Micronuclei (MN) originate from chromosome fragments or whole chromosomes that lag behind at anaphase during cell division can occur due to excessive exposure to harmful agents, defects in mitosis and / or DNA repair process. The study evaluated the frequency of micronuclei in cytological samples after daily use of alcohol -based mouthwash mouth in smokers and non-smokers. We assessed 30 subjects, aged between 17-42 years and established as exclusion criteria: alcohol consumption; periodontal disease; systemic diseases that may interfere with the integrity of the oral mucosa; individuals with medical or pharmacological history that affect the performance of the study, family history of malignancies. For smokers the inclusion criterion was a minimum consumption of 20 cigarettes / day, and the contrast required for non-smokers. The sample was divided into 02 experimental groups: Group 1 Smokers and Group 2 Non-Smokers, both groups performed mouthwash (alcohol 21,6%) with Listerine® Defense of Teeth and Gums for 04 weeks cytological collection were performed on buccal mucosa and portion median border of the tongue, one for initial, week 0 control, and subsequent three weeks with continued use of mouthwash. The collected material was stained by specific staining Feulgen / Fast Green. The analysis of 3000 cells / individual was performed by light microscopy statistics used Kruskal- Wallis and Mann-Whitney tests for frequency MN. The frequency of micronuclei in buccal mucosa was 1.6 ± 1.75 and 1.46 ± 2.06 for the site language to Group 1 Smokers of showing a slight increase compared with Group 2 Non-smoking, which showed a variation of 1.2 ± 1.53 for the buccal mucosa site and 0.86 ± 1.41 for the site language. However, this difference was not statistically significant. The results suggest that alcohol-based mouthwash tested is not an inducer of genotoxic changes, thus not changing the frequency...

Congenital toxoplasmosis is a serious public health case, for it causes irreversible damage to the embryo/fetus, which may cause its death. The identification and the care to pregnant women with suspect acute toxoplasmosis (IgM+) is performed in prenatal monitoring. This study aimed to measure the incidence and know the profile of positive pregnant women for toxoplasmosis in a Basic Health Unit (BHU) in Matão - SP, between the years 2011 to 2013. This is a retrospective descriptive study, from the medical records of pregnant women attended. The project was approved by the Municipal Departament of Health and BHU was chosen along the Municipal Epidemiological Surveillance. From 2011 to 2013, 189 women began prenatal care in the unit, an annual median of 71(±26.91), of which 17 (8.99%) were positive for the serological test indicative of acute phase (IgM+). The distribution over the trial period was: four cases in 2011, twelve cases in 2012 and one in 2013. Pregnant women IgM positive for toxoplasmosis attend by BHU were: age 24(±5.47) years; color: equally distributed among white, black and brown; as the number of pregnancies: multiparous (2±0.97), most of them with a cesarean delivery as obstetric history and possessed no other risk factors associated with pregnancy (94.12%); gave entrance at BHU with 13.65(±7.35) weeks of gestation and had a median of 5(±2.36) consultation on their prenatal care. The examination for toxoplasmosis was requested as recommended by the Health Ministry (HM) and the medication prescribed was Roxamicina® - spiramycin, as soon as the test results (IgM+) arrived. Of the 17 pregnant women, only 10 completed the pre-natal at BHU - attendance at the postpartum consult (58.8%). Of these, the deliveries were vaginal (55.55%), made preterm with 36.5 weeks of gestation at the Municipal Hospital. The babies were born alive (100%) with the weight of 2.68(±0.77) Kg and required special care hospital scope. From the ...

The aim of this study was to evaluate the effect of the working angle variation of the magnetoestritive ultrasonic (MU) and air polishing devices (APD) on the roughness and wear of dental root. Fifty bovine incisive teeth were used in this study. The proximal surfaces of the teeth were divided in three regions: coronal, median, and an apical. The coronal region was treated with a manual scaler, the apical region was treated with APD or with a MU and the medium region was maintained untreated to serve as a control. The teeth were divided in 11 groups according to the treatment applied: MU-0º; MU-30º; MU-45º; MU-60º; MU-90º; AP-0º; AP-30º; AP-45º; AP-60º; AP-90º; MS: manual scaler. To the statistical analysis, data submitted to the Anova and Tukey's test (p < 0.05). The manual curette promotes less roughness and higher tooth wear in comparison with the both ultrasonic and air polishing devices (p < 0.05). The angles of 45º, 60º and 90º caused higher rate of tooth wear and roughness when the MU was used (p < 0.05), while the angle of 90° caused a higher tooth wear than the angle of 30° when the APD was used (p < 0.05). The working angle variation influenced the tooth wear and roughness promoted by MU, whereas when using APD, the working angle variation influenced only the tooth wear.
