Zahnstein entfernen: Wie lässt sich vorbeugen?

Die Routineuntersuchungen beim Zahnarzt, bei der Du Dir den Zahnstein entfernen lassen kannst, sind ein erster wichtiger Baustein für eine gesunde Mundhygiene. So erkennt Dein Zahnarzt bei dieser Untersuchung sowohl den Zahnstein als auch andere Erkrankungen und kann diese rechtzeitig behandeln. Eine Zahnsteinentfernung pro Jahr wird daher auch von den gesetzlichen Krankenkassen übernommen. Natürlich besteht aber auch über diese jährliche Behandlung hinaus die Möglichkeit, Zahnstein entfernen zu lassen. (ultraschall zahnsteinentferner)
Weitere Behandlungen musst Du jedoch selbst tragen. Die Kosten hierfür liegen mit festgelegten 13,39 Euro pro Zahnsteinentfernung jedoch in einem überschaubaren Rahmen. Darüber hinaus bieten Zahnärzte auch professionelle Zahnreinigungen an, die über die einfache Zahnsteinentfernung hinausgehen. So werden Verfärbungen und Ablagerungen gründlicher entfernt, die Zähne poliert und mit einem speziellen Flouridlack behandelt, der den Zahnschmelz besonders schützt. Derartige Behandlungen machen durchaus Sinn und unterstützen Dich bei der täglichen Zahnpflege. Allerdings musst Du die Kosten für eine professionelle Zahnreinigung, die sich von Arzt zu Arzt unterscheiden können und etwa bei 50 Euro pro Behandlung liegen, selbst tragen. Die wichtigste Methode, um Zahnstein zu entfernen, bevor er entsteht, ist jedoch die tägliche Zahnpflege zu Hause. So solltest Du Deine Zähne mindestens zwei Mal täglich gründlich putzen, um weiche Zahnbeläge zu entfernen, bevor sie sich zu Zahnstein verhärten können. Eine elektrische Zahnbürste ist hierfür am besten geeignet. Doch auch Handzahnbürsten mittlerer Stärke bringen bei der richtigen Putztechnik gute Ergebnisse. Jeder Putzvorgang sollte mindestens drei Minuten dauern. Da Zahnstein auch in den Zahnzwischenräumen entstehen kann, empfiehlt sich darüber hinaus der Gebrauch von Zahnseide.

Gehe regelmäßig zum Zahnarzt, damit er Deinen Zahnstein entfernen kann! Auf diese Weise beugst Du schlimmeren Erkrankungen wie Karies und Parodontose wirkungsvoll vor. Doch auch zu Hause kannst Du einiges tun. Schon zehn Minuten pro Tag für die Pflege Deiner Zähne reichen aus, um Deine Mundhygiene deutlich zu verbessern.

What other features does a dental compressor need to have?

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.

But a too big compressor can also cause problems. If the compressor is so big that it only runs for 5 minutes a day, every other day, than problems with corrosion can occur, as the compressor never gets the chance to run for some time and get hot. It’s like when you lie in your bed all day for a year… you’ll get slow, lazy, tired.

Installation location: important!
A dental air compressor is typically installed in one of two locations: a small one inside each chair, or a big one in a central location.

Often, the location of the compressor is not given too much though. Many times it’s installed in a boiler room or basement. Don’t do this.

The quality of the air produced is as good as the quality of the air that is sucked in. In a hot, damp boiler room, or in a cold and damp basement, the chances of dirt water an bacteria growth in the compressed air system is much higher.

Install the compressor in a place where it can suck in clean air and where you can easily reach it for maintenance. Dental compressors are so quiet nowadays, that there is no need to hide it in the basement anymore.

Compressor permits
In some countries or states, a compressor permit is need when installing a compressor of certain size (for example a tank size of 100liters or more) or pressure rating (for example more than 13 bar) inside a residential area. Please check with your local authorities if this is the case in your area.

Certification
In some countries it is required that the dental compressor has the right cetfiication. For example TUV, CE, AOTC or ISPESL. Please check with your local authorities.

What you should know before purchasing curing light

The selection of a curing light for sale that fits your style of practicing remains one of the most important equipment purchases you will make. If you have an active restorative practice, it is a device that you use virtually every time you treat a patient. The right light can help you achieve success, while the converse is true – the wrong light can make your efforts more tedious and your results less consistent.

