Foredent is a material based on resorcinol-formalin resin, used for permanent filling of tooth root canals. Available in the form of powder and liquid, which when mixed form a special paste with a disinfecting effect, from which permanent fillings are made. Sealer Foredent is the simplest and most affordable product, used everywhere in most clinics in the CIS.
Key features of the material
The substance is produced by a Czech company – Spofa Dental. The product is fully certified and safe for use according to all European standards. The main components of the drug are resorcinol and formaldehyde. These components are included in a set consisting of 40 grams of powder mixture and two containers with liquids of 25 grams each.
The dental product Foredent is a material that has long proven itself to be simple and easy to use. A filling preparation created on the basis of resorcinol-formaldehyde resin has a huge number of advantages when working:
- easy to process;
- remains unchanged in volume;
- fits well into the canal;
- has a strong disinfectant effect;
- radiopaque;
- guarantees reliable tightness of the sealed canal.
The paste hardens in about an hour. The filling mixture becomes completely hard within a week.
The manufacturer of the drug recommends storing Foredent in a cool, dark place at temperatures from +5 to +25C.
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.

Instructions: Foredent
The most important substance of the drug, resorcinol-formaldehyde resin, is a toxic substance that causes negative consequences if inhaled or in contact with open skin and mucous membranes. For safety reasons, the tooth to be filled must be completely isolated from neighboring tissues. To achieve this, dentists use rubber dam substances.
Installed rubber dam on a tooth
Work with Foredent substance only with gloves and in a well-ventilated area. If the drug gets on the skin or mucous membranes, it is necessary to treat the area with water as soon as possible.
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.
Restrictions and contraindications
Foredent tends to change color over time, so its use on the front teeth is undesirable. Pink-brown areas on the front incisors look extremely unsightly. Such a defect can only be eliminated using camouflage agents such as veneers and lumineers.
Resorcinol-formaldehyde material must be used extremely carefully, taking into account all the nuances. When toxic components get on various tissues, they have a harmful effect on them. Formaldehyde, which is part of Foredent, tends to permeate tissues and penetrate beyond the boundaries of the tooth, so it is necessary to carry out isolation very carefully.
Potent substances that enter the oral cavity and respiratory tract lead to negative consequences, so strict adherence to the marginal seal of the filling is required. Substances in Foredent may be allergens, so it is necessary to clarify whether the patient is allergic to the components of the drug. A person may experience a reaction to toxic substances if the paste gets beyond the apex.
The cavity is filled with Foredent only up to the apex.
Opinion about the drug
The use of resorcinol-formaldehyde substances in modern practice raises much debate about the safety and appropriateness of their use. Some dentists call this mixture very dangerous for the human body. The main materials used are highly toxic. Filling pastes have mutagenic properties and have a teratogenic effect. Formaldehyde has the ability to spread throughout the body and gradually poison it. Teeth filled with resorcinol-formaldehyde resins cannot support dentures.
For a very long time, dental canal fillings have been performed using resorcinol and formaldehyde. Over many years, the manufacturer has learned to make the safest drug, Foredent, that meets all standards. It is one of the most common dental materials in the world. All components and quality of the paste meet all European standards. Foredent is certified and recognized by leading dental clinics in the world.
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.
Price Foredent
The price of Foredent varies. On the Internet, the cost of one set, consisting of 40 grams of powder and two containers of liquid of 25 grams each, ranges from 339 rubles to 473 rubles. In Russia, the average price of filling material is 400 rubles. In Moscow pharmacies, the cost of Foredent can reach up to 600 rubles.
Analogs and price of material
The price of Foredent varies. In online pharmacies you can order one set (40 g of powder + 2 x 25 g of liquid) at a price of 309 rubles. In pharmacies the same packaging can be purchased from 325 rubles. up to 450 rub. In Moscow, the cost of the drug can reach 500 rubles.
There are many analogues:
- Rezodent (Belgorod) - paste for filling and antiseptic treatment of difficult-to-pass canals, consists of resorcinol-based powder and x-ray contrast filler;
- Forfenan (France) – a mixture for filling canals that are infected;
- Resorcinol is a formaldehyde paste produced in Russia (Omega).
There are other analogues that can compete with Foredent.
Analogues of Foredent
There are many analogues of Foredent on the market. The most common of them:
- Resorcinol is a Russian analogue based on formaldehyde components. Manufactured by Omega.
- Rezodent is a preparation with a disinfectant effect used for disinfection of root canals and fillings. The composition includes an x-ray contrast filler and resorcinol with special additives. Produced in Belgorod. Price from 130 rubles.
- Forfenan is a French analogue for filling infected canals. The price of the set is from 5,000 rubles.
Foredent has been the main material for filling root canals for many years due to its reliability, ease of use and availability. Analogs on the market are either too expensive or not as versatile and easy to use.
Purposes of use
Foredent is well suited for filling root canals after pulp removal. Intended for use in periodontal treatment and for the manufacture of fillings relating to the apical foramen (foramen apicale).
Filling material can also be used for additional surgical procedures (alveolotomy, root tip resection, periapical curettage).
Application of Foredent in dentistry
After depulpation, Foredent is most often used as a filler for the root canals of the tooth. It is also used in the treatment of periodontal disease with the installation of a filling in contact with the apical foramen. Material based on resorcinol-formaldehyde is often used for indirect third-party interventions: periapical curettage, dissection of the wall of the tooth alveolus, resection of root tips.
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.
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.
