Metapaste (Metapaste): composition, instructions for use, analogues

Dental material Metapaste is intended for temporary filling, ready for use without prior preparation.

With its help, the original dentin structure of the tooth is restored in the middle and deep stages of caries, as well as in some other cases.

The paste has a high pH of 12.5. Even after 10 days of the substance being in the inflamed area, this value does not fall below 12.

This material is characterized by a powerful bactericidal effect. Metapaste easily contacts pathogenic microflora, having a detrimental effect on it within five minutes after administration. After 48 hours, the inflamed area becomes completely sterile.

General overview

The drug is available in the form of a white paste, which has a medium consistency and is easily introduced into the cavity.
The substance is packaged in plastic syringes and is completely ready for use for filling. This product is produced in Korea.

When exposed, a bactericidal treatment is carried out, since the active components come into contact with the microflora of the oral cavity and completely destroy pathogenic microorganisms.

The effect begins 5 minutes after administration, and after 48 hours the treated cavity becomes completely sterile.

The kit, in addition to a syringe for 2.2 grams of the substance , includes plastic tips, each of which is intended for single use. Also included in the package is a ring with a rotating design , which allows you to adjust the direction of the tip when fixing it.

With the help of such a system, the introduction of paste into the tissues located around the tooth apex is made as quick and simple as possible; if necessary, the material can be removed.

One package allows you to fill up to 75 tooth canals with paste that require treatment for infection. The composition includes the following components:

  • Calcium hydroxide.
  • Barium sulfate.

Composition and equipment

The filling substance Metapaste contains calcium hydroxide and barium sulfate with high radiopacity. The drug is packaged as follows:

  • syringes with paste, the amount of which in each is 2.2 g;
  • special tips for single use;
  • a rotating ring that controls the direction of the tip.

Plastic syringes with cannulas are intended for one-time use; they repeat the shape of the canals one to one. They are fairly easy to inject into the tissue around the apex. If necessary, the paste can be easily removed. One package of the drug is enough to treat 75 canals susceptible to infection.

Therapeutic effect

Metapaste acts as a therapeutic pad during the treatment of deep caries.

With the help of this component, it is possible to completely disinfect all root canals, and in case of periodontitis, it is possible to form a protective barrier of hard tissue in the area of ​​resorption. Thus, the root canals are reliably and effectively isolated from infected tissue after closure of the lumen.

This treatment method always leads to positive histological results. Due to the high pH values, a lasting antibacterial effect is ensured.

The filling component reliably protects against the penetration of bacteria, isolates sensitive dental tissue, and prevents destruction.

Therapeutic effect

The drug serves as a kind of gasket in the treatment of caries that is at an advanced stage.

Using this substance, it is possible to disinfect dental root canals, in addition, it allows you to form a kind of barrier in the treatment of periodontitis


As a result of the influence of Metapaste, the root canals are completely protected from contact with infected tissues after filling, which ensures a positive treatment result.

The high pH level, which persists for several days, ensures a stable antimicrobial effect of the drug.

During treatment, the filling material protects sensitive areas and allows for the prevention of destruction of dentinal tissue , which is typical for caries, periodontitis and a number of other dental diseases.

The presented material for filling fillings has a considerable list of advantages and, when compared with other compositions, it is characteristic:

  • The penetration rate of X-rays is high, and insoluble silicone is used to prepare the paste itself. As a result, the composition can also be used to install permanent fillings.
  • Due to the fact that the composition is immediately filled with a syringe, it is easily inserted into the tooth root canal, and due to the disposable attachments, there is no risk of infection, which reduces or eliminates the need for repeated dental intervention.
  • It has an odontotropic and antibacterial effect - this allows you to achieve a lasting, positive therapeutic effect.
  • It does not disturb the pH level - its indicators correspond to a level of 12.5 units and due to this, the drug acts as a mild and effective local antibiotic, suppressing the growth and development of pathogenic microflora in the oral cavity.

In addition, the composition completely eliminates re-infection and inflammation of the canal, even in a patient with severe pathologies and complications.

Professional opinion

The point of view of practicing dental surgeons.

I really like working with Metapasta. The results from its use are always positive. Doctors in our clinic have been using it for a long time and actively use it in the treatment of pulpitis as a temporary filling material. It always lays down evenly, neatly, hardens quickly and efficiently. And most importantly, there are practically no contraindications.

Nikolay, dental surgeon

I often use this component and it has never let me down. Working with it is convenient, quick and easy. I can only advise all my dental colleagues to try it in their work. The canals are filled hermetically, and when the time comes, the paste can be easily removed. Moreover, even the patient himself can remove it without the slightest difficulty.

