“Carpule” anesthesia in therapeutic dentistry: choice of drug, features of implementation (157) - Therapy

Thanks to the latest technologies in dentistry, people are gradually getting rid of the fears associated with visiting a doctor. During the treatment process, local anesthesia is often used, which previously was a very unpleasant procedure for some patients. During conventional anesthesia using a carpule syringe, the needle first penetrates the tissue, and then it moves deeper and the anesthetic is administered. All these factors can cause unpleasant and even painful sensations during anesthesia. In addition, after the procedure, loss of sensitivity of oral tissues persists for a long time.

The mechanism of anesthesia using the Single Tooth Anesthesia System

The STA apparatus itself consists of two main parts. This is a small unit in which a microprocessor is installed that controls the anesthesia procedure. As well as a sterile disposable tube with a special ergonomic tip with a needle. The needle itself is incredibly thin, which ensures the most delicate penetration into the mucous membrane of the oral tissues.

When the doctor makes the first touch with the tip to the gum , the device begins to analyze the density and resistance of the tissue and gradually release an anesthetic solution. As it moves into the tissues, the release of the solution continues in an optimal individual mode, taking into account the anatomical and physiological characteristics of the tissues of each patient.

As the needle penetrates deeper into the gum, the program continuously evaluates the parameters, changing the mode of drug administration . The computer constantly regulates the speed, degree of pressure and amount of administered medication. This is done to ensure that the painkiller travels to the nerve endings along the path of least resistance, without causing a feeling of fullness or burning and excessive pressure on the soft tissue.

evaluates the condition and resistance of tissues , which, in case of any deviations from the norm, gives an audible and visual signal to the doctor. For example, if the resistance and density of the tissues are increased or the needle tip is clogged, the device will signal and automatically stop supplying the anesthetic.

The STA device provides the dentist with all the necessary information in real time . Thanks to this, the specialist can adjust the correct position of the needle without causing pain to the patient. At the same time, the needle moves smoothly and evenly, making the necessary rotational movements to achieve an accurate, fast and most pronounced effect.

Today, patients have an alternative: the STA system.

Computer anesthesia is a local, imperceptible anesthesia using a device controlled by a computer, the so-called “single tooth anesthesia.” It is approved by the American Dental Association and recommended as the optimal method of pain relief.

This anesthesia is liked by those patients who are afraid of injections, but at the same time want to feel comfortable in the dentist's chair. This is especially important when treating children. When using STA, the child does not experience fear of a traditional syringe, and the anesthesia process itself occurs as delicately and effectively as possible. Thanks to this, the dentist can calmly carry out all the necessary manipulations and leave only positive impressions on the little patient after the appointment.

Reviews

Flaws

As for the negative aspects of carpule anesthesia, practically none have been identified.

A number of patients note the high cost of the drug, which makes it limited to the category of citizens with low material income.

However, this is a controversial drawback, since the complexity of manufacturing the product and high efficiency are associated with additional manufacturing costs. A quality product cannot be cheap.

Another disadvantage is the inability to modify the composition. A vasoconstrictor cannot be added to it, but in some clinical cases this is necessary.

Popular means

The most popular option for carpule anesthesia is the products of French manufacturers, which are effective and affordable:

Ultracaine is the most popular concentration for dental pain relief. The effect occurs after a couple of minutes and lasts for at least an hour;
Ubistezin - the duration of pain relief does not exceed half an hour, this time is sufficient in most clinical cases. Indications for use: children, pregnant women;
Scandonest – has a high concentration of adrenaline. Side effect is a long-term vasoconstrictor result. Prevents bleeding;
Septanest - has a mild effect. The sensitivity threshold remains extremely low for 15-20 minutes. Indicated for people prone to allergies, with severe pathologies and serious chronic diseases, when the use of stronger drugs is not recommended.

Reasons for the lack of pain relief

In some cases, the effect of the product may be minimal or absent altogether, that is, tissue sensitivity remains almost at the same level.

