Metronidazole: its use in clinical dentistry

Area of Science:

• Microbiology
• Pharmacology
• Dentistry

Background:

• Obligate anaerobic bacteria play a significant role in oral disease etiology.
• Targeted chemotherapeutic control of specific anaerobic pathogens is desirable.
• Nitroimidazoles, including metronidazole, are a class of anti-anaerobic drugs.

Purpose of the Study:

• To review the literature on the efficacy and safety of metronidazole in dentistry.
• To evaluate metronidazole's pharmacokinetic properties and mechanism of action.
• To identify clinical applications and contraindications for metronidazole in oral infections.

Main Methods:

• Literature review of studies on metronidazole.
• Analysis of pharmacokinetic data (absorption, blood/saliva levels).
• Review of clinical evidence for efficacy in various oral conditions.

Main Results:

• Metronidazole is rapidly absorbed and reaches bactericidal levels within 1 hour.
• The drug specifically targets anaerobic bacteria, sparing aerobic flora, with rare resistance development.
• Metronidazole is proven effective for acute ulcerative gingivitis, pericoronitis, periapical infections, osteomyelitis, and infected sockets.

Conclusions:

• Metronidazole is a safe and effective antimicrobial agent for specific anaerobic oral infections.
• Its targeted action and favorable safety profile make it valuable in dental practice.
• Potential use in chronic periodontitis where anaerobes are implicated warrants further investigation.
