Amaç: 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 (DE1), yeniden renklendirme sonrası renk farkı (DE2) olarak hesaplandı. Çalışma gruplarının renk
farklılıklarının karşılaştırılması tek yönlü ANOVA ve Bonferonni testleri ile
gerçekleştirildi (a = 0,05). Her
grubun beyazlatma ve yeniden renklendirme sonrası renk farklılıkları (DE1-DE2) bağımlı örneklem t-testi ile analiz edildi (a = 0,05).

Bulgular: Bütün
beyazlatma ajanları kontrol grubuna göre daha yüksek  DE1 ve DE2 değerleri gösterdi (p<0,05), SP ve Z2 sistemleri arasında DE1 ve DE2 değerleri açısından fark gözlenmezken, OB ile diğer
sistemlere göre daha düşük DE1 ve DE2 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.

COMPARISON OF BLEACHING EFFICACY AND COLOR STABILITY OF
DIFFERENT IN-OFFICE BLEACHING SYSTEMS

ABSTRACT

Aim: The purpose of this in vitro study was to evaluate the
bleaching efficacy and colour stability of different in-office bleaching
systems.

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 DE1 and DE2, respectively. The color difference values of study
groups were compared using one-way ANOVA and Bonferonni tests (a = 0.05). The difference between DE1 and DE2 values of each group were analyzed using paired
samples t-test (a = 0.05).

Results: All bleaching systems revealed higher DE1 and DE2 values than control group (p<0.05).  There was no differences between DE1 and  DE2 values of SP and Z2 systems, while OB produced lower
DE1 and DE2 values than these systems (p<0.05).

Conclusions: Light
activated bleaching systems produced higher bleaching efficacy  compared to bleaching system without light
activation. However, they showed higher staining susceptibility after bleaching
than bleaching system without light activation.

Key words: Bleaching, hydrogen peroxide, light activator
