Physical Properties of Three Different Types of LC Composite Resins

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), flexural 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, flexural 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 significant statistical differences were observed in the values of the compressive strength, diametral tensile strength and depth of cure tests (p<0.05), no significant variance was found in the results of the flexural 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 Definite scored highest on the depth of cure test.