Dental curing lights allow us to initiate the polymerization reaction “on demand” for a vast array of materials. However, there is, perhaps, more misinformation and hype regarding this type of equipment compared to just about anything else we use on a daily basis. Most of these controversies center on how long you have to cure specific types of restorations as well as how deep you can cure specific types of materials.

Manufacturers continue to make outlandish claims of their curing capabilities, most of which fall into the “too good to be true” category. An example is the claim that a new light can accomplish a “5mm depth of cure in 3 seconds”. Please don’t be fooled by these ads – you absolutely, positively cannot cure a composite in three seconds. Period. End of discussion.

If you undercure a restoration, for example, you may not even be aware of the negative sequelae for years. Therefore, selecting a curing light and using it properly can greatly affect the performance and longevity of your restorations.

Types of Dental Curing Lights
Halogen
Use a halogen bulb as the source of light.

+ Reliable – long track record

+ Cures all materials due to wide bandwidth (400nm-510nm)

– Requires a cord due to power consumption

– Cooling fans are necessary and can be noisy

Plasma Arc
Bulb is really an aluminum oxide, high pressure vessel, which contains highly energized xenon gas (plasma) under 150psi. The inside shape is specific to reflect light arcing between two electrodes. Arc is only about 1mm long, enabling a very focused beam.

+ Very fast (when a small tip is used)

– Expensive

– Large base units

– May not cure all materials

– Requires a cord that may be liquid-filled, may be stiff, and can degenerate over time

Argon Laser
Generates light when energy is applied to an atom raising an electron to a higher, unstable energy level. Electron will return to stable level by releasing light through a medium of argon gas.

+ Fast

– Very expensive

– Large base units

– Small tips

– May not cure all materials

– Require a cord due to power consumption

LED (Light Emitting Diode)
Special diodes (electronic devices that restrict current flow chiefly to one direction) that emit light when connected in a circuit.

+ Cordless or corded

+ Lightweight

+ Small

+ Long battery life due to the low power usage

– May not cure all materials

– Some have poor and/or no selection of tips

– May shut down due to overheating during long curing intervals

Types of Dental Autoclave Sterilizer in Dental Setting

It is vital that the type of sterilizer being used is clearly identified as this dictates not only what can be processed in the chamber but also how the machine is tested and validated.
When purchasing a new machine the cost is obviously a focal point. What is often not apparent is the ongoing cost of validating the machine after purchase. This is particularly essential when purchasing a vacuum sterilizer.

Autoclave Class B STERILIZER
For example, HTM01-05 daily steam penetration testing can cost a few pence per day for some B type sterilizers totaling under a hundred pounds for the year. Some S type sterilizers however can cost several pounds per day totaling several hundred pounds per year for the same test. The cost saving on initial purchase can be quickly eclipsed by the ongoing cost of validation.
Autoclaves commonly sterilise by exposing its charge (items to be sterilised) to elevated temperatures of 121 to 134ºC under pressure of 15 to 30 psi, for a holding time of anywhere between three to 30 minutes. Please note that the three to thirty minutes time is the holding time at the set elevated temperature and not the total process or cycle time. Total cycle time would be far greater. The combination of the three lethal parameters of time, temperature and steam, deliver a powerful kill rate which even the hardest of bacteria find hard to survive. This effective and yet clean method of lethality is unmatched by any of the other methods of sterilisation.
Saturated steam at this temperature is an excellent carrier of heat. The operative word is saturated steam. The steam condenses onto its charge and as it does so, it not only expands its huge latent heat but also draws in additional steam to replace the condensed steam. Thus, the heat transfer is very efficient and the penetration levels extremely high.
However, if there is residual air in the chamber and load, it will interfere with steam-instrument contact and may compromise sterilisation. This residual air can prevent penetration of steam to the depths of the load, leaving your sterilisation incomplete. When you load the autoclave with instruments and close the lid, there is already a lot of stale air trapped inside. For sterilisation to take place, this air needs to be effectively purged and replaced with saturated steam. To resolve this problem of purging entrapped air, normal dental autoclave sterilizer will have a manual, mechanical or electrically operated valve open till about 100ºC. Once it is closed, the pressure and temperature begins to rise. It is presumed that by this time, the entire entrapped inner air has been purged. However, tests have shown that this is not an effective method for vials, wrapped items, implants, garments and certain types of hollow ware. You can never be assured of efficient penetration of steam right inside, if you are using a regular autoclave. Even a small volume of entrapped air can compromise your sterility assurance level simply because ordinary entrapped air is a very bad conductor of heat and moisture. These pockets of air cannot conduct heat to the load with the same vigour as steam and therefore cold spots remain within the load.

