The Effect of Water Sorption and Solubility of Different Types of Conventional and Resin-Modified

Abstract

The aim of this study, was to compare thewater sorption and solubility of two traditional glassionomer cements GIC and one resin-modifiedglass ionomer cement RM GIC material. The traditional GIC dental materials which were CeramFil PSP Dental, England and Ionofil VocoGmbH, Germany and the RM GIC dental materialwhich was Rely-X 3M Dental Products, St Paul,USA were used in study. All specimens were prepared according to the manufacturer’s instructionsand then subjected to water sorption and solubilitytests based on the ISO 4049 and ADA No.8 requirements. In the study, weight changes of specimens ofthree materials were determinated after waterimmersion for 1 and 7 days and the results werecompared. Values were analyzed with two-wayANOVA and Duncan’s test at a 0.01 significancelevel. Results showed that, the Rely-X specimenshad significantly less water sorption and solubilityvalues than other two traditional GIC specimensafter water immersion for 7 days and the Ionofilspecimens had most water sorption and solubilityvalues than specimens of other two materials afterwater immersion for 7 days. There were not significantly differences statistically between specimensof three materials after water immersion for oneday

FARKLI TİPLERDEKİ GELENEKSEL VE REZİN-MODİFİYE CAM İYONOMER SİMANLARIN SU EMİLİMİ VE SUDA ÇÖZÜNÜRLÜĞÜ

Abstract

Bu çalışmanın amacı, iki geleneksel camiyonomer siman CİS ve bir rezin-modifiye camiyonomer simanın RM CİS ; su emilimlerinin vesuda çözünürlüklerinin araştırılması vekarşılaştırılmasıdır. Çalışmada geleneksel CİSmateryaller olarak, Ceram Fil PSP Dental,England ve Ionofil Voco GmbH, Germany veRM CİS materyal olarak ise Rely-X 3M DentalProducts, St Paul, USA kullanıldı. Tüm örnekler,üretici firmaların talimatları doğrultusundahazırlandı ve ardından ISO 4049 ve ADA No.8kriterleri doğrultusunda su emilimi ve sudaçözünürlük testlerine tabi tutuldu. Çalışmada, her 3materyale ait örneklerin ağırlıklarındaki değişiklikler, suda 1 ve 7 gün bekletildikten sonradeğerlendirildi ve karşılaştırıldı. Değerler iki-yönlüANOVA ve Duncan testleri kullanılarak istatistiksel olarak analiz edildi. Sonuçlar; 7 gün suda bekletilmenin ardından, Rely X örneklerin, diğer ikigeleneksel CİS örneklere nazaran belirgin orandadaha az su emilimi ve suda çözünürlük değerleriverdiğini, İonofil örneklerin ise, 7 gün suda bekletilmenin ardından en fazla su emilimi ve sudaçözünürlük değerleri verdiğini gösterdi. 1 gün sudabekletilmenin ardından her 3 materyale ait örnekler arasında ise istatistiksel olarak belirgin farklılıkbulunmadı
