At‐Home Bleaching System: Effect on Gingival Tissue

This study evaluated the effects of an at‐home vital bleaching system on gingival responses over a 6‐week period. Objective measures were utilized to measure and monitor gingival inflammation over this period of time. Vital bleaching was performed as follows: (1) bleaching gel in a prefabricated mouthguard and (2) an ad‐mix technique – bleaching gel and toothpaste in a 1:1 ratio. In addition a control group used a placebo in a prefabricated mouthguard. The at‐home vital bleaching system produced no adverse gingival tissue responses. Furthermore, the at‐home vital bleaching system helped produce a therapeutic effect on inflamed gingival tissues over the course of the study.
