Endodontic treatment may fail for many reasons: one common reason for failure is inadequate chemomechanical debridement of the root canal. This may be due to poor endodontic access, missed anatomy or inadequate shaping of the canal, particularly in the apical third of the root canal, also due to the difficulty of reaching the accessory canals ...
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. [2] 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.
An unusual root canal shape, complex branching (especially the existence of horizontal branches), and multiple root canals are considered as the main causes of root canal treatment failures. (e.g. If a secondary root canal goes unnoticed by the dentist and is not cleaned and sealed, it will remain infected, causing the root canal therapy to fail).
A root end surgery, also known as apicoectomy (apico-+ -ectomy), apicectomy (apic-+ -ectomy), retrograde root canal treatment (c.f. orthograde root canal treatment) or root-end filling, is an endodontic surgical procedure whereby a tooth's root tip is removed and a root end cavity is prepared and filled with a biocompatible material.
While millions of root canal treatments are carried out in the United States alone each year, total numbers of such cases do not provide reliable indicators of frequency, even for symptomatic periapical periodontitis (given that root canal treatment is not always indicated or complied with, and may also be performed in the absence of ...
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.
Many Medicare Advantage plans offer coverage for routine dental treatment, including root canals. According to the Kaiser Family Foundation, around 98% of people with Medicare Advantage have ...
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.