Paste properties

The manufacturer reports that Vitapex resorption approaches that of the root. The material is a soft, pre-mixed paste.

The paste is placed into the root and apical area with a plastic syringe and special tips. According to the manufacturer, the material is chemically and physically stable, has high radiopacity and excellent antibacterial and bacteriostatic properties.

Twenty-six professionals evaluated Vitapex in 200 clinical situations. This material received a rating of 92%.

The paste can be used as a temporary or permanent root canal filling material after pulpectomy.

In addition, Vitapex:

  • disinfects channels;
  • stimulates apexification;
  • neutralizes endotoxins;
  • stimulates the formation of hard tissues.

Calcium hydroxide is believed to have an antimicrobial effect and is easily absorbed if it gets beyond the apex of the tooth.

This is interesting: Treatment of gingivitis

The antimicrobial effect of calcium hydroxide is associated with its ionic dissociation into Ca2 + and OH- ions.

Vitapex/vitapex Preparation for filling root canals

The preparation for filling root canals Vitapex today is produced completely ready for use, representing a material packaged in a syringe used to inject the paste directly into the prepared canals. Due to this, the paste remains sterile during transportation and storage, providing a high level of convenience for the attending physician. Today, purchasing the drug Vitapex is the right and optimal solution, both for its independent use and in the case of combination with polypropylene pins such as Flex Point Neo, since the product is not capable of staining tooth tissue, promoting the resorption of granuloma during use.

The active components of Vitapex are intended to be used:

— silicone oil (22.4%), which, due to its hydrophobic properties, is capable of providing adequate isolation of root canals; — iodoform (40.4%), which has a powerful antibacterial effect; — calcium hydroxide (30.3%), providing osteoinductivity and a high level of radiopacity; — other components, the share of which is 6.9%.

After hardening, the drug can remain in a stable state for several years.

Vitapex provides effective antibacterial and bone-stimulating effects. And the presence of such a component as calcium hydroxide in its composition allows for the widespread use of Vitapex during dental treatment in children, filling the root canals of permanent teeth in which root formation has not yet completed. When filling baby teeth, the drug is absorbed at the same rate as resorption of the root of the filled tooth occurs. And after several years after treatment, this material shows no changes - both chemical and physical characteristics.

The main advantage of using Vitapex today is considered to be its powerful antibacterial effect, since after its use there is continuous bacteriostasis, which can ensure the cessation of growth of at least 80% of the population of anaerobic bacteria such as Streptococcus mutants and Lactobacillus casei, as well as the causative agent of purulent-inflammatory lesions Staphylococcus aureus.

The drug Vitapex does not require:

— calibration of the apical foramen, as well as the cone of the root canal; — endo-sealant, which provides three-dimensional obturation of the canal; — availability of expensive devices; - heating, as a result of which the possibility of getting a burn to the periapical tissues due to hot gutta-percha is completely excluded.

By purchasing this material, you will be able to save time, since the time savings with VITAPEX reaches 10 minutes when comparing the drug with lateral condensation or gutta-percha.

Indications and contraindications for use

In dentistry, Metapaste is used in a large number of cases, the main ones being the following:

  • with moderate caries, the original dentinal structure is restored;
  • in case of deep caries and pulpotomy, pulp covering is carried out;
  • for destructive periodontitis with subsequent apexification;
  • for fractures, perforation of dental roots;
  • to restore deformed periodontal lining;
  • formation of a form of secondary dentin in the form of a barrier of hard tissue;
  • temporary filling of infected canals.

In most cases, the use of the drug is well tolerated and there are no complaints from patients. But in some cases, when there is hypersensitivity to barium sulfate, the component is not recommended.

It is forbidden to use the paste after its expiration date.

Indications and restrictions

Dentists use the drug in a very large list of cases. The most common indications for use of Metapaste:

  • The middle stage of caries development , requiring restoration of the primary dentin of the affected teeth.
  • Advanced form of caries, pulpotomy.
  • Destructive periodontitis requiring apexification.
  • Fractures of tooth roots , the appearance of holes.
  • Restoration of the periodontal lining , which was deformed during mechanical influences.
  • Creation of a layer of secondary dentin , which is a hard type coating.
  • Installation of temporary fillings with closure of infected canals.

As a rule, the use of Metapaste is not accompanied by any difficulties, however, in case of individual intolerance or allergy to barium sulfate, it is better not to use this remedy.

Advantages and disadvantages

The advantages of the product include the following properties:

  • Excellent X-ray absorption performance.
  • Rapid manifestation of the antibacterial effect . Within 5 minutes the substances begin to act and kill harmful microorganisms.
  • Convenient release form , the paste is ready for application immediately, without any specific preparation.

"Metapex" in dentistry

"Metapex" is a filling material based on calcium hydroxide with iodoform. Used for filling root canals.

