Postępowanie w przypadkach resorpcji wewnętrznej korzenia w zębach stałych

From the information collected by clinical examination and CBCT, several options may be considered:

• therapeutic abstention and monitoring, in absence of infectious signs and symptoms,
• orthograde root canal treatment, with three options depending on the absence or presence of perforation of the radicular wall: complete root canal filling with gutta percha on nonperforated lesions; combined gutta percha in the root canal and MTA fillings for the perforation area; complete filling with a bioactive material (MTA or Biodentine) on apical perforated lesions located in a short root length,
• retrograde apical treatment,
• extraction and replacement by implants: the nonconservative treatment is indicated if the tooth is too weakened to be treated or restored.

Conservative dental treatments of resorbed teeth

Root canal treatment remains the treatment of choice of internal root resorption as it removes the granulation tissue and blood supply of the clastic cells.

Internal root resorption presents specific difficulties in instrumentation and filling.

The access cavity preparation must be as conservative as possible to preserve tooth structure and avoid further weakening of the already compromised tooth. A brisk bleeding might impair visibility in teeth with active resorbing lesions until the apical pulp [...]
