AIM: The aim of this in vitro study was to investigate the effectiveness of Sodium Fluoride, Propolis and Er,Cr:YSGG laser alone and in combination with laser applications on dentin tubules by SEM and to examine the effects of these applications on the shear bond strength (SBS) of a universal adhesive to dentin.
METHODS: Dentin samples obtained by removing the buccal enamel of 72 caries-free permanent, mandibular third molars were randomly divided into six groups (n:12): Control, Sodium Fluoride (Enamelast, Ultradent), Propolis (Fanus Propolis), Er,Cr:YSGG Laser (Biolase, Waterlase), Enamelast-Er,Cr:YSGG Laser, Propolis-Er,Cr:YSGG Laser. While the agents were applied to the dentin surfaces in the agents alone groups, laser was applied after the agent applications in the combination groups. No application was performed to the control group. After storing the samples in artificial saliva for 14 days, Clearfil Tri-S Bond Universal (Kuraray) and composite resin (Estelite Sigma Quick, Tokuyama) were applied to their surfaces. SBS tests were conducted using the Universal Tensile-Compression Test System (Instron 3382, USA). The tubule plugging efficiencies of the agents were examined on two dentin samples from each group by SEM. One-way analysis of variance (One-way ANOVA) was performed for statistical analysis of the data. For p<0.05, the results were considered statistically significant.
RESULTS: No statistically significant difference was found in any comparison between all the test groups (p>0.05). In SEM examinations, occluded dentinal tubules were observed more frequently in the groups where the applications were performed in combination with laser, compared to the application of the agents alone. In the propolis group too, the tubules were usually closed, as well as open dentin tubules.
CONCLUSIONS: Although combination applications of Er,Cr:YSGG Laser with Sodium Fluoride and Propolis showed greater dentin tubule plugging efficiency, these applications did not have a negative effect on the SBS of Clearfil Tri-S Bond Universal compared to the control group. The changes caused by the laser application on the dentin surface and the content of adhesive system may have prevented the SBS from being adversely affected.

AMAÇ: Bu in vitro çalışmanın amacı Sodyum Florid, Propolis ve Er,Cr:YSGG lazerin tek başına ve lazerle kombine uygulamalarının dentin tübülleri üzerindeki etkinliğinin SEM ile incelenmesi ve bu uygulamaların bir üniversal adezivin dentine makaslama bağlanma dayanımına (MBD) etkisinin incelenmesidir.
YÖNTEM: 72 adet çürüksüz daimi alt 3. molar dişin bukkal mine dokusu uzaklaştırılarak elde edilen dentin örnekleri rastgele altı gruba (n:12) ayrıldı: Kontrol, Sodyum Florid (Enamelast, Ultradent), Propolis (Fanus Propolis), Er,Cr:YSGG Lazer (Biolase, Waterlase), Enamelast-Er,Cr:YSGG Lazer, Propolis-Er,Cr:YSGG Lazer. Ajanların tek başına uygulandığı gruplarda dentin yüzeylerine ajan uygulanırken kombine gruplarda ajan uygulamasından sonra lazer uygulandı. Kontrol grubuna herhangibir uygulama yapılmadı. Örnekler 14 gün boyunca yapay tükrük içinde bekletildikten sonra yüzeylerine Clearfil Tri-S Bond Universal (Kuraray) ve kompozit rezin (Estelite Sigma Quick, Tokuyama) uygulandı. MBD testleri Universal Çekme-Basma Test Sistemi (Instron 3382, Amerika) kullanılarak yapıldı. Ajanların tübül tıkaç etkinlikleri, her gruptan iki adet dentin örneği üzerinde SEM ile incelenmiştir. Verilerin istatistiksel analizi için Tek Yönlü Varyans Analizi (One-way ANOVA) yapıldı. p<0.05 için sonuçlar istatistiksel olarak anlamlı kabul edildi.
BULGULAR: Tüm test grupları arasında hiç bir karşılaştırmada istatistiksel olarak anlamlı farklılık tespit edilmemiştir (p>0.05). SEM incelemelerinde, lazerin kombine uygulandığı gruplarda ajanların tek başına uygulanmasına göre tıkalı dentin tübüllerine daha sık rastlandı. Propolis grubunda da yer yer açık dentin tübülleri yanında genellikle tübüller kapalıydı.
SONUÇLAR: Er,Cr:YSGG Lazer'in Sodyum Florid ve Propolis'le kombine uygulamaları daha fazla dentin tübül tıkaç etkinliği göstermekle birlikte, Clearfil Tri-S Bond Universal'in MBD'si üzerinde kontrol grubuna göre olumsuz bir etki oluşturmamıştır. Lazer uygulamasının dentin yüzeyinde oluşturduğu değişimler ve kullanılan adeziv sistemin içeriği MBD'nin olumsuz etkilenmesini önlemiş olabilir.
