In-office Treatments for Dentin Hypersensitivity: A Randomized Split-mouth Clinical Trial.

Purpose: To assess the effectiveness of four in-office therapies used for the treatment of dentin hypersensitiviy (DH) after one single application.

Materials And Methods: A randomised, controlled, split-mouth clinical trial was designed to evaluate the following treatments: 5% sodium fluoride varnish (positive control); 3% potassium oxalate; two-step self-etching adhesive; high power diode laser. Nineteen patients were selected and one tooth per quadrant was included in the study.

Micromorphological evaluation of dentin treated with different desensitizing agents.

Introduction: The purpose of a desensitizing agent is a permanent coating or filling of dentin surface. Morphological analysis in vitro of this treated surface is essential to understand the interaction between desensitizing agent and hypersensitive dentin. The aim was to evaluate the morphology of four dentin surface treated with desensitizing agents.
