All the most important information about the purpose and use of the drug Kaustinerv in dentistry

1195

Devitalization in dentistry is the destruction (killing) of the pulp for the purpose of its subsequent painless removal.

The procedure is carried out using devitalization drugs that kill the nerve bundle of the pulp and cause the death of its tissue.

One of the drugs popular among dentists is Kaustinerv, which will be discussed further.

Indications and contraindications

Killing the pulp using devitalization pastes is used in cases where it is impossible to use injection or application methods of local anesthesia.

The following reasons may lead to such situations:

1. hypersensitivity of the patient's body to anesthetics, in particular to lidocaine;
2. insurmountable fear of the patient (usually children) to injections;
3. the presence of severe systemic diseases;
4. failures (insufficient pain relief) of the injection or application method.

General information

Devitalization in the dental field is the process of killing the pulp for its further removal without pain. The process is possible with the use of devitalization agents, which can kill the nerve processes of the pulp and cause the death of its tissues.

What does a tooth look like?

The surface of a healthy tooth is covered with white enamel, underneath is dentin. The inside of the tooth is made up of pulp with small blood vessels and nerves.

The number of large nerves directly depends on the structure of the root and the number of its processes. And the bundle of nerves in the pulp is formed by compact nerve fibers.

When the crown is destroyed down to the pulp, increased pain begins to appear.

Why is removal necessary?

It is possible to exclude nerve removal if therapy begins at the primary stage of dentin destruction. Pulpitis, which has passed into the periodontium, is a symbol of the transformation of the disease. Then the elimination of the nerve or pulp cannot be avoided.

Surgery is necessary when a tooth is deformed. Defragmentation is possible from caries or physical trauma.

Symptoms of inevitable depulpation:

- aching soreness that occurs for no reason and persists for a long time. Has no tendency to complacency.

- episodic pain. The reasons are a change in the level of humidity in the room, from cold or hot products, from eating a large amount of sweets. After eliminating the source of irritation, pain is still present.

- an unnatural dental arrangement determined from an anatomical point of view.

- inflammatory process in the pulp or the onset of periodontitis.

- mechanical trauma with damage to dentin.

Instructions for use

Devitalization is performed in the following sequence.

1. A carious cavity is developed , and a recess is made at its bottom to place the paste at a minimum distance from the pulp.
2. A small ball (about the size of a pinhead) is made from the paste and carefully, without pressure, placed into the hole.
3. A temporary filling is placed on the tooth , and the patient is sent home. A repeat visit is scheduled after a few days, depending on the duration of action of the devitalization paste.
4. At the next visit, the temporary filling is opened and removed along with the devitalizing drug. Under the influence of arsenic or paraformaldehyde, the pulp becomes fibrous and can be removed easily and painlessly.

Sometimes, due to severe pain, it is not possible to get close to the pulp. In this case, devitalization is performed in two steps.

After the first application of the medicine, due to a decrease in the sensitivity of dentin, it becomes possible to get closer to the pulp.

Next, endodontic treatment of the tooth is carried out according to the standard scheme:

1. Access to the coronal cavity is created using burs , the affected tooth tissue is excised and removed.
2. The tooth cavity is opened and the contents of the pulp chamber are removed.
3. Root canals are treated. Mechanical treatment is combined with medication using antiseptic, degreasing and hydrating drugs.
4. Obturation (filling) of the root canals is carried out with cement or composite material.
5. Finally, the crown part of the tooth is formed , which, if necessary, can be covered with an artificial filling.

Drastic ways to kill the dental nerve

If rinses and lotions do not help, and the tooth does not allow you to live in peace, you can try to solve the problem in a more drastic way. There are quite a few myths about how to kill a nerve in a tooth at home. One of the most ridiculous is the use of gunpowder. First of all, where would he get a house from? And secondly, such amateur activity is fraught with sad consequences for the body. However, like putting arsenic in the hole of a tooth. This is a powerful poison that, even in tiny doses, can deprive a person of not only his nerve, but his life! It is important to understand that the pastes discussed above do not use arsenic itself in its pure form, but its salts in carefully adjusted proportions.

So how can you kill the nerve in a tooth if you can’t go to the dentist right now?

