Alternative Antibiotics in Dentistry: Antimicrobial Peptides

Area of Science:

• Microbiology
• Infectious Diseases
• Biochemistry

Background:

• Antibiotic resistance is a significant global health concern, driven by the overuse and misuse of conventional antibiotics in medicine and dentistry.
• Traditional antimicrobial agents used in dentistry, such as chlorohexidine and calcium hydroxide, face challenges with efficacy and resistance.
• Antimicrobial peptides (AMPs), also known as host defense peptides, are a crucial component of innate immunity across diverse life forms.

Purpose of the Study:

• To review the current landscape of antibiotic resistance in oral infections.
• To explore antimicrobial peptides (AMPs) as a viable alternative to conventional antibiotics.
• To summarize the characteristics, mechanisms of action, and potential applications of AMPs in combating oral bacterial infections.

Main Methods:

• Literature review focusing on oral microbiome, oral infections, traditional antibiotics, and antimicrobial peptides.
• Analysis of the properties and mechanisms of action of cationic AMPs.
• Overview of natural and synthetic AMPs derived from animal sources.

Main Results:

• Antimicrobial peptides (AMPs) demonstrate significant potential as biocompatible agents against oral bacteria.
• AMPs exhibit diverse mechanisms for combating pathogens, playing a key role in innate immunity.
• Despite their promise, only a limited number of AMPs have received clinical approval.

Conclusions:

• Antimicrobial peptides (AMPs) represent a promising therapeutic strategy to address the challenge of antibiotic-resistant bacteria in oral infections.
• Further research and clinical development are needed to expand the use of AMPs in dental and medical applications.
• Understanding AMPs' characteristics and mechanisms is crucial for developing effective treatments against resistant pathogens.
