Bacteremia after plate removal and tooth extraction
Summary
Oral surgery, including osteosynthesis plate removal and tooth extraction, frequently causes bacteremia (bacteria in the bloodstream). This study found a high incidence of anaerobic bacteria in blood samples following these procedures.
Area of Science:
- Oral Surgery
- Infectious Diseases
- Bacteriology
Background:
- Mandibular angle fractures often require osteosynthesis plates.
- Surgical removal of implants and teeth can potentially lead to bloodstream infections.
Purpose of the Study:
- To investigate the occurrence and characteristics of bacteremia following the removal of semirigid osteosynthesis plates and adjacent third molars.
- To identify bacterial species involved in post-surgical bacteremia.
Main Methods:
- Bacteriological sampling from oral sites (gingival pocket, extraction socket, plate) and peripheral blood (antecubital vein) in 10 patients.
- Blood samples collected multiple times up to 30 minutes postoperatively.
- Standard culture, isolation, and identification methods for bacterial species.
Main Results:
- Bacteremia was detected in 60% of patients, with peak occurrences shortly after plate removal and tooth extraction.
- 13 different bacterial species were isolated, predominantly anaerobic bacteria (85%), including Actinomyces, Campylobacter, and Lactobacillus.
- Bacterial species found in blood cultures were also present in oral samples.
Conclusions:
- Oral surgical procedures, such as plate removal and tooth extraction, are associated with a high frequency of bacteremia.
- The bacteremia is often prolonged and dominated by anaerobic bacteria.
- These findings highlight a potential risk for patients susceptible to bloodstream infections.

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...

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,...
01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
