“…In order to be more precise and objective, the spectrophotometer measurement was preferred over the visual evaluation [55]. Besides this, a positioning guide with orifices in the center of the middle third of teeth was fabricated [56]. This was because the middle area of teeth is generally flatter and provides a stable platform for the spectrophotometer sensor [57], and this area is the most representative tooth-color region as it reflects the light from the dentin with little influence from the enamel [56][57][58].…”

Background:The aim the study to compare the effects of pre-operative air-powder polishing and rubber-cup prophylaxis on tooth bleaching. Methods: 23 subjects suffering from discoloration, were enrolled in a randomized controlled split mouth experimental study. Before bleaching, air powder polishing (APP) and rubber-cup polishing (RCP) techniques were applied on either side of the mouth. A 40% hydrogen peroxide bleaching agent applied two 15-minute applications for in-office bleaching. The tooth bleaching effects assessed immediately after and 1 week.Results: There were no significant differences between prophylaxis groups with respect to all color parameters (∆ L, ∆a, ∆b, ∆SGU, ∆Eab, ∆ E00) at immediate period (p>0,05). At 1 week assessment period there were no significant differences between prophylaxis groups with respect to all color parameters (p>0,05) except delta E00 (p<0,05). Conclusions:Two prophylaxis techniques produced similar efficacy in bleaching treatment and the APP technique produced higher levels of color changes.

“…However, in our study treatment lasted 4 weeks, for although the manufacturers recommend 2 weeks of application, greater color stability has been described when the treatment is prolonged. Darriba et al found the daily use of 10% CP for 3 weeks to yield more stable results after 6 months than whitening treatment lasting only 2 weeks. This may be the reason why our Δ E values were higher than those published elsewhere, and were more stable over time.…”

“…A major clinical concern is the stability of the treatment outcomes over time. In this regard, a number of clinical follow‐up studies have evaluated the stability of the color afforded by different tooth whitening products, concentrations, and application protocols, although most of them only assess color stability over short periods of time, such as 6 to 8 months post‐treatment, or up to 18 months…”

Objective: To assess the whitening efficacy of a 16% carbamide peroxidase (CP) gel after 42 months of clinical follow-up. Materials and methods:A retrospective clinical study was carried out involving 95 participants. CP 16% was applied for 90 minutes a day for 4 weeks using individualized trays. Tooth color was assessed using spectrophotometry at baseline, 1 week after the end of treatment, and every 6 months until completing 42 months of follow-up. Color parameters were compared using analysis of variance for repeated measures. The analysis by teeth groups was performed using two-way ANOVA.Results: The mean baseline L* was 81.7 ± 5.2 versus 83.6 ± 8.8 after 42 months (P<.01). L* showed a decrease of 2.3 after 30 months. The values corresponding to a* before treatment were 0.4 ± 1.1 versus −1.0 ± 1.0 after 42 months (P<.01). The initial values corresponding to b* were 23.4 ± 3.3 versus 15.8 ± 1.3 after 42 months (P<.01). Values of ΔE 00 and ΔE, at the end of the treatment were 4.6 ± 1.2 and 7.8 ± 1.8, respectively. Teeth groups remained stable after 42 months of follow-up. Conclusions:The home application of 16% CP gel for 90 minutes a day for 4 weeks using individualized trays resulted in whitening that remained stable over the 42 months of follow-up.Clinical significance: Treatment with 16% CP is an effective and safe tooth whitening procedure, and the color obtained remains stable over the long term.

Background: The aim the study to compare the effects of pre-operative air-powder polishing and rubber-cup prophylaxis on tooth bleaching outcomes.Methods: 23 subjects suffering from discoloration, were enrolled in a randomized controlled split mouth experimental study. Before bleaching, air powder polishing and rubber-cup polishing techniques were applied on either side of the mouth and the tooth bleaching effects assessed immediately after and 7 days.Results: No statistically significant difference was found in for DL, Da, Db, DE and DSGU values between air-powder polishing and rubber-cup groups at immediate and 1 week.The difference between immediate and 1 week measurements is statistically significant in both air-powder polishing and rubber-cup groups, except DL for rubber-cup group, and Da, Db for air-powder polishing group.Conclusions: Within the limitations of the study, it can be concluded that there was no lasting difference in tooth bleaching effects between rubber-cup and air-polishing techniques at immediately after and 1-week post treatment.Trial registration: ClinicalTrial.gov ID: NCT04407910
