![]() ![]() To test for mercury emissions, samples of constant volume of wastewater from high-speed drills were collected before and during amalgam restoration removal. To test for mercury levels, patients were tested before and after amalgam restoration removal. ![]() more The aim of this study was to evaluate mercury levels in wastewater and in patients during the removal of dental amalgam restorations. The aim of this study was to evaluate mercury levels in wastewater and in patients during the rem. The results of this study demonstrated that the presence of a fiber post significantly raised flexural strength values and the glass fiber post significantly increased the modulus of elast. Group 3 obtained a higher mean modulus of elasticity than Groups 1 and 2, which were similar. Both fiber posts were similar in strength and both were stronger than the control. The results were statistically analyzed by ANOVA and Tukey's test (P = 0.05). The samples were immersed in water at 37 degrees C until the three-point loading test was performed at a speed of 1.0 mm/minute. Each group contained 10 specimens: Group 1, resin without post Group 2, resin with carbon fiber post Group 3, resin with glass fiber post. Thirty bar-shaped specimens measuring 25 x 2.0 x 2.0 mm were made, containing posts that were 1.3 mm in diameter and 20 mm long. ![]() more The aim of this study was to evaluate the effect of prefabricated fiber posts on the flexural strength and modulus of elasticity of a composite resin.
