1/21. Burkitt's lymphoma presenting with jaw lesions.We report an unusual case of Burkitt's lymphoma (BL) presenting with jaw lesions in a 14-year-old Chinese boy. The patient presented initially with mobile teeth in all 4 jaw quadrants, with corresponding radiographic detection of alveolar bone crest destruction and periapical bone resorption in the absence of clinically detectable jaw tumors. Moreover, radiographs taken only 17 days later showed clearly distinguishable signs of more extensive alveolar bone destruction compared with the initial radiographs.- - - - - - - - - - ranking = 1keywords = periapical (Clic here for more details about this article) |
2/21. Clinical effect of etidronate on alveolar pyorrhoea associated with chronic marginal periodontitis: report of four cases.Etidronate 200 mg daily was administered to four female patients with periodontitis and resultant alveolar pyorrhoea for periods of 2 weeks, followed by off-periods of 10 weeks or more, for 2-3 years. The macroscopic appearance of gingival mobility of the teeth, depth of periodontal pockets, and X-ray findings of alveolar bones improved markedly during this time. The effects were first observed after 6-12 months of treatment. These findings indicate that bisphosphonates may be effective in the treatment of periodontitis and resultant alveolar pyorrhoea. The effect may be mediated by the inhibitory action on bone resorption and the anti-inflammatory action of etidronate. Concomitant conventional dental management is also required.- - - - - - - - - - ranking = 954.89721120571keywords = periodontitis (Clic here for more details about this article) |
3/21. oral manifestations of congenital neutropenia or Kostmann syndrome.Infantile congenital agranulocytosis or Kostmann syndrome is a rare hereditary kind of severe neutropenia. The typical symptoms, which appear since the first days of life, are abscesses located on various parts of the body: ear, cutis, lung and oral cavity. These abscesses are due to an almost total disimmunity typical of the neutropenia. The aim of this article is to describe the most typical signs of this pathology in the oral cavity, reporting a case observed in our department in Florence, italy. On the basis of the personally observed case and of the review of the literature, it is possible to consider, as a characteristic finding in Kostmann syndrome, a typical very serious periodontal pathology, which is similar to the prepubertal periodontitis in deciduous dentition. At the age of 19 years the patient showed a dramatic compromise of the masticatory function. It is obvious that the lack of response of the host can obstruct the interaction between the host and the microbic flora, because the lack of neutrophils increases the susceptibility of the patient to every kind of infection, even to periodontitis. A periodontal prophylaxis, since the very first observations, followed by a rigorous maintenance with frequent and regular professional hygienic treatments could be effective in controlling the effects of periodontal disease and could reduce the tragic evolution. We need to recognise that it could be hard to monitor the oral situation correctly in these patients, as they have a continuously poor systemic condition. Finally in these cases the rehabilitative therapy is very problematical.- - - - - - - - - - ranking = 318.2990704019keywords = periodontitis (Clic here for more details about this article) |
4/21. Radiographic examination of dentigerous cysts in the transitional dentition.OBJECTIVES: To examine radiographically the relationship between the deciduous tooth and dentigerous cyst of the permanent successor during the transitional dentition. methods: From a retrospective review of all patients who visited our institution from April 1988 to August 2001, 70 patients under 16 years of age who had histologically confirmed dentigerous cysts that had developed from the central incisor to the second premolar were identified. These 70 patients were investigated using panoramic and periapical radiographs. RESULTS: In most cases (54 cases; 77.1%) the cyst was in the premolar region. Of the 54 premolars with dentigerous cysts, the overlying deciduous tooth had already been lost in 7 cases. Of the 47 remaining premolars with associated deciduous tooth, 35 (74.5%) had bone resorption of the periapical or bifurcation region, or irregular resorption of the associated deciduous tooth. Of the remaining 12 deciduous teeth with no periapical lesions, 9 had been treated with root canal therapy. Thus, 44 of these 47 cases (93.6%) had the possibility of inflammation at the deciduous tooth associated with the dentigerous cyst. Evidence from one case in the present study suggesting the process by which cyst development occurs is also given. CONCLUSION: Inflammatory change at the apex of the deciduous tooth may bring on a dentigerous cyst of the permanent successor.- - - - - - - - - - ranking = 3keywords = periapical (Clic here for more details about this article) |
5/21. Neoplasia masquerading as periapical infection.Seven examples of neoplasia which presented as periapical radiolucencies are described. These were all initially treated for presumed periapical infection. The atypical features that should alert dentists to the possibility of a tumour presenting in this manner are: a vital tooth with minimal caries, root resorption and an irregular radiolucent outline, tooth mobility in the absence of generalised periodontal disease, regional nerve anaesthesia, and failure to respond to good endodontic therapy. All material removed at the time of apical surgery must be examined histologically to prevent neoplasia being overlooked.- - - - - - - - - - ranking = 6keywords = periapical (Clic here for more details about this article) |
