Bacteremia Following Closed and Open Dental Extraction

Area of Science:

• Oral Surgery
• Infectious Diseases
• Microbiology

Background:

• Bacteremia, the presence of bacteria in the bloodstream, can occur after dental procedures.
• Understanding bacteremia following dental extractions is crucial for patient management and infection control.

Purpose of the Study:

• To investigate and compare the incidence of bacteremia after closed versus open dental extractions.
• To identify factors influencing bacteremia post-extraction.

Main Methods:

• Two groups of 29 patients underwent either closed or open dental extraction.
• Blood samples were collected preoperatively, 30 seconds, and 15 minutes post-surgery.
• Anaerobic and aerobic hemocultures were used to detect bacteremia.

Main Results:

• Bacteremia was detected preoperatively in 6.9% (closed) and 1.7% (open) extractions.
• Thirty seconds post-surgery, bacteremia was observed in 10.3% (closed) and 5.2% (open) patients.
• No significant difference in bacteremia rates between closed and open extractions was found at 30 seconds or 15 minutes.
• Coagulase-negative Staphylococcus was the most common microorganism identified.

Conclusions:

• The type of dental extraction (closed or open) does not significantly affect the presence of bacteremia.
• Bacteremia rates were higher at 30 seconds post-surgery compared to preoperative samples.
• Age was found to be significantly related to the presence of bacteremia.
