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

Objective: To evaluate the effect of zirconia surface topography on epithelial attachment and peri-restorative soft tissue healing following diode laser-assisted crown lengthening. Materials and methods: A controlled split-mouth experimental study was conducted in 12 Beagle dogs. Bilateral mandibular sites received CAD/CAM zirconia restorations with either glazed or micro-roughened cervical surfaces. Crown lengthening was performed using a diode laser, followed by full thickness mucoperiosteal flap elevation and osteoplasty. Clinical parameters and histomorphometric analysis were assessed at 2 and 4 weeks postoperatively. Results: Micro-roughened zirconia surfaces demonstrated significantly enhanced epithelial attachment, improved collagen organization, and superior soft-tissue adaptation compared with glazed surfaces ( Conclusion: Zirconia surface topography significantly influences peri-restorative soft tissue healing. Micro-roughened surfaces promote superior epithelial attachment and tissue integration following laser-assisted crown lengthening.
