Chlorhexidine gluconate, its properties and applications in endodontics

Area of Science:

• Endodontic therapy
• Microbiology
• Dental materials science

Background:

• The primary goal of endodontic therapy is to disinfect the root canal system by eliminating pulpal content, a major source of infection.
• Microorganisms and their by-products are the primary cause of pulpal and periradicular pathosis.
• Mechanical instrumentation, chemical irrigation, and inter-appointment medication are key to achieving disinfection.

Purpose of the Study:

• To review the various aspects of using chlorhexidine in endodontic treatments.
• To highlight chlorhexidine's antimicrobial properties and substantivity.
• To discuss its application in reducing bacterial load within the root canal system.

Main Methods:

• Literature review of studies on chlorhexidine in endodontics.
• Analysis of chlorhexidine's chemical properties, including its cationic structure.
• Evaluation of its antimicrobial spectrum and substantivity.

Main Results:

• Chlorhexidine is a broad-spectrum antimicrobial agent effective against a wide range of microorganisms.
• Its cationic nature confers substantivity, allowing for prolonged antimicrobial activity.
• It serves as a valuable irrigant in endodontic procedures to reduce bacterial contamination.

Conclusions:

• Chlorhexidine is a significant agent in endodontic disinfection due to its antimicrobial efficacy and substantivity.
• Its use contributes to reducing bacterial load and managing pulpal and periradicular pathosis.
• Further research may explore optimal protocols for its application in endodontics.
