Because periapical disease is almost inevitably preceded by pulp disease, [1] proper chemomechanical debridement of the infected root canals, together with incision and drainage of associated periradicular swellings, will usually allow for rapid improvement in patient signs and symptoms. [15]
Risk of occurrence of a phoenix abscess is minimised by correct identification and instrumentation of the entire root canal, ensuring no missed anatomy. Treatment involves repeating the endodontic treatment with improved debridement, or tooth extraction. Antibiotics might be indicated to control a spreading or systemic infection.
The root canal filling material (3, 4, and 10) does not extend to the end of the tooth roots (5, 6 and 11). The dark circles at the bottom of the tooth roots (7 and 8) indicated infection in the surrounding bone. Recommended treatment is either to redo the root canal therapy or extract the tooth and place dental implants.
Pulp infection [3] Risk factors: Dental caries, dental trauma, dental procedures, [3] professional misconduct [4] Diagnostic method: Apical Radiolucencies, Apical Radiopacities [5] Treatment: Root canal treatment, [1] periradicular surgery, [6] retrograde root canal treatment [7] Medication: Antibiotic in case of a sudden onset of symptoms in ...
A failed root canal treatment may also create a similar abscess. A dental abscess is a type of odontogenic infection, although commonly the latter term is applied to an infection which has spread outside the local region around the causative tooth.
The infected tissue of the periapical cyst must be entirely removed, including the epithelium of the cyst wall; otherwise, a relapse is likely to occur. Root canal treatment should be performed on the tooth if it is determined that previous therapy was unsuccessful.
The most basic treatment for teeth with pulpal necrosis is root canal treatment. This involves the use of biologically accepted mechanical and chemical treatment of the root system, followed by the placement of a root filling, allowing healing of the periradicular tissues to occur.
