Evaluation of Microhardness of Different Posterior Composite Resin Materials

Year 2008, Volume: 35 Issue: 2 - Volume: 35 Issue: 2, 61 - 66, 01.05.2008

Abstract

The aim of this study was to compare the microhardness of a new posterior composite resin, Clearfil Majesty Posterior Kuraray , with two different posterior composite resins; Filtek Silorane 3M-ESPE and Quixfil Dentsply . Ten specimens of each of the three materials totaly 30 were fabricated using a plexiglas mold of 9 mm in diameter and 1,5 mm in depth. All of the materials were polymerized according to the manufacturer’s instructions. After the polymerization strips were removed and stored at 37ºC in distilled water for 24 hours. Specimens were subjected to surface microhardness tester Digital Display Microhardness Tester HSV-1000 with 100 g force applied for 20 s on the surface. Three indentations were made and measured on each specimen and an average value was determined from each specimen. Statistical analysis was performed using one-way ANOVA and Tukey’s test. There were statistically significant differences among the microhardness of the composite materials. The ranking from least to most were as follows; Filtek Silorane < Quixfil < Clearfil Majesty Posterior. The microhardness of Clearfil Majesty posterior was higher than the posterior composite materials tested.

Hazırlanan örnekler üretici firmalarınönerilerine uygun olarak polimerize edildi ve37ºC’de distile su içerisinde 24 saat bekletildi.Kompozit disklere yüzey mikrosertlik test cihazında Digital Display Microhardness Tester HSV–1000 20 sn süre ile 100 gr yük uygulandı. Her örnektenüçer defa yüzey sertlik ölçümü alınarak, bu üçölçümün ortalaması her bir örnek için tek bir değerolarak kabul edildi. İstatistiksel analizler tek yönlüANOVA ve Tukey testi ile yapıldı.Grupların mikrosertlik değerleri arasındakifarkın istatistiksel olarak anlamlı olduğu belirlenmiştir. Materyallerin mikrosertlik değerlerininküçükten büyüğe doğru sıralaması şu şekildedir;Filtek Silorane < Quixfil < Clearfil MajestyPosterior. Clearfil Majesty Posterior’un yüzeymikrosertlik değerleri, test edilen diğer iki posteriorkompozite göre daha yüksektir
