Background and Aim: Color match between prosthetic restorations and natural teeth is challenging in dentistry. The aim of the current study was to assess the effect of accelerated aging on color stability of two silica-based ceramics with leucite and lithium disilicate crystalline phases after glazing and polishing surface treatments. Materials and Methods: In this experimental study, 30 disc-...
Objective: Propolis is a resinous material produced by honeybees that has recently gained fame as an antimicrobial agent. This study sought to assess the effects of propolis as an intra-canal medicament on tooth discoloration. The effect of its application technique on the degree of discoloration was investigated as well. Methods: This experimental study was conducted on 40 intact anterior huma...
Abstract Background Esthetic dental restorations have gained increasing popularity. The surface of should be smooth enough to achieve maximum esthetics and prevent the adhesion microorganisms food particles. This study aimed assess roughness color change composite specimens following airflow usage. Methods In this in vitro, experimental study, 30 Tokuyama discs were fabricated randomly divided ...
Tone mapping algorithms offer sophisticated methods for mapping a real-world luminance range to the luminance range of the output medium but they often cause changes in color appearance. In this work we conduct a series of subjective appearance matching experiments to measure the change in image colorfulness after contrast compression and enhancement. The results indicate that the relation betw...
