Sodium hypochlorite is a commonly used irrigant in endodontic therapy to dissolve organic matter and kill microbes, allowing removal of infection source. [9] Case reports [10] suggest a risk to dental professionals of chemical burns to the eyes as a result of sodium hypochlorite exposure.
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 ...
In the absence of LC 50 data on the poisonous (toxic) constituent substances, the mixture may be assigned a packing group and hazard zone based on simplified threshold toxicity tests. When these threshold tests are used, the most restrictive packing group and hazard zone must be determined and used for the transportation of the mixture.
Symptoms may be due to infection in the periradicular tissue around a root-treated tooth, which can impede healing of the tooth after conventional root canal treatment. [2] 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 ...
Substances released by the body's immune system as a result of the connective tissue breakdown, such as cytokines and growth factors, contribute to the mobilization and proliferation of epithelial cells in the area. b. Bone resorption caused by metabolism of acidic substances produced by cysts contributes to cyst growth.
Regulation 7 requires that an employer prevent exposure to hazardous substances or, if this is not reasonably practicable, that they adequately control exposure. One of the main points of the COSHH risk assessment is to identify the measures that are to be used to avoid a hazard or reduce the level of risk associated with a hazard.
Risk of occurrence of a phoenix abscess is minimised by correct identification and instrumentation of the entire root canal, ensuring no missed anatomy. Treatment involves repeating the endodontic treatment with improved debridement, or tooth extraction. Antibiotics might be indicated to control a spreading or systemic infection.
Root canal treatment (also known as endodontic therapy, endodontic treatment, or root canal therapy) is a treatment sequence for the infected pulp of a tooth that is intended to result in the elimination of infection and the protection of the decontaminated tooth from future microbial invasion.
