Dental plaque, a bacteria film that usually forms on the teeth is the major cause of gum disease (periodontal). When bacteria settles on the teeth, a whitish film known as biofilm is formed and if not removed, it can lead to the formation of pockets; separation areas between teeth and the surrounding gums where plaque hardens into deposits called tartar or calculus.

The main reason for having the teeth regularly cleaned by a professional dental hygienist is to have the calculus and plaque deposits removed. Removal of the deposits is known as scaling which can be done using either hand held scalers or ultrasonic power scalers.

How ultrasonicpower scalers work

Power scaler’s main action is mechanical; they use ultrasonic vibration energy to remove and crush the calculus deposits. Other actions are; creating shockwaves to disrupt bacterial cells or using turbulence to disrupt the biofilms and irrigation; therapeutic flushing and washing of gum pockets as well as the root surface with cooling water. One should obtain proper training on the use of ultrasonic power scalers so as to effectively remove the deposits and promote healing.

Pros of using ultrasonic power scalers

According to research, the use of ultrasonic power scalers has the following advantages:

· They are as effective for use as manual instruments for the removal of calculus in shallow gum pockets but they are more effective in gum pockets which are greater than 4mm.

· They are effective in disrupting biofilm from the root surface and within gum pockets which makes them very helpful especially when patients require frequent cleanings or teeth maintenance.

· Their specially designed tips can penetrate deep in the periodontal pockets compared to manual instruments. They are also more effective in cleaning the difficult crannies and nooks like furcation; the area where the roots join in multi-rooted teeth.

· When properly used, they are kind to the structure of the tooth which is important in repeated cleanings.

· The coolant spray provides irrigation; flushing of the affected area hence promoting healing by getting rid of the bacteria and other bi-products. It also allows the dental hygienist to see when scaling.

· It takes less time to scale the teeth using ultrasonic teeth scaling compared to when using manual instruments.

· The smaller tip of this instruments causes less distention of the tissue and they require just a little pressure which makes it comfortable for the patient.

Cautions when using Power Scalers

· The production of aerosol which leads to the formation of contaminated mist. To prevent this, one should wear protective equipment.

· Ultrosonic power scalers can affect some cardiac pacemakeers. Though the modern cardiac pacemakers are shielded from this, if you have one, you should inform the hygienist or the dentist before purchase or use.

· The use of ultrasonic power scalers is not recommended for patients with hypersensitive teeth including the newly erupted teeth and the primary teeth. Inform the dentist if your teeth are sensitive to change in temperature.

· Ultrasonic power scalers should not be used in areas off demineralization, composite or porcelain restorations or titanium implants unless you use tips which are specially designed so that they do not scratch them.
