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 compare surface treatments (as-printed, optical polish, resin-coated, polished) of two 3D-printed occlusal device materials (KeySplint Soft and NightGuard Flex 2) cured with or without glycerin for surface roughness, translucency, and coffee staining. MATERIALS AND

methodsDiscs (2 mm thick) from two 3D-printed occlusal resins (KeySplint Soft and NightGuard Flex 2) were printed using a DLP 3D printer (SprintRay Pro 95), cleaned (ProWash S), and cured (ProCure 2) with or without glycerin. Some specimens were printed in an optical polish tank. Specimens were either as-printed, resin-coated, or polished. Reference milled (ProArt CAD Splint) and heat-cured (Excel Formula Heat Cure Denture Base Material) specimens were also prepared. Surface roughness was analyzed using a contact profilometer. Translucency was measured using a spectrophotometer. Staining was evaluated after 24 days in coffee at 37°C. Data were analyzed with ANOVA and Tukey post hoc tests.

resultsSurface treatments and glycerin curing showed significant differences (p < 0.01). Polishing and resin-coating produced the smoothest surfaces. Optical polish tanks improved smoothness. Polishing increased translucency. Glycerin curing reduced staining except in polished specimens. Milled materials stained less than 3D-printed materials.

conclusionsPolishing and resin-coating optimized roughness and translucency. Polishing or curing glycerin optimized stain resistance. CLINICAL SIGNIFICANCE: 3D-printed occlusal devices should have their external surfaces polished or resin-coated and receive a final cure in glycerin to prevent staining of their internal as-printed surface. Printing in a tank with an optical polish can help to improve the roughness and translucency of the internal surface of an occlusal device.
