Özet
Bu çalışmanın amacı farklı tekniklerle yapıştırılmiş postların mikrosızıntılarım radyo-kimyasal difuzyon tekniği ile karşılaştırmalı olarak incelemektir. Çalışmada kron kısımları uzaklaştırılmış 33 adet yeni çekilmiş tek köklü diş kullanıldı. Kök kanalları genişletildikten sonra dişler herbir grupta 10'ar örnek olacak şekilde 3'e ayrıldı. Üç diş ise pozitif kontrol olarak kullanıldı. Köklerin 6 mm'lik koronal kısımları kalacak şekilde apikal bölgeleri elmas disk ile kesildikten sonra, kökler polyester disklere gömüldü. Post yuvalan hazırlandıktan sonra, postlar 1. grupta çinko fosfat simanla, 2. grupta kompozit ile, 3. grupta dentin bağlayıcı ajanın tatbikinden sonra kompozitle yapıştırıldı. Polyester diskler U şeklindeki cam boruların sağ koluna O-ring'ler kullanılarak yerleştirildi. U borunun sağ koluna distile su, sol koluna ise Cr1 solüsyonları eşit seviyede konuldu. Bir hafta sonra yapılan ölçümlerde distile suya geçen Cr ' miktarı ölçülerek sızıntının miktarı kantitatif olarak belirlendi. Alınan sonuçlar istatistiksel olarak değerlendirildiğinde l .grup ve 3.grupta, 2. gruba oranla belirgin biçimde daha az sızıntı tespit edildi (p<0.05).
The purpose of this study was to investigate the microleakage along the posts which were cemented with different techniques using a radiochemical diffusion technique comparatively. Thirtythree freshly extracted, single rooted teeth were used following the crowns were removed. After the root canals were hand-instrumented, they were divided into 3 experimental groups of 10 each. Three teeth were used as positive control. After the apical portions of the roots were removed having a 6 mm of coronal portion left, they were embedded into the pol-yester discs. After post preparations, post dowels were cemented with zinc phosphate cement (in group 1); composite resin (in group 2) and composite resin after application of a dentin bonding agent (in group 3). Then the polyester discs were clamped between the O-rings in the right-hand arm of the U-shaped diffusion apparatus. Distilled water was added to the right-hand arm and Cr51 solution to the left-hand arm of the apparatus until the level of the solutions were equal. After 1 week the amount of Cr"1 diffused in distilled water was measured. According to measurements; significantly less leakage was observed along the post dowels in group 1 and group 3, when compared group 2 (p<0.05).
