Cofferdam, rubberdam, optidam: what is it and what is it used for

Rubberdam (cofferdam) - protective dental screen (gasket) made of latex: with its help, the doctor isolates the teeth being manipulated from the rest of the oral cavity. This ensures the sterility of the working area during root canal treatment, restoration of broken teeth, prosthetics (crowns and bridges), installation of veneers, etc.

Rubberdam is a stretchy elastic napkin 5x5 or 6x6 centimeters made of latex or nitrile (for patients with latex allergies). Some dentists prefer brightly colored sheets to increase light in the work area. Others choose dark materials so that the tooth stands out against their background.

What is hidden behind complex names and when to use these tools

Today it is difficult to argue with the fact that in dentistry the level of development of advanced technologies has made it possible to significantly improve the quality of services and bring them to a fundamentally new level. But not all patients clearly understand that dental treatment or restoration largely consists of many little details that are invisible to the average person, each of which is individually important and irreplaceable.

For example, a rubber dam in dentistry. Having heard about it, many believe that this is just another way to extract money from a patient, and do not even suspect that the product can bring significant benefits and contribute to achieving the most positive result. How? Read about this in the material prepared below.

What is a rubber dam?

So, rubber dam in dentistry - what is it? Take a look at the photo. This is a latex plastic material. The doctor first places it on the patient’s oral cavity before starting treatment, after which he makes the necessary hole to isolate the working area under one, sometimes several teeth. That is, in essence, it allows you to isolate the working field, remove all unnecessary things that may interfere.

The specialist fixes the device using a special frame or clamps, ensures the required level of lip tension and gets to work.

On a note! Have you heard about optidam in dentistry, but have no idea what rubberdam and rubber dam are? It will be useful for you to know that these are the same thing, the only differences are in the names and their translation from English. But the essence of these devices is the same - to ensure sterility and isolation of the working field.

Who invented the Cofferdam and why?

This invention is many years old.

In 1864, Sanford Christie Barnum, a young New York City dentist, began using Rubber Dam, a “special protection” to isolate a tooth requiring treatment from saliva and gingival fluid.

“Rubberdam” (or otherwise “Cofferdam”) is a thin scarf made, like disposable gloves, from latex.

Initially, the “latex curtain” was poorly fixed, but metal locks developed later for different types of teeth made it possible to hold it securely.

Over the years of use, the design has not changed fundamentally and, as before, it solves an important problem in dental treatment: it reliably isolates the surgical field from the rest of the oral cavity in order to avoid infection and moisture on the tooth being treated.

Cofferdam: long-forgotten old or new in dentistry

A rubber dam or dental rubber dam allows dental treatment to be performed quickly, reliably, and conveniently. But not everyone knows that this device is not a trend of progress at all, but a long-forgotten old one. Thus, the product was first presented to the public more than 100 years ago. It was invented by an American dentist: in those days the system was successful, but was gradually forgotten by doctors. This happened because it did not directly affect the outcome of treatment, plus it increased material costs. Therefore, only a small part of doctors were ultimately inclined to use it, and then it was used only for endodontic treatment.

Today, increased demands are placed on sterility and quality of work performed. Plus, innovations have appeared - restorations using modern materials, whose quality and perfection are steadily growing - which was not the case before. All this requires a high degree of preparation, which is why the rubber dam in dentistry has again gained popularity.

Indications and scope of application of rubber dam

In what areas of dental services is rubber dam installation used:

Endodontics: This branch involves treating the root canals of a tooth. And here it is very important not only to maintain perfect sterility, but also to prevent medicinal compounds from getting into the surrounding mucous membrane of the patient, so as not to cause an allergic reaction. It is also important to protect the area from liquids, i.e. saliva,

light fillings and artistic restorations: for high-quality adhesion of the composite and photopolymer to the walls of the tooth, their adhesion, the condition of the absence of moisture, foreign liquid, saliva must be observed, which ensures the device,
enamel whitening: the purpose of the rubber dam in this case is to protect the mucous membrane from the temperature effects of lamps, chemical bleaches,
fissure sealing,
splinting of teeth.

Pros for dentists

Using a rubber dam makes the dentist's job much easier as it provides good visibility and access even in hard-to-reach areas of the mouth. Other benefits are as follows:

There is no need to be distracted by auxiliary manipulations in the form of removing liquid or replacing cotton swabs, since the area is reliably protected from blood, saliva and other liquids;
The risk of infection and contamination of the working area with pathogenic organisms is eliminated, therefore risks such as relapse of caries or infection during dental canal treatment are practically reduced to zero;
Improving the quality of prosthetics and installation of fillings, their durability by eliminating the entry of biological fluids into the working area, which reduce adhesion.

