CONCLUSIONS Based on a limited number of studies , the use of ergonomic saddle seats and dental loupes leads to improved working postures .
The use of loupes appears to relieve shoulder , arm and h and pain .
However , their effect on neck pain is scarce .
None of the studies reported on the effect of the saddle seats on musculoskeletal pain .
OBJECTIVES Musculoskeletal disorders affect a high percentage of dentists , dental hygienists and therapists .
Static and awkward working postures are considered as major risk factors .
Proper seat selection and use of magnification loupes are promoted for their ergonomic benefits .
The aim of this review was to evaluate the existing empirical evidence on the effect of the above interventions on ( i ) correction of poor posture and ( ii ) reduction in musculoskeletal pain .
The effect of magnification loupes on the performance of preclinical dental students.
OBJECTIVE optical magnifying devices such as magnification loupes are increasingly used in clinical practice and educational setting s. However , scientific evidence to vali date their benefits is limited . This study assessed the effect of dental magnification loupes on psychomotor skill acquisition during a pre clinical operative dentistry course . METHOD AND MATERIAL S the performance of first-year dental students was assessed during an Advanced Simulation Course ( AS ) using virtual reality-based technology ( VRBT ) training . The test group consisted of 116 dental students using magnification loupes ( + MAG ) , while students not using them ( -MAG , n = 116 ) served as the control . The following parameters were evaluated : number of successfully passing preparation procedures per course rotation , amount of time per tooth preparation , number of times students needed computer assistance and evaluation , and amount of time spent in the computer assistance and evaluation mode per procedure . Data were collected on each student through VRBT during the preparation procedure and stored on a closed network server computer . Unpaired t tests were used to analyze mean differences between the groups . In addition , student acceptance of magnification loupes was measured and evaluated through survey interpretation . RESULTS + MAG students completed more preparations , worked faster per procedure , and used the computer-assisted evaluation less frequently and for shorter periods , therefore displaying greater overall performance . The survey revealed a high degree of student acceptance of using magnification . CONCLUSION dental magnification loupes significantly enhanced student performance during pre clinical dental education and were considered an effective adjunct by the students who used them
