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 .
Work-related musculoskeletal disorders among Brazilian dental students.
The aim of this analytical cross-sectional study was to evaluate the presence of work-related musculoskeletal disorders ( WMSD ) among dental students in two Brazilian dental schools . The sample included 227 r and omized subjects from fifth to ninth semesters who were developing clinical activities . Each student signed an informed consent form . A self-reporting question naire was used to obtain data on the practice of physical exercise , the presence of pain during or soon after treating patients , and the adoption of preventive measures related to clinical activities . Results were analyzed using the Statistical Package for Social Sciences 13.0 . The chi(2 ) test was used to identify associations between variables . The presence of pain during or after clinical work was reported by 173 participants ( 76.2 percent ) . Statistically significant differences were found between gender and the occurrence of pain . Pain was present during clinical activities ( p=0.006 ) and imposed limitations on the work routine ( p=0.011 ) . Among those who practice d physical exercise , eighty-eight ( 74.6 percent ) reported pain . The high percentage of pain reported by dental students suggests the value of review ing work conditions in dental practice s in order to minimize the exposure of all workers to WMSD
