A distinct body of literature supports the association between clinical postures of the dental practitioner and workrelated musculoskeletal disorders (WRMD). Several aids or devices have been tested to improve clinical posture in the interest of decreasing WRMD. The use of magnification lenses while performing dental procedures may increase the quality of work and decrease the likelihood of musculoskeletal problems. To date, only anecdotal and personal opinions had existed regarding the benefits of using magnification lenses, and no empirical evidence had authenticated the contention that use of magnification lenses exerts a positive change in operator posture. The objective of this study was to assess the effect magnification lenses had on the posture of dental hygiene students. Using a randomized crossover design, researchers videotaped nineteen senior dental hygiene students performing an intra-oral procedure with and without the use of magnification lenses. The tapes were then evaluated by a panel of five dental hygiene educators calibrated in the use of Branson's Posture Assessment Instrument (PAI). Results of a paired t-test indicate that the posture of the students while wearing magnification lenses was more acceptable (p=.019) than when wearing traditional safety glasses. Results of this study indicate a quantifiable change in acceptability of posture for clinicians wearing magnification lenses and suggest that the use of such lenses in dental education may be warranted.

“…The correlation of increased use of surgical magnification with decreased risks for experiencing lower back pain should be considered in the context that most of the users of surgical magnification in the study were VCC and UBC graduates with surgical telescopes that allowed for appropriate declination angles to match their optimal working postures. Some systems in use by clinicians today have limited ability to produce optimal declination angles (29, 30), and the reductions of MSSs for such users may not be the same as those generated in the British Columbia study. Surgical magnification without balanced positioning may not have the same effect.…”

“…There is an important caveat associated with the use of surgical magnification. While it appears that appropriately selected and adjusted magnification can help to support balanced posture (29), poorly selected or adjusted systems can actually promote positions that place clinicians at increased risk for problems. In our 1999 study (9, 10), the following patterns were associated with statistically significant increased risk of MSSs.…”

The potential for improving the occupational health of dental clinicians has expanded as increasingly sophisticated equipment enters the marketplace, yet there has been little improvement to the ergonomics with which dental hygienists operate. The use of surgical magnification has great potential to increase the quality of dental hygiene clinical care and to support the musculoskeletal health of dental hygienists. Although the research evidence to support a relationship between the use of surgical magnification and increased quality of dental hygiene care is extrapolated from parallel studies in dentistry, specific dental hygiene studies suggest that the integration of surgical magnification would be helpful in reducing the incidence of musculoskeletal symptoms experienced by dental hygienists. This is not to suggest that the integration of surgical magnification is a panacea for the musculoskeletal problems experienced by dental hygienists. In fact, improperly selected or adjusted surgical magnification systems can promote positions that place clinicians at increased risk for such problems. Clinicians must first determine the optimal working position that supports their musculoskeletal health and then select magnification systems that will support that position. The working distance, depth of field and optical declination angle of the chosen system must correspond to the musculoskeletal needs of the clinician.

“…The lighting may positively affect the ergonomics of the musculoskeletal system if suitably chosen and correctly adjusted. Conversely, a well-chosen but poorly adjusted system can contribute to the achievement or even the creation of unacceptable working movement (Rucker et al, 2009).…”

Aims and objectives. The aim of this study was to investigate the incidence of changes in the axial organ among dentists and dental hygienists as well as to compare the monitored parameters with a group of dental hygiene students.Background. The work of dentists or dental hygienists requires prolonged standing in non-ergonomic positions. This has a negative impact on their health. Current prevention programs seem to be ineffective. This paper deals with the biomechanical analysis and assessment of the health risk factors of dentists and dental hygienists.Methods. In order to evaluate possible risks, postural parameters were detected among 54 dentists and dental hygienists and 75 dental hygiene students by means of the SpinalMouse®. Changes in the basic shape of the spine position in the sagittal and frontal plane and mobility in the sagittal plane were monitored.Results. The results show an increased incidence of changes in axial organ among dentists and dental hygienists, which indicates a decreased quality of body control in young persons.Relevance for clinical practice. The study suggests that changes in the axial organ represent a signifi cant burden for the dental profession.
