Evaluation of the Combined Effect of Bioactive Toothpastes, Desensitizing Agents and Er-YAG Laser on Dentin Hypersensitivity: an In-Vivo Study
Sponsor: Ege University
Summary
Here's the revised version with the corrected treatment and follow-up session schedule: \--- The aim of this clinical trial is to evaluate the effectiveness of bioactive toothpastes, desensitizing agents, and Er-YAG laser treatments in reducing dentin hypersensitivity. This study also aims to assess the safety and comparative efficiency of these treatment methods. The main research questions are: * Do bioactive toothpastes, desensitizing agents, and laser treatments individually or in combination reduce dentin hypersensitivity? * Are there any adverse effects associated with these treatments? Participants will: * Be randomly assigned to one of four treatment groups, each using a specific toothpaste (Pro-Argin, Nano-Hydroxyapatite, NovaMin, or CPP-ACP), alongside desensitizing agents, laser treatments, or a placebo. * Receive two treatment sessions: the first at baseline and the second one week later. * Attend follow-up evaluations at the 2nd week, 1st month, and 3rd month to assess dentin hypersensitivity using the Visual Analog Scale (VAS) and dental unit air-water sprays. Researchers will compare the outcomes across groups using statistical analyses (Kolmogorov-Smirnov, Kruskal-Wallis, and Pearson/Spearman tests) to determine the most effective approach for managing dentin hypersensitivity.

Interventions
laser treatment
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.
application of desensitizing agent
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
Placebo
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.
