Overview

Randomized trial compares color stability of three resins in artificial saliva, suggesting material choice affects aesthetics.

Key Points

  • This research aims to compare the color stability of three different photopolymerizable resins after immersion in artificial saliva.
  • Thirty-six disc specimens were printed and divided into control and immersion time groups (24 h and 72 h).
  • Color parameters were measured using CIELAB coordinates, and ΔE values were calculated with the CIE76 formula.
  • Statistical analysis done using the Kruskal–Wallis test to evaluate differences among resins.
  • Material was the primary factor impacting color stability (η2p = 0.774–0.964, all p < 0.001).
  • At 72 h, mean ΔE for Anycubic was 0.66, VOCO was 3.79, and GC was 3.58.
  • 75% of GC Temp Print specimens exceeded the clinical acceptability threshold (ΔE > 3.7).
