverse reaction attributable to the product was observed.
Conclusions: applied 3 times/day, the toothpaste obtained a reduction in dental hypersensitivity, which was significant as of day 5. This improvement increased over time. The product had very good acceptability and tolerance.
