In the first part of this paper the features of fluoride varnishes in terms of fluoride uptake, caries prevention and toxicological safety are discussed. The effect of both varnishes under high cariogenic conditions is discussed in the second part. In the presented study, 8 patients carried 3 enamel specimens (Fluor Protector, Duraphat, Control) intra-orally during 4 months. They kept plaque accumulation intact on the specimen and avoided fluoride administration from other sources. After 4 months of substantial cariogenic challenge, the enamel was analysed by microradiography and the degree of caries protection obtained for each varnish type was calculated. The results show that under high-risk caries conditions enamel treated with Fluor Protector was significantly better protected (65%) than enamel treated with Duraphat (3%).</p>","PeriodicalId":19550,"journal":{"name":"Oral-prophylaxe","volume":"10 2","pages":"61-7"},"PeriodicalIF":0.0,"publicationDate":"1988-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14402166","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}

The considerable qualitative and quantitative variation of microorganisms, predominantly Streptococcus mutans, depends on age, thickness, and acidogenicity. The food passing through the mouth is also a crucial factor. Plaque removal (plaque control) is the most important measure for prevention of caries and gingivitis. Since mechanical removal of plaque is not adequate, chemical agents must also be used. Fluoride, for example, effectively inhibits plaque metabolism. The efficacy of enzymes, alkaloids, and antiseptics is limited. No active immunization against cariogenic streptococci is available at present. Mechanical, chemical, and biological measures of plaque control are effective only when the population is motivated to practice oral hygiene.</p>","PeriodicalId":19550,"journal":{"name":"Oral-prophylaxe","volume":"10 1","pages":"18-27"},"PeriodicalIF":0.0,"publicationDate":"1988-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14210431","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}

At the beginning of the study, a dental hygienist cleaned the right or left side of the jaw of each subject with a manual V-form toothbrush or an electric toothbrush; the other side was manually cleaned with a multi-tufted toothbrush. At the second cleansing one week later, the same dental hygienist cleaned the side contralateral to that brushed in the first test week with the multi-tufted brush; the manual V-form brush was used instead of the electric toothbrush and vice versa. The number of new gingival lesions was recorded after each brushing. The cleansing effect was established by determining the amount of residual plaque. The subjects did not know which type of toothbrush was used to cleanse the evaluated side of the jaw. The results showed that the manual V-form toothbrush abraded the gingiva more than the electric toothbrush (p less than 0.005). A similar difference was found between the manual multi-tufted and the electric toothbrush (p less than 0.05).
