OBJECTIVES: Ultrasonic scaling technology has evolved dramatically providing greater clinical utility subgingivally including instrumentation of light deposits and biofilm disruption. It is unknown whether dental hygiene curriculum has kept pace with the progression and reflects current applications. The first part of this two-part study aimed to determine new dental hygiene graduates' use and perceptions of preparedness in ultrasonic instrumentation. Part 2 investigates ultrasonic curriculum from the programme director perspective and will be reported on in a subsequent paper. METHOD: Part 1 of the study surveys recently graduated Canadian dental hygienists about their use and perceptions of preparedness with ultrasonic instruments through an electronic questionnaire developed for this study. RESULTS: Participants reported using ultrasonics about half of their instrumentation time predominantly with magnetostrictive technology. Use focussed on heavier deposits with straight, slim inserts. Subjects were generally satisfied with ultrasonic education and felt reasonably well prepared in using ultrasonics. Higher levels of perceived preparedness were most associated with graduates from the 3-year diploma programme, whereas graduates from 18-month programmes were associated with greater levels of confidence in using ultrasonics. Confidence with ultrasonics did not have an effect on subsequent use - mostly all participants increased use once in practice. An earlier introduction and more practice time in school were both associated with increased feelings of preparation and confidence. CONCLUSIONS: New dental hygiene graduates perceive greater preparedness, confidence and use of ultrasonic instrumentation within a more traditional paradigm. In addition, the results indicate a potential incorrect and/or inappropriate application of current technology.
