Objective The objective of this study was to compare the effects of 10 commercially available
instrument handle designs' mass and diameter on forearm muscle activity during a …

Purpose: The purpose of this study was to determine the effects of 4 different commercially
available instrument handle designs (A. 16 grams and 12.7 mm diameter, B. 23 grams and …

Background In comparison with people in other occupations, dentists and dental hygienists
are at increased risk of developing work-related musculoskeletal disorders, including carpal …

Purpose. This study was conducted to determine the effects of 5 different finger rest
positions: opposite arch, standard intraoral, basic extraoral, cross arch, and finger on finger …

Purpose: Dental hygienists perform precision instrumentation tasks repetitively throughout
the workday, placing them at increased risk for developing a musculoskeletal disorder. The …

Purpose. Ergonomic studies suggest that the commonly used pinch grasp, held in a static
position, is a contributing factor for dental Hygienists' development of work-related …

Purpose: The purpose of this study was to determine strength of muscles involved with
instrumentation (scaling) by dental hygienists and the additive effects of cellular (mobile) …

Background Periodontal scaling might cause musculoskeletal disorders, and scaling
instruments might not only have different effectiveness and efficiency but also differ in their …

Background: To compare fatigue, comfort, and muscle work associated with the use of two
periodontal curettes during scaling: one with a novel adaptive design, the other with a …

The purpose of this study was to evaluate muscle activation and fatigue in the operator
during tooth preparation and intraoral scanning by simulating these tasks in two types of …
