Abstract (2. Language): 
Smear layer, which occurs while the cavity preparation, doesnft forms a stable substructure in connection to the tooth surfaces. Microlcakage occurs by the time by dissolving of the layer between restorative materia! and Lhe teeth. The purpose of this study was to evaluate the microlcakage of the different conditioners applied at the class I cavities prepared at the dimensions of which were 4x3x2 mm5 on the extracted primary molar teeth. For this reason, Fuji Cavity Conditioner, maleic acid 10%, Phosphoric acid 35%, hydrogen peroxide 3% applied to the cavities and restored with the Ftıji IX restorative glass ionomer cement. Then restorations thermocycled, placed in 0,5% basic-fuchsion dye for 24 hours and by taking the sections in the direction of mesiu-disial bum the teeth was evaluated lor the microleakagc under stereomicroscopc. The obtained microleakagi: disruption was: Phosphoric acid - Fuji Cavity Conditioner > Maleic acid 10% > Hydrogen Peroxide > Control Group. Kruskal Wallis was applied to the obtained microleakage score disruptions. As a result of this analysis, the difference?; between the groups were found to be statistically significant (p<0,05). Final Iv, in in-vitro conditions Phosphoric acid and Fuji Cavity Conditioner conditioners applied to the class I cavities rcslored with high viscosity glass lonomcr cement, determinate lu eliminate the microieakage.

Abstract (Original Language): 
Kavite hazırlık işlemleri sırasında meydana gelen smear tabakası, resioraLif materyalin diş sert dokularına bağlanmasında stabi! bir alt yapı oluşturmaz vc bu tabakanın zaman içinde çözünmesine bağlı olarak da zamanîa diş ile restoratif material arasında rn.ikrosi7.inh meydana gelir. Bu çalışmanın amacı, çekilmiş KÜL a/.ı dişlerinde 4x3x2mm^ boyutlarında standart şekilde hazırlanmış olan sınıf I kavitelere, farklı uygun duruma geüriei ajan uygulamalarının mikrosızıntı üzerine etkilerinin değerlendirilmesidir. Bu amaçla, hazırlanmış olan kavitelere, Fuji Cavity Conditioner, %10'luk maleik asit, %35'lik fosforik asit ve %3'lük Hidrojen Peroksit uygulanmış ve kavi-teler Fuji IX restoratif cam-ionomer siman ile restore edilmiştir. Daha sonra, restorasyonlar ısı banyosu işlemine tabi tutulmuş, %0,5'lik bazik fuksin boyasında 24 saat bekletilmiş ve mesio-distal doğrultuda kesitler alınarak sreromik-roskop alünda sızıntı yönünden değerlendirilmiştir. Meydana gelen mikrosızıntı dağılımı Fosforik asit = Fuji Cavity Conditioner > %10'luk Maleik asit > Hidrojen Peroksit > Kontrol grubu şeklinde olmuştur. Elde edilmiş olan mikrosızıntı dereceleri dağılımına uygulanan Kruskal Wallis varyans analizi sonucunda, gruplar arasındaki farklılığın istatistiksel olarak anlamlı (P<0,05) olduğu gözlemlenmiştir. Sonuç olarak, in vitro şartlarda yüksek viskozitcli cam-ionomer siman ile restore edilmiş olan sınıf I kavite-lerde fosforik asit veya Fuji Cavity Conditioner uygun duruma getirici uygulamalarının mikrosi7intıyı ortadan kaldırdığı tespit edilmiştir.
