Root end resection is a procedure whereby a tooth’s root tip is removed, inflammatory lesions are treated and the root is protected against recurrent inflammation. This method of treatment enables normal bone restoration in place of the removed lesions and this process can be supported by using material that stimulates bone rebuilding. In most cases this procedure allows to save the tooth from extraction (95% effective). Due to an enormous progress in orthodontic treatment (endodontic microscopes, advanced devices for root preparation), such procedures are becoming rare.
When apical lesions cannot undergo endodontic treatment or when repeated canal treatment is not an option, root end resection becomes the only available therapy.
Root end resection procedure is indicated when:
- it is impossible to carry out endodontic treatment that reaches up to the very end of the canal (abnormal anatomical structure, “overgrown” root canal);
- the material filling the canal is extruded beyond the tip of the root, causing severe pain,
- aesthetic and functional prosthetic restoration in the form of a crown-root inlay and a prosthetic crown has been made, and an inflammatory lesion developed around the tip of the root that cannot be treated in any other way;
- the applied treatment fails to remove inflammatory lesions around the dental root.
Root end resection is usually carried out on single-root teeth (incisors, canine teeth); however in practice, the procedure may be carried out on any tooth that requires such treatment.
