Year 2005, Volume: 32 Issue: 2 - Volume: 32 Issue: 2, 91 - 98, 01.05.2005

Abstract

The aim of this in vitro study was to comparethe surfaces hardness of a nano-hybrid compositeresin material by using different light curing units.Disc-shaped composite specimens 10 x 2 mm weremade using stainless steel mold. The resin materialswere placed into the holes and covered by transparent mylar strips at the top and bottom. The material was compressed at both ends by glass slides 1mmthick. The light source tips of the curing units werepositioned directly over the mylar strip. The specimens were polymerized for Group 1: halogen lightcuring unit LCU 600 mW/cm2 with 40 seconds,for Group 2: light-emitting-diode LED LCU 400mW/cm2 with 40 seconds, for Group 3: LED LCU 1000 mW/cm2 with 10 seconds and for Group 4:LED LCU 1000 mW/cm2 with 20 seconds. Afterlight curing the specimens were kept in 37°C distilled water for 24 hours. Three hardness readingson the top and bottom of each specimen were takenwith Knoop Hardness Measurements. Statisticalmeasurements were made by using one-way analysis of variance ANOVA and Tukey test. LED 1000 mW/cm2 with 10 seconds LCU in group 3showed lower top and bottom surfaces. No statistical differences showed any of the other groups bothtop and bottom surfaces P>0.05 . The top surfacesof the all specimens found high values than bottomsurfaces

Abstract

Bu in vitro çalışmanın amacı nano-hibrit birkompozit rezinin farklı ışık cihazları ile polimerizeedilmelerinin yüzey sertliğine olan etkilerininkarşılaştırılmasıdır. Kompozit örnekler, disk şeklindeki 10 x 2mm paslanmaz çelik kalıplar yardımıylahazırlandı. Örnekler çelik kalıplara alt ve üst yüzeylerinde şeffaf bant olacak şekilde yerleştirildi.Daha sonra 1mm kalınlığındaki cam plakalararasında parmak basıncıyla sıkıldı. Örneklerinpolimerizasyonu için ışık cihazlarının ucu direktolarak şeffaf bant üzerinden uygulandı.Polimerizasyonlar 1. Grup için halojen ışık cihazı 600 mW/cm2 ile 40 sn süreyle, 2. Grup içinlight-emitting-diode LED ışık cihazı 400mW/cm2 ile 40 sn süreyle, 3. Grup için LED ışıkcihazı 1000 mW/cm2 ile 10 sn süreyle ve 4. Grupiçin LED ışık cihazı 1000 mW/cm2 ile 20 snsüreyle gerçekleştirildi. Polimerize edilmiş kompozit örnekler daha sonra 37 °C de 24 saat distilesu içerisinde bekletildi. Örneklerin alt ve üstyüzeylerinden üçer defa Knoop sertlik cihazı ileölçümleri yapıldı. İstatistiksel değerlendirme tekyönlü varyans analizi ANOVA ile yapıldı vegruplar arası farklılıklar Tukey testi ile belirlendi.En düşük alt ve üst yüzey sertlik değerleri 3.Gruptaki 10 sn süreyle uygulanan LED 1000mW/cm2 ışık cihazı için elde edildi. Diğer polimerizasyon grupları arasında hem alt hem de üstyüzey sertlik değerleri için istatistiksel bir farkbulunmadı P>0.05 . Tüm örneklerin üst yüzeysertlikleri, alt yüzey sertliklerinden daha yüksekbulundu
