Abstract (2. Language): 
Objectives: The purpose of the present study was to evaluate microleakage in Class V cavities pretreated with different KTP (potassium–titanyl–phosphate) laser energy densities before acid etching application. Material–Method: Thirty–two human premolars were selected for cavity pretreatment. After Class V cavity restorations in buccal and lingual surfaces, teeth were randomly divided into four groups: Group 1: 1 W, 7.1 J/ cm2 KTP laser, 37% phosphoric acid and Single Bond; Group 2: 1.5 W, 10.7 J/cm2 KTP laser, 37% phosphoric acid and Single Bond; Group 3: 2 W, 14.2 J/cm2 KTP laser, 37% phosphoric acid and Single Bond; Group 4: 37% phosphoric acid and Single Bond. The cavities were restored with composite resin. The teeth were then thermocycled for 500 cycles, isolated and immersed in 0.5% basic fuchsin for 24 h. After this period, the teeth were rinsed, dried, and sectioned, and microleakage was assessed by dye penetration at the occlusal and gingival surface of the teeth with stereomicroscope (X6). Data were analyzed with Kruskal–Wallis and Mann–Whitney U tests for independent samples, and Wilcoxon test for dependent samples. Results: When microleakage at the enamel margins of all groups were compared, no statistical differences were found (p>0.05). There was a statistically significant difference between Groups 3 and 4 (p<0.05) when the scores of microleakage at the cementum margins of the four groups were compared; however, no other groups showed statistically significant differences between them (p>0.05). Discussions: None of the procedures tested in this study completely eliminated microleakage. KTP laser irradiation prior to acid etching to dentin following cavity preparation reduced mean microleakage values compared with acid etching alone at the enamel and the cementum margins.

Amaç: Bu çalışmanın amacı, Sınıf V kavitelerin asitle pürüzlendirilmesi öncesinde uygulanan farklı enerji yoğunluklarındaki KTP (potasyum–titanil–fosfat) lazer ile mikrosızıntıyı değerlendirmektir. Materyal–Metod: 32 tane premolar diş kavite preparasyonu için seçildi. Bukkal ve lingual yüzeylere Sınıf V kaviteler açıldıktan sonra, dişler rastgele 4 gruba ayrıldı. Grup 1: 1 W, 7,1 J/cm2 KTP lazer, %37 fosforik asit ve Single Bond; Grup 2: 1,5 W, 10,7J/cm2 KTP lazer, %37 fosforik asit ve Single Bond; Grup 3: 2 W, 14,2 J/cm2 KTP lazer, %37 fosforik asit ve Single Bond; Grup 4: %37 fosforik asit ve Single Bond. Bütün kaviteler kompozit rezin ile restore edildi. Dişlere daha sonra 500 kez termal siklus uygulandı ve 24 saat %0,5’lik bazik fuksinde bekletildi. Bu işlemden sonra, dişler yıkandı, kurulandı ve kesildi ve dişlerin oklüzal ve gingival yüzeylerinde boya penetrasyonu ile oluşan mikrosızıntı stereomikroskop altında değerlendirildi (X6). Elde edilen veriler bağımsız örnekler için Kruskal–Wallis ve Mann–Whitney U testi, bağımlı örnekler için ise Wilcoxon testi yapıldı. Bulgular: Bütün gruplarda mine marjininde oluşan mikrosızıntı değerleri karşılaştırıldığında istatistiksel olarak anlamlı fark bulunmadı (p>0,05). Bütün gruplarda sement marjinindeki mikrosızıntı değerleri karşılaştırıldığında ise, Grup 3 ve Grup 4 arasındaki fark istatistiksel olarak anlamlı bulunurken (p<0,05), diğer gruplar ile arasındaki fark anlamlı bulunmadı (p>0,05). Tartışma: Bu çalışmada kullanılan yöntemlerin hiçbirisi mikrosızıntıyı önleyemedi. Kavite preperasyonu sonrası asit etching uygulamasından önce KTP lazer uygulaması ile mine ve sement marjinlerinde elde edilen mikrosızıntı değerlerinin, sadece asitle pürüzlendirme sonrası elde edilen değerlere göre azaldığı görüldü.
