Influence of different curing modes on the bonding effectiveness of self-adhesive resin luting cements in combination with universal adhesives.

Objectives: This study aimed to investigate the immediate dentin bond performance and bond durability of self-adhesive resin luting cements (RLCs) in combination with universal adhesives in different curing modes.

Methods: Two self-adhesive RLCs were used with universal adhesives as primers. They were also used alone as self-adhesive RLCs.

Evaluation of structural coloration of experimental flowable resin composites.

Objective: To examine the effect of filler contentTo examine the effect of filler content on structural coloration of experimental flowable resin composites.

Overview: Experimental composites containing spherical fillers and different filler contents (30, 40, 50, 60 and 70 wt%), a structural colored resin composite (Omnichroma), and a nanohybrid flowable resin composite (Gracefil LoFlo) were used. The optical characteristics of the specimens were measured on standard black and white backgrounds using a spectrophotometer under CIE D65 illuminant and the L*a*b* values were determined.
