“…The results from this study could indicate that the recommended application time of the trays should be greater than 30 min. This would be in agreement with the the results obtained by Cardoso et al who stated that the contact time of the gel with the surface of the tooth is in important in the efficacy of bleaching, having compared distinct tray application times 13) .…”

“…This would explain the higher concentrations of active ingredient in maxillary trays as they were less contaminated than those of the mandibular. Contamination may also reduce bleaching in the lower arch, although clinical effectiveness studies of whitening gels have only assessed color in the upper arch [10][11][12][13] . Matis et al argued that the difference in the degree of whitening in trays with and without reservoirs is not noticeable visually 30) .…”

“…Recommended daily application times vary according to the concentration of the active ingredient (from 30 min to all night). The recommended duration of treatment ranges from two to four weeks 6,[10][11][12][13] . The most common side effects of whitening are tooth sensitivity, which can occur spontaneously or with temperature changes, and gingival irritation [14][15][16] .…”

This study investigated hydrogen peroxide (H 2 O 2 ) concentration of two home bleaching gels, in their dispensing syringes and their degradation in vivo in intraoral bleaching trays. Two bleaching gels were studied, 7.5% hydrogen peroxide (HP) and 20% carbamide peroxide (CP). The concentration of H 2 O 2 was determined in dispensing syringes. Twenty individuals were involved in this study. The gels were placed in trays of both arches and their degradation determined at 5, 10, 15, 20, 30, 40, 60 and 75 min. The concentrations of H 2 O 2 in syringes were (HP) 8.12% and (CP) 7.95%. For the HP gel in custom-trays the concentration of H 2 O 2 was 73% at 5 min and 42% after 75 min. In the 20% CP gel it was 75% at 5 min and 39% after 75 min. Activity decreased linearly up to 75 min, where the mean concentration of H 2 O 2 exceeded 35% for the CP and HP gels.

“…The shade matching was performed in the middle one third of the facial surface of the anterior central incisor. 18,19 Two experienced and calibrated examiners, blinded to the group allocation, scheduled these participants for bleaching and evaluated their teeth against the shade guide at baseline, 1-week after the first appointment, and 1-week after the second appointment. The examiners were required to have an agreement of at least 85% (Kappa statistic) before examination.…”

Abstract:The study aimed to evaluate the effectiveness of in-office bleaching and associated tooth sensitivity on application of nano-calcium phosphate paste as desensitizing agent. Bleaching was performed with 35% hydrogen peroxide gel in 40 patients who were randomly divided into placebo and nano-calcium phosphate paste groups. Bleaching efficacy (BE) was evaluated using a value-oriented Vita shade guide. Tooth sensitivity was recorded using a numeric rating scale (0-4) during bleaching and up to 48 h after each session. The primary outcome of absolute risk of tooth sensitivity was compared using the Fisher's exact test (α = 0.05). The intensity of tooth sensitivity and the efficacy of in-office bleaching were also statistically evaluated. No significant differences in absolute risk and intensity of tooth sensitivity were detected between the groups (p = 1.0 and p = 0.53, respectively). BE was also found to be similar between the groups (p = 0.67). Although the use of a nano-calcium phosphate paste associated with fluoride and potassium nitrate did not influence the whitening outcome, but it also did not reduce bleaching-induced tooth sensitivity.

“…15 Taking into account that a young patient's pulp is wider than that of an adult patient, and that the diffusion of hydrogen peroxide at high concentrations into dental tissues is extensive, [16][17][18] a safer treatment was selected for the current patient: 10% carbamide peroxide, reducing the possibility of sensitivity. [19][20][21] This treatment was performed in an individualized way for this patient: using direct applications on the more pigmented areas followed by application with personal trays for 14 days, and only with the affected teeth.…”

SUMMARYIn some patients with labial white stains involving the enamel and dentin, bleaching associated with a restorative procedure using composites may be an appropriate treatment alternative. Although bleaching makes the teeth and the stain whiter, the staining is less evident and easier to restore. Restorative procedures using adequate composites may then recover the natural optical properties while also providing appropriate mechanical properties, thereby ensuring the longevity of the treatment. In this article, the clinical case of a 9-year-old patient who reported dissatisfaction with her smile because of the presence of hypoplastic enamel staining at the central superior and inferior incisors is reported. The treatment consisted of a bleaching protocol followed by composite resin restorations using the stratification technique. The final esthetic result demonstrated the possibility of obtaining a natural smile with an adequate color and natural-looking restorations, thereby ensuring the esthetics and the patient's functional satisfaction.
