Staining Susceptibility Of Microhybrid And Nanohybrid Composites On Exposure To Different Color Solutions

Abstract

Objectives: Composite discoloration is considered one of the most significant disadvantages of dental restorations. The purpose of our study was to assess the color susceptibility of two aesthetic composite filling materials, Microhybrid composite (ValuxTM Plus) and Nanohybrid composite (FiltekTM Z250 XT), to different solutions and compare the results among different measurement methods (Intraoral scanner, Easyshade Spectrophotometer, and Vita classic shade guide). Conclusions: Microhybrid composite had more color stability than nanohybrid composite, especially when immersed in tea and coffee. The spectrophotometer with Vita classical shade guide showed better interrater agreement than with the intraoral scanner.
