Evaluation of the radiopacity of single-shade composite restorative materials using a digital radiography system.
Article in Clinical oral investigations, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
objectivesRecently, single-shade universal composite resins have been introduced to the market to simplify restorative procedures. The inorganic structures of dental composites may influence several properties, including radiopacity. Radiopacity plays a crucial role in clinical dentistry as it enables the detection of recurrent caries, marginal defects, and restoration overhangs through radiographic examination. The aim of this investigation was to assess the mean gray value and compare the radiopacity of different single-shade composite resins using digital image analysis. MATERIALS AND
methodsSeven single-shade universal composite resins (Omnichroma, Charisma Topaz One, Vitra Aps Unique, Admira Fusion x-tra universal, X-tra Fill, Essentia Universal and ZenChroma) and one multi-shade universal composite resin (Optishade) were used. The enamel-dentin segment, a typical aluminum (Al) step-wedge (1-10 mm), and the samples were placed on a phosphor imaging plate. For each image, the MGV and the standard deviation of the grey values for three different regions were calculated and the mean of these three values was recorded.
resultsmmAI measurements of the study groups were found to be statistically significant different (p < 0.05). The differences were found between Charisma one and Voco xtrafil groups and between Enamel, Dentin and Zenchroma groups. Also, differences were observed between Dentin and Vittra aps unq groups. The radiopacity values of all materials tested were found to meet the requirements of ISO.
conclusionsIt is found that Glass particles containing composites have similar radiopacity as enamel due to their low atomic weight. Zirconium particles containing composites are more radiopaque than glass particles containing composites because of their higher atomic weight.
