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

objectivesTo evaluate the effects of hydrothermal ageing on biofilm adhesion and surface properties of denture base resins fabricated via different techniques. MATERIALS AND

methodsDenture base resin samples were produced using the following manufacturing techniques: conventional cold polymerization (CP), heat polymerization (HP), CAD-CAM milling (CADm) and CAD-CAM printing (3D). The samples were tested before and after hydrothermal ageing (5000 cycles, 5 °C/55°C). The surface roughness was measured using atomic force microscopy (AFM), and the hydrophobicity was observed by measuring the water contact angle (WCA). Monomicrobial biofilm of Staphylococcus aureus and Candida albicans were formed and quantified before and after ageing using colony-forming units (CFUs/ml) and the MTT test. Statistical differences were evaluated using a two-way analysis of variance (ANOVA).

resultsTwo-way ANOVA showed that ageing significantly influenced the roughness (p = 0.002). The highest roughness values before and after ageing were measured for 3D resin samples. The WCA values of 3D resin samples changed after ageing (p = 0.018). Amount and metabolic activity of monomicrobial biofilms were increased during ageing on all four tested denture base resins.

conclusionsAgeing influenced the roughness and microbial adhesion on all tested denture base materials, regardless of the manufacturing method. CLINICAL RELEVANCE: Finding support replacing dentures every five years due to increased biofilm adhesion post ageing.
