Farklı ışık kaynaklarının fissür örtücülerin bağlanma dayanımları üzerine etkisi

Amaç: Bu çalışmanın amacı, üç farklı rezin esaslı fissure örtücünün üç farklı ışık kaynağıyla polimerizasyonları sonrası süt ve daimi dişlere bağlanma dayanım değerlerinin araştırılmasıdır. Gereç ve Yöntemler: Pit ve fıssür örtücü olarak kullanılan 3 rezin esaslı materyalin (Fissurit FX, ClinproTM Sealant ve Teethmate F1) 3 farklı ışık kaynağı (Elipar Freelight 2=LED, Astralis 3=QTH ve Optilux 501=HQTH) ile polimerizasyonu sonrasında mine dokusuna bağlanma dayanımlarının belirlenmesi amacıyla 18 grup için çürüksüz 20 daimi azı dişi ve 20 süt azı dişi (toplam 360 diş) kullanıldı. Dişlerin kronları bukkal yüzeyleri açıkta kalacak şekilde silindir şeklindeki akrilik rezinlere gömüldü. Mine yüzeylerine 2 mm boyunda 2,9 mm çapındaki kalıp yerleştirildi. Fissür örtücü materyaller üretici firmanın tavsiyeleri doğrultusunda 20 sn süre ile ışıkla polimerize edildi. Distile su içerisindeki örnekler 37 °C’de 24 saat bekletildikten sonra makaslama bağlanma dayanımı testine tabi tutuldu. Veriler ANOVA, Tamhane ve Mann- Whitney U testleri ile istatistiksel olarak değerlendirildi (p=0.05). Bulgular: Daimi dişlerde hangi ışık kaynağı kullanılırsa kullanılsın, en yüksek bağlanma dayanımı değerini Fissurit FX materyalinin sergilediği gözlendi (p0.05). Ayrıca daimi dişlerdeki bağlanma dayanımının her üç fissür örtücü materyalde de süt dişlerinden yüksek olduğu belirlendi (p

Effect of different light-curing units on bond strength of fissure sealants

Background: The purpose of this study was to evaluate the shear bond strengths of three different resin-based pit and fissure sealants cured with three different light-curing units on primary and permanent teeth. Methods: A total of 360 samples were divided into eighteen groups (n=20) according to the combination of type of teeth (primary and deciduous teeth), three resin based pit and fissure sealants (Fissurit FX, ClinproTM Sealant and Teethmate F1) and three different lightcuring units (Elipar Freelight 2=LED, Astralis 3=QTH and Optilux 501=HQTH). Crowns of caries-free human permanent molar teeth and primary molar teeth were embedded in cylindrical acrylic resins leaving flat buccal surfaces uncovered. Two mm in height and 2.9 mm in diameter molds were placed on enamel surfaces and pit and fissure sealants polymerized according to manufacturer instructions for 20 seconds by light-curing units. After storage in distilled water at 37 °C for 24 hours, samples were submitted to shear bond strength test. The data were analyzed using ANOVA, Tamhane and Mann- Whitney U tests at p=0.05. Results: Fissurit FX material demonstrated the highest bond strength value in permanent enamel no matter which light source was used (p<0.05). It was found that light sources did not have an effect on the bond strength values of pit and fissure sealants (p>0.05). Besides, it was observed that bond strengths of all three pit and fissure sealants were higher in permanent enamel than deciduous enamel (p<0.05). Conclusion: The pit and fissure sealants with higher filler content seem a preferable alternative to have low filler content pit and fissure sealants.