6/21. Osseo-integrated implant treatment of a patient with rapidly progressive periodontitis. A case report.The case report presented describes placement of osseointegrated fixtures in a patient with a probable history of rapidly progressive periodontitis. A 12-year history is presented. The post-operative sequelae of placing fixtures in a fully edentulous maxilla and partially edentulous mandible were the worst seen by the Implant Team at Emory University. The hypothesis presented is that patients with aggressive forms of periodontal disease should be subjected to appropriate mechanical and antimicrobial therapy to produce a healthy oral flora before any implants are placed.- - - - - - - - - - ranking = 795.74767600476keywords = periodontitis (Clic here for more details about this article) |
7/21. A case report of chronic neutropenia: clinical and ultrastructural findings.This case report of severe periodontitis concerns a young male patient with chronic idiopathic neutropenia seen between 1981 and 1983 by the School of Dental medicine of Geneva and from 1984 to 1988 by the Eastman Dental Hospital of london. The patient was maintained by intermittent systemic antibiotics, subgingival chlorhexidine irrigation, conventional debridement, brushing, and wire-mesh and composite splinting of loose teeth. After leaving school, at the patient's express wish, the extreme downhill pattern of the periodontitis resulted in removal of affected teeth and overdenture construction. The extracted teeth and associated soft tissues were examined for relevant plaque and host response features. The intact morphotypes associated with the advancing front of the lesion were invariably Gram-negative or positive coccoid cells, or less commonly short rods, as in all documented forms of periodotitis. connective tissue destruction was associated with a leucocyte accumulation comprising mainly polymorphonuclear neutrophils (PMN) and plasma cells. Both were observed degenerated more deeply than in routine adult periodontitis, including PMN lysosome loss and lymphocyte maturation within peripheral blood vessels. Only in one instance, one part of the superficial connective tissue of one block contained bacteria. It was concluded that the features of plaque and the lesion suggest a typical first line of defence response as in other forms of periodontitis. From the consideration of the 10 years clinical history of the patient, it is clear that non-surgical management is possible even in extreme cases, without any compromise of the patient's oral or systemic health, and in accord with the patient's wishes.- - - - - - - - - - ranking = 636.5981408038keywords = periodontitis (Clic here for more details about this article) |
8/21. Clinical, microbiological and immunological studies of post-juvenile periodontitis.The present study includes the clinical, microbiological and immunological examinations of 2 patients with post-juvenile periodontitis. bacteroides intermedius was the predominant isolate from periodontal pockets with post-localized juvenile periodontitis. bacteroides gingivalis, bacteroides forsythus and actinobacillus actinomycetemcomitans were detected in samples from periodontal pockets with post-generalized juvenile periodontitis. IgG antibody levels to B. gingivalis were significantly higher in the patients than these of periodontally healthy group. Spirochetes, including treponema denticola, were found at very high frequencies in all samples from the patients.- - - - - - - - - - ranking = 1114.0467464067keywords = periodontitis (Clic here for more details about this article) |
9/21. Plaque control in the treatment of juvenile periodontitis.With the purpose of establishing to what extent "periodontosis" responds to total plaque control, 21 such patients were observed over periods ranging from 8 to 34 years. Total plaque control in the present context means complete removal of all supragingival plaque by the patient and complete removal of all subgingival plaque by the dentist. The results were evaluated in terms of the number of lost teeth and the percentage of lost attachment during the observation period. It was observed that "periodontosis" cases responded to total plaque control in the same way as do ordinary cases, but with periodontosis, incomplete plaque control on any teeth led to extremely rapid bone loss and eventually to extraction. The reason for this is the unusually rapid apical migration of the subgingival plaque which is the most typical feature of the juvenile periodontitis. Some attachment and some teeth were lost in most of the patients, but a sufficient number of teeth with a sufficient amount of supporting tissue were maintained to provide a set of natural teeth that functioned well. This study shows that the reduced resistance to the invasion of subgingival plaque can be compensated for by a correspondingly strong emphasis on total plaque control. The term "periodontosis" is misleading, and should be replaced by the name "juvenile periodontitis" as suggested by Lehner et al. (1974).- - - - - - - - - - ranking = 954.89721120571keywords = periodontitis (Clic here for more details about this article) |
