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.
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).
Failure of root canal treatment is directly related to the lack of seal on the coronal 1/3 and apical 1/3 portion. A. Coronal 1/3 The problem is with the Obtura backfill that is used in the warm gutta percha technique.
Ostensibly, then, for regeneration to occur, the root canal system must have been decontaminated and further access to microbial invasion must be prohibited. Regeneration of the bone has been demonstrated to occur, on average, at a rate of 3.2 mm² per month, and studies suggest that 71% of lesions have achieved complete resolution one year ...

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.
When the root is incompletely formed in adolescents and an infection occurs, apexification can be performed to maintain the tooth in position as the roots develop. In case of non-vital pulp: 1. Isolate the tooth with a rubber dam 2. perform root canal treatment. 3. Mix MTA and insert it to the apex of the tooth, creating a 3 mm thickness of ...
