Comparison of microleakage of nanofilled resin composites cured with different light curing units

Abstract

Comparison of microleakage of nanofilled resin composites cured with different light curing units Aim of this study is to evaluate the effect of two different light curing units used to cure resin composites with different monomer structures on microleakage of Class II box cavities with restoration margins ending in dentin in vitro. Ninty extraceted sound human third molar teeth were used. 180 cavities with mesial and distal box cavities were prepared on 90 teeth. For each resin composite and curing unit 10 teeth were restored. Microleakage values were compared with Kruskal-Wallis and Mann-Whitney U tests p

Abstract

Nanodoldurucu øçeren Kompozitlerin FarklÕ IúÕk CihazlarÕ ile MikrosÕzÕntÕ Yönünden KarúÕlaútÕrÕlmasÕ Bu çalÕúmanÕn amacÕ farklÕ doldurucu özelliklerine, farklÕ monomer yapÕsÕna sahip kompozit rezinlerin ve kompozit rezinlerin polimerizasyonunda kullanÕlan iki farklÕ ÕúÕk cihazÕnÕn, restorasyon sÕnÕrÕ dentinde sonlanan SÕnÕf II kutu kavitelerdeki mikrosÕzÕntÕya olan etkilerini in-vitro olarak incelemektir. ÇalÕúmamÕzda 90 adet çürüksüz insan molar diúi kullanÕldÕ. Bu 90 diúe mesial ve distal olmak üzere 180 SÕnÕf II kutu kavite açÕldÕ. Her bir kompozit rezin ve ÕúÕk cihazÕ için 10 örnek olacak úekilde gruplar hazÕrlandÕ ve restorasyonlar yapÕldÕ. Boya penetrasyon tekni÷i ile sÕzÕntÕ testi uygulandÕ. MikrosÕzÕntÕ testinden elde edilen veriler Kruskal –Wallis ve Mann- Whitney –U testleriyle de÷erlendirildi p
