The purpose of this study was to assess the participation of dental auxiliary personnel in five towns situated in Sao Paulo, Brazil. In 1994, a questionnaire was applied to all workers in public health dentistry positions, requesting information from 245 (75.4%) dental assistants and dental hygienists employed in oral health programs of these towns. The results showed that their participation in oral health promotion activities varies according to each town reality. In some local health systems, their working time are spent more in oral health promotion activities than dental clinic activities. The oral health promotion activities more often refer fluoride mouthrinse, dental plaque staining followed by supervised brushing and education activities carrying out in schools and health centers. The survey results indicated that the participation of dental auxiliary personnel in some towns is very important and contribute to improve public health dentistry practices directed to the oral health promotion.","PeriodicalId":77611,"journal":{"name":"Revista de odontologia da Universidade de Sao Paulo","volume":"12 1","pages":"329-336"},"PeriodicalIF":0.0,"publicationDate":"1998-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67651976","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}

NIH-3T3 fibroblasts were plated in Petri dishes. After 48 hours, when the cells were in confluence, \"primers\" and adhesives of two dentin bonding systems (Scotchbond Multipurpose Plus and Clearfil Liner Bond 2) were applied on glass slides, which were placed in the dishes. Composite resin and calcium hydroxide were also used. Polymerization, when required, was performed with a XL 1500 light unit. No material was used in the control group. All materials remained in contact with the cells for 24 hours, except for phosphoric acid, which was maintained for 20 seconds. After that, cells were counted in a hemocytometer and cell viability was obtained by tripan blue dye exclusion. The data were submitted to statistical analysis (ANOVA and Tukey's test). It was possible to conclude that all materials tested presented lower cell viability than the control group, except calcium hydroxide. Composite resin and phosphoric acid application caused similar viability rates as calcium hydroxide. \"Primers\" plus adhesive application of both adhesive systems produced similar cytotoxicicity, both causing smaller cell viability than that of calcium hydroxide group. No differences were found in relation to the cytotoxic effects of the components in both adhesive systems.","PeriodicalId":77611,"journal":{"name":"Revista de odontologia da Universidade de Sao Paulo","volume":"12 1","pages":"375-382"},"PeriodicalIF":0.0,"publicationDate":"1998-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67652508","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}

Samples of stimulated saliva were titrated without CO2 elimination. The assessment was carried out to study the influence of the loss of CO2 from the samples during the few minutes necessary for titration, and to standardize the instants for measuring pH. Saliva samples were titrated from 206 individuals from both genders, between 5 and 50 years of age, and in a proportion of 0.77 : 1 : 0.44, respectively of children, youngsters, and adults. Case frequency distribution; determination of average values of initial pH, pKa, µ equivalents related to titration end point and final pH; and estimate of the percentage of saliva titrated at a pH of 5.0 were calculated based on the data collected. The results were used to classify individuals according to their salivary buffer capacity by colorimetric pH determinations using 11,12, and 13 µ equivalents of H+/ml saliva, and were compared to case frequency distribution obtained from saliva titration data. The results indicate that 11 µ equivalents H+/ml of saliva is the most appropriate for clinically evaluating the salivary buffer capacity of our population.","PeriodicalId":77611,"journal":{"name":"Revista de odontologia da Universidade de Sao Paulo","volume":"42 1","pages":"247-251"},"PeriodicalIF":0.0,"publicationDate":"1998-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67651417","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}
