Hand anthropometry, grip strength, and manual dexterity: A correlational study among dental students.
Article in SAGE open medicine, 2026. 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
Objective: Hand anthropometry, grip strength, and manual dexterity are fundamental to the safe and the effective performance of dental procedures. While these factors are individually important, their interrelationships in dental students remain insufficiently explored. This study aimed to examine the correlation of hand anthropometric dimensions with grip strength, and manual dexterity among dental students, and to evaluate their potential implications for dental education and ergonomic instrument design. Methods: This cross-sectional study included 100 dental students. Thirty hand anthropometric dimensions were measured using a digital caliper and measuring tape. Power grip strength was assessed using a Jamar hydraulic dynamometer, and fine grip strength (tip pinch and key pinch) using a hydraulic pinch gauge. Manual dexterity was evaluated with the Roeder Hand Aptitude Test. Descriptive statistics, independent Results: All hand anthropometric dimensions showed significant positive correlations with power and fine grip strength, with the strongest associations observed for palm width and hand length. Male students demonstrated significantly higher grip strength than female students across all grip types ( Conclusion: Hand anthropometric dimensions are strong predictors of grip strength but have limited influence on manual dexterity. These findings suggest that while grip strength is largely determined by physical characteristics, manual dexterity is more dependent on motor coordination and practice. The results support the importance of ergonomics-based dental education and the consideration of hand-size variability in the design of dental instruments.
