Effect of Bleaching Regimen With Different Activation Modes on Color Stability, Surface Roughness, Tooth Sensitivity and Patient Satisfaction
Effect of Bleaching Regimen With Different Activation Modes on Color Stability, Surface Roughness, Tooth Sensitivity and Patient Satisfaction
The purpose of this study was to conduct a randomized double-blind clinical trial to examine the efficacy of an in-office bleaching regimen with varied activation modes on color stability, surface roughness, tooth sensitivity, and patient satisfaction.
Tooth discoloration is a common esthetic concern that can negatively impact patients' self-confidence and quality of life. Contemporary restorative dentistry increasingly emphasizes minimally invasive approaches, with vital tooth bleaching emerging as a widely accepted, conservative treatment for managing extrinsic and intrinsic discoloration. The effectiveness of bleaching procedures primarily depends on the oxidative degradation of chromogenic compounds within dental hard tissues, leading to improved tooth color.
In-office bleaching techniques often incorporate various activation modes intended to enhance the efficacy of bleaching agents, accelerate treatment time, and improve clinical outcomes. These activation methods may include light-emitting diode (LED) systems, laser activation, or purely chemical activation without external energy sources. Despite their widespread use, the actual benefit of these activation modalities remains controversial, with conflicting evidence regarding their influence on bleaching effectiveness and associated adverse effects.
