Clinical changes in the gingiva as a result of at-home bleaching.
An investigative study was performed to evaluate changes in gingival health with the application of a 10% carbamide peroxide bleaching gel using exposure times of 2 and 7 hours (overnight). The presence or absence of gingival inflammation was recorded using the Loe and Silness Gingival Index at intervals over a 28-day period. The results showed no statistical significance between the preoperative gingival index scores and those recorded at any point during the study, regardless of exposure time.
