Foundational Skills for Periodontal Instrumentation
-Periodontal instrumentation is a complex psychomotor skill -Requires the proper position, instrument grasp, mirror use, finger rests, and stroke production-For successful instrumentation, must have mastery of individual skill components…these skills are mastered one-by-one
