Abstract

OBJECTIVE: Er:YAG laser can be used instead of air-turbine for cavity preparation in dentistry. However, the bond strength achieved after Er:YAG preparation is not as good as that achieved after bur preparation. In this study the effect of Nd:YAG laser treatment on the adhesive applied onto Er:YAG-prepared coronal dentin was investigated. Bond strength achieved in this fashion was compared with that achieved after bur preparation.MATERIALS AND METHOD: Coronal dentin was prepared either with tungsten carbide bur or with Er:YAG laser. Then, adhesive (Scotchbond Multi-Purpose, Adper Single Bond 2, Clearfil SE and Clearfil S3) was applied onto the dentin. In some of the Er:YAG-prepared teeth, the adhesive was treated with Nd:YAG laser (100 mJ, 10Hz) prior to polymerization. The bond strength was evaluated using the microtensile test.RESULTS: The bur group, as expected, revealed greater bond strength. Nd:YAG treatment increased the bond strength in all adhesive systems. Although bond strength values were still lower in the Nd:YAG-treated group, no statistically significant difference was found between the Nd:YAG-treated and bur groups (p>0.05). SEM analysis showed that coronal dentinal tubule penetration was greater when the adhesive was treated with Nd:YAG laser prior to polymerization.CONCLUSION: Treatment of the adhesives with the Nd:YAG laser was found to improve the adhesive bond strength at the coronal dentin.

Özet

AMAÇ: Er:YAG lazer, diş hekimliğinde frezlerin yerine kullanılmaya çalışılsa da adezivlerin dentine bağlanmasında frez preparasyonları kadar iyi sonuç vermemektedir. Bu çalışmada, Er:YAG lazerle prepare edilmiş dentin yüzeylerine uygulanan dört farklı adezivin (Scotchbond MultiPurpose, Adper Single Bond, Clearfil SE Bond ve Clearfil S3 Bond) Nd:YAG lazer uygulanarak ısıtılmasıyla, koronal dentine bağlanma dayanımlarında bir farklılık olup olmadığının incelenmesi ve frezle prepare edilmiş yüzeylerdeki bağlanma dayanımlarıyla kıyaslanması amaçlanmıştır.GEREÇ VE YÖNTEM: Araştırmada koronal dentin, tungsten karbid frez veya Er:YAG lazer ile hazırlandı. Er:YAG lazer grubundaki dişlerin bir kısmına uygulanan adezivler polimerizasyondan önce Nd:YAG lazer (100 mJ, 10 Hz) uygulanarak ısıtıldı. Grupların bağlanma dayanımı mikrogerilim testi ile incelendi.BULGULAR: Frez gruplarının mikrogerilim dayanımlarının Er:YAG lazer gruplarından iyi olduğu görüldü. Nd:YAG lazer uygulamasının bütün adezivlerde bağlanma dayanımını arttırdığı, nominal olarak daha düşük değerler elde edilse de frez gruplarıyla aradaki istatistiksel anlamlı farklılığın ortadan kalktığı saptandı. SEM incelemelerinde koronal dentinde adeziv üzerine polimerizasyondan önce Nd:YAG lazer uygulamasının adezivin tübül penetrasyon derinliğini arttırdığı gözlendi.SONUÇ: Bu çalışmanın sonunda adezivin ısısının arttırılmasının dentine bağlanma dayanımını geliştirdiği bulundu.
