“…The gingival barrier was applied to the corresponding teeth up to the second premolar region, being applied with a thickness of approximately 1 mm over the gingiva and gingival papillae, obtaining full coverage with a good protection field for the procedure. The barrier was light-cured for 20 seconds using an LED unit set at 1400 mW/cm 2 (Valo high power mode, Ultradent, South Jordan, UT, USA), and light-curing was performed immediately after application of the gingival barrier to prevent any possible irritation. Then, the bleaching gel Whiteness HP Automixx 6% (FGM, Joinville, SC, Brazil) was applied with a tip.…”

“…Recently, several clinical studies have shown excellent bleaching efficacy and fewer adverse effects when low concentrations of HP were used. 2 , 12 , 13 These aspects appear particularly crucial in younger patients, such as adolescents. The most recommended technique for them thus far has been at-home bleaching due to its low concentration.…”

At low concentrations used for in-office bleaching gels, such as 6% HP, gingival barrier continues to be performed. If we take into account that, in the at-home bleaching technique, no barrier is indicated, it seems that the use of a gingival barrier fails to make much sense when bleaching gel in low concentration is used for in-office bleaching. Objective This double-blind, split-mouth, randomized clinical trial evaluated the gingival irritation (GI) of in-office bleaching using 6% hydrogen peroxide (HP) with and without a gingival barrier in adolescents, as well as color change and the impact of oral condition on quality of life. Methodology Overall, 60 participants were randomized into which side would or would not receive the gingival barrier. In-office bleaching was performed for 50 minutes with 6% HP in three sessions. The absolute risk and intensity of GI were assessed with a visual analogue scale. Color change was assessed using a digital spectrophotometer and color guides. The impact of oral condition on quality of life was assessed using the Brazilian version of the Oral Health Impact Profile (α=0.05). Results The proportion of patients who presented GI for the “with barrier” group was 31.6% and for the “without barrier” group, 30% (p=1.0). There is an equivalence for the evaluated groups regarding GI intensity (p<0.01). Color change was detected with no statistical differences (p>0.29). There was a significant impact of oral condition on quality of life after bleaching (p<0.001). Conclusions The use or not of the gingival barrier for in-office bleaching with 6% HP was equivalent for GI, as well as for bleaching efficacy, with improvement in the impact of oral condition on quality of life.

ObjectivesEvaluate the bleaching efficacy (BE) and tooth sensitivity (TS) of in‐office bleaching using different application tips.MethodsForty‐eight participants were selected (split‐mouth), one to receive bleaching with an attached brush tip and one with a conventional tip. The procedure was performed with Whiteness Automixx Plus 35%. The BE was evaluated at the beginning, weekly, one and 12 months post‐bleaching with a Vita Easyshade spectrophotometer (ΔE*ab, ΔE00, and WID) and with Vita classical A1‐D4 and Vita Bleachedguide shade guides units (ΔSGU). Absolute risk and intensity of TS were recorded using the Visual Analogue Scale. The equivalence of BE was analyzed using the two one‐sided t‐tests for paired samples. The absolute risk of TS was evaluated using the McNemar test, and the TS intensity was measured with the paired t test (α = 0.05).ResultsThe equivalence of BE was observed for both groups in all color evaluations (p > 0.05). A lower absolute risk and intensity of TS were observed for the attached brush tip when compared with the conventional tip (p < 0.003 and p < 0.0001).ConclusionUsing an attached brush tip showed the same BE as a conventional tip. However, for the attached brush tip, there was a reduction in TS.Clinical SignificanceThe applicator‐attached brush tip is recommended for in‐office dental bleaching, because of the possible reduction in risk and intensity of TS.

This in vitro study investigates the effects of various bleaching agents on the color stability of extracted human teeth in two different staining media, Pepsi and saffron. Twenty human incisors were randomly allocated into four groups: a control group that was not treated with bleach, two groups treated with different concentrations of carbamide peroxide (22% and 16%), and a group treated with a peroxide-free bleaching agent containing phenolmidoperoxycaproic acid (PAP). Color measurements were taken at baseline, after bleaching, and following staining with either Pepsi or saffron. Statistical analysis revealed the bleaching treatments significantly affected the color, with the PAP-based bleaching agent demonstrating the lowest level of color change. Post hoc analysis confirmed significant differences between all pairs of groups, with Group 4 (PAP-based) showing the lowest mean color change. The study highlights the efficacy of peroxide-free bleaching agents and underscores its potential as a safe and effective alternative to traditional peroxide-based bleaching agents. Limitations include the in vitro nature of the study and the relatively small sample size. Future research should explore the long-term effects of different bleaching agents and staining conditions on safety and tooth color stability.
