The Influence of Isolation Techniques in Gingival Irritation During an In-office Bleaching

The objective of this study was to evaluate if two different isolation techniques used during in-office bleaching influence the risk of gingival irritation. The secondary objectives were to investigate whether the isolation technique affects bleaching efficacy, the occurrence of tooth sensitivity, and the intensity of tooth sensitivity (TS).
