- Case report of a dilated odontome in the posterior mandiblePublication . Almeida, Bruno; Silva, António; Pereira, Miguel; Silva, Mariana; Nunes, StephanieIntroduction Dens invaginatus (dens in dente) is a developmental malformation resulting from an invagination of enamel organ into the dental papilla, beginning at the crown and sometimes extending into the root before calcification occurs. Dilated odontome is the most extreme form of dens invaginatus and it is extremely rare in the posterior mandible. Presentation of case A 47 years old female patient with occasional episodes of diffuse pain and discomfort in the left posterior mandibular region. The extra-oral examination showed slight facial asymmetry. Panoramic and intra-oral X-rays show an intraosseous circular formation with radiopaque external limits and radiolucent interior. Discussion Computerized tomography scan reveals the bone integrity around the formation, as well as the independence of the neuro-vascular structures of the region. The most likely diagnostic option was dilated odontome. The enucleation procedure was carried out, and the fragments were sent to histopathological examination that revealed a diagnosis consistent with a dilated odontome. Conclusion In this case, the conservative surgical approach after planning was effective and predictable in the treatment of the pathology and patient symptoms without major complications.

- Dental caries: a reviewPublication . Veiga, Nélio Jorge; Aires, Daniela; Douglas, Filipa; Pereira, Margarida; Vaz, Ana; Rama, Liliana; Silva, Mariana; Miranda, Vanessa; Pereira, Francisco; Vidal, Beatriz; Plaza, João; Bexiga, Filipantroduction: Dental caries is the most prevalent chronic disease worldwide. It’s an infectious disease characterized by a multifactorial etiology and slow evolution that leads to the destruction of dental hard tissues. The implementation of preventive measures, the need of investing in education for the correct maintenance measures of oral health, associated with preventive and continuos medical and dental care, are key to the awareness of populations of its existence and to the decline of its prevalence. Throughout this article we intend to review some important aspects about dental caries and the main etiological factors envolved so that health professionals can intervene in the treatment and prevention of diseases. Materials and Methods: To carry out this review article the search strategies included electronic databases, such as Pubmed, Cochrane Library and Science Direct, reference lists of articles, and selected textbooks. Articles and textbooks used in this study were mainly reached by using the following keywords: “oral health”, “dental caries”, “etiological factors”, “risk factors”, “primary dental prevention”. Selection criteria included articles published from 1990 to the present year of 2016 that described the definition, etiology and other characteristics associated with the disease dental caries. At the end of the search, 16 scientific articles were selected. Results: Dental caries is a disease that develops through gradual complex biological interactions of acidogenic bacteria, fermentable carbohydrates and host factors such as the teeth and saliva, during time. The disease developes due to multifactorial aspects, since biological to social aspects that the oral health professional should be aware of. Discussion: The implementation of preventive measures, the need of investing in education for the correct maintenance measures of oral health, associated with preventive and continuos medical and dental care, are key for the awareness of populations of its existence and contribute for the decrease of the prevalence of oral diseases. Conclusions: Dental caries should be seen as a fairly common condition that can greatly affect the health and quality of life of patients, so it is extremely important to increase the knowledge towards their mechanisms, focusing on prevention and the correct therapeutic approach. However, it is necessary to be aware of the hard work ahead in the future related with education and oral health promotion.
- Eating out of home in Portugal: characterization and effects on dietary intakePublication . Silva, Mariana; Rodrigues, Sara S.P.; Correia, Daniela; Rei, Mariana; Severo, Milton; Costa, Ana Isabel A.; Torres, Duarte; Lopes, CarlaThis cross-sectional study aims to describe and compare energy, nutrient intake, and food consumption according to eating location and by age groups using data from the National Food, Nutrition and Physical Activity Survey (IAN-AF 2015/2016). Dietary intake was estimated by two non-consecutive days of food diaries (children)/24-hour recalls (other age groups) and four eating location categories were defined according to the proportion of meals consumed at out of home locations: Home (at least 80% of meals at home), Other Homes, School or Work and Restaurants and Other Places. The majority of meals (69.1%) were consumed at home. Meals were also often taken at school by children and adolescents, and in restaurants and similar outlets by adults and elderly. Children and adolescents in the School or Work category ate more fruit, vegetables and pulses and cereals and starchy tubers, whereas adults in this category ate more red and processed meats, sugar sweetened beverages and sweets. Compared to Home category, Restaurants and Other Places was associated with worse diet adequacies among children (β=-1.0; 95%CI=-2.0,-0.04), adolescents: (β=-2.4; 95%CI=-3.2,-1.5) and adults (β=-1.3; 95%CI=-1.6,-1.0) reflecting higher intakes of energy, fat, trans and saturated fatty acids, and sodium. The elderly consumed more free sugars and fat when eating out of home in general. Overall, findings reflect important variation in nutrient profiles by eating location, with meals taken at school or work contributing to higher consumption of nutrient-dense foods and those taken in restaurants and other similar settings implying higher consumption of energy-dense foods.
