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

objectiveThiourethanes (TU) improve mechanical properties and depth of cure in dental materials. This study investigated whether these benefits are maintained under light attenuation conditions, when TUs are combined with different photoinitiators, and used in cements cured under different ceramic thicknesses.

methodsBisGMA/UDMA/TEGDMA (50/30/20 wt%) were combined with 0 or 20 wt% TU. Camphorquinone/amine (CQ/EDMAB), BAPO, or Ivocerin were used as photoinitiators. Polymerization kinetics and light transmission were monitored by near-IR spectroscopy during photoactivation (320-500 nm, 1580 mW/cm², 300 s, n = 3) through 0, 0.5, and 1.5 mm ceramic. Irradiance and photoinitiator consumption were evaluated by UV-Vis. Data were analyzed by three-way ANOVA/Tukey's test (α=0.05).

resultsConversion increased with TU under most conditions (p < 0.001), but decreased as a function of ceramic thickness (p < 0.001), due to reduced irradiance. TU only reduced Rp

conclusionTU improved conversion under all conditions, and led to at least partial recovery of the loss in conversion observed under light attenuation conditions under different ceramic thickness, compared with non-TU controls. That recovery was greater when TU was combined with alpha-cleavage type initiators. SIGNIFICANCE: Combining TU with alternative photoinitiators improves curing under light attenuation.
