![]() Since there are no sharp cutting edges and no ‘scraping’ sound, many patients find ultrasonic scaling is more comfortable than scaling with hand dental instruments.Ultrasonic scalers have replaceable, specially-designed tips that can penetrate difficult nooks and corners.Using an ultrasonic scaler, hygienists can remove calculus from pockets between teeth and gums at probing depths that are unreachable with hand tools (4mm or greater.).Other benefits to ultrasonic scaling include: Ultrasonic scaling is highly effective in removing subgingival/supragingival calculus from teeth without damaging roots or gum tissue. ![]() In any case, hygienists should read the manufacturer’s directions as to a tip’s proper usage. Thicker tips are generally suitable for use with higher power settings to remove heavier calculus deposits, whereas thin tips are used for light calculus or biofilm removal. The oscillating tip of an ultrasonic scaler is replaceable, with tips of various shapes and diameter available for different purposes. These shockwaves help to disrupt bacterial biofilm and fracture the calculus deposits as they are pounded by mechanical force. The vibration of the tip creates pressure waves in the water dispersed as coolant, causing the formation and implosion of atomized gas bubbles. Ultrasonic scalers remove plaque through a dual application of mechanical force and cavitation. The hygienist guides the tip from the coronal to the apical of a tooth, pulverizing calculus so it can be washed away by a coolant spray. Once activated, the tip of an ultrasonic scaler oscillates at incredible speeds up to 35,000 cycles per second. The vibration is driven by a generator converts electricity into ultrasonic waves through piezoelectricity or magnetostriction. Not only is ultrasonic scaling more convenient to the hygienist than scaling with hand instruments, it has numerous benefits to patients’ oral hygiene as well.Īn ultrasonic scaler is a power-driven scaling device that utilizes ultrasonic vibration to break up hardened calculus deposits on patients’ teeth. But owing to advancements in ultrasonic scaling, the process has become increasingly efficient and effective. Scaling used to be a dental hygienist’s daily grind.
