Root canal treatment (also known as endodoncja) is a procedure that saves the tooth from loss (extraction), consisting of removing infected or dead pulp, thorough preparation (cleaning), and disinfection of root canals, as well as their tight filling and reconstruction of the tooth crown.

When it is necessary

Root canal (endodontyczne) treatment is performed when decay, trauma, or a crack leads to inflammation or necrosis of the pulp, manifesting as pain, sensitivity, swelling, or the presence of periapical lesions in imaging studies. Indications also include failures of earlier therapy and ailments despite correct fillings and crowns.

Root canal treatment under a mikroskop (microscopic endodoncja) allows for several-fold magnification of the operative field (up to 25 times), enabling the doctor to more precisely locate, clean, and disinfect the tooth canals and subsequently fill them.

The basic benefits of treatment under a mikroskop are:

• • greater precision of the procedure,
  • minimization of the risk of complications and re-infection (often allowing the tooth to be saved, which would have had to be extracted using classical methods),
  • possibility of identifying details invisible to the naked eye (e.g., micro-cracks, additional canals, or branches affecting the therapy's success)
  • increased safety and comfort (the procedure is painless, performed in a well-lit and magnified area),
  • shortening of the treatment time and the need for repeat visits (treatment is sometimes performed even in a single visit),

Step-by-step process

• • Comprehensive diagnostics: interview, clinical examination, RVG/CBCT image to assess anatomy, working length, and periapical lesions.
  • Anesthesia and koferdam isolation: ensuring comfort and an aseptic treatment field.
  • Opening the chamber and removing the pulp: gaining access to the canals and eliminating infected tissues, preferably under mikroskop control.
  • Preparation and disinfection: mechanical-chemical shaping of canals with manual/rotary instruments and irrigation with antiseptic agents.
  • Filling: tight obturation (filling) with gutta-percha and sealer, radiological control.
  • Restoration: from filling to post and crown, depending on tissue loss.

Time and number of visits

A simple case can be completed in a single visit, while complex cases involving complicated anatomy, root canal re-treatment, or acute symptoms often require 2–3 appointments with intermediate treatment (dressings).

Effectiveness and prognosis

Properly performed root canal treatment achieves high success rates with appropriate restoration and marginal seal, whereas more difficult cases (large lesions, posterior teeth, reendo) have a lower prognosis without magnification and thorough disinfection. The use of a microscope and CBCT increases predictability through better canal localization and more precise quality control.

Possible complications

Risks include:

• • missed or hard-to-reach canal,
  • perforation,
  • instrument fracture,
  • insufficient disinfection,
  • obturation leakage
  • root fractures.

This may result in the persistence of lesions or the need for re-treatment or possibly microsurgery. In case of failure, re-treatment, apicoectomy, or ultimately extraction and implantation or another prosthetic replacement is possible.

What determines success

• • Comprehensive diagnostic imaging and proper identification of canal anatomy.
  • Proper asepsis and rubber dam isolation, as well as effective irrigation.
  • Complete and duly diligent preparation of all canals and tight obturation (filling of the canals).
  • Post-endodontic restoration ensuring strength and marginal seal, ideally as soon as possible after treatment.
