What is retrograde filling and features of its implementation

Retrograde filling is a method of filling root canals with access through the root apex. It is indicated if it is impossible to carry out this procedure using the standard algorithm. Most often, it is used if it is impossible to remove previously installed filling material from the canal, although there are a number of other cases when this method is indicated. With the right approach, it prevents the penetration of pathogenic microorganisms through the root canals into periodontal tissue and alveolar bone and ensures effective closure of the apex area (root apex).

Indications and contraindications for retrograde filling

Indications

• Impossibility of re-treatment of canals due to incorrectly previously filled canals using cement, pastes or their analogues, which does not allow unsealing;
• Anatomical features of the structure of the patient’s root canals, which are too long or have a strong curvature, which do not allow full endodontic treatment or make it impossible;
• Obliteration of root canals of various natures, including inflammation, malignant neoplasms, age-related changes and medical errors;
• The presence of fragments of endodontic files, anchor pins or stump inlays in the canal, which did not allow it to be hermetically sealed;
• The presence of a restoration on the tooth in the form of a fixed prosthesis, made of porcelain or metal ceramics, along with one or more of the above contraindications.

Contraindications

There are specific contraindications, which include mobility of teeth of the third or fourth degree due to periodontitis. At this stage of the disease, bone resorption exceeds 50% of the length of the tooth root, and the depth of the periodontal pockets is more than five millimeters.

In addition, there are a number of general contraindications that do not allow surgical dental interventions to be performed in the oral cavity. These include:

• Pregnancy in women;
• Periods of menstruation;
• Blood diseases that are characterized by disorders of blood clotting;
• Diabetes mellitus in the stage of decompensation;
• Infectious diseases in acute form;
• Chronic pathological conditions during periods of exacerbation;
• The patient has neoplasms of a malignant nature;
• Mental disorders.

The essence of retrograde root canal filling and the materials used

The essence of retrograde root filling is apicoectomy or resection of the root apex. This is a surgical operation that is aimed at removing the apical part of the tooth (including the pathological focus, if any). Having gained access to the canal, the dental surgeon processes and seals it.

Amalgam for retrograde tooth root filling

Despite a number of significant advantages, this material is used less and less often, since it can cause darkening of the gums, and the filling method is too labor-intensive. Today it is being replaced by modern materials that significantly simplify this procedure. At the same time, it is worth noting a number of advantages of amalgam:

• Ability to maintain a given shape well;
• Minimal shrinkage.

Zinc oxide eugenol cements for retrograde tooth root filling

COE are materials based on eugenol and zinc oxide. They are well compatible with dental tissues, as well as:

• Absolutely inert to them;
• They have antiseptic properties;
• Do not cause changes in hard dental tissues.

Their hardening time ranges from ten to twelve hours.

Glass ionomer cements for retrograde filling of tooth canals

GIC is the latest generation of materials with excellent strength and aesthetic properties. They are not susceptible to carious processes, allow you to select the desired shade, and provide radiographic contrast. Their other advantages:

• Functionality in wet environments;
• Excellent adhesion to different materials;
• Release of fluoride ions during the first year;
• Minimal shrinkage.

Materials

The standard retrograde filling procedure is performed using amalgam. Its main advantages are:

• minimal shrinkage;
• ability to hold shape.

It is worth noting that the use of this material is accompanied by some difficulties:

• the need for thorough drying of the surface of the cavity to be filled;
• impossibility of use in the smile area, which is associated with the likelihood of darkening of the mucous membrane;
• labor intensity.

Leading dental clinics regularly develop innovative filling materials that make it possible to reduce the labor intensity of procedures and at the same time improve their quality.

These include:

• zinc oxide eugenol cements (ZOE). The most popular lines: Cariosan, Cavitec, Dental Spofa, Super-EBA;
• pastes for intermediate restoration;
• glass ionomer cement compositions (GIC). The VOCO and Vitremer lines are considered the most popular.

