Öğe Efficiency of different light sources to polymerise composite material(MANEY PUBLISHING, 2011) Yondem, I.; Usumez, A.; Gunduz, B.; Inan, O.The aim of this in vitro study is to examine the polymerisation efficacy of three different polymerisation units through simulated three different ceramic restorations (5 mm in diameter and 2 mm in height) by determining the degree of monomer conversion of a composite luting material. The curing efficiency was observed with Fourier transform infrared micromultiple internal reflectance spectroscopy after 24 h of polymerisation. The degree of conversion was calculated as a percentage of experimentally polymerised versus maximally polymerised composite. The degree of conversion values varied with the light source (light emitting diode, high intensity halogen and conventional halogen) (p<0.05) and the ceramic system (Cercon, IPS Empress 2 and Cerec) (p<0.05).Öğe Sealing properties of four different post systems.(INT AMER ASSOC DENTAL RESEARCHI A D R/A A D R, 2003) Ozturk, A.