1. Vinegar essence. Unlike gunpowder and arsenic, it is much easier to get. The manipulation is simple: moisten a small cotton swab with acid and place it in the hole of the tooth. You must first thoroughly disinfect your hands so as not to aggravate the situation by adding pathogenic microbes, and act carefully, as there is a high risk of burning your gums.
2. Alcohol. If rinsing with alcohol tinctures does not help, you need to wet a piece of cotton wool with alcohol and place it at the epicenter of the pain, preferably directly into the carious hole.
3. Zinc. Of course, it may not be at home in its pure form. But it is easy to obtain from ordinary printing ink. To do this, you can take any sheet of newspaper, but it is better if there are large black drawings on it, crumple it on a plate and burn it. Then, using a cotton swab moistened with your own saliva, quickly collect the ashes and place them in the tooth. The whole thing can be covered with another clean swab on top. Aldehydes and zinc contained in the ashes will kill the nerve. To prevent the procedure from being so painful, 15-20 minutes before, you can take a Ketanov tablet or another strong painkiller. The most effective medications for toothache are baralgin, novalgin, analgin, and pentalgin.

Whatever method of self-help you practice, the main thing to remember is that you still cannot do without the help of a dentist. Even if you managed to kill the nerve in the tooth at home, no later than two weeks later, you will still have to sit in the doctor’s chair so that he removes the dead tissue, cleans and seals the canals. Otherwise, a protracted inflammatory process cannot be avoided.

Dosage and precautions

When using all devitalization pastes, the same dosage is used - a tiny ball of paste the size of a pinhead (about 1 mm in diameter). The maximum permissible dose is 10 mg.

Since these are highly toxic drugs, the following precautions must be observed:

1. It is necessary to prevent accidental swallowing of the paste.
2. For a temporary filling, use cement of a weak consistency so that it can be opened without excessive force, which could cause the release of paraformaldehyde or arsenic.
3. The temporary filling must be absolutely airtight. If arsenic or paraform comes into contact with the mucous membrane of the gum or cheek, irritation and necrosis may occur. If a leak does occur, the affected area should be rinsed quickly with water.
4. The paste should not be left in the tooth for more than 7 days.
5. The medicine ball should be placed in the place prepared for it without strong pressure.

Important! Devitalization drugs contain substances that can give a positive reaction in a doping test.

Contraindications for devitalization are:

1. allergy to the ingredients of the devitalizing paste (most often the culprit is lidocaine);
2. age up to 30 months;
3. glaucoma;
4. anuria.

General presentation and purpose

Kaustinerv paste is produced by the French pharmaceutical company in three varieties:

• Forte. This product contains phenol and lidocaine and is used to remove pulp if it is necessary to use arsenic-free formulations.
• Arsenical . This type contains arsenic; the paste is used for devitalization if there are no contraindications for the content of this component.
• Rapid. This is an arsenic variety with menthol, ephedrine and lidocaine.

The paste has an analgesic effect, is used for rapid extirpation of tooth pulp and promotes an antiseptic effect.

Storage conditions

Kaustinerv devitalizing pastes can be stored for up to six months at a temperature not exceeding 25 °C. The material in opened cans retains its performance properties for a year, provided the lid is tightly closed.

Additional conditions for use and storage of pastes are contained in the instructions.

Composition and properties

The composition includes the following components:

• Lidocaine – up to 37%.
• Arsenic (only in two varieties - Rapid and Arsenical).
• Paraformaldehyde – up to 46%.
• Phenol.

The presence of paraformaldehyde in the composition promotes the coagulation of albumin, and lidocaine serves as the main anesthetic component and acts as a local anesthesia.

The impact of the paste leads to softening of the pulp and increased fibrousness, due to which rapid removal occurs.

Analogues and prices

The following preparations can be used as a replacement for Caustinerf pastes:

1. Depulpin. Contains paraformaldehyde. When used, side effects are possible in the form of pain, which gradually subside under the influence of the lidocaine contained in the paste. Release form – 3 g of paste placed in a syringe.
2. Devital. Arsenic-free preparation containing 30 percent paraform.
   The advantages of Devital include the absence of arsenic, the ability to be used for children, and the relatively short time for complete devitalization, usually 3-5 days. But sometimes canal cleaning and final filling can be done within 1-2 days. Available in 5 and 13 g in plastic and glass bottles.
3. Devit S. Contains paraformaldehyde, as well as auxiliary materials - lidocaine, creosote, paste former with filler. The average time of devitalization is 3-5 days.

Prices for pastes vary significantly, and depend primarily on the brand.

Approximate prices for devitalizing pastes are shown in the table.

Type of contact with the human body: constant contact with the internal environment of the body.

This product is sterile. For single use.

Conditions of use: in clinics, hospitals and other medical institutions by qualified medical personnel trained in the technique of injecting synovial fluid replacement agents.

Application area

The product is used for administration to replace synovial fluid in case of joint damage, to eliminate pain and improve joint mobility. The agent for replacing synovial fluid is used for osteoarthritis and other degenerative-dystrophic, traumatic and post-traumatic changes in the joints: knee, hip and other large joints, as well as as an aid in orthopedic surgery.

The medical device is used in traumatology, orthopedics, and sports medicine.

