Efficacy of using oxygen microbubble device for facultative anaerobe removal

Area of Science:

• Biomedical Engineering
• Oral Microbiology
• Periodontology

Background:

• Serious gingivitis and periodontal diseases cause receding gums, complicating oral hygiene.
• Mechanical brushing can exacerbate bleeding and wounds, hindering the removal of anaerobic bacteria from gum pockets.

Purpose of the Study:

• To develop and evaluate a novel cleaning device utilizing oxygen microbubbles.
• To investigate the efficacy of this device in eliminating facultative anaerobes in the oral cavity.

Main Methods:

• Simulations were performed using a denture model to assess device performance.
• Key design variables manipulated included bubble generator rotation speed, nozzle diameter, and number of nozzle holes.

Main Results:

• The oxygen microbubble device demonstrated significant effectiveness in removing facultative anaerobes.
• The number of nozzle holes was identified as the most critical design factor influencing efficacy.
• Increased nozzle count led to greater flow volume, oxygen content, and superior anaerobe removal.

Conclusions:

• Oxygen microbubble technology presents a promising approach for managing anaerobic bacteria in periodontal pockets.
• Device design, particularly the number of nozzles, is crucial for maximizing therapeutic outcomes in oral hygiene.
