The organotypic cocultures were treated with tetracycline (TC) or minocycline (MINO) at 10-300ƒÊM for 1 week and multilayered epithelial cells were examined by hematoxylin-eosin staining and immunohistochemistry. Treatment with TC at 30ƒÊM did not affect multilayer formation of epithelial cells, but the formation was inhibited by treatment with TC at 100ƒÊM or more. Treatment with MINO at 10ƒÊM did not affect the multilayer formation, but the formation was inhibited by treatment with MINO at 30 ƒÊM or more. These values were greater than their MIC90 concentrations for periodontopathic bacteria, including Porphyromonas gingivalis, Prevotella intermedia, and Actinobacillus actinomycetemcomitans. These results suggested that topical administration of TC or MINO to the periodontal pocket at their MIC90 concentration for periodontopathic bacteria would have few adverse effects on the growth of the periodontal ligament.","PeriodicalId":19590,"journal":{"name":"Oral Therapeutics and Pharmacology","volume":"26 1","pages":"19-27"},"PeriodicalIF":0.0,"publicationDate":"2007-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"63819827","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}

Since severe drug eruptions and rashes can affect internal organs in addition to skin and mucosa and can result in permanent disabilities, they must be diagnosed and treated as soon as possible. The vital elements of effective diagnosis are to clearly grasp which types of reactions are the most severe and to quickly identify the reactions which may become serious or threatening. We have found in our own practice that the most serious types of drug erosions and rashes are those that affect the whole body. There is a possibility that a very serious case may develop if an erosion of the oral mucosa spreads out beyond the region of the lip where the mucosa changes to skin or if erythema of the epidermis quickly spreads and red spots grow together over a relatively large area. The treatment is to immediately stop taking all suspect drugs and begin a rigorous course of steroids.","PeriodicalId":19590,"journal":{"name":"Oral Therapeutics and Pharmacology","volume":"25 1","pages":"80-87"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"63819959","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}

Probiotics have been developed for use in the prevention of intestinal infections, and the treatment of antibiotic-associated diarrhea and intestinal malfunction. Recently, the use of probiotics has come to exert a wide range of different effects such as the suppression of Helicobacter pylori, and the prevention of allergic disease. Moreover, evidence for the clinical effectiveness of probiotics has been reported in their use for the prevention and treatment of dental caries and periodontal diseases. For example, the administration of a dairy product containing L. rhamnosus appeared to reduce the risk of dental caries in a randomized, double-blind, placebo-controlled trial. This trial demonstrated reduced levels of dental caries and lower mutans streptococcal counts in probiotics patients after seven months of administration. From the viewpoint of periodontal diseases, it has been suggested that L. salivarius decrease the risk of periodontal disease by eliminating black-pigmented anaerobic rods (BPARs) which have been suspected of playing a role in periodontal disease. Yogurt may suppress the number of mutans streptococci in saliva and improve halitosis. However, there is little available information about the use of probiotics in dentistry. In addition, the role of indigenous Lactobacillus and Bifidobacterium on oral health, the adhesion of probiotics in the human oral cavity, and the mechanisms of probiotics against cariogenic and periodontopathogenic bacteria have not been clarified. In this review, the authors would like to address the possible use and problem of probiotics in dentistry.","PeriodicalId":19590,"journal":{"name":"Oral Therapeutics and Pharmacology","volume":"699 1","pages":"61-68"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"63819603","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}
