Palaquium gutta. Gutta-percha is a tree of the genus Palaquium in the family Sapotaceae, which is primarily used to create a high-quality latex of the same name. The material is rigid, naturally biologically inert, resilient, electrically nonconductive, and thermoplastic, most commonly sourced from Palaquium gutta; it is a polymer of isoprene which forms a rubber-like elastomer.
Tooth discoloration is common following root canal treatment; however, the exact causes for this are not completely understood. [46] Failure to completely clean out the necrotic soft tissue of the pulp system may cause staining, and certain root canal materials (e.g. gutta percha and root canal sealer cements) can also cause staining. [46]
Failure of root canal treatment is directly related to the lack of seal on the coronal 1/3 and apical 1/3 portion. A. Coronal 1/3 The problem is with the Obtura backfill that is used in the warm gutta percha technique. Under the surgical microscope, there is an obvious gap between the heated and cooled gutta percha and the dentinal wall.
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 ...
A failed root canal treatment may also create a similar abscess. A dental abscess is a type of odontogenic infection , although commonly the latter term is applied to an infection which has spread outside the local region around the causative tooth.
After the endodontic procedure has been completed, and the root canal(s) is/are filled with the inert gutta percha root canal filling material, some gutta percha is removed from the canal space. Gutta percha can be removed mechanically (use of Gates Glidden), [9] thermally (use of System B Tip), [10] and chemically (use of chemical solvents ...
It is thought that excessive removal of dentine during procedures such as root canal treatment weakens the tooth. For this reason excessive canal shaping should be avoided. Fracturing may be caused by excessive forces placed on the tooth, such as during compaction of gutta-percha during the obturation phase of endodontics.
Their use in a push-pull fashion results in a high level of debridement on removal from the root canal. They should not be rotated more than 30 degrees as they are narrow and vulnerable to fracture. They are also used for removal of root canal filling materials e.g. gutta percha during secondary root canal treatment.
