What Features does a Dental Compressor Need to Have

Nowadays, the dental air compressor is most likely not your main concern when going to the dentist for your yearly check. But studies have shown that the air that your dentist uses to blow dry your teeth isn’t always very healthy for you.  A whole range of oil-free compressors is available on the market. Oil-free compressors have the big advantage that they are 100% oil-free, so there is zero chance of oil in the compressed air system. Why first contaminate the air, to clean it up again later with filters, when you can create clean compressed air with an oil-free compressor?

The oil in oil-lubricated compressors will create a protective film of oil inside the air receiver and air piping. But still, an oil-free compressor would be highly favorable over an oil-lubricated one. There are galvanized or stainless steel air receivers available nowadays, as well as plastic compressed air piping, which will eliminate the problem of corrosion.

Water in the compressed air is a common problem in compressed air system, and it is especially a big concern for dental air systems. For this reason, a dental compressor should be equipped with an compressed air dryer. There are different types of air dryers available, mainly refrigerated and desiccant. But I would recommend the adsorption air dryer .

Desiccant compressed air dryers will create a much lower pressure dewpoint, as low as minus 40 degrees or more. This means that the relative humidity in the compressed air system, and the absolute amount of water in the air (grams/m3) is also very low.

Besides producing clean air (no oil, no water), a dental compressor has some other features that are a must-have for many dentists.

As they are installed in a clean clinic, in a office-like environment (as opposed to an industrial environment), the compressor needs to be quiet, small and work on a standard 220 / 100 volt power outlet.

As the dentist will be busy with its everyday job of fixing peoples teeth, he won’t be very concerned with compressor maintenance. So a maintenance free compressor would be ideal.

When buying a compressor, also make sure that the output (the amount of air it can produce per minute or hour) is right for you. A too-small compressor will give you problem for the obvious reason that the pressure will drop when too many people use air at once.

New Advancements in Dental Air Polisher

The benefits of air polishing for the dental professional include less operator fatigue, less time involved than the traditional polishing technique, and improved access to difficult-to-reach areas. Benefits to the patient include less time in the portable dental chair, less “scraping,” excellent stain removal, reduced dentin hypersensitivity, and improved periodontal status.

While dental hygienists have a wide variety of experiences with and opinions about dental air polisher-everything from loving it to hating it. Patients likely have similar opinions depending on the type of device used, the powders used, and the expertise of the clinician providing the air polishing. New advancements in this technology have some pleasant benefits for you and your patients.

In fact, a study published in 2014 by the Journal of Periodontology concluded, “For exposed root surfaces, sodium bicarbonate cannot be recommended.” It revealed that even five-second exposure with air polishing devices using sodium bicarbonate powder showed considerable surface defects.

With the advent of air polishing devices designed for use with low-abrasive powders, dentists and dental hygienists can obliterate supra- and subgingival biofilm from enamel, exposed root surfaces, and restorative materials efficiently and comfortably.

Air polishing devices with sodium bicarbonate powders are effective stain and biofilm removal on enamel, and highly effective for biofilm removal in pits and fissures prior to sealant placement. But caution must be taken to avoid exposed root surfaces and most restorative materials, which limits their use on periodontal maintenance patients.

Which air polishing devices are currently designed for low-abrasive powders? The technology is rapidly changing in this area, but two companies that have air polishing devices with substantial versatility are Hu-Friedy/EMS and Acteon.

The Hu-Friedy/EMS Handy 3.0 Premium Package is new to the market this year. It includes the PERIO-FLOW handpiece with disposable subgingival tips that are flexible to adapt to deep periodontal pockets, and the PLUS handpiece, which removes biofilm supragingivally and up to 4 mm subgingivally. The Handy 3.0 Premium Package is a portable device that connects directly to the dental unit and uses low-abrasive powders such as glycine or erythritol and has two interchangeable dental handpieces.

Another innovative device in subgingival air polishing is Acteon’s Air-N-Go Easy. This is a portable device that connects directly into the dental unit and has four different nozzles for different clinical needs. It has the versatility of sodium bicarbonate or calcium carbonate supragingival powders and glycine powder for supra- and subgingival use. The four nozzles are the Supra nozzle using sodium bicarbonate or calcium carbonate powder for supragingival use, the Perio-Easy nozzle using glycine powder for subgingival biofilm removal in shallow pockets, the Perio-Maintenance nozzle using glycine powder supragingivally, and the Perio nozzle using glycine powder for deeper periodontal pockets.

How to Keep the Cleanliness of Dental Handpiece

We offen use the dental equipment to do the dental practice. But do you pay attention to their cleanliness? You should know it is very important. Today we talk how to keep the cleanliness of dental handpiece.

Dental handpiece having means for opening and closing a chuck. A device for opening and closing a chuck for a dental handpieces has a handle portion and a powerhead assembly including a hollow driving shaft having, adjacent to its outer orifice, a forwardly outwardly tapering portion defining a small diameter rear portion and a large diameter front portion. A chuck pusher is held in a socket member with a disc plate spring interposed between the socket member and the chuck pusher, and the pusher is movable for axially displacing the chuck to hold or release the dental tool.

Wipe down the handpiece with a damp disposable cloth. If there is still some bioburden left on the handpiece, clean under running water using a brush. A mild detergent is acceptable. Be sure that all bioburden is removed before proceeding to the next step as it can act as a protective sheild for microorganisms in the dental autoclave.

