This study presents a literature review which shows the nutritional, medicinal and antioxidant importance of mushrooms. In this research, the main antioxidant compounds of mushrooms, such as phenolic acids, flavonoids and tocopherols, as well as their mechanisms of action were described. The main in vitro methods used for evaluation of the antioxidant activity of these compounds were approached. The influences from the solvent polarity and the kind of extraction in the acquisition of the antioxidant compounds were also discussed. It was possible to conclude that mushrooms are a source of carbohydrates, proteins and minerals, thus presenting nutritional properties. The functional and medicinal properties are attributed to glucans, besides being excellent sources of natural antioxidants. Regarding the extraction process, it was noticed that the solvent polarity used in the extraction process is determinant in the obtainment of antioxidant compounds.

The knowledge of risk of carried during pregnant is essential for an appropriate treatment using educational and preventives actions to mother for a good care of their oral health and that of children. The main objective of present retrospective study was to identify the risk of caries of pregnants (aged 15-44, mean= 25 years) came to clinic of Preventive Odontology of Araraquara-UNSEP from 1999 to 2007, using 166 medical records obtained by the third pregraduate year students, following the pre-established guidelines. The information collected includes: classification of caries risk diagnosis, pregnancy trimester, carbohydrates ingestion (between or during foods), dental plaques (O'Leary's plaque control registry) and the number of teeth with caries. The statistical analysis used the Chi2 and ANOVA tests. Most of patients showed a 25 % or more of teeth surfaces with dental plaques (92.1 %) and carbohydrates consumption among foods (89.2 %). The mean (SD) of carried and restores teeth was of 7.9 (5.1) and 4.0 (3.4), respectively and the posterior teeth were the more involved by caries/restorations. As regards the diagnosis of caries risk, classification of high risk was observed in the 38.5 % of pregnants, moderate in the 47.6 %) and low in the 13.9 %. There was a statistically significant association (p= 0.001) between the carbohydrates consumption and the diagnosis of caries risk. The plaque's rate was similar in the different trimesters of pregnancy (f= 0.223; p= 0.803). The caries risk of most pregnant women was high or moderate and it was associated with the consumption of carbohydrates.
