The Effect of Single and Multiple Application of In-office Dental Bleaching on Tooth Sensitivity and Bleaching Efficacy: a Single-blind Randomized Controlled Trial
King Abdullah University Hospital
60 participants
Jan 1, 2025
INTERVENTIONAL
Conditions
Summary
The aim of this study is to evaluate the effect of single versus multiple application protocols for in-office dental bleaching using two different bleaching gels (Pola Office Plus, SDI, 37.5% HP and Opalescence Boost, Ultradent, 40% HP) on the risk and intensity of tooth sensitivity, as well as the effect of the application protocol on the bleaching efficacy. Null hypothesis: There is no difference in intensity and risk of tooth sensitivity between single and multiple application of each gel and the application protocol dose not present significant effect on the bleaching efficacy.
