Anterior teeth typically do not require full coverage restorations after a root canal procedure, unless there is extensive tooth loss from decay or for esthetics or unusual occlusion. Placement of a crown or cusp-protecting cast gold covering is recommended also because these have the best ability to seal the treated tooth.
After endodontic therapy has been executed, or re-executed, successfully, and the canals can no longer provide a nutrient-rich habitat for microbes, [31] the issue of bone healing comes into focus. Ostensibly, then, for regeneration to occur, the root canal system must have been decontaminated and further access to microbial invasion must be ...
Procedures for root canal. The space inside the root canals is filled with a highly vascularized, loose connective tissue, called dental pulp. The dental pulp is the tissue of which the dentin portion of the tooth is composed. The dental pulp helps complete formation of the secondary teeth (adult teeth) one to two years after eruption into the ...
A full‐thickness mucoperiosteal flap is then raised to expose the root surfaces. The flap, incorporating the buccal/ lingual gingiva and alveolar mucosa, then has to be elevated beyond the mucogingival line in order to be able later to reposition the soft tissue apically. The marginal collar of tissue is then removed with curettes.
Disadvantages of amalgam include poor aesthetic qualities due to its colour. Amalgam does not bond to tooth easily, hence it relies on mechanical forms of retention. Examples of this are undercuts, slots/grooves or root canal posts. In some cases this may necessitate excessive amounts of healthy tooth structure to be removed.
Some dentists will also finish root canal treatment by covering the exposed tooth with a crown. [1] A crown is typically bonded to the tooth by dental cement. They can be made from various materials, which are usually fabricated using indirect methods. Crowns are used to improve the strength or appearance of teeth and to halt deterioration.
Removal of the necrotic pulp and the inflamed tissue as well as proper sealing of the canals and an appropriately fitting crown will allow the tooth to heal under uninfected conditions. [2] Surgical options for previously treated teeth that would not benefit from root canal therapy include cystectomy [12] and cystostomy. [12]
Mineral trioxide aggregate (MTA) is a recent development of the 1990s [21] initially as a root canal sealer but has seen increased interest in its use as a direct pulp-capping material. [10] The material comprises a blend of tricalcium silicate , dicalcium silicate and tricalcium aluminate ; bismuth oxide is added to give the cement radiopaque ...
