ÖZET
 Amaç: Bu in vitro çalışmada, hidrojen peroksit ağartma materyalinin LED ışık cihazı ve diyot lazer ile kullanıldığında ağartma etkinliklerinin spektrofotometre yardımıyla karşılaştırılması ve taramalı elektron mikroskobuyla mine yüzeyindeki değişikliklerin gözlemlenmesi amaçlanmıştır. Gereçler ve Yöntemler: Çalışmada 45 adet çekilmiş insan keser dişi kullanıldı. Dişler üç gruba ayrıldı (n=15). Grup 1 (kontrol): Dişler hiçbir aktivasyon yöntemi olmadan hidrojen peroksit ile ağartıldı. Grup 2: Dişler LED ışık kaynağı kullanılarak hidrojen peroksit ile ağartıldı. Grup 3: Dişler 810 nm diyot lazer kullanılarak hidrojen peroksit ile ağartıldı. Her gruptan üçer diş mikroskobik incelemede kullanılması için ayrıldı. Dişlerin ağartma öncesi ve sonrası renk ölçümleri bir spektrofotometre ile yapıldı ve taramalı elektron mikroskobu ile görüntüler alındı. Elde edilen veriler istatistiksel analiz için kaydedildi. Bulgular: En fazla renk değişimi diyot lazerin kullanıldığı grupta gözlenmesine rağmen, LED ve diyot lazerin kullanıldığı grupların ağartma etkinlikleri arasındaki fark istatistiksel olarak anlamlı bulunmadı. Diyot lazer grubunun ağartma etkinliği kontrol grubuna göre istatistiksel olarak daha yüksek bulundu. Bu çalışmanın sonuçlarına göre, sadece diyot lazerin kullanıldığı grupta mine yüzeyinde defektler gözlendi. Sonuç: Hidrojen peroksit ile ağartma işlemlerinde diyot lazer kullanılması ağartma etkinliğinde anlamlı bir artışa neden olmuştur. Fakat diyot lazer ile yapılan ağartma işlemi sonrası mine yüzeyinde morfolojik değişiklikler gözlenmiştir.

ABSTRACT
 Objective: The aim of this in vitro study was to evaluate and compare the efficacy of hydrogen peroxide using with LED curing light and diode laser irradiation by spectrophotometer and observe it's effects on enamel structure by scanning electron microscope. Material and Methods: In this study, 45 extracted human incisors ere used. The teeth were divided into 3 groups (n=15). Group 1 (control): Bleaching with hydrogen peroxide without any activation method. Group 2: Teeth were bleached with hydrogen peroxide using LED irradiation. Group 3: Teeth were bleached with hydrogen peroxide using diode laser irradiation. Three tooth from each group was selected for microscopic examination. The color of teeth were measured before and after bleaching by spectrophotometer and scanning electron microscopy images were taken and recorded. The obtained data were recorded for statistical analyses. Results: Although the highest color change was observed in diode laser group, no statisically significant differences was found between LED and diode laser group. The bleaching efficacy of diode laser group was found statisticaly higher than the control group. Enamel surface defects were observed only in the group of diode laser according to the results of this study. Conclusion: The diode laser application in bleaching treatments with hydrogen peroxide showed significant improvement in bleaching effectiveness. However, after bleaching with diode laser, morphological changes were observed in enamel surfaces.
