ABSTRACT
BACKGROUND AND OBJECTIVES:
Cervical dentin hypersensitivity is a routine clinical condition caused by dentin exposure to the oral environment and sensitivity caused by the ingestion of cold, sweet or sour foods, which induces localized, acute and brief pain. This study aimed at clinically evaluating the efficacy of two treatments to improve cervical dentin hypersensitivity, as well as the duration of their effects.
METHODS:
The study was developed as a clinical, doubleblind and comparative study where 14 patients with cervical dentin hypersensitivity treated in the Clinic School of Dentistry of the University Center Cesmac were selected. Participants were divided in two groups of seven individuals. The first group was submitted to treatment with 5% potassium nitrate desensitizing (Nano P®-FGM) and the second group received fluoride varnish applications (Fluorniz®-SS White). Both treatments have followed manufacturers’ instructions.
RESULTS:
Clinical evaluations were performed 7, 14, 21 days and 1 month after treatment. After statistical analysis of results, it was possible to conclude that products have improved initial cervical dentin hypersensitivity in studied dental elements after their applications and that the desensitizing effect of potassium nitrate was longer lasting as compared to fluoride varnish.
CONCLUSION:
Potassium nitrate desensitizing effect was longer lasting as compared to fluoride varnish.
