This webinar will discuss power tools and hand instruments (scalers and curettes) needed to perform a professional dental cleaning (scaling and polishing). Closed periodontal therapy (root planing and gingival curettage) and perioceutic treatment (local administration of medications) will be reviewed. Instrument sharpening will be briefly explained. The didactic lecture will last 1 hour, but the webinar is designed so that there is extra time for interactive participation and answering your questions.
