Exploring links between oral health and infective endocarditis.

Infective endocarditis (IE) is a bacterial infection of the heart's inner lining. A low incidence rate combined with a high mortality rate mean that IE can be difficult to treat effectively. There is currently substantial evidence supporting a link between oral health and IE with the oral microbiome impacting various aspects of IE, including pathogenesis, diagnosis, treatment, and mortality rates.

The promise and challenges of genomics-informed periodontal disease diagnoses.

Recent advances in human genomics and the advent of molecular medicine have catapulted our ability to characterize human and health and disease. Scientists and healthcare practitioners can now leverage information on genetic variation and gene expression at the tissue or even individual cell level, and an enormous potential exists to refine diagnostic categories, assess risk in unaffected individuals, and optimize disease management among those affected. This review investigates the progress made in the domains of molecular medicine and genomics as they relate to periodontology.

Periodontal Osseous Defects: A Treatment-Oriented Classification to Guide Regenerative Treatment Planning.

Periodontal bony defects are classified into 'supraosseous' ('suprabony') or 'infraosseous' ('infrabony') according to the location of the base of the defect compared to the coronal part of the residual alveolar crest. Infraosseous defects are generally considered more challenging to treat and are thought to be associated with a higher risk of periodontal progression. The emergence and advancement of periodontal regenerative procedures have improved the clinician's ability to manage infraosseous defects.

Sources: This UK version, based on the supranational EFP guideline [1] published in the Journal of Clinical Periodontology, was developed using S3-level methodology, combining assessment of formal evidence from 13 systematic reviews with a moderated consensus process of a representative group of stakeholders, and accounts for health equality, environmental factors and clinical effectiveness. It encompasses 55 clinical recommendations for the Prevention and Treatment of Peri-implant Diseases, based on the classification for periodontal and peri‑implant diseases and conditions [2].

Periodontal granulation tissue - To remove or not to remove, that is the question.

Formation of granulation tissue is a fundamental phase in periodontal wound healing with subsequent maturation leading to regeneration or repair. However, persistently inflamed granulation tissue presents in osseous defects as a result of periodontitis and is routinely disrupted and discarded with non-surgical and surgical therapy to facilitate wound healing or improve chances of regeneration. Histological assessment suggests that granulation tissue from periodontitis-affected sites is effectively a chronic inflammatory tissue resulting from impaired wound healing due to persistence of bacterial dysbiotic bioflim.

Insights into microorganisms, associated factors, and the oral microbiome in infective endocarditis patients.

Introduction: Infective Endocarditis (IE) is a rare, life-threatening infection of the endocardium with multisystem effects. Culprit microorganisms derived from different niches circulate through the bloodstream and attach to the endocardium, particularly the heart valves. This study aimed to investigate culprit microorganisms among a cross-sectional cohort of IE patients, their associated factors, and to explore the potential relationship to the oral microbiome.

Objective: To elucidate the molecular healing of intrabony defects following non-surgical periodontal therapy (NSPT) using gingival crevicular fluid (GCF).

Background Data: Currently limited information is available regarding the GCF of intrabony defects and the change in biomarker levels in the GCF at early time points following treatment interventions.

Methods: Twenty-one patients (Periodontitis Stage III or IV) who have received NSPT, contributing one intrabony defect and one healthy site were included in this study.

Repurposing Metformin for periodontal disease management as a form of oral-systemic preventive medicine.

Background: Despite the improvements in treatment over the last decades, periodontal disease (PD) affects millions of people around the world and the only treatment available is based on controlling microbial load. Diabetes is known to increase the risk of PD establishment and progression, and recently, glucose metabolism modulation by pharmaceutical or dietarian means has been emphasised as a significant modulator of non-communicable disease development.

Methods: The impact of pharmaceutically controlling glucose metabolism in non-diabetic animals and humans (REBEC, UTN code: U1111-1276-1942) was investigated by repurposing Metformin, as a mean to manage periodontal disease and its associated systemic risk factors.

Objective: The aim of this study was to investigate metabolomics markers in the saliva of patients with periodontal health, gingivitis and periodontitis.

Background: The use of metabolomics for diagnosing and monitoring periodontitis is promising. Although several metabolites have been reported to be altered by inflammation, few studies have examined metabolomics in saliva collected from patients with different periodontal phenotypes.

New-Onset Diabetes Mellitus in COVID-19: A Scoping Review.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic became superimposed on the pre-existing obesity and diabetes mellitus (DM) pandemics. Since COVID-19 infection alters the metabolic equilibrium, it may induce pathophysiologic mechanisms that potentiate new-onset DM, and we evaluated this issue.

Method: A systematic review of the literature published from the 1 January 2020 until the 20 July 2023 was performed (PROSPERO registration number CRD42022341638).

Is subclinical cardiovascular disease linked with periodontal disease in diabetic and non-diabetic subjects?

Periodontal disease leads to a systemic hyper-inflammatory state that might impair other co-morbidities including cardiovascular disease. Evidence-based findings showed that periodontitis may be linked with subclinical signs of cardiovascular diseases such as arterial stiffness. Nevertheless, some contrasting results have been reported over the years.
