Abstract: (37 Views)
Background: The dental profession requires high levels of precision and fine motor control. Hand anthropometric dimensions, grip strength, and manual dexterity play critical roles in ergonomic tool design and performance. This study aimed to investigate gender differences in hand anthropometry, grip strength, and manual dexterity among dental students.
Methods: A cross-sectional descriptive-analytical study was conducted on 100 dental students (51 females and 49 males) at Urmia University of Medical Sciences. Hand dimensions were measured using a digital caliper, grip strength using a Jamar dynamometer, pinch strength using a SAEHAN pinch gauge, and manual dexterity using the Roeder test. Independent t-test was applied for gender comparisons.
Results: Male students had significantly larger hand dimensions and higher grip strength than females (p<0.001). However, there was no significant gender difference in manual dexterity (p>0.05).
Conclusion: Notable gender differences were found in hand anthropometry and grip strength but not in dexterity. Ergonomic design of dental instruments should consider these differences to reduce musculoskeletal strain and improve precision.
