The Reason for Choosing Dental Air Polishing

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.

There are two powders that are commonly used for air polishing by dental air polisher, and these are sodium bicarbonate and glycerin powders. These are chosen because of their excellent abrasive qualities. Think about when you’ve got a dirty pan in your kitchen – you may use sodium bicarbonate (baking soda) to remove the stains. It’s exactly the same when it comes to your teeth; sodium bicarbonate can help to get them clean.

A powerful yet controlled jet of water, air and fine powder not only polishes all the surfaces of a tooth, removing plaque, discoloration and soft deposits, but also reaches deep into periodontal pockets up to a depth of 5 mm. It is far more efficient than traditional scrape and polish treatment at removing the damaging biofilm that develops when dental plaque is colonized by bacteria and can cause periodontitis and peri-implantitis to develop. Air flow polishing is completely safe to use with dental implants, veneers, crowns and bridges.

Anyone who has ever cringed as a scraping tool digs into their gums or a polishing disc presses onto tooth enamel will welcome air polishing for its painless, fast and non-invasive method of cleaning. Even deep pockets and interproximal areas are easily reached without uncomfortable and potentially damaging probing by curettes and scrapers and with no instrument contact, the technique does not generate any heat or vibration. The non-toxic powder used in air polishing is also more pleasant and less gritty than the heavy paste used in traditional polishing. Air polishing powders with added flavors, such as spearmint, have even been developed for use in machines, making the experience even more pleasant.

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 air polishing 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.

The Importance of Dental Sterilizer

Today’s busy dental practices face a serious challenge: to maintain or increase productivity while ensuring that patient safety remains a top priority. At times, these may seem like incompatible goals. Advances in dental processing equipment, however, have empowered practices to develop safer processes while realizing efficiencies and ultimately, saving money.

Sterilizers are medical devices, requiring clearance by the Food and Drug Administration before manufacturers may offer them for sale. The FDA requires rigorous testing to ensure an adequate margin of safety in each cycle type described in the instructions. Failing to follow the instructions of the manufacturer is ill advised, since it may result in inadequate sterilization of the instruments or devices in the sterilizer. It is never appropriate to use a household device, such as a toaster oven, for sterilization of dental equipment.

A cleaning and sterilization process that meets ADA and CDC guidelines is vital to an effective infection control program. Streamlining of this process requires an understanding of proper methods, materials, and devices. Many methods of instrument reprocessing are available. Use of a complete system that encompasses and fulfills all elements that are critical maximizes efficiency and minimizes risks. Closed cassette systems provide a more efficient and safer way to process, sterilize and organize instruments in a dental office – these eliminate manual steps during instrument reprocessing such as hand scrubbing and time-consuming sorting of instruments, thereby improving safety and increasing efficiency.

Dry heat sterilizers have been used effectively in dental office for many years. Just as with any other sterilization method, dry heat sterilization is highly dependent upon the operator following the manufacturer’s instructions for cycle time, temperature, instrument packaging, and loading technique. Because dry air is not as efficient a heat conductor as moist heat at the same temperature, a much higher temperature is required for a dry heat unit to accomplish sterilization.

Packaging cleaned instruments prior to placing them in the autoclave sterilizer is a standard of care that protects instruments and maintains their sterility until they are ready for use on a patient. Unprotected instruments may be re-contaminated with dust and spatter or by coming into contact with any number of non-sterile surfaces during transport, storage, tray set-up, and operatory set-up.

The Importance of Dental Intraoral Cameras

Intraoral cameras have incredible technological features. With LED lighting, a head that rotates from 0 to 90 degrees, and powerful magnifying capabilities (some cameras can zoom in up to 100x), your dentist can examine your mouth in extreme detail. This means he or she can make diagnoses more accurately. The office can attach these photos to your health record to make tracking any changes simple.

Early diagnosis allows for earlier and less invasive interventions such as remineralization therapy or a preventive resin restoration. Pairing advanced diagnostics with the ability for patients to visualize their oral health conditions creates an urgency for patients to move forward with these minimally invasive treatments. Early detection creates a powerful call to action for both the dentist and patient alike.

The dental explorer is said to have an accuracy of about 25%, and traditional radiographs have been reported to be about 68% accurate, but the tooth structure has to undergo enough damage for the lesion to become visible and by that time the patient is definitely getting a filling. These traditional lesion detection modalities are simply not capable of spotting small, early pathologies. But new technologies are now available to help clinicians locate and quantify potential problems in the gingival tissues as well as the teeth.

