1. Role of Candida albicans on enamel demineralization and on acidogenic potential of Streptococcus mutans in vitro biofilms
Abstract There is growing evidence that C. albicans is associated with dental caries, but its role on caries development needs to be better clarified. Objective: To evaluate at the hard tissue level the effect of C. albicans on the cariogenic potential of S. mutans biofilms focusing on the mineral profile of induced carious lesions. This study also aimed to

2. Enamel and dentine demineralization by a combination of starch and sucrose in a biofilm – caries model
Abstract Sucrose is the most cariogenic dietary carbohydrate and starch is considered non-cariogenic for enamel and moderately cariogenic for dentine. However, the cariogenicity of the combination of starch and sucrose remains unclear. The aim of this study was to evaluate the effect of this combination on Streptococcus mutans biofilm composition and enamel

3. IDENTIFICAÇÃO DE COMPOSTOS ORGÂNICOS EM LIXIVIADO DE ATERRO SANITÁRIO MUNICIPAL POR CROMATOGRAFIA GASOSA ACOPLADA A ESPECTROMETRIA DE MASSAS
The organic compounds present in leachate can contaminate soil, superficial and underground water, and the majority is considered harmful to the environment and human health. The objective of this study was to identify organic compounds present in landfill leachate located in Maringá-PR by gas chromatography coupled to mass spectrometry (GC-MS). The raw

4. Anionic variation of diets on bone characteristics of broilers at 7 and 14 days of age
The objective of this study was to evaluate the chemical composition and bone strength of the tibiotarsus of broilers at 7 and 14 days of age. Bone percentages of collagenous protein (CPr), non-collagenous protein (NCPr) and minerals (calcium, phosphorus, potassium and sodium) were determined. The experiment utilized 650 male Cobb chicks at one day of age, f

5. Reduced salivary flow and colonization by mutans streptococci in children with Down syndrome
OBJECTIVES: Although individuals with Down syndrome have considerable oral disease, the prevalence of dental caries in this group is low. The present study aimed to compare known risk factors for dental caries development in children with Down syndrome and a matched population (siblings). In both populations, the number of acidogenic microorganisms, such as

6. ProduÃÃo de Ãcidos graxos volÃteis por biodigestÃo anaerÃbia da manipueira / Production of volatile fatty acids by anaerobic biodigestion of manipueira
The cultivation of cassava extends throughout Brazil because of its excellent adaptation to different soils and climatic conditions. Our country occupies the second position at the worldwide ranking in cultivating this plant (15% of the world production). The industrial processing of cassava generates a liquid waste, the so called manipueira, considered as a

7. AVALIAÇÃO DO POTENCIAL ACIDOGÊNICO DO LEITE MATERNO EM CRIANÇAS COM DIFERENTES EXPERIÊNCIAS DE CÁRIE / ASSESSMENT OF POTENTIAL ACIDOGENIC OF BREASTMILK CHILDREN WITH DIFFERENT EXPERIENCES OF CARIES
Given that breastfeeding after 1 year old has been reported by some studies as a risk factor for early childhood caries (ECC), and it is unknown whether breast milk is metabolized in a structured oral biofilm in children with ECC leading to pH drops, the objective of this study was to evaluate the milk acidogenic potential in oral biofilm of non-exclusive in

8. Proposta de metodologia para determinação da atividade hidrogênica específica
Hydrogen production by fermentation process is influenced by the concentration and characteristics of organic substrate, the effluent pH value and biomass concentration. The determination of specific hydrogenic activity of organic substrates and biomass can be a tool to analyze the hydrogen volume produced during the fermentation, the volatile fatty acids pr

9. Evaluation of phenotypic traits of cariogenicity of Strptococcus Mutans genotypes isolated from dental biofilm / Avaliação de caracteristicas fenotipicas de cariogenicidade de genotipos de Strptococcus Mutans isolados de biofilme dental
Mutans streptococci, mainly Streptococcus mutans, are considered as the main microorganisms related to dental caries. These microorganisms are present in oral cavity as distinct genotypes, which may show distinct phenotypic traits. In this context, it was evaluated the S. mutans genotypic diversity in dental biofilm formed in vivo and in situ during 3 days u

10. The cariogenic dental biofilm: good, bad or just something to control?
This paper discusses the role of dental biofilm and adjunctive therapies in the management of dental caries. Dental biofilm is a site of bacterial proliferation and growth, in addition to being a location of acid production. It also serves as a reservoir for calcium exchange between the tooth and saliva. The salivary pellicle, a protein-rich biofilm layer, r

11. Produção de hidrogênio e ácidos orgânicos por fermentação acidogênica em reator anaeróbio de leito fluidificado / Hydrogen and volatile fatty acids production by acidogenic fermentation in anaerobic fluidized bed reactor
A matéria orgânica presente nas águas residuárias representa uma matéria prima barata para integrar o processo de digestão anaeróbia e gerar fontes de energia alternativas, como o hidrogênio. O hidrogênio pode substituir os combustíveis fósseis não renováveis e diminuir as emissões de gases do efeito estufa responsável por grande parte da muda

12. Action of photosensitizers dyes in homogeneous and liposomal microheterogeneous medium to control Streptococcus mutans growing / Ação de corantes fotossensíveis em meio homogêneo e micro heterogêneo de lipossomos no controle do crescimento de Streptococcus mutans
Unbalance in the development of the mouth macrobiota can originate some pathologies, dental cavity being among them - a chronic disease - contagious, of multifactorial etiology, but extremely related to the Streptococcus mutans bacteria, which, through its fermentative metabolism, destroys tooth mineralized structures. Besides that, the increase in resistanc
