Comparison of dimetral tensile,flexural,and compressive strengths of five core buıld-up materials

Öz:

Bu çalışmanın amacı, beş farklı kor materyalinin üç mekanik özelliği; çapsal germe direnci, sıkıştırma direnci ve bükülme direncini değerlendirmektir. Bu çalı şma için, ışıkla sertleşen hibrid kompozit rezin (President, Light cure Dynamic Universal hibr/'t Compozit, München, Germany), rezin modifiye cam iyonomer (Vitremer, 3M Dental Products, St. Paul MN, USA), amalgam(Cavex Avalloy, Harlem, Hollanda), cam iyonomer (Logofil, D-Dental Alten, Alien Walde, Germany) ve compomer (Dyract AP) materyalleri kullanıldı. Çapsal germe direnci, sıkıştırma direnci ve bükülme direnci testi için toplam 120 örnek American Dental Association 27 nolu spesifikasyonuna göre hazırlandı. 6mm yüksekliğinde ve 3mm çapında 40 silindirik örnek, çapsal germe direnci için ve 25X2X2 mm boyutlarında 40 örnek ise bükülme direnci testi için hazırlandı. Tüm kor materyalleri üretici firma önerileri doğrultusunda 23.0 +/- 1.0 °C'de hazırlandı. Testler Hounsfield çekme-sıkıştırma makinesinde, bükülme ve sıkıştırma gerilim testleri 0.5 mm/dak. ve çapsal gerilim testi için 1 m m/dak. başlık hızı ile yapıldı. İstatistiksel değerlendirme için varyans analizi kullanıldı. Her bir materyal için Çapsal germe direnci, sıkıştırma direnci ve bükülme direncine ait ortalama ve standart sapma değerleri hesaplandı. Çalışmanın sonuçlarına göre Çapsal germe direnci, sıkıştırma direnci ve fleksural gerilim direnci açısından Kompozit resin (President) ve Amalgam (Cavex avalloy), diğer test edilen materyallere göre önemli derecede yüksek bulundu. (p<O.O0l). Diğer yandan cam iyonomer esaslı materyallerin Çapsal germe direnci, sıkıştırma direnci ve bükülme direnci resin kompozit, kompomer ve amalgama göre düşük bulundu.

The purpose of this laboratory investigation was to evaluate three mechanical properties; the compressive, diametral tensile and flexural strengths of five different core build-up materials. In this study, a light-actived Hybrid composite resin (President), resin modified glass ionomer (RMGIC) (Vitremer), amalgam (Cavex avalloy), glass-ionomer (GIC) (Logofil) and compomer (Dyract AP) restorative materials were used. 120 samples were prepared according to American Dental Association specification No. 27 for testing diametral tensile strength (DTS), compressive strength (CS) and flexural strength (FS). Forty specimens were prepared in cylindric molds (6 mm in height, 3 mm in diameter) for the CS measurements and forty specimens (3 mm in height, 6 mm in diameter) for diametral tensile strength (DTS). Forty specimens were prepared (25X 2X2 mm) for the FS measurements. All cores materials were prepared according to manufacturers instruction at a temperature of 23.0 +/-1.0 degrees C. Haunsfieldpress and pull machine was used for compressive and flexural strength and the module were determined at a crosshead speed of 0.5 mm/min. Diametral testing was carried out at 1 mm/min. Analysis of variance was used for statistically evaluation. Mean compressive, diametral tensile and flexural strengths with associated standard deviations were calculated for each material. The results of this study indicated that the diametral tensile strength, flexural strength and compressive strength of the resin composite (President) and amalgam material were significantly higher than the other tested materials (p<0.001). On the other hand, the diametral tensile strength, flexural strength and compressive strength of glass ionomer based materials (Logofil, Vitremer) were statistically lower than for resin composites, compomer and amalgam.
