To investigate the bonding of tooth-colored indirect restorations to cervical dentin, shear bond strengths of bonded resin inlays to cervical dentin and mid-coronal dentin were investigated and compared. Indirectly fabricated composite inlays (Estenia) were cemented with a dual-cured resin cement (Panavia Fluoro Cement II) to either cervical or mid-coronal dentin. Resin cement was cured with or...
STATEMENT OF THE PROBLEM Increasing the thickness of the veneering porcelain may affect the polymerization of resin cements. Incomplete polymerization of resin cements can lead to compromised quality of restoration and decrease the longevity of indirect restorations. PURPOSE This study sought to assess the effect of IPS Empress porcelain thickness on the degree of conversion of light-cure and...
OBJECTIVE To determine the light intensity emitted by light curing units (LCUs) and its effect on the cure characteristics of composites polymerised with it. DESIGN A laboratory based cross sectional study. SETTING Public and private dental clinics in Nairobi, Kenya. RESULTS Thirty five (42.17%) LCUs produced light of intensity ≤300mWcm⁻² while 43 (51.8%) LCUs had their intensities betwee...
Background and Aim: The efficiency of disinfecting materials and procedures in removal of contamination from dental surfaces and equipments is essential. In authors' previous study, daily use of 2:100 dilution of 5% sodium hypochlorite in water and disposable covers were recommended since HBV contamination was found on semi-critical parts of the operative dentistry department. The aim of this s...
PURPOSE Adequate polymerization is a crucial factor in obtaining optimal physical properties and a satisfying clinical performance from composite resin materials. The aim of this study was to evaluate the polymerization efficiency of dual-cure resin cement cured with two different light curing units under zirconia structures having differing thicknesses. MATERIALS AND METHODS 4 zirconia discs...
زمینه و هدف: یکی از معضلات علم دندانپزشکی، در دندانپزشکی ترمیمی ریزنشت است که باعث تلاش برای یافتن مادهای با کمترین میزان ریزنشت و راهکارهایی برای کاهش ریزنشت شده است. هدف این مطالعه مقایسه لابراتوری میزان ریزنشت ترمیم های کامپوزیتی در بازسازی کامل دندانی با استفاده از Clearfil Photo Core-Light Cure (Kuraray , ژاپن)در دو روش قراردهی تودهای و قطعهای است. روش بررسی:<...
