“…Although a systematic review reported that no difference was found in color change between combined whitening and at-home whitening alone or in-office whitening alone, 6 many clinical studies have demonstrated a pronounced color improvement in combined inoffice/at-home whitening when compared to either technique used individually. [8][9][10][11][12]17 It is probable that it is difficult to select optimal combination of dual whitening because so many factors may influence the whitening efficacy, such as using products with different types of agent, concentration, frequency, period, and so on. The whitening efficacy of prefilled whitening trays containing 10% hydrogen peroxide has been found to be equivalent in whitening efficacy to 10% carbamide peroxide or 10% hydrogen peroxide delivered in a customized tray.…”

ObjectiveThis controlled randomized clinical trial determined the whitening efficacy and the intensity and absolute risk of tooth sensitivity in dual whitening when prefilled at‐home whitening trays were used between in‐office whitening intervals.Materials and MethodsAn in‐office whitening agent containing 35% hydrogen peroxide was used. A prefilled tray with a whitening agent containing 6% hydrogen peroxide was used for at‐home whitening. Sixty‐six subjects were randomly assigned to three groups. Group I: at‐home whitening was performed 10 times between the in‐office whitening treatments. Group II: at‐home whitening was performed five times between the in‐office whitening treatments. Group III: only in‐office whitening was performed. The tooth color changes were evaluated using a spectrophotometer. A visual analog scale was used to express the pain intensity.ResultsAll the groups showed increased ΔE*ab, ΔE00, and ΔWID with increased whitening sessions. Group I at the 3rd whitening session showed significantly higher ΔE*ab, ΔE00, and ΔWID than group III. Tooth sensitivity showed higher values up to 24 h after whitening.ConclusionsAlthough dual whitening with the prefilled tray and in‐office whitening had higher whitening ability than in‐office whitening alone, the intensity and absolute risk of tooth sensitivity was similar.Clinical RelevanceThe dual whitening might produce faster and stronger whitening effects than in‐office whitening alone.

“…The protocols vary in time usage, frequency, and duration of the treatment. There are reports of tray use for reduced periods of 30 min, 1 or 2 h, 19,22 or for more extended periods such as 6 h or even overnight use. 23,24 In addition, the frequency of the tray use ranged from one to three daily applications 16,25,26 in protocols that lasted 28 days 27 or even 6 months.…”

“…16,20,21 Recommendations of 30 min to 2 h daily, as well as more extended periods of time can be seen in the literature. 17,19,[22][23][24] Also, there are a huge variation in the frequency of the tray use. 16,[25][26][27][28] It is known from laboratory investigations that 1 h after application, the amount of active hydrogen peroxide in at-home hydrogen peroxide gels is reduced by approximately 30% to 50%.…”

Objective: Few studies evaluated low concentrations of hydrogen peroxide protocols. The aim of this paper was evaluated two application protocols using 4% hydrogen peroxide in at-home bleaching.Materials and Methods: Eighty-six patients with upper canines' shade A2 or darker were randomly allocated under two experimental conditions: two daily applications of 1 h each or a 2-h single application. Color change was evaluated using Vita Classical, Vita Bleachedguide, and digital spectrophotometer weekly and 1 month after the bleaching procedure through one-way ANOVA. The risk and intensity of tooth sensitivity (TS) was assessed through visual and numeric rating scale and measured by Fisher's exact test, Mann-Whitney test and one-way ANOVA respectively.Results: After 3 weeks, the mean difference for the ΔSGU Vita Classical (1.0; 95% CI À0.1 to 2.0), ΔEab (0.7; 95% CI À1.4 to 2.8), ΔE00 (0.1; 95% CI À1.4 to 1.6) and Wi (1.8; 95% CI -1.9 to 5.5) presented no difference (p > 0.08). The relative risk for TS was 0.91 (0.72 to 1.14) without significant difference neither in the risk (p = 0.6) nor in the TS intensity for both pain scales (p > 0.65). Conclusions:The application protocols evaluated (two daily applications of 1 h each or a 2-h single application) for at-home bleaching with 4% hydrogen peroxide did not showed differences in color change and tooth sensitivity.Clinical Relevance: Higher amount of active hydrogen peroxide in two daily applications for at-home bleaching neither accelerate bleaching nor increase the risk or intensity of tooth sensibility.bleaching agents, clinical trial, dentin sensitivity, hydrogen peroxide, tooth bleaching agents | INTRODUCTIONA beautiful smile is associated with health and youth, which meets patients' social, psychological, and professional expectations. 1 Clinical studies have reported that more than 50% of patients are not satisfied with the color of their teeth, 2,3 and half of these studies suggested dental bleaching as an option to improve their dental appearance. 4 Patients' increasingly intensified search for dental bleaching as well as the fact that this procedure is minimally invasive may explain why this protocol has been extensively performed in dental offices. Among the dentist-supervised techniques, dental bleaching can be performed in-office or at home. 5 In-office bleaching carries the advantage of having better professional control of the product application and faster results but with the onus of presenting higher risk and intensity of tooth sensitivity.

Diş ağartma tedavileri estetik diş hekimliğinde sıklıkla tercih edilen tedavi yöntemlerinden biridir. Bu tedavilerde hidrojen peroksit ve karbamid peroksit gibi oksitleyici ajanlar kullanılmaktadır. Bu ajanlar farklı konsantrasyonda, farklı viskozitelerde ve farklı yöntemlerle uygulanabilmektedir. Bu yöntemler arasında diş hekimi tarafından muayenehanede uygulanan ofis tipi ağartma tekniği ve hastaların evlerinde uygulayabildiği ev tipi ağartma tekniği bulunmaktadır. Ofis tipi ağartma tekniğinde ağartıcı ajan olarak genellikle farklı konsantrasyonlarda hidrojen peroksit kullanılmakta, ev tipi ağartma tekniğinde ise farklı konsantrasyonlarda karbamid peroksit kullanılabilmektedir. Ev tipi ağartma tekniğinde birçok farklı ağartma ajanı kullanılabilmektedir. Bunların arasında ağartıcı diş macunları, ağartıcı jeller ve stripler (bantlar) bulunmaktadır. Ağartma tedavisi vital ve devital dişlere uygulanabilmektedir. Ağartma tedavisinin etkinliğinin artırılması amacıyla ışık ve lazer uygulaması gibi çeşitli teknikler de kullanılabilmektedir. Ağartma tedavisinin tamamlanmasının ardından etkinliğinin devam edebilmesi amacıyla hastaya renklendirici içecekleri tüketirken pipet kullanması, renklendirici yiyecek ve içeceklerin tüketiminin ardından ağızlarını çalkalamaları ve fırçalamaları tavsiye edilmektedir. Bu tavsiyelere ek olarak ağartma tedavisinin belirli periyotlarla tekrar edilmesi de gerekebilmektedir. Ağartma ajanları diş dokularında bazı değişikliklere yol açabilmekte ve bazı riskler yaratabilmektedir. Diş dokularında hassasiyete neden olması en önemli risklerdendir. Bunun yanı sıra diş eti irritasyonlarına, pulpa hasarına ve kök rezorpsiyonlarına neden olabilmektedir. Bu derlemenin amacı diş ağartma tedavilerinin ve bu tedavilerde kullanılan güncel uygulamaların gözden geçirilmesidir.
