Summary
Dental implant placement rarely causes significant bacteraemia. A chlorhexidine digluconate (CHX) mouthrinse showed potential in preventing bacteraemia, suggesting it may be a viable alternative to antibiotics for at-risk patients.
Area of Science:
- Oral surgery
- Infectious diseases
- Microbiology
Background:
- Bacteraemia following dental implant placement is a potential concern, especially for patients at risk of infective endocarditis.
- The efficacy of prophylactic measures, such as antibiotic use, is debated.
Purpose of the Study:
- To determine the prevalence and duration of bacteraemia after implant surgery.
- To evaluate the prophylactic effectiveness of a chlorhexidine digluconate (CHX) mouthrinse.
Main Methods:
- Fifty patients undergoing implant placement were randomized into two groups: a control group (no prophylaxis) and a CHX group (0.2% CHX mouthrinse).
- Blood samples were collected at baseline, 30 seconds, and 15 minutes post-surgery.
- Bacterial cultures were analyzed using automated systems and conventional microbiological techniques.
Main Results:
- Bacteraemia prevalence was 2% at baseline.
- In the control group, bacteraemia occurred in 6.7% of samples at 30 seconds and 3.3% at 15 minutes, with no significant difference from baseline.
- No bacteraemia was detected in the CHX group at any time point.
Conclusions:
- Implant placement using a mucoperiosteal flap does not pose a significant bacteraemia risk.
- The routine use of antibiotic prophylaxis for preventing focal infections in at-risk patients undergoing implant placement is questionable.
- A 0.2% CHX mouthrinse is recommended as a prophylactic measure before dental implant procedures.

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...
01:28Development 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,...
01:25Endocarditis I: Introduction
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
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...
01:27The 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...
