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 does not play any role in reinforcing or supporting the tooth and can in fact make it more likely to fracture at the root. [ 3 ] When deciding whether or not a tooth requires a post and core crown rather than a conventional crown, the following must be established: [ 4 ]
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).
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.
Tooth #5, the upper right second premolar, after extraction. The two single-headed arrows point to the CEJ, which is the line separating the crown (in this case, heavily decayed) and the roots. The double headed arrow (bottom right) shows the extent of the abscess that surrounds the apex of the palatal root.
For decayed adult (permanent) teeth, partial removal (also referred to as "selective removal" [5]) of decay before filling the tooth, or adding a second stage to this treatment where more decay is removed after several months, may be better than conventional treatment. [7]
Periapical dental radiograph showing chronic periapical periodontitis on the root of the left maxillary second premolar. Note large restoration present in the tooth, which will have undergone pulpal necrosis at some point before the development of this lesion. Specialty: Endodontics [1] Complications
