Forfenan in dentistry for reliable and comfortable root canal treatment

1000

A root canal is an anatomical cavity inside a tooth that contains the pulp (nervous tissue with blood and lymphatic vessels).

If for a number of reasons the dentist has removed the pulp, the remaining hollow canals must be filled.

In dental practice, several modifications of materials are used to seal them. The group of the most popular forms includes Forfenan.

Purpose and composition

Forfenan is a set of components for the preparation of a sealing paste, which is subsequently used to fill the dental canals.

The manipulation is carried out to isolate the pulpless part of the tooth from the periodontium (obturation), as well as for antiseptic treatment, filling difficult or infected root canals.

The paste is produced by SEPTODONT in France. Used to seal the canals of milk and permanent elements, i.e. applicable:

in the treatment of pulpitis of temporary units with devital amputation of the root pulp;
when filling permanent dental elements affected by caries.

Important! It is not recommended for the treatment of anterior teeth, since the coronal part of the pulpless unit may change color. It is problematic to neutralize such an effect, and you will have to install veneers or lumineers.

Forfenan for pregnant women

When treating teeth for pregnant mothers, you should be more careful. The product contains a very toxic component formaldehyde. It can cause harm if it is swallowed, gets on the surface of the skin, or gets inside the mucous membrane of the expectant mother. The negative impact is the possibility of burns. To prevent possible consequences, the tooth should be well isolated from neighboring tissues. To do this, dentists use a rubber dam.

The dentist should wear protective gloves before beginning work. If the substance comes into contact with the eyes, skin, or mucous membranes, they should be immediately rinsed with special care with water. Before starting dental treatment, the child’s mother should consider whether it should be started with the use of preparations containing formaldehyde. All the negative consequences of getting even small doses inside or on the outside of her body can affect the health, development of her fetus and the painless course of pregnancy.

Characteristics

Forfenan has established itself as a convenient and easy-to-use material that allows three actions to be carried out simultaneously in just one procedure:

Carry out accelerated antiseptic treatment.
Introduce a long-acting antiseptic.
Seal the channels hermetically.

When mixing the components included in the Forfenan kit, the resulting paste hardens within 24 hours. The basis of the mass is formed by an antiseptic mixture and red resin.

During polymerization, the temperature of the material rises, and a certain volume of gaseous formaldehyde is released from it, penetrating into the dentinal canals . This substance converts the albumins present in the components into insoluble antiseptic mixtures.

Material properties

If you mix the powder and both solutions that are included in the kit, it becomes possible for the radiopaque paste to harden within 24 hours. The basis of the resulting material is antiseptic paste and resin.

During polymerization, the material heats up and releases a certain amount of formaldehyde gas, which penetrates into the dentinal tubules. Formaldehyde gas converts the albumins present here into antiseptic mixtures.

As a result, Forfenan makes it possible to implement three actions at once during one procedure:

accelerated antiseptic treatment of dentinal canals;
introduction of long-term antiseptic material;
durable filling of root canals.

Such a filling also has other characteristics: the material closely fills the canal, it is radiopaque, does not allow shrinkage, and there is a risk of staining the tooth crown.

In liquid form, Forphenan is produced as two separate solutions and this makes it possible to vary the degree of exposure and its duration in accordance with the amount of each solution used. If the amount of medicinal solution is increased, the process of releasing the gaseous antiseptic will be more intense. This promotes deeper sterilization.

This product, like phenoplasts, should not be used for filling anterior teeth due to the coloring effect. Neutralizing such a defect will be quite problematic (masking with lumineers or veneers). In general, Forfenan is considered a useful adjunct for all types of routine root canal fillings.

Advantages

Forphenan differs from analogue materials in the following advantages:

Convenient to use , i.e. it does not depend on the level of moisture during filling and hardening, is characterized by a high plasticity index, does not stick to instruments when working, and retains its primary properties during long-term storage.
It is well introduced into the canals and fills them tightly - it has a good fit to the canal walls and chemical adaptation to the tissues, fills their entire volume without leaving cavities.
It is resistant to chemical influences and has a minimal degree of solubility , therefore, it is not destroyed by dentinal fluid or saliva.
Keeps the volume constant , which means it does not shrink.
It is radiopaque, i.e. there are substances (in this case it is barium), thanks to which it is possible to monitor the condition of the treated tooth and the filling placed using X-rays.
It has a pronounced disinfectant effect - it blocks the activity of pathogenic microflora and prevents its further spread.
Biocompatible - does not harm the mucous membrane, dental tissues and the body. There are no toxic components in the composition, the drug is safe for health workers and patients.

Thanks to these advantages, the material is an important addition when performing any type of root canal filling.

Kneading technique

To properly prepare the paste for closing canals from the materials included in the kit, you need to perform all the steps in the following sequence:

Pour 1 powder dispenser onto a special glass for mixing.
Add 1 drop of each solution to it.
Mix well.

If it is necessary to obtain a less durable paste at the output (for example, when repeated passage of the channels is assumed), then 2 drops of the medicinal solution and 1 drop of liquid for hardening must be added to the same portion of the powder.