It is distinguished by its antibacterial effect, reliable adhesion to the bone tissues of the tooth, contrast in X-ray examination and ease of use. Supplied in closed syringes of 2.2 grams.

The mixture contains silicone oils, thanks to which it dissolves slowly.

Main advantages of the drug

"Metapex" has a long-lasting bactericidal effect, which is achieved due to pH 12.5. 48 hours after administration of the drug, up to 99% of microorganisms located in the root canal die.

The antibacterial component - iodoform - destroys Gram-positive pathogens, staphylococci, streptococci, fungi and viruses.

It eliminates the appearance of secondary inflammation even with complications in the form of cysts of various origins.

The paste-like consistency ensures convenient administration of the drug without prior mixing. The substance is packaged in a syringe with a sealed cap that protects Metapex from contact with air. The kit includes disposable cannulas for insertion.

The substance contains radiopaque components, due to which the sealed canals are visible in the corresponding study.

"Metapex" is safe for the soft tissues of the body, so it can be injected into leaky canals and during apexification.

You can purchase Metapex in the catalog of the Stommarket online store (follow the link).

Characteristics and scope of use of "Metapex"

"Metapex" can be used for permanent and temporary filling of root canals. However, practicing dentists recommend using it exclusively for temporary restorations. The drug itself is easy to remove and wash out, but over time its adhesion to bone tissue increases, so after prolonged (from 1 month) wearing it can be difficult to remove.

The drug is used for filling root canals with complications such as:

  • Pulpotomy;
  • Accidental opening of the pulp;
  • Leaks;
  • The need to create a barrier of dense tissue caused by ossification, perforation or resorption;
  • Unformed apex on baby teeth;
  • Apexification;
  • Infection, the appearance of microbial infiltrate.

The main indication for using Metapex as a permanent filling material is infection of the canal. Antimicrobial properties provide long-lasting antibiotic action.

The drug causes the formation of replacement dentin, and also stimulates the remineralization of tooth bone tissue when they are weakened. The odontotropic effect is due to the presence of calcium compounds in the composition.

Some clinical cases of using Metapex

"Metapex" is recommended for temporary filling of root canals. Although it can be used for permanent wear in some cases, it is not considered suitable for this purpose by dental practitioners. However, the composition based on calcium compounds and silicone oils ensures stability while in the root canal - it does not dissolve.

Thus, “Metapex” is best used as a means for temporary canal filling if antiseptic treatment of tooth tissue is necessary. The drug is also suitable for sealing in the treatment of various diseases. After positive dynamics appear, it is recommended to replace it with another silar.

For permanent and temporary root canal filling, Metapex is applied as follows:

  1. It is necessary to treat the root canal;
  2. Then dry it with paper points;
  3. Insert the tip of the syringe with the drug into the canal;
  4. Fill the channel;
  5. Remove excess with a cotton ball.

The cannula tips for the syringe are disposable. The set includes 20 pieces. The cannulas are equipped with a cap for hermetically sealed closure.

The drug cannot be stored in an open syringe, since when exposed to air it loses its antimicrobial properties and begins to harden.

The drug, like other silars, cannot be taken beyond the apex.

Instructions for use Metapaste

  • Once the root canal preparation is complete, clean and dry it.
  • Install the disposable tip onto the syringe, as well as the included ring for easy redirection of the tip.
  • Insert the tip into the root canal.
  • Fill the channel completely by pressing down on the syringe plunger while slowly withdrawing the tip.
  • Remove excess paste using a sterile cotton ball.
  • Remove the used tip, attach a new one and put the cap on it.


  1. Easy cleaning and removal
  2. Excellent antibacterial effect and radioopacity
  3. Ready-made paste in an easy-to-use syringe
  4. Easily penetrates the root canal, which prevents re-infection as a result of repeated manipulations
  5. Soluble in water

Precautionary measures

  • Do not enter past the apex.
  • Use only in dentistry.
  • Do not use in the treatment of patients with hypersensitivity to barium sulfate.
  • Avoid direct exposure to sunlight.
  • When the syringe is not in use, the cap must be on at all times.
  • Store in a cool dry place. (Temperature: 10-25°C)

Improper storage of Metapaste can cause the paste to dry out or separate.

Shelf life: two years from the date of manufacture.

Step-by-step instruction

The use of the product is permitted subject to the following sequence:

  • When a specialist prepares a tooth root canal, he rinses it and dries it. After this, the tip is put on the syringe with the medicine. You also need to put a ring on the latter in order to be able to change the angle of the tip.
  • The structure is inserted into the channel , the paste is injected by pressing on the syringe piston, carefully and gradually filling the cavity.
  • Excess paste is removed manually using a ball of medical cotton wool.
  • A temporary filling is placed on the tooth , the tip is removed from the syringe and a new one is installed if it is necessary to continue treatment of other canals. If therapy is carried out for one tooth, the syringe is closed with a standard cap.
  • Unsealing is performed by a doctor using endodontic devices using the classical technique.

