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

backgroundResin-based pit and fissure sealants, used to prevent dental caries, can experience abrasive wear. This study aimed to assess the abrasive wear of experimental pit and fissure sealants (DIF) compared with the other commercial pit and fissure sealants by measuring surface roughness, volume loss, and ultrastructure after chewing simulation at different time points.

methodsSpecimens were divided into five groups (n = 10): Clinpro™(CP), Teethmate™ White (TW), Teethmate™ Natural (TN), experimental sealant (DIF), and Filtek™ Supreme Flowable Restorative (FC). They underwent chewing simulation with 120,000, 240,000, and 360,000 strokes. Surface roughness and volume loss were measured with a profilometer, and ultrastructures were assessed using scanning electron microscope (SEM).

resultsAll specimens showed a significant increase in surface roughness after chewing simulation. FC had the highest roughness (p < 0.001) whereas DIF did not differ from other groups (p > 0.05). All materials experienced significant volume loss. Sealant types and chewing cycles affected volume loss, with CP showing the highest and TW the lowest (p < 0.001). SEM analysis revealed worn areas with circular or oval shapes, with CP and TN having larger diameters and TW the smallest.

conclusionsDIF showed acceptable surface roughness and wear resistance compared to other commercial products after chewing simulation.