Instructions for use

Stages of the treatment process:

One of the traditional ways to open a tooth from the inside is to carefully remove the remaining pulp. Perform medicinal and mechanical treatment of the tubules.
Dry thoroughly.
In the process of preparing the filling material, use a special mixing tool to mix one dispensing spoon with a drop of each solution. When a less strong mixture is required, for example, if the tubules are to be re-passed, then you need to use one measuring spoon of powder with two drops of medicinal liquid and one drop of hardening solution.
Seal the canal using the material prepared in this way. It is applied in portions with a canal filler or a root needle.

Application Guide

The treatment process for sealing root canals with Forfenan is carried out in the following order:

The dentist examines the oral cavity and makes a conclusion about the condition of the problem tooth. If necessary, the patient is sent for an x-ray to determine the number, location and condition of the root canals.
Examination of an x-ray.
Conducting topical anesthesia. Before applying a local anesthetic, the mucous membrane is dried. As soon as the anesthetic has shown its full effect, it is washed off with a stream of water.
Injection of anesthetic. Transcortical anesthesia is usually performed, during which the lips, palate and tongue do not become numb, but the sensitivity of the area of 4 teeth is lost (2 elements before and 2 elements after the injection site of the anesthetic).
Full access to the canals is created for their treatment. Burs are used to open the pulp chamber or a special cutter is used to prevent overheating of the interroot zone.
A rubber dam (latex curtain) is applied.
The pulp chamber is opened. Infected remains are removed from it.
Instrumental and then medicinal treatment of the canals is carried out.
Drying.
Filling the canals along their entire length with Forfenan paste. The material is introduced in portions using a root needle or channel filler.

At the end of the process, an x-ray is taken. The procedure is mandatory during endodontic treatment and is necessary to assess the quality of canal sealing.

Recommendations and precautions

When working and handling Forfenan material, precautions should be followed, since it contains a potent component - formaldehyde.

Vital amputation of the pulp of a young tooth

perform anesthesia
isolate the area using a rubber dam
open a cavity affected by bacteria
open the tooth with a bur with a rapid rate of rotation and having a supply of water into the oral cavity, to prevent overheating of the hard tissues of the tooth and the development of pulpitis
amputate the coronal pulp using an excavator and bur machine
rinse the cavity with distilled water and dry it well
periodically monitor bleeding and promptly eliminate it
mix forfenan
apply to the mouth of the canal

The drug is best suited for the treatment of pulp in the younger generation of preschool children.

Analogs

Dentists also use analogues of Forfenan in their work, which are not inferior in characteristics and properties to the material in question.

Resorcinol

White with a grayish or light yellow tint, crystalline powder. It has a specific faint odor and quickly dissolves in alcohol or water.

In light and air it changes its color to pink. It is a derivative of phenol, but is slightly inferior in antimicrobial activity.

Phenol is less toxic and less irritating to mucous membranes and tissues. It is characterized by keratoplastic (at low concentrations), keratolytic and cauterizing effects (at high concentrations).

In dentistry it is still applicable in the case of:

treatment and sealing of root canals for complicated caries;
cauterization of keratinized areas of the mucous membrane;
treatment of periodontal disease.

The demand for the material is explained by several facts:

ease of operation;
quickly achieving the required result;
low cost.

Important! Over time, a resorcinol-based filling turns the treated dental element pink.

Rezident

The material is used for antiseptic treatment and filling of root canals (including difficult to pass) with partial pulp expiration.

Set contains:

medicinal liquid containing formaldehyde;
hardening liquid;
powder based on resorcinol and radiopaque filler.

Additionally, it exhibits an anti-inflammatory effect.

Foredent

It is used for closing canals after depulpation, in periodontal treatment, as well as during third-party interventions (for example, during resection, dissection of alveolar walls, periapical curettage). Has a pronounced disinfectant effect.

The material is based on resorcinol-formaldehyde, known for its toxicity and negative effects. Therefore, when working with it, doctors strictly adhere to the dosage and observe safety precautions.

Forphenan analogs

When treating teeth and their diseases, dentists use medical substances with different compositions:

Viedent - contains an epoxy amino polymer. Produced in Russia by VladMiVa. It can be produced in two forms - two pastes (each element is four milliliters), or a powder mixture (twenty milligrams) and a liquid (ten milligrams). It is necessary for obturation of canals, if the patient has apical periodontitis or pulpitis. It can be used in conjunction with implants
Foredent is a preparation necessary for filling. Has the same purpose as Forfenan. Manufactured in the Czech Republic by Spofa Dental. Contains formaldehyde resin. It has three component forms - forty grams of powder, two bottles of twenty-five milliliters.
Rezodent is produced in our country by the VladMiVa company. Consists of resorcinol with the addition of resin. The drug has three component forms - a disinfectant solution with formaldehyde (five milliliters), a substance that promotes hardening with resorcinol and a catalyst (five milliliters), and a powder substance (ten grams). The purpose is to disinfect, install fillings on a complex canal, cavity with partially removed pulp. The time to work, after all the components are mixed, is half an hour. The substance may become completely solid in one full day.
Resorcinol - intended for installing fillings on the root canal. Manufactured in Russia by Omega Dent.

Reviews

The root canal sealing procedure differs from a simple tooth filling. There are special requirements for materials for this process.

Materials are constantly being improved or replaced with new ones. Despite the variety, dentists still use formalin-based products in their work, one of which is Forfenan.
