“…A previous study showed no significant difference between bleaching efficacy when the home bleaching technique was performed alone or combined with in-office treatment (4). There is also a tendency for increased tooth sensitivity when high concentration agents are used (5,25,14).…”

This study evaluated the preferences of general dentists regarding vital and nonvital tooth bleaching therapies and investigated whether the time of clinical practice and postgraduate training influence these options. A cross-sectional study was conducted using a questionnaire with closed questions applied to dentists (n=276) of a mid-sized city of the southern Brazil (Pelotas, RS). Information was collected regarding sociodemographic variables, level of specialization and time since graduation. In addition, options regarding bleaching therapies including the first choice of material, technique and clinical practice for vital and nonvital tooth bleaching therapies were included. Data were submitted to descriptive analysis and the associations were evaluated using chi-square and Fisher exact tests (a=0.05). The response rate was 68% (n=187). At-home bleaching therapy was broadly preferred (78.1%) over in-office (21.9%) bleaching. For at-home bleaching, most dentists answered to use 10% carbamide peroxide (CP) (40.2%) and >30% hydrogen peroxide (HP) (31.7%) for nonvital therapies. The majority of dentists with post-graduation training preferred at-home bleaching techniques (p=0.003). At-home bleaching therapy was also more indicated by younger dentists. No association was found between the choice for nonvital bleaching therapies and time since graduation (p=0.532) or continuous education (p=0.083). In conclusion, at-home bleaching was preferred over in-office therapies; 10% CP and >30% HP were chosen as first option agents to treat discolored vital and nonvital teeth, respectively. The time in clinical practice and the level of specialization affected dentists' choices only for vital tooth bleaching treatment.

“…2,3 Isı ve ışık uygulanmayan sistemler genellikle %25-40 HP içeren jellerden oluşur. 4 Çalışmalarda bu jellerle başarılı sonuçlar elde edilmiş olmasına rağmen, renklenmenin şiddetine bağlı olarak istenilen beyazlatmanın 1-2 seans sürmesi bu sistemlerin dezavantajıdır. 5 Ofiste hastanın beyazlatma uygulaması sırasın-da geçirdiği süreyi azaltmak için jeller ısı, ışık ve lazer ile aktive edilmiştir.…”

ÖZETAmaç: Bu in vitro çalışmanın amacı, farklı ofis tipi beyazlatma sistemlerinin beyazlatma etkinliklerinin ve renk stabilitelerinin karşılaştırılmasıdır. Gereç ve Yöntem: Seksen adet mine-dentin örneği renklenme şiddetinin standardize edilmesi amacıyla beyazlatma öncesi Orange II boyası ile renklendirildi. Örnekler rastgele dört gruba ayrıldı (n=20): (1) %40 hidrojen peroksit jeli (Opalescence Boost PF) (OB), (2) %25 hidrojen peroksit jel + ışık aktivasyonu (Zoom 2) (Z2), (3) %38 hidrojen peroksit + ışık aktivasyonu (Signal Professional White Now) (SP), (4) beyazlatma uygulaması yapılmamış grup (kontrol). Renk değerleri dental spektrofotometre ile ölçüldü. Beyazlatma sonrası dişler 9 gün boyunca kırmızı şarapta yeniden renklendirildi. Beyazlatma sonrası renk farkı (E1), yeniden renklendirme sonrası renk farkı (E2) olarak hesaplandı. Çalışma gruplarının renk farklılıklarının karşılaştırılması tek yönlü ANOVA ve Bonferonni testleri ile gerçekleştirildi ( = 0,05). Her grubun beyazlatma ve yeniden renklendirme sonrası renk farklılıkları (E1-E2) bağımlı örneklem t-testi ile analiz edildi ( = 0,05). Bulgular: Bütün beyazlatma ajanları kontrol grubuna göre daha yüksek E1 ve E2 değerleri gösterdi (p0,05), SP ve Z2 sistemleri arasında E1 ve E2 değerleri açısından fark gözlenmezken, OB ile diğer sistemlere göre daha düşük E1 ve E2 değerleri elde edildi (p0,05). Sonuç: Işık aktivasyonlu sistemlerin beyazlatma etkinliği ışık aktivasyonsuz sistemden daha yüksek bulunmuştur.Ancak bu sistemlerde yeniden renklenmeye daha fazla yatkınlık gözlenmiştir.

Materials and Methods: Eighty enamel-dentin samples were stained with Orange II dye solution to standardize the severity of discoloration before bleaching process. Samples were randomly divided into four (n = 20): (1) 40% hydrogen peroxide gel (Opalescence Boost PF) (OB); (2) 25% hydrogen peroxide with light activation (Zoom 2) (Z2), (3) 38% hydrogen peroxide with light activation (Signal Professional White Now) (SP), and (4) no bleaching (control group). Color values were measured using a dental spectrophotometer. After bleaching, the teeth were re-stained for 9 days using red wine. The color differences after bleaching and after re-satining were reported as E1 and E2, respectively. The color difference values of study groups were compared using one-way ANOVA and Bonferonni tests ( = 0.05). The difference between E1 and E2 values of each group were analyzed using paired samples t-test ( = 0.05). Results: All bleaching systems revealed higher E1 and E2 values than control group (p0.05). There was no differences between E1 and E2 values of SP and Z2 systems, while OB produced lower E1 and E2 values than these systems (p0.05). Conclusions: Light activated bleaching systems produced higher bleaching efficacy compared to bleaching system with...
