1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Preheated restorative resin-based composites (RBCs) have been suggested as alternative luting agents for ceramic restorations; however, their polymerization and long-term degradation behavior require further clarification. This study compared a preheated RBC with conventional light-cured and dual-cured adhesive resin cements regarding degree of conversion (DC%), monomer elution, water sorption (WSo), and solubility (Sol). Standardized lithium disilicate overlays were luted to ceramic abutments using preheated Estelite Σ Quick (EQ_55°C), Variolink Esthetic LC (VE_LC), or Variolink Esthetic DC (VE_DC). DC% was assessed by micro-Raman spectroscopy, monomer elution using high-performance liquid chromatography at 3, 10, and 17 days, and WSo/Sol per ISO 4049 at 30, 60, and 90 days. VE_DC showed the highest DC% (72.1%), while EQ_55°C presented the lowest (59.9%). Monomer elution was significantly higher for VE_LC and VE_DC compared to EQ_55°C and decreased over time for all groups. WSo peaked at day 60 but remained significantly lower for EQ_55°C. Sol followed the pattern VE_DC > VE_LC > EQ_55°C, decreasing progressively with time. These results indicate that the preheated RBC demonstrated reduced monomer release and lower hydrolytic degradation, supporting its potential use as a stable luting alternative for indirect ceramic restorations.
