The purpose of this study was to investigate the thermal behavior of three dental composite resins(Aelitefil, Hipoline, Photo Clearfil Posterior) currently used in dental clinics as well as to find out a correlation between diametral tensile
strengths
and thermal behaviors according to the light curing time. After making specimens 15, 30, 45 and 60 seconds light cured respectively, those were measured in diametral tensile strengths and analyzed by Differential Scanning Calorimetry, and by
measuring
the weight of specimens before and after thermal analysis and calculating the proportion of filler in composite resin, following results were obtained.
