“…58,60,63,64 However, in the later clinical trials, measurements were performed at the end of the treatment, which does not take into consideration the rebound effect observed within the forthcoming days and weeks. 65 It has been shown that bleaching induces enamel and dentin demineralization, as measured by changes in microhardness values, which is followed by a remineralization process [21][22][23][24][25][26] ; this likely explains changes in tooth appearance such as the short-term higher enamel brightness and opacity. It therefore appears mandatory to assess the clinical efficacy of bleaching not only immediately after completion of the treatment but also after a few months at least, so that an objective comparison of treatment modalities can be performed.…”

“…A common clinical side effect of in-office whitening is thermal sensitivity. 13,[17][18] This may occur during the whitening procedure and usually stops when treatment is suspended. 15,19 Gingival irritation caused by whitening agents has also been reported.…”

“…15,19 Gingival irritation caused by whitening agents has also been reported. [13][14][17][18][19] In order to avoid tissue irritation during at-home whitening, the whitening trays are scalloped to minimize contact of the gel with the gingiva. Moreover, the patients are instructed to wipe any excess gel off of the gingiva.…”

Clinical RelevanceFive days of at-home whitening with 10% carbamide peroxide (eight hours/day) produces a similar tooth whitening result as one in-office treatment with 25% hydrogen peroxide (one hour). SUMMARYObjective: This study evaluated the time necessary for at-home whitening (HW) to match the results of an in-office (OW) treatment, side effects and patients' preferences/perceptions. Methods: The tooth color change of 20 subjects was measured using a shade guide (BSG) and spectrophotometer (ES). Color difference was calculated:. The whitening treatments were randomly applied to the right or left maxillary anterior teeth, in-office, with 25% hydrogen peroxide or at-home, overnight, with 10% carbamide peroxide. The tooth color was evaluated at baseline, one day after OW, six days (five days after HW) and at 20 days (14 days after HW and 19 days OW). Subjects rated their tooth and soft tissue sensitivity (1-10 scale). The results were analyzed by two-way RM ANOVA/Tukey's and Mann-Whitney (p<0.05). Results: At six days, the teeth that were treated with HW and OW presented ∆ ∆E* = 5.2 and 6.6, respectively, ∆ ∆BSG=3, and at 20 days, they presented ∆ ∆E* = 6.2 and 6.6, respectively, ∆ ∆BSG = 3. Less than 40% of the subjects experienced tooth sensitivity after OW and HW. No subjects experienced tooth and gingival sensitivity at 20 days.

Aim: This study evaluated the infl uence of 20% sodium ascorbate (SA) and 10% ascorbic acid (AA) hydrogels on the microleakage of class V composite restorations after an offi ce bleaching protocol (B). Methods: Sixty bovine incisors were sectioned at one point extending 8 mm from the amelodentinal junction toward the incisal edge, and at a second point extending 2 mm from the amelodentinal junction toward the root apex. Root canals were sealed with a composite and the teeth were divided into 5 groups. In Group C (control group), the teeth were prepared (P; 4 × 3 mm depth × diameter; diamond bur 3131, KG Sorensen), etched, rinsed (ER), submitted to an adhesive system protocol (Ambar, FGM), and restored (R) with a microhybrid composite (Opallis, FGM); In Group IR, the teeth were bleached (B; 2 sessions, 1 week interval, 35% hydrogen peroxide, Whitness HP Blue, FGM) + P + ER + R; In Group SA, teeth were B + P + SA (20%/15 minutes) + ER + R; In Group AA, teeth were B + P + AA (10%/15 minutes) + ER + R; and in Group MR, the teeth were B + stored in water (37°C/14 days) + P + ER + R. Specimens were submitted to an aging process by thermocycling (5 × 10 4 cycles of 5°C and 55°C with a dwelling time of 30 s), varnish-sealed, immersed in basic fuchsin (3 h), washed and sectioned with a diamond disc. Microleakage was measured with the aid of ImageTool  software. ANOVA and Tukey's post hoc test (p < 0.05) were applied. Results: Microleakage (mm) and standard deviations per group were as follows: C, 0.29 (0.06) A ; IR, 1.86 (0.15) C ; SA, 1.08 (0.09) B ; AA, 1.07 (0.10) B ; MR, 1.02 (0.12) B . Conclusions: Bleached teeth submitted to superfi cial treatment with 20% SA and 10% AA applied for 15 minutes prior to restoration presented reduced microleakage, as compared to immediately restored bleached teeth. Use of these antioxidants led to a microleakage comparable to that observed after a waiting period of 14 days prior to restoration.
