Palavras-chave students, 30.1% and 19.6% respectively, (p ≤ 0.001). The prevalence of symptoms of stress was 49.7% and students attending the fourth semester showed the highest levels of symptoms (p = 0.002). Conclusions: The conclusion is that Medical students at UFC have levels of stress similar to those reported in international studies.

Assessment Instruments for a Health-Related Quality of Life in DiabetesMellitus. the assessment of Health-related quality of Life (HrqoL) has been increasingly used to measure the overall impact of diseases in people's life. diabetes mellitus (dM) is a chronic disease associated with high morbidity, mortality, and HrqoL impairment in patients. In longitudinal studies, the psychosocial impact of dM predicts mortality. the objective of this review is to describe and to analyze the main instruments used for the HrqoL evaluation in patients with dM. generic instruments such, as the quality of Well-Being Scale (qWB), Medical Outcomes Study 36-item Short-Form Health Survey (SF-36), Euroqol (Eq-5d) and specific instruments as the diabetes care Profile (dcP), diabetes quality of Life Measure (dqOL), diabetes Impact Measurement Scales (dIMS), Appraisal of diabetes Scale (AdS), Audit of diabetes-dependent quality of Life (AddqoL), diabetes Health Profile (dHP-1 and dHP-18), questionnaire on Stress in Patients with diabetes-revised (qSd-r), WellBeing Enquiry goes diabetics (WEd), diabetes-Specific quality-of-life Scale

Background: Despite advancements in oral health policies, dental caries still a problem. The lack of parents/ caregiver's care regarding child's oral health, which characterizes neglect, may lead to a high prevalence of caries. Therefore, the objective of this study was to analyze the relation between dental caries and neglect in five year-old children.

Despite some studies correlating dental fluorosis (DF) and fluoride (F) concentration in dental enamel, no information is available about DF and dentin F concentration. Our objective was to determine the correlation between teeth F concentration and DF severity in unerupted human 3rd molars, and the correlation between dentin and enamel F concentrations in the same tooth. Ninety-nine 3rd molars were studied-53 from Fortaleza, Brazil (F water, 0.7 ppm), 22 from Toronto (1.0 ppm), and 24 from Montreal (0.2 ppm). DF severity was evaluated according to the Thylstrup-Fejerskov Index, while F concentration was analyzed by Instrumental Neutron Activation Analysis. DF severity varied between TF0 and TF4, while F concentration ranged between 39 and 550 ppm in enamel and 101 and 860 ppm in dentin. Our results showed correlation between dentin F concentration and DF (r(S) = 0.316, p = 0.001), but no correlation between enamel F concentration and DF (r(S) = 0.154, p = 0.133). No correlation was observed between dentin and enamel F concentrations in the same tooth (r(S) = 0.064, p = 0.536).
