Does subgingival bacterial colonization differ between implants and teeth? A systematic review

Braz. oral res. (Online); 33 (supl.1), 2019
Abstract The aim was of this study was to determine the current weight of evidence for the existence of specific differences between the microbiota of healthy teeth and healthy implants, or of teeth with periodontitis and implants with peri-implantitis. A systematic review was conducted according to the ...

Frequency of Porphyromonas gingivalis fimA in smokers and nonsmokers after periodontal therapy

J. appl. oral sci; 27 (), 2019
Abstract Porphyromonas gingivalis is one of the most important Gram-negative anaerobe bacteria involved in the pathogenesis of periodontitis. P. gingivalis has an arsenal of specialized virulence factors that contribute to its pathogenicity. Among them, fimbriae play a role in the initial attachment and ...

Effects of chlorhexidine preprocedural rinse on bacteremia in periodontal patients: a randomized clinical trial

J. appl. oral sci; 25 (6), 2017
Abstract Objective: Single dose of systemic antibiotics and short-term use of mouthwashes reduce bacteremia. However, the effects of a single dose of preprocedural rinse are still controversial. This study evaluated, in periodontally diseased patients, the effects of a pre-procedural mouth rinse on indu...

Different engagement of TLR2 and TLR4 in Porphyromonas gingivalis vs. ligature-induced periodontal bone loss

Abstract This study was conducted to investigate the roles of different Toll-like receptor (TLR) signaling in Porphyromonas gingivalis (P. gingivalis)-induced and ligature-induced experimental periodontal bone resorption in mice. Wild-type (WT), TLR2 knockout (KO), TLR4KO, and TLR2&4 KO mice with C57...

Frequency of periodontal pathogens and Helicobacter pylori in the mouths and stomachs of obese individuals submitted to bariatric surgery: a cross-sectional study

J. appl. oral sci; 24 (3), 2016
ABSTRACT Objectives This cross-sectional study compared the frequency of oral periodontopathogens and H. pylori in the mouths and stomachs of obese individuals with or without periodontitis submitted to bariatric surgery. Material and Methods One hundred and fifty-four men and women aged 18-65 were c...

Lactobacillus rhamnosus could inhibit Porphyromonas gingivalis derived CXCL8 attenuation

J. appl. oral sci; 24 (1), 2016
ABSTRACT An increasing body of evidence suggests that the use of probiotic bacteria is a promising intervention approach for the treatment of inflammatory diseases with a polymicrobial etiology. P. gingivalis has been noted to have a different way of interacting with the innate immune response of the hos...

Avaliação clínica e microbiológica relacionada à doença periodontal em pacientes com lúpus eritematoso sistêmico

O lúpus eritematoso sistêmico (LES) é uma doença autoimune caracterizada por hiperatividade imunológica crônica pela ação de autoanticorpos que afetam diversos órgãos. Embora o uso crônico de imunossupressores predisponha o paciente a infecções, poucas pesquisas avaliaram uma possível assoc...

Effect of Resveratrol on periodontal pathogens during experimental periodontitis in rats

Braz. oral res. (Online); 30 (1), 2016
Abstract The objective of this study was to investigate the antibacterial effect of resveratrol against putative periodontal pathogens during the progression of experimental periodontitis in rats. Periodontitis was induced in rats in one of the first molars chosen to receive a ligature. Animals were assi...

Longitudinal study on clinical and microbial analysis of periodontal status in pregnancy

Braz. oral res. (Online); 30 (1), 2016
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 pregna...
