Comparison of color stability of two resin composites in blood area

Color stability of nanohybrid and microhybrid composites after immersion in common coloring beverages at different times: a laboratory study

“…2 ) and incubated for 24 h at 37 °C for rehydration and polymerization completion [ 24 ]. It was expected that polishing helped in creating conditions that were closer to the clinical circumstances [ 20 ]. Polishing procedures were performed for 10 s for each step to avoid micro-crack formation [ 21 ].…”

“…Each glass slide was 1.5 mm thick and covered with a transparent nylon strip to form a smooth glossy surface and to avoid oxygen inhibition (preventing the formation of an unpolymerized airinhibited layer; Fig. 1) [18][19][20], and the two slides were pressed gently together by compression with a 500 g device for 20 s to allow the escape and removal of excess material [21].…”
