Comparison Of Different Kinds Of Light Cure Flowable On Mechanical Strength

Purpose: Compare Clearfil Majesty LV, Venus Flow, Tetric N-Flow,Estelite Flow Quick, Esthet-X five resin curing light fluid Flow of flexural strength,compression strength, polymerization shrinkage, strength for clinical operation providecertain theoretical basis for the selection of materials.Methods:Using electronic universal testing machine test Clearfil Majesty LV,Venus Flow, Tetric N-Flow, Estelite Flow Quick, Esthet-X five resin curinglight fluid Flow of flexural strength, compression strength; Use JMS-6330-lvscanning electron microscope (sem) polymerization shrinkage of the material was tested.Test results using SPSS13.0software to analysis of variance and SNK LSD ALPHA(0.05) testing method for statistical analysis.Results: Flexural strength, according to the comparison results Clearfil Majesty LV flexural strength result was203.05±17.55MPa, the Venus Flow,Tetric N-Flow, Estelite Flow Quick, Esthet-X Flow four kind of uv-curable fluidresin material, no statistical difference between the other materials.Comparison resultsshow that the compression strength Clearfil Majesty LV compression strength was417.85±29.41MPa, the Venus Flow, Tetric N-Flow, Estelite Flow Quick, Esthet-X Flow four kind of uv-curable fluid resin material, no statistical differencebetween the other materials. Results show that the polymerization shrinkage degreesTetric N-Flow and Estelite Flow was statistically difference between the Quick,there is no significant difference between other groups.Conclusion: Test by various mechanical properties of the composite resin isdifferent, each have advantages and disadvantages, Clearfil Majesty LV itsmechanical strength is superior than other materials...
