The objective of the study is to evaluate the effects of repeated bracket bonding on the color changes of tooth enamel after in vitro coloration. ⋯ Repeated bracket bonding does not have a negative influence on the enamel color change after in vitro coloration when compared with intact enamel surface and single bonding.

The aim of the present investigation was to evaluate the effect of autoclave polymerization method on the mechanical and dynamic mechanical properties of different polymethylmethacrylate denture base materials. ⋯ Autoclave polymerization provided higher polymerization temperatures compared with the conventional heat polymerization. Autoclave-polymerized acrylic resin specimens showed higher tensile strength values; however, this was not the case for the impact test results. Flexural strength of specimens was improved with autoclave polymerization. Glass transition temperature was increased with autoclave polymerization.
