Effect of microgravity on the feasibility and accuracy of dental procedures.
Article in NPJ microgravity, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Developing effective countermeasures against oral health risks is essential for long-duration space missions. This study evaluated the feasibility of performing restorative dentistry procedures in a microgravity environment. A parabolic flight campaign aboard the Airbus A310 was conducted through the ESA Academy Experiments programme. The campaign included 90 parabolas over 3 days, each providing ~22 s of microgravity. Two senior dentistry students performed 72 caries preparations and 36 composite restorations on artificial teeth in three environments: ground, microgravity, and steady flight. Accuracy was evaluated using computer-aided 2D image analysis for preparation errors and 3D scanning for restoration errors. Statistical analysis using two-way ANOVA revealed no significant impact of environmental conditions on preparation (p = 0.623) or restoration (p = 0.139) accuracy, although operator differences were observed. These findings indicate that microgravity does not significantly impair the accuracy of restorative dentistry procedures, highlighting the potential to expand dental treatment in space.
