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).
A root canal is the naturally occurring anatomic space within the root of a tooth.It consists of the pulp chamber (within the coronal part of the tooth), the main canal(s), and more intricate anatomical branches that may connect the root canals to each other or to the surface of the root.
The post on the left is a tapered post, the one on the right is a parallel post. In post and core fabrication, it is desirable that the post descend at least two-thirds of the length of root canal (or not less than the height of the crown) in order to provide sufficient retention.
A periapical radiograph is usually the radiograph of choice. When examining the tooth which will receive surgery, the quality of the root treatment and canal anatomy (sclerosed or missed canals) is noted. More than one radiograph may be required to indicate possible treatment success. The root filling should be optimal.
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 ...
From the history, indicators of pulpal, periodontal, a combination of both, or non-dental causes can be observed. Periodontal pain is frequently localized to a particular tooth, which is made much worse by biting on the tooth, sudden in onset, and associated with bleeding and pain when brushing. More than one factor may be involved in the ...
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). Different types of ...
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.
