Treatment of canals under a microscope is required when:
- during the started endodontic treatment, complications arose – the canal was blocked, perforated, the instrument was broken, etc.;
- the canals have been treated earlier and the tooth hurts, there is an abscess in the gums, or a focus is visible on the X-ray photo;
- the tooth is planned to be prosthetic and the canals previously poorly treated are visible on the X-ray picture;
- the tooth hurts, caries has reached the soft tissues (nerve) inside the tooth, and after taking an X-ray, it is seen that the canals are complex – narrow, curved, calcified, etc.;
- the tooth is planned to be prosthetic, and there is a permeable or fallen out temporary filling in the tooth, there is a suspicion that the bacteria from the mouth have reached the previously sealed canals.
Endodontic treatment is carried out during one or several visits. The duration of treatment depends on the number of canals (in one tooth there may be 1-4 canals) and the complexity of the situation. After taking an X-ray, for the assessment of the initial situation and the diagnosis, the treated tooth is anaesthetized (if necessary) and isolated from the oral cavity.
Endodontic treatment consists of three main stages:
- the passage of the canal to the apex of the root. This is one of the most difficult stages, since the canals are often very narrow (0.06 – 0.10 mm in diameter), calcified. If the canals have already been treated before, they may have cement inside them, an old filling material, broken instruments that prevent the passage of the canal to the end. In our clinic, a microscope, ultrasound and other modern instruments and devices are used for the treatment of such narrow canals and for the re-treatment of previously treated canals.
- cleaning the canal. During this stage, the canals are distributed, clearing the dirt remaining in the canal, old sealing materials. There are many branches in the canals, which metal instruments cannot reach, so the canals are washed with various disinfecting solutions.
- canal sealing. After the canal is distributed, it is filled. After high-quality sealing of the canal, there is no room for microorganisms in it and the tooth is ready for restoration with a filling or prosthetics with a crown. Until this, the tooth is restored with a temporary filling.
