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

Marginal adaptation is a crucial determinant of dental restoration success, directly influencing longevity and clinical outcomes. This study investigated the impact of fitting procedures on the marginal adaptation of CAD/CAM-fabricated all-ceramic crowns. Eight extracted human molars were prepared for crown fabrication using standardized techniques. An impression was carried out for each specimen and poured with type IV dental stone, followed by the CAD/CAM-based design and fabrication of the crowns. Marginal gaps were measured at eight designated points on each specimen using a Hirox Digital Microscope, both before and after fitting procedures. Findings revealed a significant reduction in marginal gaps post-adjustment, with values ranging from 270.55 μm to 9.64 μm before the fitting procedure and 124.4 μm to 3.81 μm after fitting procedures. These results emphasize the efficacy and importance of fitting procedures in enhancing marginal fit, reducing gaps to clinically acceptable levels, and minimizing potential complications such as microleakage and secondary caries. The study highlights the critical role of fitting procedures in optimizing the marginal fit of CAD/CAM crowns, thereby improving their clinical performance and longevity.