How to choose an portable dental implant unit?

Implant unit motors are necessary equipment for placing dental implants. They are composed of a bracket, a pedal, a marathon micromotor and a contra-angle which is connected to the micromotor.
Most manufacturers recommend their own implant unit, but they are independent from the dental implant itself. As a result, you can choose any implant unit you like, no matter which dental implant you use. Moreover, following a little research, you can find motors with a good value for money.
There are several manufacturers specialized in the manufacturing of implant portable dental units such as Bien Air, Nouvag, NSK, Mariotti, W & H etc. All these brands can supply you with machines able to perform surgeries with full guarantees. However, you need to make the appropriate choice according to your needs.
Factors to consider in choosing a micromotor:

Function
Basic functions such as clamping and speed control are available on all engines. However, some extra features can be offered according to your needs. For example, some implant engines have programmes to set up the drilling protocol for each implant or getting the hardness of the bone that you’re milling.

Incorporated Lighting
Some units have an incorporated light or LED on the head of the contra-angle. This function enables you to see much better during procedures. Obviously this has a cost and, for this reason, you need to assess whether this feature is needed.

Type of Pedal
There are models with very simple pedals that control only the on/off button, but there are other much more complex pedals with three or four buttons that control different functions.

Tightening of Torque
The maximum tightening torque of the motor is a very important criteria to consider.

Warranty& After Sales
Another critical point to consider is whether the dental implant equipment has a warranty and after sales/repairing service. Most of the manufacturers offer a warranty of one or two years. If the manufacturer does not have a technical service in your country, you may have to find a good technician for repairs. We recommend that you buy 2 units so you have a spare one if the main one is out of service during a surgery.

Price
The price of the micromotor is directly proportional to the incorporated functions. So if you want to save, you can go for basic technical features excluding lighting or complex programming modes.

Accessories
Finding irrigation lines that are compatible with the engine is very easy and price may be a point to consider when choosing a motor.

What Should Take into Considertation in choosing portable dental units?

Portable Micro Motor M1 25,000rpm Features

A Comparison Between Air Driven and Electric Dental Handpieces

Electric Handpiece Gains Ground in The Clinic
The comparison issue is raised more as the electric handpiece gains ground in clinical use. Coupled with it’s ability to incorporate attachments geared to produce speeds to 200,000+ rpm, the electric handpiece makes a strong bid for its place in the clinical arena. While air driven handpieces typically win the speed race (350,000+ rpm), another variable is introduced – Torque.
Remember, Torque is a measure of how hard something is working, and Watts tell us the rate at which the work is being done.
The average high speed handpiece develops 16 to 17 Watts. To reach this level, it must obtain and hold it’s optimum speed. As the turbine slows, the air driven handpiece loses a portion of it’s ability to cut, as the power output of the handpiece (Watts) decreases as well.
Modern brushless electric motors have the ability to maintain constant torque over practically the entire speed range, so the power output of the handpiece (Watts) is more consistent as well. The Kavo electric handpieceElectroTorque brushless electric motor ranges from 20,000 to 40,000 rpm. Coupled with a speed increasing attachment, it can maintain constant torque between 27 and 200,000 rpm.
So, are we going to go out and buy all new electric setups for each operatory? The cost alone would probably preclude that. Air driven handpieces will likely maintain their place for quite some time. At less than $1000 for a good one, with no other attachments required, the cost is a little easier to swallow.
Weight is another issue. Air driven highspeed handpieces are still a bit lighter and easier to handle. Modern air driven handpieces are beginning to develop much greater torque as well.
electric handpiece
Learning to use an electric handpiece is worth the effort
The electric low speed contra angle handpiece has definitely come a long way, and certainly deserves it’s place in the modern practice. With a little patience, learning to use this newer technology can pay off. There is a learning curve, but not too steep. One large advantage, for the progressive practice, is a quicker patient turnaround, as cutting is a bit faster. Electrics also tend to last a little longer between repairs, which helps to offset the initial cost.

