Periraduclar surgery is necessary if root canal treatment fails. Its outcome depends on a number of factors, one of which is the root-canal filling. The filling promotes cementum and bone formation, [21] [22] blocks bacteria, and is a barrier for the root canal.
On the other hand, the root canal filling material may be extruded from the apex leading to other complications. [citation needed] The X-ray in the right margin shows two adjacent teeth that had received bad root canal therapy. The root canal filling material (3, 4, and 10) does not extend to the end of the tooth roots (5, 6 and 11).
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 ...
It is a likely outcome of untreated dental caries (tooth decay), and in such cases it can be considered a sequela in the natural history of tooth decay, irreversible pulpitis and pulpal necrosis. Other causes can include occlusal trauma due to 'high spots' after restoration work, extrusion from the tooth of root filling material, or bacterial ...
A file is placed in the root canal and a radiograph is taken to establish the root length. Care should be taken to avoid pushing instruments through the apex; Remnants of the pulp are then removed using barbed broaches and files; The canal is flushed with hydrogen peroxide to remove debris and is then irrigated with sodium hypochlorite and saline
In an immature permanent tooth pulpal necrosis causes the development of the root to stop. This causes the walls of the root to become fragile and thin which can make these teeth more prone to cervical root fracture and ultimately the tooth may be lost. These teeth in the past were treated with the calcium hydroxide apexification technique.

These teeth often have thin root canal walls which are susceptible to fracture after treatment. Therefore, complete cleaning and shaping as well as obturation of these teeth are difficult or sometimes impossible, due to high risk of fracture during the procedure [ 48 ] Clinical outcome of regenerative endodontics can be observed within 6 months ...