Stages of manipulation

The procedure is carried out according to the following scheme:

1. Administration of local anesthesia. As a rule, submucosal infiltration is performed, but in some cases it is necessary to use transcortical anesthesia of bone tissue.
2. Separation of the gingival area from the jaw bone. To do this, the doctor makes incisions.
3. Resection of the root apex (before identifying the dental canals).
4. Treatment of the cavity with anti-inflammatory and antiseptic drugs. In the presence of extensive purulent foci, this manipulation is carried out several times.
5. Hermetically filling the prepared cavity with filling compounds followed by polymerization.
6. Repeated treatment with antiseptics.
7. Cutting off excess filling material.
8. Bringing the detached area of ​​soft tissue to its original state by applying sutures.

Sutures are removed on the fifth to eighth day after the intervention. After the procedure, patients are prescribed a three-day course of radiotherapy.

After surgery, the doctor re-orders an x-ray to correct any inaccuracies (if any are identified).

I am very grateful to Evgeniy Borisovich Antiukhin for removing my three eights. Especially considering that the lower tooth was not the simplest (it was located in an embrace with a nerve). The removal took place in 2 stages, one tooth under local anesthesia, two under general anesthesia. I had no idea that wisdom teeth could be... Read full review

Preparation for retrograde tooth root filling

Before prescribing retrograde filling to a patient, CELT dentists conduct a full diagnostic study. It is indicated for microsurgical intervention and includes:

• Thorough dental examination;
• Sight radiography/panoramic photo;
• Test for individual intolerance to filling materials.

If there are no contraindications to filling, the dentist performs sanitation of the oral cavity, after which the patient is ready for intervention.

Principles of retrograde filling of the reserved root canal

It is carried out in several stages, which are as follows:

• Infiltration anesthesia - local anesthesia with the introduction of an anesthetic with a syringe into the soft tissue of the gums;
• Providing access to the apex of the root of a dental unit - an incision along the gum and peeling off its mucous membrane exposing the bone jaw tissue and excision of the apex of the root to the level of detection of the canals;
• Antiseptic treatment - the cavity remaining after excision is cleaned, removing fragments of pathological tissue from it (if any), filling it with tampons with an antiseptic;
• Preparation for retrograde filling - the apex is thoroughly dried and etched, after which the cavity is washed and also dried;
• Retrograde filling - the canal cavities are filled with filling materials, covered with tampons for five minutes to harden, after which antiseptic treatment is carried out and excess composition is removed;
• Suturing - the detached flap of gum is returned to its place and secured with sutures. During the first 48 hours after surgery, drainage will be required to drain the ichor.

General overview

The retrograde filling method is an alternative to the standard root canal therapy method. The procedure is carried out to prevent the penetration of pathogenic microorganisms into the periapical region through the dental canals.

This technique allows for reliable closure of the apical region. The principle of manipulation is to perform an apiectomy (surgical resection of the tooth root in the apical zone). After preparing the canal, treatment is carried out, and then it is closed with filling material.

Recovery period after retrograde canal filling

The sutures are removed no earlier than after five days. During the recovery period, the patient must follow the doctor’s recommendations, which are as follows:

• During the first half hour, apply an ice compress to reduce swelling;
• Avoid consuming food or liquid for the first two hours;
• Avoid any physical activity for 24 hours;
• Carry out hygiene procedures regularly, but use a toothbrush with soft bristles;
• Systematically rinse the mouth with decoctions of chamomile and sage;
• Take antibiotics and stimulants according to the regimen prescribed by your doctor.

Will the filling hurt later?

Aching pain after treatment is normal

After returning from dentistry and the anesthesia wears off, many patients feel pain under the filling. Here you should not immediately panic and run back to the doctor. Pain most often acts as a natural response of the body to external intervention. It may hurt quite badly for a couple of days, but the nature of the pain is more aching than sharp. It may also be uncomfortable to brush your teeth or drink hot or cold drinks - then you can take a painkiller tablet or rinse your mouth with a soda solution. Over time, the pain subsides. According to practicing doctors, the pain lasts for about a week, but can last for a month (if, for example, a three-canal tooth was treated).

It is important to know! Pain after root canal filling may also indicate the development of complications due to incorrect therapy. Here you need to listen to your feelings - if the pain is acute, continuous, increases (and does not weaken every day) or is accompanied by a high temperature, then contact your dentist immediately.
