NCT07818031
Peroxide Versus Non-Peroxide In-Office Tooth Bleaching
This randomized clinical trial aims to compare the effectiveness of peroxide and non-peroxide in-office tooth bleaching systems. The study will evaluate tooth whitening efficacy, color durability over time, and tooth sensitivity after treatment. Participants will receive one of the two bleaching treatments and will be followed for six months to assess the clinical outcomes and compare the performance of both systems.

Effectiveness of Dental Bleaching Using Different Designs of 3D-Printed and Conventional Customized Nightguards
This randomized, double-blind, split-mouth clinical trial evaluates the effectiveness of at-home dental bleaching using customized nightguards fabricated by digital (3D-printed CAD-CAM) and conventional methods, with and without reservoirs. Adult participants with good general and oral health and a baseline tooth shade of A2 or darker undergo bleaching with 10% carbamide peroxide. Outcomes include tooth color change (subjective and spectrophotometric measures), tooth sensitivity, gingival irritation, patient comfort, and patient satisfaction over time.
