Evaluation of ergonomic work postures among dental students during restorative procedures using an artificial intelligence-based assessment model.

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
Background: Dental professionals are frequently exposed to work-related musculoskeletal disorders (WMSDs), with ergonomic risks often emerging during undergraduate dental training. While most existing studies rely on self-reported questionnaires, objective evaluations of work postures remain limited. This study aimed to evaluate work postures adopted by dental students while performing restorative procedures in simulation laboratories using an AI-based assessment model. Methods: A cross-sectional analytical study was conducted among dental students. Participants were recruited through a non-probability purposive sampling method. They were photographed while performing dental procedures in a simulation laboratory. The images were analyzed using a previously validated AI-based Assessment Model [SBK-DentErgo]. Results: A total of 75 students were included in the final analysis. Regarding overall postural aspects, it is noteworthy that none of the students demonstrated acceptable posture. The mean score for the overall posture analysis was 14.2 (±1.6). Among the postural aspects, the hip was highly compromised in 55 (73.3%), followed by upper arm in 52 (64.3%), wrist 48 (64%), neck (side to side) 36 (58.7%), elbows 38 (50.7%), neck (front) 36 (48%). Fisher's Exact test showed D3 students significantly had acceptable hip angulation posture, 10 (52.6%) acceptable, compared to D2 students, among whom 16 (88.9%) exhibited compromised hip angulation ( Conclusions: Dental students adopt improper postures during dental procedures, indicating an early risk of developing ergonomic problems during their training. This AI-model is effective for objective evaluation of ergonomic work postures and can serve as supplementary educational tool for detecting postural deviations in educational settings.
