FARKLI SIVILARIN AKRİLİK REZİNLERİN YÜZEY SERTLİKLERİNE ETKİSİNİN İNCELENMESİ

Amac: Bu calismada, farkli sivilarin akrilik rezinlerin yuzey sertlik degisimlerine etkisinin incelenmesi amaclanmistir. Gerec ve Yontem: Uc farkli akrilik rezinden hazirlanan 75 adet ornek rastgele bes gruba ayrilarak degisik sivilarda yedi gun bekletildi. Daha sonra Vickers sertlik cihazi ile yuzey sertlik olcumleri yapildi. Elde edilen verilerin degerlendirilmesinde iki yonlu varyans analizi (ANOVA) kullanildi. Bulgular: En fazla yuzey sertlik degeri (184.62 VHN) herhangi bir sivida bekletilmeyen isi ile polimerize edilen akrilik rezin orneklerde, en az yuzey sertlik degeri ise (132.24 VHN) agiz gargarasinda bekletilen otopolimerizan akrilik rezin orneklerde tespit edildi. Sonuc: Farkli sivilarin akrilik rezinlerin yuzey sertligini istatistiksel olarak anlamli derecede etkilemedigi goruldu. Anahtar Kelimeler: Yuzey sertligi, farkli sivilar, akrilik rezi INVESTIGATION OF THE EFFECT OF DIFFERENT SOLUTIONS ON SURFACE HARDNESS OF ACRYLIC RESIN ABSTRACT Aim: The aim of this study was to investigate the effect of different solutions on surface hardness of acrylic resin. Material and Methods: 75 specimens were prepared from three different acrylic resins randomly divided into five groups and stored in different solutions for seven days. The surface hardness test was performed with Vickers hardness test machine.  The statistically analysis of obtained data were performed by two-way analysis of variance test (ANOVA). Results: The result of two-way analysis of variance test showed that the highest Vickers Hardness value (184.62 VHN) was identified in control group for heat-curing acrylic resin, the lowest Vickers Hardness value (132.24 VHN) was identified stored in mouthwashes for self-curing acrylic resin. Conclusion: The different solutions were not statistically affect the surface hardness of denture base materials. Key Words: Surface hardness, different solutions, acrylic resin
