The Effects Of Universal And Rotating Ultrasonic Inserts On Wrist Movement, Scaling Time Efficiency, And Cumulative Trauma Risk In Dental Hygienists, Christine Colavita Hawn
Dental Hygiene Theses & Dissertations
The purpose of this study was to determine if differences existed in range of wrist movements and scaling time efficiency in dental hygienists that use a rotating ultrasonic insert as compared to those who use a standard universal insert. A convenience sample of 30 consenting experienced dental hygienists from the Norfolk area who met inclusion criteria was invited to be subjects. Using a crossover research design, each experimental subject used the rotating ultrasonic scaling insert to remove 2 cc artificial calculus from a typodont in a controlled, simulated clinical situation for up to 15 minutes. While scaling, each subject wore …
Effects Of Ultrasonic Scaling And Hand-Activated Scaling On Tactile Sensitivity In Dental Hygiene Students, Danielle Leigh Ryan
Effects Of Ultrasonic Scaling And Hand-Activated Scaling On Tactile Sensitivity In Dental Hygiene Students, Danielle Leigh Ryan
Dental Hygiene Theses & Dissertations
This study was conducted in order to determine if tactile sensitivity varies in dental hygiene students who use the ultrasonic scaler as compared to those who scale with handactivated instruments. A convenience sample of 40 consenting, first year dental hygiene students were randomly assigned to one of two groups. The 40 students had not yet used the ultrasonic scaler nor had any history of injuries or disabilities to the dominant arm, wrist or hand. After establishing a baseline tactile sensitivity score with the Vibratory Sensory Analyzer (VSA), experimental group subjects used the ultrasonic scaler to remove 4cc's of artificial calculus …
