Abstract

Background: Acrylic resin is a dental material that is often used because it is easy to apply and has good aesthetics. One type of acrylic resin used for denture base materials in dentistry is Heat Cured Acrylic Resin (HCAR). HCAR as base for dentures also has disadvantages including low tensile strength. Therefore, fiber can be added to heat cured acrylic resin as a reinforcing material (FRAR). This study aims to determine the effect of the addition of non-dental glass fiber on the tensile strength of HCAR.Method: This is a true experimental research using posttest only control group design. Divided into two groups, the first one is HCAR without the addition of non-dental glass fiber, the second group is HCAR with the addition of non-dental glass fiber. The data are tested using the Independent T-Test parametric test.Result: The average tensile strength of the HCAR without Non Dental Glass Fiber was 46.5169 MPa, while the average tensile strength of HCAR with the addition of Non Dental Glass Fiber was 60.3269 MPa. The independent test results show p value of = 0.000Conclusion: It was found that heat cured acrylic resin with the addition of non-dental glass fiber has a higher tensile strength than heat cured acrylic resin without the addition of non-dental glass fiber which could be used as an alternative choice in applications in dentistry.

Abstract

Background: The descrease of the tooth surface hardness can be affected by the microorganisms activity that ultimately cause the damage of the tooth surface hardness. The process of remineralization is needed to restore the lost minerals. A fsh that contain of calcium, phosphorus and fluoride can help the process of remineralization. The purpose of this research is to determine the difference of fsh consumption pattern toward the enamel hardness of deciduous teeth at Teluk Awur Village and Jlegong Village of Jepara Regency.Methods: This research methode was experimental type laboratoris with research design of post only control group and consist of two groups that were coastal area and non coastal area group. The sample used was the lower anterior decicuous teeth that revocation of 14 units. The tooth hardness was measured with the Micro Vickers Hardness Tester, followed by data analysis with Independent T-test.Result: The results showed that the mean of surface hardness of deciduousteeth in Teluk Awur Village was 1009.91 VHN while in Jlegong Village was 691.31 VHN. The Independent T-test showed the signifcance result was 0.012 (P <0,05) and interpret that there were differentiation in fsh consumption patterns between the groups toward the enamel hardness of deciduous teeth.Conclusion: The conclusion of this research showed that there is differentiation of enamel hardness of deciduous teeth at the age of 5 - 7 years at Teluk Awur Village and Jlegong Village which have got treatment to consume fsh.

Abstract

Background: Fiber reinforced composite is a combination of composite resin and fiber. Fiber in FRC serves as a reinforcement to be resistant to fractures. One of the fibers used in FRC is dental glass fiber because it can increase mechanical strength. Dental glass fiber is very limited and expensive while glass fiber which available in the market is non dental glass. This material has mechanical properties almost same as dental e-glass fiber used in dentistry, so it can be used as an alternative material FRC. The aim of this study was to identify the effect of flexural strength of non dental glass fiber to prepolymerized fiber reinforced composites.Method: This study used true experimental design with 16 samples. The samples were divided into two groups according to prepolymerized composite resin groups without fiber and prepolymerized composite resins with the addition of non dental glass fiber. Data analysis in this study used the normality test with the Sapiro-Wilk test, levene test and independent t-test. Result: The results were statistically analyzed, the average flexural strength of prepolymerized composite resin without fiber is 36.60 MPa and prepolymerized composite resin with the addition of non dental glass fiber which is 54.26 MPa. Based on the normality test and the levene test values (p> 0.05) and independent t-test values (p <0.05) were obtained.Conclusion: The conclusion obtained that there is an effect of the addition of non dental glass fiber to the flexural strength of prepolymerized fiber reinforced composite.
