Differential analysis of culturable and unculturable subgingival target microorganisms according to the stages of periodontitis.

Objectives: Culturable and unculturable microorganisms have been associated with periodontitis. Their differential proportions and composition have not been evaluated by their severity and complexity defined by stages in the 2018 AAP-EEP classification.

Methods: One hundred eighty subgingival biofilm samples were collected in Spain and Colombia from subjects categorized as health/gingivitis: periodontitis stages I/II periodontitis stages III/IV.

Placental Atopobiosis and Inflammatory Responses in Women With Adverse Pregnancy Outcomes.

The microbiome modulates inflammation at the fetal maternal interface on both term and preterm labor. Inflammophilic oral bacteria, such as , as well as urogenital microorganisms (UGM) could translocate to the placenta and activate immune mechanisms in decidual tissue that is associated with adverse pregnancy outcomes (APO). This study establishes the associations between the presence of microbes in the placenta and placental cytokine patterns in women who presented APO, e.

Periodontal condition is associated with adverse perinatal outcomes and premature rupture of membranes in low-income pregnant women in Bogota, Colombia: a case-control study.

To assess the periodontal condition as a factor associated with adverse perinatal outcomes, premature rupture of membranes (PRM), and preeclampsia in low-income pregnant women treated at public hospitals in Bogotá, Colombia. Pregnant women with preterm birth (PTB) and low birth weight (LBW) or both conditions ( = 107/428), or only PTB ( = 73/292) or LBW ( = 74/296) or with PRM ( = 98/392) or preeclampsia ( = 76/304) in a ratio of four controls for each case, coming from three hospitals of the public Northern Network of Bogotá, Colombia were studied. Sociodemographic, perinatal adverse outcome history, antenatal care, chronic infections, periodontal condition, threatened abortion, bleeding in the second half of pregnancy, oligohydramnios, diabetes, gestational diabetes, alcohol consumption, hypertension, smoking, alcohol during pregnancy were determined.

Microbiome and Microbial Biofilm Profiles of Peri-Implantitis: A Systematic Review.

Background: This systematic review assesses microbiologic profiles of peri-implantitis, periodontitis, and healthy implants based on studies that evaluated microbial biofilms and entire microbiomes to establish their similarities and differences.

Methods: The Medical Literature Analysis and Retrieval System Online via PubMed, Excerpta Medica Database, and Cochrane Central Register of Controlled Trials, were searched without language restrictions through July 30, 2016. Observational studies that evaluated microbial profiles or entire microbiomes of peri-implantitis compared with healthy implants or periodontitis were considered eligible for inclusion.
