The effect of photobiomodulation therapy associated with casein phosphopeptide‐amorphous calcium phosphate fluoride paste on the treatment of posthome whitening tooth sensitivity and color change: A randomized clinical trial CARDOSO et al.

Abstract

4## DISCUSSION In this study, the null hypothesis H0 was rejected as the desensitizing treatments tested were significantly different from each other in reducing TS after at-home whitening. The PLACEBO group had the highest TS during the 21-day bleaching treatment, and the VAS scores reported by the group gradually increased over the treatment, consistent with similar results from previous studies (Ontiveros et al., ; Rezende et al., ). The continuous use of the bleaching agent during at-home whitening may have caused this gradual increase in painful symptoms. Furthermore, the timing of TS pai
