Evaluation of the Combined Effect of Bioactive Toothpastes, Desensitizing Agents and Er-YAG Laser on Dentin Hypersensitivity: an In-Vivo Study

In the laser treatment groups, the Fotona LightWalker® Erbium laser (2,940 nm) will be used, with each session lasting five minutes. During treatment, the energy density will be set to 20 J/cm², and the laser tip will be held perpendicular to the target area, applied in continuous and contact modes.

"Mix the product for 15 s. Apply in a thin layer on treatment area(s) with aid of a microbrush, with no rinsing or removal"

"Simulation of a single layer application (15s) , with the aid of a microbrush, on the surface of the tooth and with no rinsing or removal."