Each feature that benefits the dentist also benefits the patient—maybe even more. Your dentist understands symptoms and conditions thoroughly, but it’s often difficult to explain precisely what is happening in a patient’s mouth using just a mouth mirror, which is small and hard to see, or an x-ray image, which takes time to print and doesn’t display images clearly.

When your dentist uses an intraoral camera during your examination, however, you’re seeing exactly what he or she sees right then. Dentists can display clear, colorful images, allowing them to point out any issues and discuss them with you immediately. You’ll certainly learn a lot about your mouth! And the more you see and understand, the more confident you can be when making treatment decisions.

The intraoral camera makes record keeping a breeze. Because the camera can take pictures of decay or the beginnings of oral health conditions, images can be printed and placed into patient files. Previously, dentists merely attempted to write an explanation of problems found during exams. Now, dentists can accurately track the progress of treatments or problems for years following a visit. Furthermore, patients can receive printed pictures of the conditions the dentist finds, which may be beneficial for filing insurance claims.

Knowing How to Maintain Dental Handpieces

There’s many different types of dental equipment that you need at your dental practice, but there’s non more important than your dental handpiece. Every dentist is dependent on the electric handpiece in order for the practice to run smoothly. .Since it’s so versatile, the tool is also happens to be quite intricate. Proper maintenance allows the handpiece to keep running safely.

High speed handpieces are also known as drills in the dental world. This tool is a power-driven tool that has speeds of 400,000 rpm and up. The drill is of course used to drill holes for fillings and assist in other types of dental work like polishing dental trays for dentures.

Electric handpiece repair doesn’t require a complete rebuilding of the tool each and every time. Most times, the parts that are causing the issues are inspected and replaced if needed.

Sometimes, factory parts are required for a repair, other times, bearings of higher ratings can be used, depending on the state of the tool itself. Each brand and variation of handpiece has a different number of bearings and gears. That’s why you need to send your most important tool to the right repair company to ensure a safe and effective repair.

Low speed handpieces rotate at reduced speeds somewhere between 0 and 80,000 rpm, depending upon the make and model. These handpieces are equipped with a speed control ring, allowing you as the user to control the speed of the ring manually.

Understanding the different types of handpieces and the parts that are involved in maintaining them. Most dental offices use high speed handpieces more often than low speed, yet both are useful. You should expect to need your high speed handpiece maintained more often due to the wear and tear on the bearings. The type of maintenance that you perform on your handpiece will also depend on the intricate parts involved on each type of tool.

The Research about Dental Air Polisher

Use of dental air polishers decreased as the clinician’s age and experience increased. Curricula in many dental hygiene schools do not include clinical instruction in the use of this polishing device due to inadequate numbers of units and difficulty in moving units between clinic stations. Inadequate or insufficient knowledge and experience, therefore, appears to be a major factor in the underutilization of the air polisher. In an attempt to provide a suitable knowledge base for practicing dental hygienists, the primary purpose of this article is to provide a comprehensive summary and critique of the research on all aspects of air polishing. In addition, a suggested technique, common concerns, and possible solutions will be discussed.

Discussions are based on a review of the relevant literature on air polishing. Tables organize the data into categories to facilitate access of needed information. Because of the various research designs employed and the number of variables that must be controlled, comparative analyses of the studies are difficult. However, where possible, analyses of the validity and reliability of the studies are provided. It should be remembered that while laboratory (in vitro) investigations are useful, the most definitive conclusions must be obtained through clinical (in vivo) studies. Case reports or opinion articles have limited applications. Therefore, interpretation and application of research results must be done with caution.

Air polishing has been compared to scaling and rubber-cup polishing for efficiency and effectiveness of stain and plaque removal. The literature overwhelmingly supports the use of the air polisher as an efficient and effective means of removing extrinsic stain and plaque from tooth surfaces. Air polishing requires less time than traditional polishing methods and removes stain three times as fast as scaling with comers. In addition, less fatigue to the operator has been mentioned as an important benefit of air polishing.

Most investigators agree that intact enamel surfaces are not damaged when stain removal is accomplished with an air polisher. Even after exposure to enamel for the equivalent of a 15-year recall program, surfaces were not altered.

in one in-vitro study, air polishing was shown to remove less root structure than a curet in simulated three-month recalls for three years. Woodall agrees that the air polisher may be preferable to curets in this situation. Since less root structure is removed, decreased root-surface sensitivity also may be a benefit.

