To evaluate oral health literacy, independent of other oral health determinants, as a risk indicator for self-reported oral health. Methods. A cross-sectional population-based survey conducted in Tehran, Iran. Multiple logistic regression analysis served to estimate the predictive effect of oral health literacy on self-reported oral health status (good versus poor) controlling for socioeconomic and demographic factors and tooth-brushing behavior. Results. In all, among 1031 participants (mean age 36.3 (SD 12.9); 51% female), women reported brushing their teeth more frequently (P < 0.001) and scored higher for oral health literacy (mean 10.9 versus 10.2, P < 0.001). In the adjusted model, high age (OR = 1.01, 95% CI 1.003-1.034), low education (OR = 1.88, 95% CI 1.23-2.87), small living area in square meters per person (OR = 1.85, 95% CI 1.003-3.423), poor tooth brushing behavior (OR = 3.35, 95% CI 2.02-5.57), and low oral health literacy scores (OR = 1.58, 95% CI 1.02-2.45) were significant risk indicators for poor self-reported oral health. Conclusions. Low oral health literacy level, independent of education and other socioeconomic determinants, was a predictor for poor self-reported oral health and should be considered a vital determinant of oral health in countries with developing health care systems.","PeriodicalId":89396,"journal":{"name":"ISRN dentistry","volume":"2013 ","pages":"249591"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1155/2013/249591","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"31349804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Antimicrobial activity was evaluated by agar diffusion test using the following strains: Micrococcus luteus, Streptococcus mutans, Enterococcus faecalis, Pseudomonas aeruginosa, and Candida albicans. After 24 hours of incubation at 37°C, inhibition of bacterial growth was observed and measured. For pH analysis, material samples (n = 10) were placed in polyethylene tubes and immersed in 10 mL of distilled water. After 12, 24, 48, and 72 hours, the pH of the solutions was determined using a pH meter. Results. All microbial species were inhibited by the cements evaluated. All materials composed of PC with radiopacifying agents promoted pH increase similar to pure Portland cement. ZOE had the lowest pH values throughout all experimental periods. Conclusions.

To evaluate the antibacterial activity of four endodontic sealers on Enterococcus faecalis by a direct contact test. Material and Methods. Enterococcus faecalis was used as a test organism. Direct contact test which is based on measuring the effect of close contact between test bacteria and tested material on the kinetics of bacterial growth was performed to overcome the disadvantages of agar diffusion test. The sealers tested were zinc oxide eugenol-based sealer, glass-ionomer-based sealer, polydimethyl-siloxane-based sealer, and urethane dimethacrylate resin-based sealer. Data was collected by recording the optical density with the help of a spectrophotometer. Results. The sealers exhibited different inhibitory effects. The results obtained were subjected to statistical analysis by Kruskal Wallis analysis of variance and Dunn's multiple comparison test. Group comparison showed very highly significant difference between the groups. Conclusion. Zinc oxide eugenol-based sealer was the most effective and urethane dimethacrylate resin-based sealer was the least effective against Enterococcus faecalis, whereas glass-ionomer-based and polydimethyl-siloxane-based sealers were effective only for a short period. Inhibition of the bacterial growth is related to the direct contact of the microorganism with the sealer.","PeriodicalId":89396,"journal":{"name":"ISRN dentistry","volume":"2012 ","pages":"989781"},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3408652/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30830340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The numerical density of inflammatory cells in the capsule was evaluated and statistical analyses were performed (P ≤ 0.05). Results. At 7 days, all materials induced an inflammatory reaction in the subcutaneous tissue adjacent to the implants.

A cross-sectional study was carried out among three groups of PHC personnel in the city of Kerman (Iran). Volunteer personnel completed a piloted questionnaire which included demographic data, some question regarding their knowledge about oral health, their duties and also their practice regarding public oral health. All data were analyzed using chi-square and Pearson correlation test. Results. One hundred and fifty-seven out of 225 eligible personnel participated in the study. Sixty percent were auxiliary health workers (Behvarz). All personnel had a good level of knowledge regarding oral health. Despite significant differences among the knowledge of the personnel toward oral health, there was no significant difference between their knowledge related to their duties regarding oral health. The auxiliary health worker group had a higher rate (45.6%) for better public oral health practice. Conclusion. The study showed the personnel have good knowledge of their duties regarding oral health.
