Improving chairside ergonomic behavior in postgraduate dental students through a structured interprofessional education module: a quasi-experimental study.

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: Inadequate ergonomic methods in dentistry put practitioners under disproportionate biomechanical strain, which increases the risk of musculoskeletal problems over the course of a working career. Because they carry out intricate, drawn-out chairside operations without further assistance, clinical postgraduate dentistry students constitute a high-risk population. This study assessed whether postgraduate dentistry students' ergonomic knowledge, attitudes, and chairside behavior might be quantitatively improved by an organized interprofessional education (IPE) program. Methods: A quasi-experimental pre-post design was used. Prosthodontics, Periodontics, Oral Surgery, Conservative Dentistry, and Endodontics were the five clinical departments where all 36 postgraduate dental students were enrolled. Departments without direct patient-care duties were not included. The six-week course included chairside stretching exercises, environmental modification advice, interactive discussion, and didactic instruction. At weeks two and six, unannounced photos were used to grade ergonomic behavior using the validated MEND (Meenakshi's Ergonomic Needs for Dentistry) assessment; pre- and post-test questionnaires were used to measure knowledge. Results: Each of the 36 participants finished both assessments. MEND scores improved statistically significantly in all four departments ( Conclusion: Clinical postgraduate dentistry students' chairside ergonomic behavior and understanding significantly and consistently improved because of an organized, interprofessionally presented ergonomic module. It is necessary to incorporate such a program from the very beginning of clinical training.
