1. In Vitro Homeostasis of Rat Oral Epithelial Cell Cultures Following Withdrawal of Periodontal Pathogens
Resumo A inflamação dos tecidos periodontais é a consequência da interação entre patógenos periodontais e o sistema imunológico. Isso está associado ao aumento da expressão de citocinas inflamatórias, que podem exercer efeito destrutivo nos tecidos periodontais quando liberadas por um longo período. O objetivo deste estudo foi rastrear cronologic

2. Prevalence and Molecular Analysis of Novel Newly Identified Periodontal Pathogens in Subgingival Plaque Samples of Saudi Patients with Chronic Periodontitis
Abstract Objective: To evaluate the prevalence of novel newly identified periodontal pathogenic strains in subgingival plaque samples and relate it with bleeding on probing, probing pocket depth and age. Material and Methods: 268 chronic periodontitis patients with a mean age of 46.0 ± 6.0 years were included. The following microorganisms were evaluated:

3. Subgingival bacterial microbiota associated with ovine periodontitis
RESUMO: Periodontite é a resposta inflamatória de um hospedeiro suscetível causada por complexa microbiota, composta predominantemente por bactérias anaeróbias Gram-negativas. Com o objetivo de caracterizar a microbiota bacteriana subgengival associada à periodontite ovina foi realizada a reação em cadeia da polimerase (PCR) de amostras de biofilme s

4. Regulation of ghrelin receptor by microbial and inflammatory signals in human osteoblasts
Abstract: Recently, it has been suggested that the anti-inflammatory hormone ghrelin (GHRL) and its receptor GHS-R may play a pivotal role in periodontal health and diseases. However, their exact regulation and effects in periodontitis are not known. The aim of this in-vitro study was to investigate the effect of microbial and inflammatory insults on the GHS

5. Efficacy of virginiamycin for the control of periodontal disease in calves
RESUMO: As doenças periodontais são processos infecciosos multifatoriais causados por complexos de micro-organismos, que provocam danos à saúde, produção e ao bem-estar animal. O objetivo do presente estudo foi o de avaliar a eficácia da virginiamicina na prevenção e controle de duas formas de doença periodontal; a gengivite e a gengivite necrosant

6. Evaluation of chemokines and receptors in gnotobiotic root canal infection by F. nucleatum and E. faecalis
Abstract The present study aims to evaluate the longitudinal effects of induced experimental infections in gnotoxenic animals on the expression of inflammatory chemokines and their receptors in periradicular tissues. The null hypothesis tested was that Enterococcus faecalis and Fusobacterium nucleatum had no effect on CCR5, CCL5, CXCL10, CCL2/MCP-1, CXCR2 an

7. Two mechanisms of oral malodor inhibition by zinc ions
Abstract Objectives The aim of this study was to reveal the mechanisms by which zinc ions inhibit oral malodor. Material and Methods The direct binding of zinc ions to gaseous hydrogen sulfide (H2S) was assessed in comparison with other metal ions. Nine metal chlorides and six metal acetates were examined. To understand the strength of H2S volatilization i

8. Microbiological, lipid and immunological profiles in children with gingivitis and type 1 diabetes mellitus
Abstract Objective The aim of this study was to compare the prevalence of periodontal pathogens, systemic inflammatory mediators and lipid profiles in type 1 diabetes children (DM) with those observed in children without diabetes (NDM), both with gingivitis. Material and methods Twenty-four DM children and twenty-seven NDM controls were evaluated. The pe

9. Influence of glycemic control on the levels of subgingival periodontal pathogens in patients with generalized chronic periodontitis and type 2 diabetes
Abstract Objective This study evaluated the influence of glycemic control on the levels and frequency of subgingival periodontal pathogens in patients with type 2 diabetes mellitus (DM) and generalized chronic periodontitis (ChP). Material and Methods Fifty-six patients with generalized ChP and type 2 DM were assigned according to the levels of glycated

10. Bacterial diversity of symptomatic primary endodontic infection by clonal analysis
Abstract The aim of this study was to explore the bacterial diversity of 10 root canals with acute apical abscess using clonal analysis. Samples were collected from 10 patients and submitted to bacterial DNA isolation, 16S rRNA gene amplification, cloning, and sequencing. A bacterial genomic library was constructed and bacterial diversity was estimated. The

11. Murine Experimental Root Canal Infection: Cytokine Expression in Response to F. nucleatum and E. faecalis
Resumo O objetivo deste trabalho foi avaliar a expressão gênica de citocinas pró-inflamatórias (RANKL, TNF-a e IFN-g) e regulatórias (TGF-b e IL-10) em resposta à infecção experimental por Fusobacterium nucleatum (ATCC 10953) e Enterococcus faecalis (ATCC 19433) como mono-infecção ou em bi-associação. F. nucleatum e E. faecalis foram inoculados n

12. Longitudinal study on clinical and microbial analysis of periodontal status in pregnancy
Abstract This study was aimed to provide a longitudinal overview of the subgingival bacterial microbiome using fluorescence in situ hybridization (FISH) technique, in women in the second trimester of pregnancy (between 14 and 24 weeks), and 48 h and 8 weeks postpartum. Of 31 women evaluated during pregnancy, 24 returned for the 48-h and 18 for their 8-week e
