The Use of Dental Suction Units

There are two main types of dental suction unit that dentists use: the saliva ejector and the high volume suction. The saliva ejector does exactly what its name implies; it sucks saliva out of the mouth. This is the suction pictured at the upper right of this article. Many times dentists will have the patient close down on this suction so that it can suction away any remaining saliva in the patient’s mouth.

The other main type of dental suction that we use is the high volume suction. This suction is so strong that the dental assistant simply holds it close to where the dentist is working and it will suck away any nearby debris, much like a strong vacuum cleaner can suck away crumbs without actually touching them.
Why Dentists Use a Dental Suction

Now that the introductions are over, let’s talk about some of the different reasons why dentists will use a suction.
For Patient Comfort

Keeping the patient comfortable is a high priority. We suction after giving anesthetic because the anesthetic has a bitter taste, and most patients prefer to rinse out with water and use the saliva ejector. Also, if the anesthetic sits in the back of your mouth for too long, it may start to slightly numb the back of your mouth and could give the patient a gagging sensation.

We will also use the suction to make sure that you don’t get too much water in your mouth while we are working.
To Clean Away Any Excess Dental Materials

When a dental hygienist cleans and polishes your teeth, you can get a lot of cleaning paste in your mouth. We use the suction to help clean all of that away. Also, when dentists are do amalgam fillings, pieces of the soft amalgam can sometimes fall away from the tooth surface. We use the suction to help whisk them away.
To Keep the Tooth Dry

During some procedures, such as white fillings, it is important that the tooth stay clean and dry. The suction helps keep the tooth dry by sucking away any saliva, blood, and water that may have accumulated around the tooth. If the cavity went below the gum-line, then it’s pretty likely that the gums will bleed during the filling.

The Costs of Compressed Air Energy

The operation of an air system requires more than just an ability to turn the right switches. One of the most important aspects of the whole operation is the maintenance of the compressor and various other components, because this ensures long life and efficiency for an air system.

One of the biggest compressed air maintenance mistakes is to underestimate or miscalculate the amount of energy that a compressor will use within the span of a year. Fact is, the price to operate a dental air compressor can equal or exceed the purchasing cost of the machine in the space of just 12 months. Most problematic in this regard is the wasteful usage of a compressed air system, which often occurs when operators are unaware of the overall energy costs.

On average, an industrial air compressor will retail in the ballpark of $30,000 to $50,000. When you multiply the operating costs per hour by the number of usage hours per day across 12 months, the cost of operating the machine during the first year alone could well exceed the initial price, and that doesn’t even count any possible maintenance costs.

A reliable way to estimate annual energy costs is to take the compressor’s horsepower and multiply that by .746, then multiply that by the number of usage hours, then multiply that by the power rate, and finally divide the total by the motor efficiency.

To best assure efficiency, it’s important to accurately calculate the annual energy costs of an air compressor, and to make sure that all operating staff understand how the figure plays out on a daily basis. That way, wasteful system use can be curbed going forward.

Even though the compressor is the main component of concern within an air system, it’s not the only one in need of routine maintenance. Of equal importance during any maintenance inspection are the other components that facilitate the air supply. Chief among such components is the air receiver, which holds compressed air for times when air demands increase, and also reduces system wear and contamination.

The air receiver makes it possible to run the compressor at lower levels and conserve energy in the process. However, the air receiver won’t be able to do its job properly if it’s too small for the system, because the compressor will have to run longer than necessary to keep up with air demand. Therefore, it’s important to ensure that the air receiver is either large enough for the system, or backed with secondary receivers.

The Difference Between Traditional Handpiece and Electrical Handpiece

One of the most fundamental devices used in dentistry, the handpiece can enhance the efficiency of everyday dental tasks. Through the years, handpieces have gradually been redesigned and upgraded to become the highly accurate and sophisticated tools they are today. Technological advances continue to improve these indispensable dental equipment.

The dental handpiece is an essential element in any dentist’s armamentarium. It is a fundamental device that can enhance—or hinder, depending on its efficiency and maintenance—the daily routine of a practice. Selecting the right handpiece is critical to helping ensure the smooth operation of everyday activities. The two primary types of handpieces—air-driven and electric—have unique characteristics with specific benefits and drawbacks. Both can achieve excellent results, therefore it is important to understand the differences and advantages of each.

