Periradicular surgery
In the dental specialty of endodontics, periradicular surgery is surgery to the external root surface. Examples of periradicular surgery include apicoectomy, root resection, repair of root perforation or resorption defects, removal of broken fragments of the tooth or a filling material, and exploratory surgery to look for root fractures.
Symptoms may be due to infection in the periradicular tissue around a root-treated tooth, which can impede healing of the tooth after conventional root canal treatment. After removing the pulp, the aim of endodontic treatment is to seal the pulpal space to prevent further bacterial contamination and allow healing of the periradicular tissue. Success rates for root-canal treatment range from 47 to 97 percent; failures may be due to spaces in the root-canal filling, a root filling which is too short or a preexisting periapical lesion.
Treatment options are nonsurgical root-canal re-treatment or periradicular surgery. Although accessing and cleaning the pulp chamber and canals would be easier with the former, it is contraindicated in some patients.
The stages of periradicular surgery are:
Periradicular surgery should be very considered where previous endodontic treatment has failed, and possible re-root treatment is the preferred option. If re-root treatment is not possible, will not correct the problem or patient factors prevent it, periradicular surgery is indicated.
Anatomical deviations preventing access or preparation of canal, including root-canal calcification, pulp stones, severely curved roots, bifurcations, secondary roots, lateral canals, delta apexes, internal and external resorption resistant to conventional treatment and an incomplete apex, may prevent the complete cleaning and preparation of the canal.
Procedural errors include the formation of ledges, perforation of the root or floor of the pulp chamber, extruded root filling material, file breakages, or underfilled canals. These are only indications for periradicular surgery if they cause persistent periapical radiolucency, swelling and pain.
Exploratory surgery that identifies possible root fractures or perforations indicates periradicular surgery.
