Abstract (2. Language): 
The dim of this study was la compare the bond strength of acrylic resin teeth treated in various ways to heat-cured acrylic base resin material. A total of 64 cylindrical wax specimens with 20mm in length and 9mm m diameter were produced and they were reduced to 7 mm diameter in order thai a butt-joint existed at the interface of acrylic denture base resin and aruTicjal tooth. Sixty-four acrylic resin artificial teeth were inserted into the centet of these cylindrical was specimens as their incised edges parallel to the floor and their long axis vertical to the floor, Specimens were then divided randomly into 4 groups containing equal number of specimens. Subsequently, all samples were fla.sk.ed. The ridge; lap •surface! of acrylic teeth were painted with the methyl methacrylate monomer (MMA) in Group 2, with a bonding agent in Group 3, and both with MMA and bonding agent in Group 4 before packing the acrylic base resin material. In Group 1, no surface treatment was applied and this group was used as the control group. One sample from each group was excluded to inspect the interface between the acrylic base material and acrylic tooth interface under Scanning Electron Microscope. Remaining specimens were coirspressively loaded under 135° angle and 1.5 mm/min crosshcad speed until failure. The data obtained were analyzed statistically using one way ANOVA test. ANOVA reveals statistically significant differences between the groups (P<0,000), Post-Hoc multiple comparisons were made with Tukey's lest. Ttikey's multiple comparisons reveal a significant increase in acrylic tooth bund strength in comparison with the control group. It is recommended that different surface treatments on the ndge lap surfaces of acrylic teeth before packing acrylic base material were found helpful to maintain a reliable bond between the acrylic teeth and the acrylic resin base material.
Abstract (Original Language): 
Bu çalışmanın amacı, çeşitli yüzey işlemleri uygulanmış akrilik rezits dişlerin ısı ile polimerize olan akrilik rc/in kaide materyaline bağlanma dayanımını değerlendirmektir. Bu amaçla; 9mm çapında ve 20mm boyunda 64 adet sililldirik mum örnek ha/.irîanmış ve akrilik kaide rezini ile diş yüzeyinin devamlılık sağlayacak şekilde birleşimini sağlamak için örnek çapı 7ırurT ye dUşUnjJmuştüY. Örnekler, rastlantısal yolla her bin eşit sayıda örnek içeren 4 gruba ayrılmıştır (n=16). Daha sonra örnekler muflalan-mıştır, Akrilik rezin dişlerin bağlanma yüzeyleri Grup T de metilmctakrilat (MMA) monomeri ile, Grup 3' te bağlayıcı ajan ile ve Grup 4' tc MMA vc bağlayıcı ajan ile akrilik tepme işleminden önce işlernlenmiştir. Grup 1' deki örneklere hiçbir uygulama yapılmamıştır ve bunlar kontrol olarak kullanılmıştır. Her bir gruptan bir örnek, akrilik rezin kaide materyali-akrilik diş ara yüzünün mikroskobik değerlendirmesi için ayrılmıştır. Mikroskobik değerlendirme için, Taramalı Elektron Mikroskobu' ndan (SFiM) yararlanılmıştır. Örneklere; 135°' lit açı ile 1,5 mın/dak başlık hızında, kırılma gerçekleşene kadar kuvvet uygulanmıştır. Tek yönlü varyans anali/i, gruplar arasında istatistiksel olarak anlamlı farklılık bulunduğunu göstermiştir (P< 0,000). Gruplar arasındaki farklılığın kaynağını göstermek için uygulananTukey HSD çoktu karşılaştırma testi ise; yüzey iş-lcmi uygulanmış akrilik re/.in dişlerin uygulanmamış olan dişlerden daha fazla bağlanma dayanımına sahip olduklarını göstermiştir. Akrilik tepme işleminden önce akrilik rezin dişlerin bağlanma yüzeylerinin işlcmlcnmesmin yararlı olduğu görülmüştür.
