The Effects Of Sitting And Standing Hygiene On Posture In Dental Hygiene Students, Taylor Shay Kace

Dental Hygiene Theses & Dissertations

Problem: The purpose of this pilot study was to assess biomechanical and postural impacts of sitting and standing independently during dental hygiene practice. Methods: A convenience sample of thirty-four second-year dental hygiene students with no history of musculoskeletal disorders were enrolled in this study. Participants were randomly assigned to instrument one quadrant of the mouth on buccal or lingual surfaces while seated or standing during two independent research sessions. Two images per session, for a total of four images per participant, were taken to assess biomechanical demands of each posture using the Rapid Upper Limb Assessment (RULA) tool. The images …

Electromyographical Assessments Of Recommended Neck And Trunk Positions For Dental Hygienists, Margaret F. Lemaster, Kyle J. Kelleran, Maryam Moeini, Daniel M. Russell

Rehabilitation Sciences Faculty Publications

Purpose: Dental professionals are recommended to limit neck and trunk flexion to within 20° of a neutral (0°) body posture, however empirical support for the recommendations is lacking. The purpose of this study was to determine whether there are differences in muscle workload between a range of neck and trunk postures in a population of dental hygiene students.

Methods: Fifteen first semester senior dental hygiene students with no history of neck and trunk injury volunteered to participate. Surface electromyography was used to record muscle activity from two neck extensors muscles, cervical erector spinae (CES) and upper trapezius (UT), and two …

The Effects Of The Traditional Scaling Technique Versus A Modified Scaling Technique On Muscle Activity And Pinch Force Generation: A Pilot Study, Jessica R. Suedbeck, Cortney Armitano-Lago

Dental Hygiene Faculty Publications

Purpose: Dental hygienists perform precision instrumentation tasks repetitively throughout the workday, placing them at increased risk for developing a musculoskeletal disorder. The purpose of this pilot study was to determine differences in muscle activity and pinch force generation between the traditional scaling technique and a modified scaling technique.

Methods: A convenience sample of dental hygienists (n=12) acted as their own controls in this counterbalance-designed pilot study. Muscle activity and pinch forces were assessed while participants performed traditional and modified scaling techniques with designated instruments on artificial calculus applied to the lower left quadrant of a typodont, for a period of …
