After endodontic therapy has been executed, or re-executed, successfully, and the canals can no longer provide a nutrient-rich habitat for microbes, [31] the issue of bone healing comes into focus. Ostensibly, then, for regeneration to occur, the root canal system must have been decontaminated and further access to microbial invasion must be ...
Inadequate root canal therapy; Vertical root fractures; Foreign material in the lesion; Associated periodontal disease; Penetration of the maxillary sinus; Following conventional, adequate root canal therapy, abscesses that do not heal or enlarge are often treated with surgery and filling the root tips; and will require a biopsy to evaluate the ...

It is also the result of inadequate debridement during the endodontic procedure. 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.
Root canal procedure: unhealthy or injured tooth, subsequent creation of an access cavity with a dental handpiece, cleaning and shaping the root canals with an endodontic file, and restoration with gutta-percha filling and a crown Removing infected pulp during a root canal procedure. Root canal treatment (also known as endodontic therapy ...
Root canal treatment should be performed on the tooth if it is determined that previous therapy was unsuccessful. Removal of the necrotic pulp and the inflamed tissue as well as proper sealing of the canals and an appropriately fitting crown will allow the tooth to heal under uninfected conditions.
In root canal treatment, for example, more Lidocaine is required than for a simple filling. [ 2 ] Other local anesthetic agents in current use include articaine (also called septocaine or Ubistesin), bupivacaine (a long-acting anesthetic), prilocaine (also called Citanest), and mepivacaine (also called Carbocaine or Polocaine).
Periodontal abscesses may be difficult to distinguish from periapical abscesses. Since the management of a periodontal abscess is different from a periapical abscess, this differentiation is important to make (see Dental abscess#Diagnostic approach) For example, root canal therapy is unnecessary and has no impact on pain in a periodontal abscess.
