Effectiveness of nano-calcium phosphate paste on sensitivity during and after bleaching: a randomized clinical trial
<p>The study aimed to evaluate the effectiveness of in-office bleaching and associated tooth sensitivity on application of nano-calcium phosphate paste as desensitizing agent. Bleaching was performed with 35% hydrogen peroxide gel in 40 patients who were randomly divided into placebo and nano-...
