1. Chemical and structural composition of black pigmented supragingival biofilm of bovines with periodontitis
RESUMO: A periodontite bovina é uma infecção multifatorial associada primariamente à microbiota potencialmente patogênica presente no biofilme bucal. Biofilmes são estruturas organizadas, nas quais os constituintes convivem em simbiose, descritos em outras espécies como um fator predisponente à periodontite. O objetivo do presente estudo foi caracter

2. Anadenanthera Colubrina vell Brenan: anti-Candida and antibiofilm activities, toxicity and therapeutical action
Abstract: We evaluated the antifungal and antibiofilm potential of the hydroalcoholic extract of bark from Anadenanthera colubrina (vell.) Brenan, known as Angico, against Candida spp. Antifungal activity was evaluated using the microdilution technique through the Minimum Inhibitory and Fungicide Concentrations (MIC and MFC). The antibiofilm potential was te

3. Effect of γ-lactones and γ-lactams compounds on Streptococcus mutans biofilms
Abstract Considering oral diseases, antibiofilm compounds can decrease the accumulation of pathogenic species such as Streptococcus mutans at micro-areas of teeth, dental restorations or implant-supported prostheses. Objective To assess the effect of thirteen different novel lactam-based compounds on the inhibition of S. mutans biofilm formation. Material

4. Prevalence and Sensitivity of Bacilli and Pseudomonas in the Newborn’s Oral Cavity
Abstract The aim of this study was to isolate Enterobacteria and Pseudomonas from the oral cavity of hospitalized newborns (NB) and determine their prevalence and the sensitivity profile to most commonly used antibiotics for this age group. Samples from the oral cavity of NB from 24 to 48 h age were collected using swabs. The samples were inoculated on MacCo

5. Influence of iron deprivation on virulence traits of mycobacteria
ABSTRACT Novel strategies to combat the ever increasing burden of drug resistance in Mycobacterium tuberculosis (MTB) causing tuberculosis (TB) remains a global concern. The ability of MTB to sense and adapt to restricted iron conditions in the hostile environment is essential for their survival and confers the basis of their success as dreadful pathogen. Th

6. Effects of probiotic fermented milk on biofilms, oral microbiota, and enamel
The aim of this study was to evaluate in vitro and in vivo the effects of 2 brands of probiotic fermented milk on biofilms, oral microbiota, and enamel. For the in situ experiment, ten volunteers wore palatine devices containing four blocks of bovine dental enamel over 3 phases, during which 20% sucrose solution, Yakult® (Treatment A), and Batavito® (Treat

7. Pimenta pseudocaryophyllus inhibits virulence factors and promotes metabolic changes in Candidayeast
IntroductionThis is the first study to examine the in vitrosusceptibility and the expression of virulence factors in Candida species in the presence of Pimenta pseudocaryophyllus (Gomes) L.R. Landrum (Myrtaceae), a Brazilian plant known as paucravo. Additionally, the mechanisms of action of the crude ethanol extract and the ethyl acetate and aqueous fraction

8. Effect of cariogenic challenge on the stability of dentin bonds
Objective: The oral environment is subject to biofilm accumulation and cariogenic challenge, and few studies exist on the effect of these factors on the bond strength of adhesive systems. The aim of this study was to test if the exposure of adhesive interfaces to cariogenic challenge under biofilm accumulation could promote higher degradation than the expos

9. Antimicrobial mouthrinse use as an adjunct method in peri-implant biofilm control
Great possibilities for oral rehabilitation emerged as a result of scientific consolidation, as well as a large number of dental implant applications. Along with implants appeared diseases such as mucositis and peri-implantitis, requiring management through several strategies applied at different stages. Biofilm accumulation is associated with clinical signs

10. Is there an association between periodontal pathogens colonization and the frequency of some specific serotype of Aggregatibacter actinomycetemcomitans? / Existe uma associação entre a colonização de patógenos periodontais e a frequência de sorotipos específicos de aggregatibacter actinomycetemcomitans?
Aggregatibacter actinomycetemcomitans is a gram-negative, facultative anaerobic coccobacillus bacterium that colonizes the human oral cavity. Regarding the bacterial consortium found into biofilms, previous studies have suggested that the occurrence of particular serotypes of A. actinomycetemcomitans may be related to other oral microorganisms. Interestingly

11. AVALIAÃÃO DO POTENCIAL ANTIMICROBIANO DE LECTINAS E OUTRAS SUBSTÃNCIAS NATURAIS FRENTE A BACTÃRIAS ORAIS / ANTIMICROBIAL POTENCIAL ANALYSIS OF LECTINS AND OTHER NATURAL SUBSTANCES AGAINST ORAL BACTERIA
Os biofilmes sÃo uma forma mais resistente de vida microbiana comparada à forma planctÃnica, em vida livre. Essa resistÃncia està diretamente relacionada Ãs caracterÃsticas naturais de sobrevivÃncia das cÃlulas microbianas vivendo nesse tipo de comunidade. A doenÃa cÃrie capaz de acometer os tecidos dentais està diretamente relacionada com a form

12. Influência das proteínas salivares e plasmáticas no desenvolvimento de biofilmes de Candida albicans / The influence of salivary and plasmatic proteins on the development of Candida albicans biofilms
The development of Candida albicans biofilms may be mediated by a differential expression of proteic ligand sites in the acquired pellicle formed onto the oral prosthesis surfaces. Therefore, the main objective of this study was to evaluate the influence of salivary and plasmatic-derived proteins on the development of C. albicans biofilms. In the first chapt