Clinical studies to evaluate soft tissue usually provide generalizable conclusions. Gingival bleeding and abrasion are the most common effects of air polishing. These effects are temporary; healing occurs quickly and effects are not clinically significant. No complications were seen with healing at extraction sites following air polishing of teeth prior to extraction. To avoid tissue trauma, the manufacturer recommends pointing the tip of the air polisher at the facial, lingual, or occlusal surfaces, thus avoiding the gingival margins.

Patients also have noticed a salty taste with air polishing, but this was not objectionable. Covering the tongue with moist gauze may prevent irritation and excessive salty taste, as will rinsing with water, mouthwash, or a mint-flavored powder.

Dental Compressor

How to Maintain the Dental Air Compressor

A dental air compressor pressurizes atmospheric air for use in procedures. Standard compressors are not suitable for this purpose because they may not meet health and safety standards. Dental firms can choose from an array of models designed for small, medium, and large practices with a variety of features.

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. Unfortunately, compressed air maintenance mistakes are often made by operators who’ve only familiarized themselves with the basic workings of the equipment.

Common mistakes in compressed air maintenance include failure to assess energy costs and the impacts of contamination and condensation. These mistakes alone can lead to inefficiency and parts failure that can result in losses in the tens of thousands over the course of a given year. Further compressed air maintenance mistakes include a lack of attention to secondary components and a failure to properly train all members on staff of the finer nuances of compressor operation.

Compressed air should always be oil free. Nonetheless, oil serves as a necessary evil in the process of air compression. As such, the process has its share of potential consequences. As the air is compressed, oil is used for the purposes of cooling, lubrication, and sealing. Unfortunately, up to half of the degraded oil can pass through the system in vaporized form, especially when temperatures are high. The system itself can also draw unburned hydrocarbons, which condense once cooled. When acidic oil vapors mesh with moisture in the compressed air, corrosive buildup forms along the air receivers and valve cylinders.

It must be noted that dental oilless air compressors are not contaminant-resistant compressors. In other words, the inlet valve of an oil-free compressor cannot magically filter out airborne contaminants from ambient air. Just as with an oil-lubricated system, an oil-free compressor needs filtration to keep water, dirt, unburned hydrocarbons, and other impurities from the compression process.

Some manufacturers offer refurbished units which have been carefully serviced before sale. These units are similar to those that are new, but have a lower price because they’ve been gently used. It may also be possible to rent a unit, which can help defray the startup costs for a dental practice. The equipment needed to start offering services to patients can be substantial, making it expensive to start a new business.

Dental Autoclve

What Do You Need to Know about Sterilization

Sterilization in dentistry is very important, and dentists and dental assistants typically clean and disinfect most surfaces in a their offices and treatment rooms to help prevent the spread of germs. Disposable dental supplies Australia are also used whenever possible. Tools that are not disposable are generally scrubbed by hand and placed in a machine known as an autoclave. This machine then disinfects the tools by spraying them with very high-pressure steam, which kills most micro-organisms. Any tools that can not be subjected to high heat or moisture are usually disinfected with chemicals.

Sterilization is a necessary part of the maintenance of your dental handpiece. This process also puts your handpiece under the most stress with wear and tear. Maximum temperatures in your dental autoclave shouldn’t reach more than 140 degrees Fahrenheit. This can help to preserve your handpiece just a bit longer in between the need for service.

Any tools that can not be subjected to moisture or intense heat must be sterilized with other methods. Chemicals are often used during sterilization in dentistry as well. Some of the chemicals used to kill germs and sterilize dental tools are typically iodine or alcohol based, since both of these chemicals are very effective at killing germs.

Tools that can’t be thrown away, such as dental drills, are generally put through a very intensive dental sterilization process. First they are usually vigorously scrubbed by hand. This is usually done with hot water and detergent, and it helps remove any large particles, such as plaque. They may also be placed in a vibrating tray filled with cleaning solution, which can help remove very small particles.

Hot salt/glass bead sterilizers are not acceptable for the sterilization of items between patients. The endodontic dry heat sterilizer (glass bead sterilizer) is no longer cleared by the Food and Drug Administration (FDA). The FDA Dental Device Classification Panel has stated that the glass bead sterilizer presents “a potential unreasonable risk of illness or injury to the patient because the device may fail to sterilize dental instruments adequately.”

No national mandate requires such a log in a private practice dental office, but requirements in individual states can vary. For example, Indiana requires that sterilizer time(s) and temperature(s) be documented in the dental office infection control manual. Contact your state dental licensing agency to determine if similar requirements exist in your are. Because recordkeeping can play a role in risk management, it may be wise to consult your attorney for advice on maintaining such records.

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 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.
