Amaç: Bu çalışmanın amacı, geleneksel yöntem ve Er:YAG lazerle hazırlanmış sınıf V kavitelerde farklı adeziv sistemler ve kompozitlerin neden olduğu mikrosızıntıyı incelemektir.
Gereç ve Yöntemler: Çürüme ve restorasyonu olmayan 48 daimi azı dişi çıkarılarak, artakalan dokular temizlendikten sonra distile suda muhafaza edildi. Altı dişten oluşan sekiz grup oluşturuldu; Grup-1: Frez hazırlığı (Bp)+ CLEARFIL Universal Bond Quick (UBQ)+CLEARFIL MAJESTY ES-2 Classic (ME2); Grup-2: (Bp)+Bisco Universal PrimerTM (UP)+(ME2); Grup-3: (Bp)+(UBQ)+Ceram X SphereTECTM (CX); Grup-4: (Bp)+(UP)+(CX); Grup-5: Lazer hazırlığı (Lp)+(UBQ)+(ME2); Grup-6: (Lp)+(UP)+(ME2); Grup-7: (Lp)+(UBQ)+(CX); Grup-8: (Lp)+(UP)+(CX). Tüm dişler 1500 kez termal döngüye (5–550C) tabi tutuldu. Daha sonra %0,5 bazik füçsin içerisinde 24 saat bekletildi. Boya penetrasyonu, iki gözlemci tarafından hazırlanan skor tablosuna göre stereo mikroskop altında sınıf V kavite uzunlamasına kesitlerinde, adeziv sistem-dentin ara yüzeyinde değerlendirildi. Adeziv materyal-dentin ara yüzeyleri ve hibrit tabakanın yapısı Taramalı Elektron Mikroskobu (SEM) analizi ile incelendi. İstatistiksel analizler Mann-Whitney U testi, Kruskal Wallis Tek-Yönlü Varyans Analizi ve Dunn'ın çoklu karşılaştırma testi ile değerlendirildi (p<0.05).
Bulgular: Tüm gruplarda servikal yüzeylerdeki mikrosızıntı skorlarının oklüzal yüzeylerden daha yüksek olduğu belirlendi. Ayrıca, kavite hazırlama yönteminin restorasyonların oklüzal yüzeylerindeki mikrosızıntı değerleri arasında istatistiksel olarak anlamlı bir fark yaratmadığı (p>0.05) belirlendi. Adeziv yöntemin mikrosızıntı açısından istatistiksel olarak anlamlı bir sonuç vermediği gözlemlendi (p>0.05).
Sonuç: Clearfil Majesty ES 2 kompozitin mikrosızıntı açısından daha başarılı olduğu gözlemlendi. Clearfil Majesty ES 2 kompozit sınıf V kavite restorasyonu için tercih edilebilir. Lazer ile hazırlanan kavitelerde adeziv sistemlerin performansını belirlemek için daha fazla laboratuvar ve klinik çalışmaya ihtiyaç vardır.

INVESTIGATION OF DIFFERENT ADHESIVE SYSTEMS AND COMPOSITES IN TERMS OF MICROLEAKAGE IN CONVENTIONAL METHOD AND ER:YAG LASER PREPARED CLASS V CAVITIES

Öz

Aim: The aim of this study is to examine the microleakage caused by different adhesive systems and composites in class V cavities prepared with traditional method and Er:YAG laser.
Material and Methods: 48 permanent molars without decay and restoration were removed and kept in distilled water after residual tissue were removed. Eight groups were formed with six teeth in each group; Group-1: Bur preparation (Bp)+ CLEARFIL Universal Bond Quick (UBQ)+CLEARFIL MAJESTY ES-2 Classic (ME2); Group-2: (Bp)+Bisco Universal PrimerTM (UP)+(ME2); Group-3: (Bp)+(UBQ)+Ceram X SphereTECTM (CX); Group-4: (Bp)+(UP)+(CX); Group-5: Laser preparation (Lp)+(UBQ)+(ME2); Group-6: (Lp)+(UP)+(ME2); Group-7: (Lp)+(UBQ)+(CX); Group-8: (Lp)+(UP)+(CX). All teeth were thermocycled 1500 times (5–550C). Then it was kept in 0.5% basic fuchsin for 24 hours . The dye penetration at the adhesive system-dentin interface in longitudinal sectioned class V cavities was evaluated under stereo microscopy according to the score table prepared by two observers. The adhesive material-dentin interfaces and the structure of the hybrid layer were examined by Scanning electron microscope (SEM) analysis. Statistical analyzes were tested with Mann-Whitney U test, Kruskal Wallis One-Way Analysis of Variance and Dunn's multiple comparison (p<0.05).
Results: Microleakage scores on the cervical surfaces were higher than the occlusal surfaces in all groups. In addition, it was determined that the cavity preparation method did not create a statistically significant difference between the microleakage values on the occlusal surfaces of the restorations (p>0.05). It was observed that the adhesion method did not present a statistically significant result in terms of microleakage (p>0.05).
Conclusion: Clearfil Majesty ES 2 composite was observed to be more successful in terms of microleakage. Clearfil Majesty ES 2 composite can be preferred for restoration of class V cavities. More laboratory and clinical studies are needed to determine the performance of adhesive systems in cavities prepared with laser.