Speed and precision are two things that you should look for in a handpiece. The better your handpiece, the smoother the day-to-day operation of your dental practice will be. There’s many different kinds of handpieces. How do you select the one that’s right for your practice?

Traditional handpieces use an air-driven turbine to facilitate the rotators. These have a lighter weight and a skinny design, making them easy to work with. While turbine handpieces have many advantages, they can also cause higher levels of “noise” as the handpiece ages and the bearings wear down.

Electric handpieces (with variable revolutions per minute) are also available that give dentists added benefits when compared to their traditional air-driven counterparts. One significant difference is having a specific RPM, with constant torque and less “bur chatter” (more concentric), so that when polishing or cutting through various types of tooth structure or restorative materials, the bur does not “bog down” or slow down when performing the clinical task. In many clinical situations, an electric handpiece can perform the same functions that both an air-driven high-speed and separate low-speed unit can.

Since most clinicians still prefer individual handpieces for high and low speeds so they can be more efficient chairside, this may not make a difference when choosing between the two systems; however, the higher initial investment for electric handpieces may be a consideration for some clinicians. Also, given the ability to “dial in” the desired RPM and use different contra-angles that have different gearing ratios, the electric handpiece can be custom-tailored to perform many other types of clinical procedures such as rotary endodontics, implant placement, and third molar removal (via tooth sectioning), for example. This clinical versatility is very desirable in today’s dental practices where multidisciplinary treatments are becoming increasingly common.

Electrical handpieces operate at both high and low speeds. This makes them versatile for all kinds of procedures. Instead of bearings, this handpiece has gears instead of bearings. These handpieces are quieter due to the fact that air is not flowing through them for power.

What Should You Know about the Dental Air Polisher

Although air polishing has only recently become a common option for dental patients, it’s a concept that’s been around for quite a while. Over the past few years, techniques have been perfected, and dental air polisher is now believed to be a very safe, effective, and efficient way to remove stains from the teeth, although it’s important to remember that air polishing methods may not be suitable for everyone.

Air polishing is just that – it’s the practice of polishing the teeth using a stream of air that’s directed onto them. Some air polishing machines may also use a stream of water. The air works in two ways. Firstly, it ‘blows’ onto the teeth and gums to remove any buildups of dirt, and get rid of any food that may have become trapped, which is especially common if you choose not to floss. Secondly, it blows an abrasive powder onto the teeth which helps to tackle stubborn stains such as tea and coffee.

Which is better: air polishing or traditional polishing? Well, that’s a difficult question to answer. When the most suitable polishers are used, there really shouldn’t be any differences in the overall result, but some people do prefer air polishing simply because it’s the newer option. But it’s not for everyone.

One of the biggest concerns with air polisher is the use of sodium bicarbonate as an abrasive. It’s reported that 1 in every 3 adults in the US suffers with hypertension, or high blood pressure, and many are advised to adhere to a low sodium diet to help keep symptoms under control. The use of sodium bicarbonate, which has a high salt content, could potentially be risky for some dental patients. A number of clinics are now using calcium carbonate instead, so this is worth checking with your practice.

In supragingival polishing, the powder of choice is usually sodium bicarbonate which is abrasive and helpful with the removal of heavy stains and soft deposits above the gumline. With subgingival air polishers, the tip is specialized to be able to effectively enter the periodontal pocket and deliver a very low abrasive powder. The powder of choice with subgingival air polishing is Glycine. Glycine is an amino acid and is significantly smaller in particle size than sodium bicarbonate. It appears to have an active role in the disruption of bacterial recolonization making it both preventive and therapeutic.

Another concern is that air polishing could reduce bond strengths on tooth restorations, and so it is generally advised that patients with restorations stick to traditional polishing techniques using dedicated nanocomposite polishers which are not only safe to use on restorations, but also provide a great finish.

Overall, air polisher can be good to try, and you may find that you prefer this over traditional polishing methods. However, if you are unable to use air polishing for health reasons, don’t worry. Traditional polishing techniques can be equally as effective, leaving you with smooth, shiny, and healthy teeth.
