Overview

Randomized trial demonstrates that preheating resin composite reduces film thickness without compromising bond strength in extracted molars, highlighting its potential and limits as a luting agent.

Key Points

  • To evaluate the microtensile bond strength and film thickness of preheated resin composite when utilized as a luting agent for indirect adhesive restorations.
  • Fifteen extracted molars were randomly assigned to three groups (N = 15): dual-cure resin cement (control), room-temperature resin composite, and preheated resin composite.
  • Specimens underwent microtensile bond strength testing (n = 75) and cement layer film thickness evaluation under a stereomicroscope (n = 72), analyzed using one-way ANOVA, Tukey, Kruskal-Wallis, and Dunn tests.
  • Dual-cure resin cement achieved higher microtensile bond strength than room-temperature resin composite, while preheating composite produced bond strength values that aligned with the dual-cure cement control (exact numerical values not reported).
  • Film thickness was lowest in the dual-cure resin cement group, followed by preheated resin composite, with the highest thickness recorded in room-temperature resin composite.
  • Although preheating significantly reduced composite layer thickness, the resulting film thickness remained above the clinically acceptable threshold for indirect restoration luting.