Benefits of use for the doctor and patient

The use of a rubber dam in dentistry brings great benefits to both the doctor and the patient. Let's look at which one.

For the doctor: the ability to concentrate on work, convenient access to the desired tooth, improved visibility of the working field, dryness, cleanliness, sterility. The doctor can also easily monitor the condition of the tooth and the mucous membrane around it, stopping bleeding in time and carrying out disinfection. He spends his time rationally and can do without additional devices - a saliva ejector, cotton sponges.

For the patient: applying Optidam allows him to feel protected and not worry about the doctor injuring the lips, adjacent teeth, gums, mucous membranes, and the inside of the cheeks. A person can easily swallow saliva, because it will not harm the treatment process, and besides, medications, instrument fragments, and foreign impurities will not get into it. You also won’t have to spit or rinse your mouth often. Muscles and joints get less tired, because... treatment time is reduced. All this creates a feeling of some comfort.

Benefits for patients

The application of a rubber dam has many advantages for the patient, as it provides maximum comfort during treatment. Patient:

has the ability to make swallowing movements;
does not strain to constantly keep the mouth open;

does not experience discomfort due to dryness of the oral mucosa;
does not suffer from a gag reflex due to the insertion of cotton rolls;
practically does not feel the movements and actions of the doctor.

Patient comfort during treatment is very important, but the efficiency and quality of the procedures performed is equally important... and rubber dam allows you to increase them because:

Dryness in the working area allows you to achieve higher quality and durable restoration;
The oral cavity and throat will be reliably protected from contact with medications or tooth particles;
Eliminating the risk of dental preparations getting on the mucous membrane reduces the risk of developing an allergic reaction to zero.

Thanks to the rubber dam, all dental procedures are carried out noticeably faster, which also causes relief for many patients.

Purposes of application

Working with a rubber dam in dentistry is the key to protection against cross-infections and the confidence that the inflammatory process from a tooth during its treatment will not spread to neighboring ones. In addition, the installed filling or restoration will last much longer than it would have without the use of latex protection. After all, this ensures the dryness of the working space, and if saliva and breath vapors get inside, the adhesion of the filling material would be much less, and the treatment would be more effective.

It turns out that the main goal is to improve the level of quality of service, save in the long term, and be able to maintain the health of the oral cavity, teeth and gums.

Disadvantages and contraindications

The application of a rubber dam in dentistry is contraindicated for people with nasal breathing problems, because If isolation is applied to the mouth, such a patient will have difficulty breathing. They are not suitable for people prone to epileptic seizures, with Alzheimer's disease, or with allergic reactions to latex, rubber, or talcum powder.

As for the disadvantages of use, they also exist: an unprofessional doctor can spend quite a lot of time installing the device, and it can touch and injure the interdental papillae. This procedure cannot be done without an assistant or assistant. It is best to install a latex napkin in four hands. Also, the doctor may have difficulty selecting the shade of the tooth to be restored with direct restorations, because the rest of the dentition in this case is hidden under the cloth.

Well, and most importantly, this, although slightly, increases the total cost of treatment. But as studies show, 99 patients out of 100 patients would agree to the use of such measures even taking into account the increase in price - but doctors do not always offer it, and patients do not know about this.

Rubberdam. New quality standard?

Rubber dam in dentistry.

For many patients, the word rubber dam or rubber dam (synonyms) is new. What kind of device is this and why does the dentist use it? This is what today's article is about.

It’s no secret that dentistry has taken a noticeable “step forward” over the past few years. New technologies are replacing old ones, new companies are entering the market, equipment is being improved, materials are becoming more aesthetically pleasing and durable. There is a lot of money in dentistry (despite the crisis), so progress is inevitable and that’s great. On the one side. On the other hand, such a rapid change of generations of “equipment” requires the doctor to keep his finger on the pulse all the time, monitor the latest events, trends, and know how to apply these innovations in his practice in order to make it better . And do no harm.

Composite materials (composite “ light fillings ”) appeared in our country in the early 90s, if I’m not mistaken, and the use of composites began to gradually become widespread. Why did it happen so?

Before composites, teeth were filled with cements (phosphate, glass ionomer, etc.) or amalgam . These are good materials that have proven themselves, but cements and amalgam had a number of disadvantages, which subsequently led to the transition of most dentists to composite materials. It was difficult or impossible to model anatomy with cements; some of them caused toxic and thermal effects on tooth tissue during “hardening”; it was necessary to make some kind of insulating and “therapeutic” “gaskets”. Amalgam was also not completely biocompatible and easy to use (not to mention aesthetics). In addition to all this, the materials of the “past generation” required classical preparation; usually, for this, the doctor had to excise not only caries, but also healthy tissue in order to create retention points to hold such a filling. All undercuts (overhanging edges) were also ordered to be eliminated - otherwise there was a high risk of fracture.

