Unique properties of Forfenan paste for use in endodontic dentistry

1001

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.

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.

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.

Forfenan (20g+10ml+10ml)

set phenol plastic resin (20g+10ml+10ml) Treatment of root canals before filling, canal filling

Composition Powder: Dexamethasone 0.20 g. Barium sulfate 49.80 g. Excipient 100.00 g. Medicinal liquid for treatment: Formalin 80.00 g. Excipient 100.00 g. Liquid for hardening: Resorcinol 25.00 g. Hydrochloric acid 13.00 g. Excipient 100.00g.

Properties As a result of mixing both liquids and powder, which are the components of FORPHENAN, it becomes possible to harden within approximately 24 hours a radiopaque paste, the structure of which is formed by a red resin and an antiseptic paste. During polymerization, the paste heats up and releases a certain amount of formaldehyde gas, which penetrates into the dentinal tubules, turning the albumins found here into insoluble and aseptic mixtures. Thus, FORFENAN makes it possible to carry out three actions at once in one operation: a) rapid antiseptic treatment of dentinal tubules; b) administration of a long-acting antiseptic substance; c) reliable filling of root canals. This filling also has other qualities: the paste densely fills the canal, is radiopaque, does not shrink, and has the possibility of staining the tooth crown. Liquid FORPHENAN is available in the form of two separate solutions, which allows you to vary the strength and duration in accordance with the amount of each liquid used. If you compare the amount of therapeutic liquid, the release of gaseous antiseptic will be more intense and will contribute to deeper sterilization of the dentinal tubules. Like phenoplatst, this drug should not be used for filling anterior teeth due to the staining effect of the paste. Forfenan is a necessary addition to all types of conventional root canal filling.

Indications Filling infected root canals in both permanent and temporary teeth.

Method of application a) Open the tooth cavity using one of the usual methods; completely remove remaining pulp; carry out mechanical and medicinal treatment of the canals. b) Dry thoroughly. c) When preparing a filling paste using a mixing device, mix one dose-spoonful of powder with one drop of each liquid. When it is necessary to obtain a mixture that is not so strong, for example, if repeated passage of channels is envisaged, it is necessary to use one measure of powder with one drop of hardening liquid and two drops of healing liquid. d) Seal the canal using the paste prepared in this way.

Packaging FORFENAN. Box with set: bottle 20 g min. powder with a dispensing spoon; bottle 10 ml min. medicinal liquid; bottle 10 ml min. hardening liquids; mixing device.

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.

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.

Forfenan - instructions for use

1. open the tooth cavity using one of the usual methods, completely remove the remaining pulp. Carry out mechanical and medicinal treatment of the canals
2. dry thoroughly;
3. When preparing a filling paste, use a mixing device to mix one dose-spoonful of powder with one drop of each liquid. When it is necessary to obtain a mixture that is not so strong, for example, if repeated passage of channels is envisaged, it is necessary to use one measure of powder with one drop of liquid for hardening and two drops of healing liquid;
4. fill the canal using the paste prepared in this way.

Recommendations and precautions

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

This substance is toxic and negatively affects the body if vapors are accidentally inhaled or come into contact with open skin and mucous membranes. At high concentrations, formaldehyde can also cause burns.

It is for this reason that when treating canals, it is necessary to isolate the problematic element from the surrounding tissues with a rubber dam.

Before starting work, you must wear gloves. If the material gets into your eyes or mucous membranes (skin), rinse thoroughly with water.

It is also necessary to take into account the possibility that the client may be allergic to the ingredients of Forfenan paste. Usually, the doctor finds out the likelihood of this fact before starting treatment.

From many dentists you can hear arguments about the inappropriateness of using formaldehyde-based products in practice. However, SEPTODONT guarantees that the material meets all international standards in terms of quality and safety criteria.

special instructions

It is necessary to take precautions when handling the medicinal solution, as it contains the potent substance formaldehyde.

This substance is very toxic and has a negative effect on the body if inhaled, swallowed, in contact with open skin, on mucous membranes, etc. Can cause a burn. Therefore, it is very important to isolate the tooth from surrounding tissues. To achieve this, dentists use traditional means such as rubber dams and rubber dams.

Before working with the material, be sure to wear gloves. In case of contact with skin, eyes or mucous membranes, they should be rinsed with copious amounts of water. To avoid negative health consequences, it is recommended to seek medical attention.

It is also necessary to take into account the likelihood that the patient has allergic reactions to the components. It is important to identify this before the procedure.

Experts from post-Soviet countries are actively arguing about the advisability of using formaldehyde products today. However, it is necessary to mention that the composition of the French drug Forfenan with a 100% guarantee meets the strict requirements in force within the European Union. The material is recognized as safe and certified.

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.

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.
