Properties of New Resin-Based Materials Incorporated with Fluorine-Cross-Linked Polymer
Objectives: Fluorine-containing compounds have been used in order to increase hydrophobicity and decontamination effects of dental materials. The aim of this study was to evaluate mechanical and physical properties of experimental resin-based materials incorporated with 0, 2, 5, 10, 20 and 30 wt% of fluorine-cross-linked polymer (FCP). Methods: Water contact angle was measured by using G-1 type measuring device (Erma.Co). Compressive strength was measured by using a universal testing machine (Autograph AG-850, Shimadzu) at a crosshead speed of 1.0 mm/min. Water sorption in distilled water at 37 Celsius degree was measured up until 30 days. Results: Contact angle values of FCP composites were significantly enhanced with increasing amount of FCP (p<0.05). Compressive strengths of FCP composites were relatively lower than those without FCP. Water sorption of FCP composites with high fluorine content showed reduced values compared with control. Conclusions: This study demonstrated that the presence of the fluorine-cross-linked polymer would increase hydrophobicity and antibacterial effects of the new resin-based materials.
