Inhibitory effect of reduced graphene oxide-silver nanocomposite on progression of artificial enamel caries

J. appl. oral sci; 27 (), 2019
Abstract The use of antimicrobial agents is an efficient method to prevent dental caries. Also, nanometric antibacterial agents with wide antibacterial spectrum and strong antibacterial effects can be applied for prevention of dental caries. Objectives: The aim of this study was to evaluate the inhibito...

Comparison between static and semi-dynamic models for microcosm biofilm formation on dentin

J. appl. oral sci; 27 (), 2019
Abstract Microcosm biofilm has been applied to induce carious lesions in dentin. However, no study has been done to compare the impact of the type of model for providing nutrients to microcosm biofilm formation on dentin. Objective This study compared the performance of two kinds of models (static and s...

Chronic prostatitis alters the prostatic microenvironment and accelerates preneoplastic lesions in C57BL/6 mice

Biol. Res; 52 (), 2019
BACKGROUND: Chronic prostatitis has been supposed to be associated with preneoplastic lesions and cancer development. The objective of this study was to examine how chronic inflammation results in a prostatic microenvironment and gene mutation in C57BL/6 mice. METHODS: Immune and bacterial prostatitis mo...

Role of extracellular DNA in Enterococcus faecalis biofilm formation and its susceptibility to sodium hypochlorite

J. appl. oral sci; 27 (), 2019
Abstract Objective This study investigated the role of extracellular deoxyribonucleic acid (eDNA) on Enterococcus faecalis ( E. faecalis ) biofilm and the susceptibility of E. faecalis to sodium hypochlorite (NaOCl). Methodology E. faecalis biofilm was formed in bovine tooth specimens and the biofilm ...

Effect of hydroalcoholic extract of Myracrodruon urundeuva All. and Qualea grandiflora Mart. leaves on the viability and activity of microcosm biofilm and on enamel demineralization

J. appl. oral sci; 27 (), 2019
Abstract Objectives: The aim of this study was to assess the effect of Myracrodruon urundeuva All. and Qualea grandiflora Mart. leaves hydroalcoholic extracts on viability and metabolism of a microcosm biofilm and on enamel demineralization prevention. Methodology: Microcosm biofilm was produced on bov...

Comparison of rRNA-based reverse transcription PCR and rDNA-based PCR for the detection of streptococci in root canal infections

J. appl. oral sci; 27 (), 2019
Abstract Objective The rDNA-based method is unable to distinguish between alive and dead cells. Alternatively, bacterial viability can be assessed by molecular methods based on ribosomal RNA (rRNA). Therefore, this study aimed to detect viable streptococci in root canal samples using rRNA-based reverse...

Relationship between acetaldehyde concentration in mouth air and characteristics of microbiota of tongue dorsum in Japanese healthy adults: a cross-sectional study

J. appl. oral sci; 27 (), 2019
Abstract Acetaldehyde, associated with consumption of alcoholic beverages, is known to be a carcinogen and to be related to the tongue dorsum. Objective The aim of this study was to investigate the relationship between acetaldehyde concentration in mouth air and bacterial characteristics on the tongue ...

Is there a relation between helybacter pylori and intestinal metaplasia in short column epitelization up to 10 mm in the distal esophagus?

ABCD (São Paulo, Impr.); 32 (4), 2019
ABSTRAT Background: The presence of intestinal metaplasia in the distal esophagus (Barrett's esophagus) is an important precursor of adenocarcinoma. Knowledge of the risk factors and the process by which the Barrett develops is very important and Helicobacter pylori (HP) can contribute to this developm...

Calcificación heterotópica miocárdica y pericarditis constrictiva en contexto de sepsis por a propósito de un caso

Rev. chil. anest; 48 (3), 2019
We report the case of a 21 years old woman without history of cardiovascular disease, who after her first euthocic delivery, did complain of genital infection of white parts complicated by pneumonia and pyothorax, isolating Streptococcus pyogenes, requiring intensive care, inotropic and vasoactive medica...

Chlamydophila pneumoniae infection is not associated with primary biliary cholangitis

Gastroenterol. latinoam; 30 (2), 2019
ANTECEDENTES: La colangitis biliar primaria (CBP) es una enfermedad hepática inflamatoria crónica colestásica de causa desconocida. Varios patógenos virales y bacterianos han sido propuestos como factores que podrían gatillar una respuesta inmune por mimetismo molecular, o directamente estar relacio...
