Effects of Light Activation, Agent Concentration, and Tooth Thickness on Dental Sensitivity After Bleaching

Abstract

Increases in the concentration of bleaching agents directly affect tooth sensitivity, and LED/laser activation and tooth thickness are not correlated with tooth sensitivity after dental bleaching.

A clinical, randomized, controlled study on the use of desensitizing agents during tooth bleaching

“…30 Similarly, a clinical study 31 that evaluated TS in patients treated with different bleaching techniques found that the highest TS values occurred with in-office bleaching using 35% HP (two sessions, 45 minutes each) compared with at-home bleaching with 10% CP (8 hours daily for two weeks). In contrast, Reis; Kossatz and Martins 28 showed that TS after two in-office bleaching sessions with two concentrations of HP was relatively low; however, this result can be because the tested products contained 2% calcium gluconate as a desensitizing agent.…”

Effectiveness of 6% hydrogen peroxide concentration for tooth bleaching—A double-blind, randomized clinical trial

“…[7][8][9] These concentrations show similar effectiveness, and in some cases, much lower adverse post-procedure effects. However, only one report 10 have used a concentration permitted by the European Community.…”