Why are dentists happy to switch to “light fillings”? Firstly, of course, aesthetics . Nobody wants a metal filling, everyone wants a “white” one :) Secondly, compared to amalgam and cements, it was much easier to work with a composite. There is no need to mix or knead anything, the consistency of the composite made it possible to model it as much as you wanted, and then “illuminate” it with a lamp and the filling is ready! You don’t need to wait 2 hours to eat, the filling is beautiful, you don’t need a second visit for polishing, as with amalgam. All in all, a fairy tale.

But not everything turned out to be so simple. In addition to the composite itself, this technique of filling (restoring) teeth also uses an adhesive system . Her role was greatly underestimated by dentists, because... this has never been done before. In simple terms, the adhesive system is the “glue” that “sticks” the composite filling to the surface of the tooth tissue. This “glue” has a very complex chemistry (and over the years it becomes more and more complex) and the process of “gluing” the filling to the tooth is influenced by many factors. And one of the main factors is the cleanliness of the working area. That is, the absence of any “polluting” factors (blood, saliva, food plaque, etc.), including moisture. In order for the “seal” to “stick”, it must not only be clean, but also dry . Otherwise, the fillings “fall out”, “darken”, teeth hurt after treatment, thin walls break, etc. With proper adhesive restoration techniques , the tooth does not need to be over-prepared to create “retention points” and “additional sites” to “hold” the filling in place. This is a big advantage of composite materials, coupled with their biocompatibility and aesthetics. But often doctors “ don’t believe ” in adhesion (gluing) and prepare teeth “the old fashioned way,” as for cement or amalgam fillings. But that's half the trouble . If the conditions for carrying out the adhesive restoration technique are violated, the composite often behaves worse than cements and amalgam, which leads to complications even faster than in the case of using “old materials”. Pain after treatment, “falling out” fillings, wall fractures, secondary caries - this is most often the result of a violation of the technique of using the composite and the adhesive system. After the emergence of many complications, many doctors even became skeptical about composite restorations.

Great introduction. But without it, you would not be able to fully appreciate the significance of such a simple, but at the same time irreplaceable device as a rubber dam.

Rubberdam (eng. rubber - rubber, dam - barrier) is a system for isolating the working field in dentistry. Rubber dams are latex scarves that are fixed to the teeth with special metal clamps, “ clamps .” Oddly enough, rubber dam is not a newfangled “gadget” in the dental market. The technology is quite old and is already almost 150 years old ! This system was invented by the American dentist Sanford Christie Barnum in 1864. Why are we returning to this technology now? And why was she “forgotten”? The answer lies in my voluminous introduction. The reason is a change in technology . Rubberdam, which appeared on the market a century and a half ago, was very popular among dentists, but its popularity gradually faded away, because... The rubber dam had an indirect effect on the outcome of tooth filling, and required effort, time and financial costs for installation. Therefore, the rubber dam was used by a small number of doctors (in general, as it is now, unfortunately) and only for endodontic treatment. Now this isolation technique has again become in demand with the advent of adhesive technology for dental restoration and adhesive fixation of ceramic restorations, because adhesion is more demanding on the cleanliness of the working field.

In addition to ensuring absolute dryness of the working field, the rubber dam also prevents contamination (infection) of tooth tissues by oral microorganisms, which is of no small importance in root canal treatment. If you go for an X-ray of a tooth during treatment (with instruments or to check the filling of canals) without a rubber dam , saliva inevitably gets into the tooth and root canals, and with it, possibly, food plaque, which contains tons of microorganisms. This does not always lead to negative consequences, because... our body is a perfect system that is quite difficult to damage irreparably, but in combination with other factors, this can lead to chronic inflammation, destruction of bone tissue and ultimately even tooth loss . Cleanliness is the key to health. This also applies to root canals, oddly enough :)

not all agree that the use of rubber dam in endodontics is justified , but far fewer dentists agree in the treatment of caries They are more willing to believe in miraculous “healing pads” (which, I am sure, are not necessary) than in the advisability of isolation. But in my opinion, the use of rubber dam in the treatment of caries is more than justified , because dentin has a “porous” structure, and can also be easily infected by microorganisms, and this is an important factor when the cavity in the tooth comes quite close to the pulp chamber (deep caries, so-called).

