Exposure of the pulp causes pulpitis (an inflammation which can become irreversible, leading to pain and pulp necrosis, and necessitating either root canal treatment or extraction). [1] The ultimate goal of pulp capping or stepwise caries removal is to protect a healthy (or reversibly inflammed) dental pulp, and avoid the need for root canal ...
“The tooth may have had a filling or decay or an existing crack, which is common in people who grind their teeth," says Lies. "Teeth that have had a root canal treatment tend to be more brittle ...
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 ...
After removing the pulp, the aim of endodontic treatment is to seal the pulpal space to prevent further bacterial contamination and allow healing of the periradicular tissue. Success rates for root-canal treatment range from 47 to 97 percent; failures may be due to spaces in the root-canal filling, a root filling which is too short or a ...
Prevent dentine hypersensitivity; Exposed dentinal tubules in vital teeth can be covered with temporary crowns to prevent any dentinal fluid movement. Prevent coronal leakage; Temporary crowns block bacteria entry to prevent pulpal inflammation and maintain a good coronal seal to the root canal filling. [3] [4]
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).
Composites and amalgam are used mainly for direct restoration. Composites can be made of color matching the tooth, and the surface can be polished after the filling procedure has been completed. Amalgam fillings expand with age, possibly cracking the tooth and requiring repair and filling replacement, but chance of leakage of filling is less.
In internal resorption, root canal therapy is performed, a putty mixture of MTA is inserted in the canal using pluggers to the level of the defect. Gutta percha and root canal sealer are placed above the defect to complete the root canal treatment. In direct cases, the canal may be completely obturated with MTA.
