Hızlandırılmış yaşlandırma sonrası kompozit rezin simanların

Amaç: Bu çalışmada; farklı PLV’ler ve kompozit rezin simaların hızlandırılmış yaşlandırma sonrası polimerizasyon dereceleri incelendi. Gereç ve yöntem: Bu amaçla, PLV’ler dört farklı porselen materyali (IPS Empress 2, VitaBlock Mark II, Vitadur alpha ve Ceramco 3) ile iki farklı kalınlıkta (0,5 mm ve 0,7 mm) hazırlandı. Hazırlanan örnekler iki ışıkla polimerize rezin siman (light Variolink II, Ivoklar Vivadent, Rely X Veneer, 3M Espe) ve bir dual polimerize rezin siman (Variolink II, Ivoklar Vivadent) ile yapıştırıldı ve elde edilen tüm örneklere hızlandırılmış yaşlandırma işlemi uygulandı. Bu işlemden önce ve sonra örneklerin polimerisazyon derecelerini belirlemek için Vicker’s sertlik testi yapıldı Porselen sistemlerinin, porselen kalınlığının ve rezin sistemlerinin sertlik değerlendirmesi için çok yönlü varyans analizi uygulandı. Sonuçlar: Porselen sistemleri arasında polimerisazyon değerleri açısından yaşlandırma öncesi ve sonrasında fark istatistik olarak değerlendirildi. Porselen sistemleri arasında; hızlandırılmış yaşlandırma yapılmadan önce sertlik değerleri açısından fark istatistik olarak anlamsızken (p=,430), hızlandırılmış yaşlandırma sonrası sertlik değerleri arasında fark istatistik olarak anlamlıdır (p

Effect of various porcelain laminate veneers on polimerization degree of luting resin cements after accelareted aging

Background: At the current study, degree of conversion after accelerated aging of PLV’s luted by composite resin luting cement were investigated. Methods: PLV’s were fabricated from four different materials (IPS Empress 2, VitaBlock Mark II, Vitadur alpha and Ceramco 3), and two different thicknesses (0,5 mm and 0,7 mm) for each material. Prepared samples were exposed to accelerated aging and two lightcured luting resin cements (light Variolink II, Ivoklar Vivadent, Rely X Veneer, 3M Espe) and a dual-cured luting resin cement (Variolink II, Ivoklar Vivadent) were used to bond. Vicker’s microhardness degree of samples were recorded before and after this procedure. Multipleway analysis of variance was used to evaluate the micro hardness in between each porcelain system, for different porcelain thickness and different resin systems. Result: Polymerization values of porcelain systems were evaluated to statistically before and after accelerated aging. While the differences between microhardness values of porcelain systems before accelerated aging were not statistically significant (p=430), it was statistically significant after accelerated aging (p<0,05). However, the differences between microhardness values of composite resin systems were statistically significant both before and after accelerated aging (p<0,05). Conclusions: In the limitation of this study, when composite resin cement polymerization evaluated by the samples which were prepared with Ceramco 3 porcelain by light polymerized Rely X Veneer composite cements were found more succesfull than the other systems.
