1/9. Reversible and irreversible painful pulpitides: diagnosis and treatment.The foregoing clinical evidence indicates that when pain is severe, or when mild to moderate pain is present with a previous history of pain in the aching tooth, with or without periapical radiolucency, the tooth is in the IRPP category. Treatment dictates endodontic therapy or extraction. On the other hand, when clinical evidence indicates that the pain is mild or moderate with no previous history of pain, normal pulp vitality, and there is no positive percussion sign, the pulp is in the RPP category. Treatment dictates indirect or direct pulp capping in teeth with or without periapical radiolucency. The success rate favours teeth with no periapical radiolucency, 98%; in teeth with periapical radiolucency the success rate is less favorable, 43%. Efforts should be made to maintain pulp vitality. Endodontic therapy can always be done, if in time the pulp develops necrosis.- - - - - - - - - - ranking = 1keywords = periapical (Clic here for more details about this article) |
2/9. Chronic pigmented purpura associated with odontogenic infection.Five patients with chronic pigmented purpura associated with odontogenic infection are described. Four patients had Schamberg's disease, and one had itching purpura. These patients were resistant to topical corticosteroid treatment, but appearance of purpuric spots ceased after treatment for periodontitis, pulpitis, or both. No circulating immune complexes were detected, and neither immunoglobulin nor complement was deposited in the papillary vessels of the skin. Odontogenic infection might be one of the precipitating factors for chronic pigmented purpura.- - - - - - - - - - ranking = 0.13868415196102keywords = periodontitis (Clic here for more details about this article) |
3/9. Inflammatory resorption caused by an adjacent necrotic tooth.A case history is presented with a large periapical lesion and a perforating resorption defect on a cuspid. Endodontic therapy was performed, presuming that the necrotic cuspid caused the inflammatory response. No radiographic healing was evident 18 months after endodontic therapy. Considerable healing was demonstrated 6 months later, following the extraction of an adjacent tooth with prior root canal therapy. It was concluded that the failing root canal therapy of the extracted tooth was the primary factor leading to the inflammatory lesion, the resorptive perforation of the adjacent tooth, and its pulpal necrosis. It has not been reported prior that inflammatory resorption can result from the pulpal necrosis of an adjacent tooth.- - - - - - - - - - ranking = 0.25keywords = periapical (Clic here for more details about this article) |
4/9. Periodontal repair of periapical lesions: the borderland between pulpal and periodontal disease.A series of cases demonstrating the destruction of periapical periodontal structures, without pulpal involvement has been presented. Treatment using both surgery and antibiotics resulted in extensive healing without any concommitant endodontic therapy. The results suggest that lesions affecting the apical periodontium are either periodontal or pulpal in origin. Careful diagnosis allows the maintenance of pulp vitality in cases where apical destruction has a source other than an infected pulp. The commonly held belief that lateral and accessory canals are a significant source of pulpal contamination from deep periodontal pockets has been questioned.- - - - - - - - - - ranking = 1.25keywords = periapical (Clic here for more details about this article) |
5/9. herpes zoster infection presenting as an acute pulpitis.A major reason for referral to an endodontic practice is management of pain. Most cases are diagnosed as being of pulpal or periapical origin. However, some turn out quite differently than their initial appearance. This case report presents a patient referred to the endodontic clinic because of symptoms mimicking an irreversible pulpitis. On examination no obvious cause of the symptoms could be found. The patient was treated conservatively after which a herpes zoster viral infection was diagnosed. This case stresses the importance of a thorough investigation of all signs and symptoms and the delay of definitive treatment until a diagnosis is made.- - - - - - - - - - ranking = 0.25keywords = periapical (Clic here for more details about this article) |
6/9. The endodontic-periodontal lesion: a rational approach to treatment.When a periapical lesion communicates with a deep periodontal pocket, the etiology can be either endodontic or periodontal. This article clarifies the relationship between pulpal and periodontal disease and presents a systematic approach to the diagnosis and management of endodontic-periodontal lesions. It also presents a case that demonstrates the successful treatment of teeth that appear to be hopelessly diseased.- - - - - - - - - - ranking = 0.25keywords = periapical (Clic here for more details about this article) |
7/9. Chronic focal sclerosing osteomyelitis associated with a cracked tooth. Report of a case.Chronic focal sclerosing osteomyelitis is a periapical lesion that involves reactive osteogenesis evoked by chronic inflammation of the dental pulp. In most cases, this lesion develops in the mandibular molar region in response to a low-grade infection of the pulp that results from a deep carious lesion. A case is presented in which incomplete tooth fracture was the apparent cause of this type of periapical pathosis.- - - - - - - - - - ranking = 0.5keywords = periapical (Clic here for more details about this article) |
8/9. Lower lip paraesthesia following restoration of a second premolar tooth. Case report.A forty year old female patient developed paraesthesia of the right side of her lower lip following the placement of an extensive pin-retained amalgam restoration in her lower right second premolar tooth. Radiographs indicated that the mental foramen was close to the apex of this tooth and it was assumed that postoperative pulpitis and periapical inflammation had caused the paraesthesia through the effects of pressure on the mental nerve. The paraesthesia resolved following endodontic treatment of the lower second premolar tooth and the patient has had no further signs or symptoms.- - - - - - - - - - ranking = 0.25keywords = periapical (Clic here for more details about this article) |
9/9. Intracoronal radiolucency in an incompletely erupted permanent molar with a diagnosis of pericoronitis: importance of radiographic examination.Because of clinical signs and symptoms, a diagnosis of pericoronitis in a partially erupted, partially impacted first molar was made. A more thorough diagnosis was made with the help of a periapical radiograph that showed caries and thus revealed an irreversible pulpitis. Appropriate treatment was the result.- - - - - - - - - - ranking = 0.25keywords = periapical (Clic here for more details about this article) |