Using a pen droplet oiler (Pen Oil), insert 2-3 drops of oil into the drive air tube.  Insert a drop of oil into the chuck and speed ring (if available) of the handpiece. Because there are many different types of motors in the industry,  this image (left) guides you to how much lubrication to apply and to what parts of the dental micro motor. Approximately once a month or whenever you see a lot of debris build up; be sure to clean the handpiece threads with a paper towel and isopropyl alcohol. Wipe down the exterior of the handpiece with a dry towel to remove any expelled fluid or debris. The handpiece should be completely dry at this point.

Unused handpieces and handpieces which had been exposed to clinical dental procedures were contaminated with Streptococcus mutans, exposed to steam or ethylene oxide, and flushed with sterile saline. Washings were plated on mitis-salivarius agar, and colonies identified and counted. This data suggests that a substance entrapped within ‘clinical’ handpieces (possibly the biofilm) may protect bacteria from ethylene oxide gas, preventing adequate sterilization.

One used dental handpiece from each hospital or department of stomatology in general hospital selected was detected for possible contamination of bacteria by aerobic bacterial count and CONCLUSIONS: dental handpieces without anti-suction should be replaced soon by those with it or comprehensive dental unit with anti-suction device should be used. Used dental handpieces must be sterilized effectively before next use. Awareness on prevention from cross-infection should be improved for dental-care professional staff and operation of sterilization should be standardized.

What’s the Advantages of Different Curing Lights

Without question, light-curing is desirable, but practitioners are confused about the most appropriate light-curing concept to use in their practices. Because of this confusion, some practitioners have continued to use older lights in spite of the advantages offered by some of the newer ones. The light-emitting diode, or LED, concept is challenging more established modes of curing, and some dentists are buying LED lights. And many practitioners who have purchased the even faster plasma arc curing, or PAC, lights are not willing to go back to the slower LED light-curing method.

Since the late 1970s, halogen lights (such as the Optilux 500, Kerr, a Division of Sybron Dental Specialties, Orange, Calif.) have been in constant use in dentistry. They have served the profession well, they are a known entity and they are easy-to-use, relatively reliable devices.

The advantages of conventional halogen curing lights:

– Some cost less than other light systems.
– They are based on a simple technology.
– They generate little or no heat.
– Their technology is well-known and nonthreatening.

In the last few years, there has been an emphasis on enhanced conventional curing lights to provide greater curing intensity and faster cure. The most obvious way this has been accomplished is by the use of light guides that diminish in size as they exit from the curing light. The Turbo Tip (Kerr) exemplifies this concept. Numerous enhanced halogen curing lights (such as the Optilux 501, Kerr) are on the market, and they have been popular choices for practitioners.

The advantages of  enhanced halogen lights:

– They offer a faster resin cure.
– They operate via a known, proven technology.

Recently, a new concept to dentistry, the LED, has entered the market. There have been significant sales promotions from the several companies selling LED lights. As a result of the promotions, dentists appear to be more confused than before.

The advantages of LED curing light:

– LED lights are cordless, small and lightweight.
– Diodes are long-lasting without the need for frequent replacement.
– They generate no heat during curing.
– They offer a moderate curing time of about 10 to 20 seconds.
– They are quiet in operation.

Some practitioners have reported that the rapid cure afforded by PAC lights causes damage to both resin-based composite restorations and the tooth preparations. Although this subject has been debated for several years, current clinical usage, as well as research, have disproved the allegations of damage caused by the faster lights.

The advantages of PAC Lights:

– Curing time averages three seconds for a typical shade A2 resin-based composite restoration.
– The time savings observed with PAC lights amounts to a significant sum of money over a year’s use.
– Short curing time makes overall procedures shorter and more Dental Products,Dental Supplies integrated.

The Four Points You Should Know When Choosing Dental Equipment Supplier

Do you want to buy the best quality dental equipment? if yes, then you should know the importance of choosing a good dental equipment supplier. Choosing the ideal dental equipment supplier is essential for getting quality products at affordable prices. You must consider the four points when choosing a dental equipment supplier:

1. Purchasing Convenience

If you’re looking for a dental equipment supply company, find one that offers convenient purchasing options. Do you like to shop online for the equipment that you’re looking for? Online shopping can make the experience convenient as long as there are payment options available to fit your needs. Catalogs are also ideal, but they don’t always list the most up to date information about the available products. Consider the way you like to shop and if the supply company offers that option for you before you make your final decision.

2. Quality is the first priority

Not surprisingly, dentists invest in the best quality dental instruments as it determines the quality of patient care. Dentists choose the best teeth whitening lamp, sterilizers, dental air compressor, amalgamators, drills, dental suction unit and other tools they need.

Prior to the purchase, a lot of research goes into finding the right supplier to compare costs, support and service and select the ones that suit their needs. These days, much of this research can be accomplished via the internet. Although it is easy to get brochures describing the various instruments, Dentists prefer to check the dental instruments personally before they decide to purchase them.

3. Knowledge and Expertise

One of the most important things you’ll want to consider when choosing a supplier is the knowledge and expertise of the staff. When you call them, can they answer all of your questions about the products they offer? Do they instill a sense of confidence in you by being experts about the products they sell? The workers should be knowledgeable about their products so you call anytime and get answers to any of the questions you have.

4. Inventory

When choosing a dental equipment supplier, you want to choose one that has the products that they offer in their inventory. When you call for a particular piece of equipment, it can be frustrating if they don’t have it in their inventory when you need it. It can be even more frustrating if that happens all the time. Ask your potential dental equipment suppliers if they have all of their items in stock most of the time or if they have to get them from somewhere else. If they have to go somewhere else to get the supplies, you should choose a different supplier.
