13. Avaliação in vitro da terapia fotodinâmica sobre microrganismos cariogênicos presentes na saliva de crianças / In vitro evaluation of the photodynamic therapy effects on the cariogenic microrganisms in saliva of infants
The increase of bacterias resistance to conventional treatment resulted in the development of new therapeutic modalities for dental caries treatment and/or prevention. In this field, the use of photodynamic therapy (PDT) is suggested as an alternative for inactivation of patogenic microrganisms involved in the etiology of tooth decay. The aim of this study w

14. Estado nutricional associado à cÃrie dentÃria em escolares adolescentes na cidade do Recife
Introduction: Caries and overweight in adolescents are problems with major impact on health of the population. The overweight has been linked to the increase in consumption of refined carbohydrates, especially sugar, which are related to the prevalence of caries. The strategy of prevention and control of these diseases is the identification of common risk fa

15. O som da ablação do tecido dentinário com lasers de Érbio como possível parâmetro de mínima intervenção / The sound of dentinal tissue ablation with Erbium lasers as a possible parameter for minimal intervention
A evidência científica da cariologia atual vem apontando para a promoção de saúde bucal, técnicas preventivas, diagnóstico precoce da doença cárie e suas lesões nos elementos dentais, remineralização de lesões de cárie incipientes e a intervenção restauradora célere como procedimentos minimamente invasivos. Durante o ato de remoção de les�

16. Perfil epidemiológico de saúde bucal da população do parque indígena do Xingu, entre os anos de 2001 e 2006 / Conditions of Oral Health of the Park of Xingus Population, among 2001 and 2006.
There is a lack of information about the epidemiology of oral health conditions of the Indian population in Brazil. In general, available data are related to urban regions. Information about the epidemiology of oral health in the Xingu Indian Park (PIX) derive from surveys that employed different methodologies for collecting and analyzing the data, making it

17. Tratamento restaurador atraumÃtico (ART): avaliaÃÃo de um protocolo de atendimento em gestantes da rede pÃblica do municÃpio de Feira de Santana
The Atraumatic Restorative Treatment (ART) is a treatment alternative for the caries disease, which remains with high prevalence, and constitutes a serious public health problem. The ART consists in the removal of the carious tissue with manual instruments and later closing of its cavities with glass-ionomer cement (GIC). It is important to develop a health

18. Avaliação da saúde bucal e anomalias dentárias em pacientes tratados com leucemia na infância e adolescência
Objetivo: o objetivo deste estudo foi avaliar as condições de saúde bucal e a ocorrência de anomalias dentárias em crianças tratadas para leucemia linfoblástica aguda (LLA) no Serviço de Oncologia Pediátrica (SOP) do Hospital de Clínicas de Porto Alegre (HCPA), comparadas com um grupo crianças saudáveis. Amostra: foram selecionadas 56 crianças c

19. Prevalencia de carie e fluorose dentaria em escolares de 12 anos do Municipio de Paracambi-RJ e associações com variaveis socio-economicas / The prevalence of tooth decay and fluorosis among of twelve-year-old scholastic population in Paracambi City and associations with the social and economical variables
Os objetivos desse estudo foram: a) determinar por meio de um estudo epidemiológico transversal a prevalência de cárie e fluorose dentária em Paracambi, RJ, na população de escolares na faixa etária dos 12 anos; b) avaliar se há relação entre a experiência de cárie e prevalência e grau de fluorose nas crianças avaliadas e o nível socioeconômi

20. The analysis of the main index in oral health in the city of Campos dos Goytacazes ? RJ, Brazil / Analise dos principais indicadores em saude bucal no Municipio de Campos dos Goytacazes/RJ, Brasil
The objectives of this work were: 1) to analyze the information system in the oral helth of Campos dos Goytacazes (RJ) in 2004; 2) to compare the relation of IDH (Human Development Index) with the oral health in the cities of the north ?fluminense? in the state of Rio de Janeiro in 2004; 3) to verify the prevalence and severity of tooth decay, in schools and

21. Biochemical characterization and evaluation of virulence of a fructosyltransferase-deficient mutant of Streptococcus mutans V403.
The Streptococcus mutans extracellular fructosyltransferase (FTF) enzyme may play a role in the formation of dental caries by synthesizing a fructan polymer that serves as an extracellular storage polysaccharide. We sought to determine if an FTF-deficient strain of S. mutans was less virulent than wild-type cells in a rat animal model system. Cloned ftf gene

22. Competitive displacement of mutans streptococci and inhibition of tooth decay by Streptococcus salivarius TOVE-R.
The ability of Streptococcus salivarius TOVE-R to displace virulent representatives of the most prevalent human mutans streptococci from the teeth of rats, and thereby to inhibit caries, was studied. Streptococcus mutans 10449S- or Streptococcus sobrinus 6715-13WT-infected specific-pathogen-free rats consuming a high-sucrose diet were inoculated by TOVE-R. T

23. Near-infrared image-guided laser ablation of dental decay
Image-guided laser ablation systems are now feasible for dentistry with the recent development of nondestructive high-contrast imaging modalities such as near-IR (NIR) imaging and optical coherence tomography (OCT) that are capable of discriminating between sound and demineralized dental enamel at the early stages of development. Our objective is to demonst

24. Genome sequence of Streptococcus mutans UA159, a cariogenic dental pathogen
Streptococcus mutans is the leading cause of dental caries (tooth decay) worldwide and is considered to be the most cariogenic of all of the oral streptococci. The genome of S. mutans UA159, a serotype c strain, has been completely sequenced and is composed of 2,030,936 base pairs. It contains 1,963 ORFs, 63% of which have been assigned putative functions.