Product characteristics

The synovial fluid replacement product is a sterile, colorless and transparent viscous solution of highly purified sodium hyaluronate, obtained by biofermentation. The product contains sodium hyaluronate in a concentration of 10 mg/ml (RIPART® synovial fluid replacement agent), 15 mg/ml (RIPART® Forte synovial fluid replacement agent) and 20 mg/ml (RIPART® Long synovial fluid replacement agent), sodium dihydrogen phosphate, disodium hydrogen phosphate, sodium chloride 0.9% solution for infusion.

Sodium hyaluronate is the sodium salt of hyaluronic acid, a glycosaminoglycan formed by groups representing D-glucuronic acid and N-acetyl-D-glucosaminodisaccharide. It is widely present in the extracellular matrix in both animals and humans. The molecular weight of sodium hyaluronate used in the manufacture of the synovial fluid replacement agent must be at least 3 MDa.

Sodium hyaluronate belongs to a small group of substances that are the same for all living organisms. Sodium hyaluronate is a natural polysaccharide that is part of all tissues of the body, and sodium hyaluronate is found in especially high concentrations in synovial fluid and skin. The synovial fluid replacement agent consists of biosynthetically produced and purified sodium hyaluronate. Sodium hyaluronate in the body is a natural component of synovial fluid, which in joints serves as a lubricant for cartilage and ligaments, and is also an shock absorber. It is known that synovial fluid in affected joints has lower viscosity and elasticity than synovial fluid in healthy joints. Injecting sodium hyaluronate into a joint to restore viscosity and elasticity can reduce pain and restore joint mobility.

The composition of the synovial fluid replacement agent ensures the restoration of viscoelastic properties and the transition of the viscous properties of the solution into elastic (elastic) in the range of shear rates from 0.5 to 2.5 Hz, which corresponds to the range of movements from walking to running.

Basics of using the drug Kaustinerv for tooth pulp destruction

959

Devitalization in dentistry is the destruction (killing) of the pulp for the purpose of its subsequent painless removal.

The procedure is carried out using devitalization drugs that kill the nerve bundle of the pulp and cause the death of its tissue.

One of the drugs popular among dentists is Kaustinerv, which will be discussed further.

General idea and principle of operation

Kaustinerv is a line of devitalization pastes from the French company Septodont.

• Kaustinerv Fort. Contains paraformaldehyde as a devitalizing component.
• Kaustinerv Arsenical.
• Kaustinerv Rapide.

Rapid and Arsenical pastes contain arsenic anhydride (white arsenic).

Composition and properties of devitalization preparations Kaustinerv

As a rule, arsenous acid and paraformaldehyde are used as active substances in devitalization preparations.

The mechanism of action of arsenic anhydride on the pulp is to disrupt tissue respiration, leading to expansion and thrombosis of its blood vessels. The resulting hemorrhage and swelling lead to karyorrhexis and pulp death.

Paraformaldehyde performs the same function as arsenic - it kills the pulp. The principle of its action is the expansion of capillaries, stagnation of blood and mummification of the pulp, as a result of which it turns into a dry strand.

Paraformaldehyde has a milder effect than arsenic and does not cause severe periodontal irritation. However, high doses combined with prolonged action can also lead to necrosis of healthy tooth tissue.

Indications and contraindications

Killing the pulp using devitalization pastes is used in cases where it is impossible to use injection or application methods of local anesthesia.

The following reasons may lead to such situations:

1. hypersensitivity of the patient's body to anesthetics, in particular to lidocaine;
2. insurmountable fear of the patient (usually children) to injections;
3. the presence of severe systemic diseases;
4. failures (insufficient pain relief) of the injection or application method.

Instructions for use

Devitalization is performed in the following sequence.

1. A carious cavity is developed , and a recess is made at its bottom to place the paste at a minimum distance from the pulp.
2. A small ball (about the size of a pinhead) is made from the paste and carefully, without pressure, placed into the hole.
3. A temporary filling is placed on the tooth , and the patient is sent home. A repeat visit is scheduled after a few days, depending on the duration of action of the devitalization paste.
4. At the next visit, the temporary filling is opened and removed along with the devitalizing drug. Under the influence of arsenic or paraformaldehyde, the pulp becomes fibrous and can be removed easily and painlessly.

Sometimes, due to severe pain, it is not possible to get close to the pulp. In this case, devitalization is performed in two steps.

After the first application of the medicine, due to a decrease in the sensitivity of dentin, it becomes possible to get closer to the pulp.

