Glutaraldehyde in dentistry--a review

Area of Science:

• Biochemistry
• Microbiology
• Dental Surgery

Background:

• Glutaraldehyde is a widely researched chemical compound.
• Its disinfective and fixative properties are of significant interest.
• Recent studies highlight its efficacy against various microorganisms, including the Human Immunodeficiency Virus (HIV).

Purpose of the Study:

• To investigate the disinfective and fixative properties of glutaraldehyde.
• To evaluate its effectiveness against microorganisms, spores, and the HIV virus.
• To assess its suitability for sterilization and therapeutic applications in dentistry.

Main Methods:

• Review of existing studies on glutaraldehyde's properties.
• Analysis of its application in sterilizing surgical instruments, operating areas, and dental materials.
• Examination of its use in endodontic therapy and pulpotomy procedures.

Main Results:

• Glutaraldehyde exhibits broad-spectrum antimicrobial activity, including against spores and HIV.
• A 2% concentration is recommended for sterilizing surgical instruments, operating areas, dental impressions, and root canals.
• It functions as an effective fixative with limited penetration, quick action, and minimal side effects.
• Pulpotomy studies show high success rates when using glutaraldehyde, with vital pulpal tissue remaining at the apical third.

Conclusions:

• Glutaraldehyde is a highly effective disinfectant and fixative agent.
• Its application is beneficial in healthcare settings for sterilization and in endodontic procedures.
• Systemic distribution is minimal and rapidly metabolized, indicating a favorable safety profile.
