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

backgroundThe color stability and surface roughness of resin composites are the primary factors influencing the qualities of restorative materials. This study aimed to assess the color stability and surface roughness of a smart monochromatic resin composite submerged in various staining solutions. MATERIALS AND

methodsNinety-nine disc samples of composite resins (8 mm in diameter and 2 mm in thickness) were prepared and divided into three groups (n = 33): Group A, Omnichroma (Tokuyama Dental, Tokyo, Japan); Group B, Neo Spectra ST HV (Dentsply, Konstanz, Germany); and Group C, Filtek Z350XT (3MESPE) composite resins. The samples were assessed for color stability (M) via a Vita Easyshade spectrophotometer and surface roughness (Ra) with a profilometer before and after thermocycling for a total of 1000 cycles at 5°/55°C with a 15-second dwell time. Each group was subdivided into three subgroups according to immersion solution (n = 11): Subgroup I was submerged in distilled water as a control, Subgroup II was submerged in tea, and Subgroup III was submerged in coffee. Color assessment was performed after immersion periods of T1: 7 days, T2: 15 days, and T3: 30 days with a Vita Easyshade spectrophotometer. A color change (∆E00) was obtained via the CIEDE2000 color difference formula. Surface roughness was assessed with a profilometer after 30 days of submersion in the staining solutions.

resultsAmong all the samples in the study groups, Omnichroma had the lowest color change value for all the immersion solutions at different time intervals (p < 0.001). The surface roughness of Omnichroma significantly differed after thermocycling (P = 0.075). However, Omnichroma had the least surface roughness compared with Neo Spectra ST HV (P = 0.026) and Filtek Z350XT (P = 0.024).

conclusionThe color change and surface roughness of the supra-nanofilled (Omnichroma) resin-based composite were inferior to those of the nanohybrid (Neo Spectra) and nanofilled (Filtek Z350XT) composites.
