Influence of electronic cigarette vapour on the in vitro chromatic stability of different nanohybrid composite resins

Chromatic stability of composites after exposure to e-cigarette vapours varied depending on the material brand, with FORMA™ resin showing clinically unacceptable chromatic differences, whereas Filtek™ Z350 XT and Palfique LX5 resins showed clinically acceptable chromatic differences, with the latter showing greater resistance to colour change and therefore greater chromatic stability. These findings serve as a guide in decision-making relative to the selection of restorative materials indicated for patients with vaping habits.
