Twelve volunteers 18 to 65 years of age, with moderate to severe periodontal disease, were randomly divided into Group A and Group B of 6 members each. Oral lavage procedure was performed to Group A and Group B received systemic administration of antibiotic for five days. Patients 1 & 2, 3 & 4 and 5 & 6 received minocycline HCI, Erythromycin and Ampicillin respectively. Microbiologic samples in the subgingival crevicular area in selected tooth exhibiting clinical periodontal breakdown were obtained from all the subjects prior to and after the oral lavage procedure and systemic drug administration. Streptococcus viridans is the most predominant aerobic microorganism obtained from 83% of samples. However no anaerobic microorganism has been isolated. Bacterial sensitivity testing showed 60% of samples with positive growth of microorganisms (S. viridans) were also equally sensitive to Minocycline HCI, Erythromycin and Ampicillin. Oral lavage proved to be ineffective in reducing the number of bacteria. However, systemic drug administration revealed that there was a reduction in bacterial count after taking such antibiotics for five days which is more favorable to Minocycline HCI.</p>","PeriodicalId":76681,"journal":{"name":"The Journal of the Philippine Dental Association","volume":"46 1","pages":"4-12"},"PeriodicalIF":0.0,"publicationDate":"1994-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20389497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cells were identified in two compartments of the oral mucosa, the epithelium and subepithelial connective tissue. One hundred cases of neutral-buffered formalin-fixed paraffin embedded biopsy materials including 10 cases of acetone-fixed frozen tissue sections were studied immunohistochemically. In the main lymphoid population of each groups, the T lymphocytes predominated over the B lymphocytes. The lymphoid cells were present either as diffuse aggregates or organized in follicular patterns with or without germinal center-like structures. When present, B lymphocytes were seen to constitute the above mentioned structures. T lymphocytes made up the paracortical areas. A decrease in CD4/CD8 ratio was observed in cases with severe dysplasia. Specimens classified as mild to severe dysplasia presented a significant increase in the number of CD1a (+) dendritic Langerhans cells when compared with those of epithelial hyperplasia. A significant increase in macrophage count was also obtained in the subephitelial connective tissue of all dysplastic cases. A significant increase of CD57 (+) natural killer/killer cells in the subephitelial connective tissue and HLA-DR expression by the keratinocytes was observed in cases with severe dysplasia. Correlation and analysis of the results revealed an immunocellular reaction that varied according to the degree of dysplasia in oral leukoplakia. Immunologic events, i.e. decreased CD4/CD8 ratio, increased density of natural killer/killer cells and HLA-DR expression by keratinocytes, occurring simultaneously in severe dysplasia are speculated to be indicative of early malignant transformation.","PeriodicalId":76681,"journal":{"name":"The Journal of the Philippine Dental Association","volume":"47 1 1","pages":"3-18"},"PeriodicalIF":0.0,"publicationDate":"1994-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2330/JORALBIOSCI1965.36.87","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68752285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
