摘要:

AbstractPaget's disease of bone (osteitis deformans) is a relatively common disorder of uncertain aetiology. It is characterised by abnormal resorption and apposition of osseous tissue in one or more bones of the skeleton. This paper is a review of Paget's disease with particular reference to dentistry. The prevalence, aetiology, clinical features, radiography, histopathology, biochemistry, oral and dental manifestations, complications and treatment are discussed. One hundred and fifty‐two reported cases of Paget's disease of the jaws have been analysed. The upper jaw was more frequently involved than the lower jaw in the ratio of more than 2:1. This survey shows a higher prevalence of Paget's disease in the mandible than previously recorde

摘要:

A total of 57 bacterial strains were isolated from tooth surfaces, oral mucosa, skin of the upper lip, and rectum of 3 persons. Identification of the strains indicated that each type of surface had a characteristic microflora. Aggregation of bacterial suspensions, induced by salivary agglutinins, was measured spectrophotometrically as the decrease in optical density (OD) by time. The aggregation curves for the oral strains followed a sigmoid pattern. The aggregation rates varied between individuals and strains. Most fecal strains showed an aggregation pattern which differed from that of the oral strains and was characterized by only a small, initial decrease in OD. The few strains, mainlyPropionibacteriumstrains, collected from the skin of the upper lip did not aggregate. It appears from the data that several mechanisms are involved in the retention of bacteria to surfaces.

摘要:

Four bacterial strains collected from tooth surface, oral buccal mucosa, skin of the upper lip, and rectum were used to evaluate the specificity of salivary agglutinins. A saliva sample was absorbed with each of the strains, and the remaining supernatants were tested for agglutinin activity against all strains. The effect of concanavalin A and pH on theS. mutansandS. mitioragglutinins was studied. The conclusion was drawn that the agglutinins for theS. mutansandS. mitiorstrains differed but that theS. mitiorstrain tested carried a receptor site for theS. mutansagglutinin without becoming agglutinated. TheS. mutansagglutinin seems to have either unsubstituted mannopyranosyl or N‐acetylated glucopyranosyl residues as structural component

摘要:

AbstractUsing a serotypecstrain ofStreptococcus mutanswe found that the agglutinating activity could be quantitatively absorbed, and desorbed from the micro‐organisms by a phosphate buffer. The desorbed agglutinin was found to be inactive in the absence of calcium. Calcium alone did not induce aggregation. At 0.1 mM calcium most of the activity was regained. Other cations could not substitute for calcium. On a molecular basis the ratio between calcium and agglutinin or bacteria is high, in the order of 107and 104respectivel

摘要:

Mature mouse mandibular third molars together with their periodontal ligaments and alveolar bone were isografted to two heterotopic sites: the renal subcapsular site and the tibial shaft medulla. The pulps and periodontal ligaments of the grafts underwent cellular degeneration after Transplantation but demonstrated signs of revascularization and cellular repopulation 7 days after Transplantation. Grafts obtained at 28, 60 and 100 days after Transplantation demonstrated a significant decrease in the width of the periodontal ligament, a decrease in the number and organization of mature periodontal fibre bundles, the appearance of fibres arranged parallel with the root surface and a decrease in the thickness of surrounding alveolar bone. These regressive changes in the periodontal ligament were considered to be due primarily to the nonfunctional status of the teeth at the two heterotopic sites.

摘要:

AbstractCo‐60 gamma irradiation of the salivary glands ofMacaca mulatamonkeys fed a cariogenic diet led to the rapid onset of dental caries resembling that in irradiated human patients. Plaque fluid and saliva were sampled from irradiated monkeys, nonirradiated controls and a group of animals fed a noncariogenic diet in order to look for changes which might occur in inorganic composition related to the caries development and to dietary differences. Salivary calcium and phosphate levels were not markedly changed after irradiation: iodide levels were raised, while thiocyanate levels fell. In plaque fluid, calcium concentrations were not affected by irradiation, but were higher in animals fed a noncariogenic diet. Phosphate levels were higher with a cariogenic diet and further increased in irradiated animals. Magnesium levels were occasionally higher than those of calcium. Other differences in plaque fluid composition may be related to secondary effects of the concomitant gingival disease. The results do not point clearly at a specific change in the quality of the saliva produced by the residual gland tissue after irradiation which precipitates the rampant caries. II is more likely that the great reduction in the quantity of saliva with its protective constituents is responsibl

摘要:

AbstractUsing an immunoperoxidase method we have demonstrated carcinoembryonic antigen (CEA) in more than half of a series of 62 tumors of minor salivary glands. CEA was present in both benign and malignant tumors. Its presence was related mainly to the formation of well differentiated ductal tissue in the neoplasms rather than to the histologic type of tumor. Although of only limited diagnostic value, the histologic presence of CEA in a particular tumor may indicate the possibility of postoperative monitoring of saliva and plasma, particularly where residual tumor, metastases or recurrences arc considered likely.