There are reasons for this. If we exclude damage to the packaging and a violation of the properties of the composition, the lack of pain relief is explained by the following factors:

fear of the upcoming procedure - fear blocks other reflexes, and anesthesia does not occur;
production of adrenaline - it is intensely produced in moments of panic and enters the nerve cells, neutralizing the effect of the drug.

To exclude such manifestations, experts recommend that patients prone to panic fear of the dentist take a sedative half an hour before the procedure.

Chronic alcohol dependence, as well as the body’s addiction to the drug, can have an inhibitory effect.

Injector contents

The use of the drug requires the dentist to know the composition of the anesthetic. This information is contained on the packaging; there is a detailed breakdown of the percentage of all its components.

Injector includes:

An anesthetic is a substance that reduces the pain sensitivity threshold in the injection area to a minimum. These compounds are classified under the category of amides and their derivatives. These are mainly Lidocaine, Prilocaine, Articaine;
vasoconstrictor – activates vasoconstrictive processes, which prolongs the relief of nerve endings and increases the effect of the drug.
In addition, the substance prevents premature leaching of the drug from the working area.
It has a serious limitation for use - the drug is prescribed with extreme caution to people with pathologies of the cardiovascular system, diabetes mellitus at any stage of the disease, and elderly patients. Vasoconstrictors include adrenaline, mesaton;
antioxidants are mainly sodium sulfites or bisulfites.
Their main function is to protect the vasoconstrictor from destructive processes that occur under the negative influence of an oxygen environment. They can provoke individual intolerance, including acute allergic reactions, since they contain sulfur fragments. Contraindicated for diseases affecting the lungs and bronchi;
preservatives – ensure the safety of the composition until it is opened;
EDTA – metal binder;
parabens are fragments that ensure absolute sterility of the capsule contents. This is especially important when transporting to regions with hot climates.

Thanks to this balanced composition, the anesthetic is reliably protected from the penetration of pathogenic microorganisms.

The main requirement related to the specific composition of the anesthetic is to make sure before using the medicine that the patient is not allergic to its derivatives.

Neglect of this rule is fraught with anaphylactic shock, which can cause irreparable harm to human health.

Advantages of computer anesthesia

The use of a special computerized STA system has the following advantages:

control of the pressure and rate of anesthetic delivery for maximum effective pain relief (the patient does not feel pressure or distension when the medicine is administered);
computer anesthesia can be performed in children, pregnant women and people suffering from arterial hypertension;
damage to ligaments and blood vessels is excluded (which can happen due to excessive stretching or too large a dose of the drug with traditional anesthesia);
in 9 out of 10 patients, the level of fear and stress decreases when using computer anesthesia (people do not see the syringe and do not experience anxiety, since the working part of the device resembles a fountain pen);
Only the area in which dental procedures will be performed is anesthetized;
Thanks to computerized control, the amount of anesthesia used can be reduced without compromising the effectiveness of the procedure.

Storage rules and periods

Any medicine needs proper storage. Capsules must be kept in a dark place. The optimal storage temperature is 23-25 degrees.

Failure to comply with basic conditions will shorten the shelf life of the composition, and improper transportation may compromise the structural integrity of the package.

Such drugs should not be used under any circumstances. Injectors should be stored in places inaccessible to children and pets.

Signs of loss of drug properties

You can understand that the medicinal effect of the drug has been neutralized and it has lost its main characteristics by a number of signs:

the integrity of the packaging is compromised - most often this is due to careless transportation;
An uncharacteristic sediment has appeared in the liquid or the shade of the composition has changed - this happens when the temperature regime is violated, causing overheating. The vasoconstrictor disintegrates and the agent changes its structural content;
the appearance of gas bubbles larger than 0.2 cm. This is a consequence of freezing;
the appearance of rust fragments on the outside of the ampoule.