What are important characteristics in choosing portable dental Units?

Important considerations for an effective portable dental delivery system include:

Transportability (how easily it can be moved and utilized):
>weight and size characteristics
>ability to transport the equipment (cubic feet needed — will it fit into your vehicle?)
>carrying case and/or dolly system (is there a built-in handle and/or dolly system? If not, can you utilize generic cart systems effectively to move equipment?)
>capacity to selectively take only the dental equipment you need
>ease of moving the assembled equipment
>capability of transporting equipment into various settings (e.g., up/down stairs, through narrow doorways)

Durability (likelihood of malfunction because of constantly moving the units):

>protective carrying cases
>protective padding systems for lights and other delicate equipment
>equipment engineered sufficiently to minimize need for frequent repairs
>avoiding need for repairs

Ergonomic characteristics (creation of an efficient working environment):
>favorable relation of portable dental unit functions to weight and size
>dental chair allows variety of positioning options (e.g., height and reclining angle); movable arm rests to allow wheelchair transfers
>adjustability of operator and assistant stools
>convenient location of handpieces, suction, water and air syringe, and rheostat (foot pedal)
>dental light positioning flexibility for illumination
>dental x-ray unit weight, stability and positioning (stationary tripod bases are less effective than a concave base on wheels that facilitates better x-ray head positioning)
>portable delivery system layout matches available room layouts (equipment should be small enough and flexible enough to be used in a variety of spaces)

Delivery system capabilities (capacity for effective dental treatment provision):
>ability to provide a range of dental services(should also allow for 4-handed delivery of care–dentist/hygienist and dental assistant working together on the same patient)
>portable dental unit provides adequate sustainable pounds per square inch (psi) for high-speed and low-speed handpieces (35-50 psi is recommended for handpiece operation)
>portable dental unit provides adequate sustainable cubic feet per min (cfm) for high-volume and low-volume suction (2.5-5.0 scfm)
using the handpiece and portable dental suction unit at the same time is possible and does not cause a decline in the functional capabilities of either feature
>supports multiple handpieces

>supports an ultrasonic scaler
>supports fiber optic capability for handpieces to improve visualization of the mouth in settings with less ambient light
>supports air turbine, electric, and/or cable handpieces

dental light should be quartz halogen-based and provide adequate foot-candles for illumination (should provide about 1000 ft candles at working distance of 2 ft)
sufficient suction and water bottle capacity–at least 500 ml (larger size will decrease frequency of emptying the waste or refilling the water bottles)there is an adequate air reservoir to provide continuous sustainable power to the handpiece (1-9 liters with larger capacities preferable to minimize the running of the compressor)

Infection control (meeting OSHA’s requirements for cleanliness and asepsis):
>cleaning and disinfection of the unit
>flushing handpiece and waterlines
>ease of removing suction contaminates from the vacuum to the drain and disinfection

Maintenance (how to avoid “downtime”)
> extent and frequency of preventive maintenance activities (e.g., cleaning, flushing, lubrication
ease of performing needed maintenance and minor repairs (e.g., replacing gaskets, filters, hoses, and/or fuses)
on-site repair capabilities
>repair of more complex problems and need to ship components for servicing or repairs
> loaner unit availability from vendor when extensive repairs are needed

Ease of assembly/disassembly (starting and finishing):
>time and effort needed to set-up unit(s)
>time and effort needed to clean and disassemble unit(s)

Noise level (how loud is it and can it be modified):
Dental compressor and vacuum noise–sound levels may range from 40-70 decibels at 3 to 4 feet (if noisy, check on compressor capability to be placed some distance away from the treatment area; oilless compressors are generally louder than non-oilless ones; check other variables such as air reservoir or continuous flow versus an intermittent flow design)

Why Dentists Use a Dental Suction Unit?

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. In response to Jeanny’s question, 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 dental suction unit 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.

To Help the Dentist See
As I mentioned in a previous article about the dental drill, the drill that dentists use to do fillings sprays out a lot of water to keep the tooth cool and clean. Unfortunately, that water can quickly build up in the mouth and get on the dental mirror. In order to ensure that the dentist can see the tooth while working on it, it’s necessary to use the high volume suction to suck away all of that debris.

Those are the four main reasons that I came up with as to why dentists use the Portable dental suction unit. In conclusion, let’s take a look at a question that I asked my dental hygienist as a child.
