The ultrasonic scaler was first used in dentistry treatment way back in the 1950s. This days technology has advanced by far better mature and well-tested equipment. This represents the number of times the tip comes into contact with the tooth. The sonic scaler is usually air-driven, and its tip moves in an elliptical motion. All components that need to be autoclaved such as the handpiece and tip need to be autoclaved. 


When it comes to teeth hygiene, only a few dental instruments can compete for the efficiency of an ultrasonic scaler. The ultrasonic scaler was first used in dentistry treatment way back in the 1950s. This days technology has advanced by far better mature and well-tested equipment. When handled with people who are highly experienced, these high-tech devices have the ability to flush and destroy bacteria along with hard solid deposits that are embedded in your toothbrush. 

Perhaps there are high possibilities that you are familiar with ultrasonic scalers or probably your teeth are. Whether it’s occasionally used or on a daily basis, nearly all dental professionals are familiar with the ultrasonic and sonic technology in some levels. The ultrasonic scalers have turned to be tools of choice for many dentists. So, why? The reason is simple. The ultrasonic scaler is excellent when it comes to removing of dental plaque, build up stains and calculus from the crown of teeth surfaces. Given that wiping away of plaque and calculus eliminates the harmful bacteria that is beneath the gum line, the ultrasonic scaler is a principal means for prevention of gum disease. 

Well, but how does one use the ultrasonic scaler? It’s important that you as the patient understand how these powerful instruments work. Therefore, the following article takes you through on how to use the ultrasonic scaler.

The working of the ultrasonic scaler

The ultrasonic scaler operates at a low frequency of approximately 3,000 to 8,000 cycles per second. This represents the number of times the tip comes into contact with the tooth. The sonic scaler is usually air-driven, and its tip moves in an elliptical motion. The ultrasonic scaler is made with a handpiece that makes use of the magnetostrictive technology. The magnetostrictive inserts operate at a frequency of 25,000 to 30,000 cycles per second. Just like the sonic scaler, it has an elliptical motion. When the voltage turns low, the magnetic signal triggers the tip movement. 

How to use ultrasonic scaler

Before starting to use the ultrasonic scaler, first, ensure that the scaling unit is well disinfected. All components that need to be autoclaved such as the handpiece and tip need to be autoclaved. The scaling unit is then covered with a plastic barrier. Flash the handpiece and water lines for about two minutes to decrease the number of micro-organisms found in the line. Ask the patient to rinse the mouth for 1 minute using an anti-microbial agent like 0.12% chlorhexidine to cut down the bacterial load in an oral cavity. The clinician, as well as the assistant put on the protective glasses and with a high-speed evacuation, is used to reduce the percentage of aerosol contamination on the teeth.

Usually, the sonic and ultrasonic scalers involve using a different technique when compared to hand instruments. Most frequently the contra angularly curved scaler tips are always used for debridement in these scalers. When using it, first let the tip of the insert rotate in a probe in a manner to assess the morphology and dimensions of a periodontal pocket. Then the tip is now moved in a systematic style while doing serpentine overlapping tractions. When done with the removal of the calculus, just in case irregularities are remaining on the root surface then use a curette to remove the defects.

Well, that is how the ultrasonic scaler is used. It remains one of the best techniques for non-surgical periodontal therapy.
