Abstract (2. Language): 
This study was realised to compare m point of the porosity of acrylic resins which are prepared in various thickness and polimerised by using different methods. 45 samples from each ol" three different acrylic resins were prepared. Total 135 acrylic resin sampler, having the dimensions of 20x20x2 mm, 20x20x4 mm and 20x20s.6 mm were prepared with various polimeri.sation methods. After the finishing and polishing procedures, they were immersed m Indian ink. They were evaluated in point of external porosity by using optic microscope. Than hall of the thickness of each sample were abrused. These samples were evaluated in view of internal porosity after they were painted with the same method. Datas obtained were evaluated with Kruskal-Wallis variant of analysis methods. It is statistically found that polimcrisalion method and the thickncsi are very important and the type of acrylic resin is not important

Bu çalışma, farklı yöntemlerle polimerice edilen değişik kaİ!îi!ıklafd?.ki akriiik reziillerin pomy.ite atçısından karşılaştırılması amacıyla yapıldı. Üç farklı akriiik recinin herbirinden, 45 adet olacak şekilde toplam 135 akrilîk rezin örnek, çeşitli polime-rizasyoıı yöntemleriyle 20x20x2 mm,, 20x20x4 mın. ve 20x20x6 mm. boyutlarında hazırlandı. Tesviye ve cilalama işlemlerini takiben, çini mürekkebine atılarak bekletildi. Tşık mikroskobunda, ekstcrnal porozite açısından değerlendirildi. Daha sonra yarıya kadar ağındırılıp, İnim, 2mm ve 3 mm. kalınlığa getirilen örnekler, aynı şekilde boyandıktan sonra internal porozite açısından değerlendirildi. Hide edile n verilerin değerlendirilmesinde, Kruskal-Wallis varyans analiz yöntemi kullanıldı. Akriiik tipinin önemli almadığı, polimeri/asyon tekniği (internal porozitede p<O.0OI, ekstcmal porozitede p< 0-01) ve kalınlığın (p<0.00l) ise çok önemli oldngıı istatistiksel olarak tespit edildi.
