Color stability of a resin nanoceramic after surface treatments, adhesive cementation, and thermal aging.

Statement Of Problem: Whether color changes in resin nanoceramic (RNC) restorations can occur because of material and adhesive interface degradation is unclear.

Purpose: The purpose of this in vitro study was to evaluate the color of RNCs submitted to surface treatments, cementation, and aging.

Material And Methods: RNC specimens (N=120) were produced with a thickness of 0.
