Abstract

Objectives: The aim of this study was to determine physical properties of three different types of composite resins: Point 4 (microhybrid), Solitaire 2 (packable) and Definite (ormocer). Materials and Methods: In the physical section of this study, 10 samples for each of the following tests were prepared from each of the three restorative materials according to standard protocols: compressive strength test (ADA 27), diametral tensile strength test (ADA 27), fl exural strength test (ISO 4049) and depth of cure test (ISO 4049). The data were analyzed using Kruskal Wallis and Mann Whitney-U tests. Results: The compressive, diametral tensile strength, fl exural strength, depth of cure test values respectively of the materials were: Point 4 (202.49, 47.12, 93.09, 4.74); Solitaire 2 (248.92, 59.74, 92.97, 4.12); and Definite (174.73, 50.82, 103.15, 5.25). While signifi cant statistical differences were observed in the values of the compressive strength, diametral tensile strength and depth of cure tests (p<0.05), no signifi cant variance was found in the results of the fl exural strength test (p>0.05). Conclusion: According to the results of the compressive strength and diametral tensile strength tests, Solitaire 2 received the highest value, whereas Defi nite scored highest on the depth of cure test.