Important! After use, the syringe must be closed if there is any residual product left in it. Contact with oxygen causes rapid hardening of the components, after which it will be undesirable to use the drug.

Precautionary measures

  • Do not enter past the apex.
  • Use only in dentistry.
  • Do not use in the treatment of patients with hypersensitivity to iodoform.
  • Avoid direct exposure to sunlight.
  • When the syringe is not in use, the cap must be on at all times.
  • Store in a cool dry place. (Temperature: 10-25°C)
  • Improper storage of Metapex may cause the paste to dry out or separate.

Expiration date: Two years from the date of manufacture.

special instructions

When using filling material, you should be careful, attentive and follow all precautions:

  • introduce the paste slowly and carefully, without going beyond the apex;
  • to be used exclusively in dental practice;
  • do not use for the treatment of patients with individual intolerance to individual components;
  • store the paste in a dark place, avoiding exposure to sunlight;
  • if there is no need for a syringe, then at this time it should be tightly closed with a cap to prevent the paste from drying out and maintaining its sterility;
  • The substance must be stored at a temperature of 10 to 25C.

Side effects and effectiveness

In most patients, Metapaste does not cause any side effects, therefore it has a wide range of applications, including in the treatment of pregnant and lactating women, children and adolescents.

The components included in the composition extremely rarely cause an allergic reaction; it usually manifests itself in barium sulfate.

Experts note that replacement of the substance in the root canal must be carried out on time, then complications do not occur.

Studies show that a year after treatment, the mucous membrane retains its elasticity and normal shade , and with mechanical impact there is no discomfort or pain.

X-ray examination determines that osteogenesis is more intense , and the inflammatory process almost stops.

Most often, side effects occur when the treatment method is violated:

  • Irritation of periodontal tissues when the paste gets outside the apex zone.
  • Itching, pain and redness upon contact with the skin, eyes and respiratory organs.
  • Hypersensitivity to individual components that make up the drug, which often manifests itself in the form of allergies.

Maximum security

No possible adverse reactions to the use of the substance have been identified. There are no complaints from patients.

If the paste in the canal is replaced in a timely manner, no complications are noted. Metapaste does not cause irritation or inflammation in the tissues surrounding the apex.

There were also no complaints 12 months after treatment. The mucous membrane had its characteristic color, was dense and did not produce a painful reaction when pressed. Radiographs showed that the focus of inflammation was noticeably reduced and osteogenesis was stimulated.

Purchase and analogues

You can purchase the Metapex filling composition in almost every dental store and online pharmacy, both the paste itself and its accessories, a syringe and disposable attachments. Prices and analogues of Metapex may vary. So the cost of the drug itself can vary from 500 to 1000 rubles. This is a fairly low price for a material of this class!

Among the direct analogues of the composition, the following can be distinguished:

  1. Silapex is a filling composition intended for filling tooth root canals, and contains calcium hydroxide. Stimulates the formation of hard tissues in the tooth structure, is well tolerated by patients and does not contain eugenol.
  2. Calasept is a radiopaque composition created on the basis of calcium hydroxide, used in dentistry for the placement of root canal fillings in the tooth and direct type of pulp coverage. It is used both for temporary and installation of permanent fillings, the formation of a protective coating of the pulp and as an insulating composition in the deep cavity of the tooth.

Analogs and price

The cost of Metapaste is 1100-1600 rubles, depending on the specific pharmacy and city. Spud and Calcetin as analogues .

These drugs are almost completely identical to this product, are produced in the same packaging, their price does not exceed 1500-1700 rubles.

In addition, the doctor can use Apexdent or Vitapex , which are enriched with iodoform and provide a more pronounced antibacterial effect when applied to the root canals.

The cost of the first drug varies between 220-270 rubles, and the second - 500-700 rubles, so you can choose a substance for installing temporary fillings not only by properties, but also by price.

Release form and composition

The kit includes a two-gram syringe with paste and twenty disposable tips. The initial trial kit contains one 0.5 gram syringe and three disposable tips.

  • 30.3% calcium hydroxide stimulates blast cells that promote apexogenesis, high pH neutralizes endotoxins produced by anaerobic bacteria;
  • 40.4% iodoform increases radiopacity;
  • 22.4% silicone oil provides complete coverage of the channel walls;
  • 6.9% - other ingredients.

Solubilized calcium hydroxide remains active in the root canal.