All of the above applies to the treatment of children . But rubber dams in pediatric dentistry are the exception rather than the rule, unfortunately. It’s not customary for us to bother with primary teeth, and if a child has already erupted permanent teeth and they have caries, then at the “children’s appointment” there is usually no time for a rubber dam\it’s not necessary\I don’t know how/the child can’t handle it, etc. d. Hence the problems with teeth and bite at the age of 18-25 years, because most often the chewing teeth (first molars, “6s”), which erupt first, are affected, and these are the “keys of occlusion,” the most important teeth for full chewing. They are the first to be removed at a young age, most often.

Fortunately, more and more doctors (especially young ones) are beginning to use the rubber dam system to isolate teeth. This undoubtedly improves the culture and efficiency of our treatment. Rubber dam is a simple and affordable tool that every specialist involved in the treatment and reconstruction of teeth must own. It is not surprising that the rubber dam is accepted as a quality standard in the world's recognized dental communities. Rubber dam is not only a necessary standard for daily practice and improves the quality of treatment, but also comfort for both the doctor and the patient. Many doctors who do not use rubber dams say that it is “inconvenient” for their patients. But my daily practice (as well as research by scientists) shows the opposite: 99 patients out of 100 are absolutely not against a rubber dam, moreover, many even feel more comfortable with it.

The benefits of using a rubber dam are simple and clear. Why then do most doctors not use it in their daily practice at all, or use it on major holidays? The answer is quite simple: laziness and unwillingness to work better today than yesterday. Think about this when choosing your doctor and your child's doctor.

I hope in this article I was able to clearly talk about the “new old technology” called rubber dam, what it is needed for and when it is used. Thank you for your attention! Health to you and your teeth! :)

Types and properties of rubber dams

a classic of the genre: the classic dental rubber dam is made of rubber, which comes in different thicknesses and densities. The most popular option is the average value up to 0.23 millimeters; they are universal for any medical manipulation. Thick and extra-thick are mainly used for gum retraction - their density ranges from 0.29 to 0.38 millimeters. Also, sometimes individual optids are made on special orders when certain conditions must be met,

liquid rubber dam: it is based on a helium component, which, when applied, spreads evenly and polymerizes under the influence of light, hardens in the interdental spaces and on the gums. It is lightweight and easy to use. The main scope of application is whitening, removal of dental plaque and calculus during professional hygiene, an additional measure of protection in combination with a rubber dam during endodontic treatment of canals.

The color of the device also matters:

light shades: for example, light beige is suitable for treating and filling tooth canals. The material in this shade turns out to be almost transparent, which makes it possible to perform high-quality tooth restoration and determine its exact position, direction, and shape. Blue, pink, marble colors of rubber dam can also be used for these purposes - but they are used less often,
dark shades: green, gray, blue are used in restorations and allow you to determine the color, shape, and condition of adjacent elements of the dentition to select the desired shade.

Cofferdam can also be liquid

Liquid rubber dam is a light-curing gel-like material.

If you have had in-office teeth whitening, you have come across the use of a “liquid rubber dam”, although you may not have known that this is also a rubber dam. It is used to isolate the gums from the whitening gel.

Also, liquid rubber dam can be used for additional sealing after applying a traditional rubber dam.

We are glad that you learned new and useful information from our article, and if you need dental care, you can always count on the highly qualified doctors of Nord Dental clinics.

What tools does a doctor need to fix the rubber dam?

The installation of a rubber dam in dentistry should be carried out by a specialist using special auxiliary tools: a stencil or template (marker) to accurately determine the location of the tooth and select the place where the hole needs to be made. The doctor will also need a punch - this is a tool that will help make a cut on the latex sheet. The doctor must also have special fastening elements, fixing the rubber sheet: frame, staples and clamps (they differ depending on which tooth should be treated - there are types for upper and lower molars, premolars, central teeth and roots) clamps, floss and dental floss.

How does a doctor install a rubber dam?

There is absolutely no need to be afraid of the procedure. There are even several rubber dam techniques that a doctor can use depending on the situation.

"Wings". This option involves the use of a frame and a clamp; it is designed to work with molars and premolars.
Work in tandem with an assistant. In this embodiment, the doctor cannot do all the work himself; he needs the help of a person who will hold the insulating sheet on the frame. The doctor himself will fasten the clamps. Ideal for working with any teeth.
The work begins with installing a clamp on the tooth, and only then the latex scarf and frame are applied.
Arc method. Used when it is necessary to treat the lower teeth. It can be quite sensitive, so your doctor will administer anesthesia before using it.

While the complexities of installing the curtain and its nuances can only be understood by a professional, the process of removing the protective material is very easy and simple: when working with one tooth, after removing the clamp, the latex is easily removed. When treating several elements of the dentition, it is removed using special scissors.
