Summary
Periodontal procedures like scaling can cause bacteremia (bacteria in the bloodstream) in most patients with periodontitis. This highlights the importance of antibiotic prophylaxis to prevent potential systemic complications.
Area of Science:
- Oral Medicine and Periodontology
- Infectious Diseases
- Microbiology
Context:
- Bacteremia is a common occurrence following dental and oral surgical procedures.
- Periodontal disease may influence the prevalence and types of bacteria causing bacteremia.
- Periodontal disease is increasingly recognized as a potential risk factor for systemic health issues.
Purpose:
- To investigate the frequency of aerobic and anaerobic bacteria in the bloodstream after scaling and root planing.
- To assess the impact of periodontal treatment on the incidence of bacteremia in patients with chronic periodontitis.
Summary:
- A study involving 13 patients with generalized chronic periodontitis found no bacteremia pre-treatment.
- Following full-mouth scaling, bacteremia occurred in 76.9% of patients.
- Anaerobic bacteria, including Prevotella spp., Micromonas micros, and Fusobacterium nucleatum, were the predominant microorganisms detected.
Impact:
- Periodontal procedures can induce bacteremia, posing a risk for systemic complications.
- Findings underscore the critical role of antibiotic prophylaxis in preventing bacteremia and associated systemic risks after periodontal treatment.

01:27The Oral Microbiota
The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...
01:28Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

This lesson will focus on the different treatment options for managing tonsillitis, which typically depend on the cause and severity.
01:28Acute Pyelonephritis II: Diagnostic Studies and Management
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
01:24Bacterial Meningitis
Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
01:30Bacterial Signaling
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...
