Endodontics: standard endodontic treatment of a discolored maxillary canine tooth in a dog

Pulpitis and subsequent pulp necrosis results in tissue degradation by‐products causing staining of the dentin.This is a common cause of localised intrinsic staining of the teeth. Reversible pulpitis is a condition of pulpal inflammation in which the pulp can be returned to the normal state if the cause of the pulpitis is treated or removed; however, if this is not achieved, the condition will progress to irreversible pulpitis and pulp necrosis. If left untreated, a tooth with pulp necrosis can result in periapical abscess, radicular cyst, granuloma, fistula, osteomyelitis, pathological fracture, periodontal disease and tooth loss. The treatment options for a tooth with pulp necrosis include endodontic or exodontic therapy. The purpose of endodontic therapy is to alleviate pain and to treat or prevent inflammation and infection in order to preserve the tooth function. This case report describes the endodontic treatment of a discolored left maxillary canine tooth in a dog.