Next, endodontic treatment of the tooth is carried out according to the standard scheme:

1. Access to the coronal cavity is created using burs , the affected tooth tissue is excised and removed.
2. The tooth cavity is opened and the contents of the pulp chamber are removed.
3. Root canals are treated. Mechanical treatment is combined with medication using antiseptic, degreasing and hydrating drugs.
4. Obturation (filling) of the root canals is carried out with cement or composite material.
5. Finally, the crown part of the tooth is formed , which, if necessary, can be covered with an artificial filling.

Dosage and precautions

When using all devitalization pastes, the same dosage is used - a tiny ball of paste the size of a pinhead (about 1 mm in diameter). The maximum permissible dose is 10 mg.

Since these are highly toxic drugs, the following precautions must be observed:

1. It is necessary to prevent accidental swallowing of the paste.
2. For a temporary filling, use cement of a weak consistency so that it can be opened without excessive force, which could cause the release of paraformaldehyde or arsenic.
3. The temporary filling must be absolutely airtight. If arsenic or paraform comes into contact with the mucous membrane of the gum or cheek, irritation and necrosis may occur. If a leak does occur, the affected area should be rinsed quickly with water.
4. The paste should not be left in the tooth for more than 7 days.
5. The medicine ball should be placed in the place prepared for it without strong pressure.

Important! Devitalization drugs contain substances that can give a positive reaction in a doping test.

Contraindications for devitalization are:

1. allergy to the ingredients of the devitalizing paste (most often the culprit is lidocaine);
2. age up to 30 months;
3. glaucoma;
4. anuria.

Storage conditions

Kaustinerv devitalizing pastes can be stored for up to six months at a temperature not exceeding 25 °C. The material in opened cans retains its performance properties for a year, provided the lid is tightly closed.

Additional conditions for use and storage of pastes are contained in the instructions.

Analogues and prices

The following preparations can be used as a replacement for Caustinerf pastes:

1. Depulpin. Contains paraformaldehyde. When used, side effects are possible in the form of pain, which gradually subside under the influence of the lidocaine contained in the paste. Release form – 3 g of paste placed in a syringe.
2. Devital. Arsenic-free preparation containing 30 percent paraform.
   The advantages of Devital include the absence of arsenic, the ability to be used for children, and the relatively short time for complete devitalization, usually 3-5 days. But sometimes canal cleaning and final filling can be done within 1-2 days. Available in 5 and 13 g in plastic and glass bottles.
3. Devit S. Contains paraformaldehyde, as well as auxiliary materials - lidocaine, creosote, paste former with filler. The average time of devitalization is 3-5 days.

Prices for pastes vary significantly, and depend primarily on the brand.

Approximate prices for devitalizing pastes are shown in the table.

Kaustinerv (Arsenic, Rapid, Forte): instructions for use

› Preparations › Materials

Kaustinerv is a dental devitalizing paste that is used for painless pulp removal. Manufacturer: Septodont (France).

Caystinerf is available in three types, each paste with an original composition:

1. Fort . Contains lidocaine, paraformaldehyde, phenol. Used for pulp extirpation without the use of arsenic.
2. Arsenical . Contains arsenic. Available in a plastic jar. Packaged in a cardboard box, instructions for use inside.
3. Rapide . Fast-acting arsenic paste. Contains arsenic, phenol, ephedrine, lidocaine, menthol.

All types of Kaustinerv are used for painless devitalization.

Instructions for use

Regardless of the composition of the drug used, preparation of the dental cavity is necessary before using the paste. The dentist removes decayed dentin, thereby getting closer to the pulp. The harder the dentin and the denser its layer, the slower the devitalization will occur.

The specialist applies a ball of the drug to the bottom of the cavity, this happens without pressure. The tooth is then sealed with a temporary filling. After 7-10 days, the cavity is opened (if arsenic Kaustinerv Rapid and Arsenic are used, then after 3 days). The temporary filling is removed along with the drug. During this time, the pulp becomes fibrous, making it easier to remove.

If direct contact with the pulp does not occur, treatment occurs in two stages. Initially, the root weakens, after which it will be necessary to use a small ball of the product again to completely remove it.

The dosage of each drug is the same: a ball no larger than one millimeter is used.

Allergic reactions and irritation are possible if there is sensitivity to the components of the material.

The paste should be used in solid form, the cavity should be well closed with a temporary filling. This will prevent evaporation of the active substance of the drug.

Athletes should use this product with caution as it may result in a positive drug test result. You should temporarily stop driving.

Cost and analogues

The approximate price of Kaustinerv paste is 2000-2500 rubles.

The storage temperature should not be higher than 25 degrees. After using the product, the lid closes tightly. Store in a dry and dark place until next use.

An open jar is good for a year. After this time, the use of the pharmacological agent is impossible.

Preparations similar in composition and properties that do not contain arsenic: Depulpin, Devital.
