Background: Antimicrobial peptides (AMPs) are small, naturally occurring molecules that are integral components of the innateimmune system across many organisms. In humans, saliva is rich in various AMPs that play a pivotal role in maintaining oral health by serving as the primary line of defense in the oral cavity. These peptides are essential for protection against a broad spectrum of pathogens, including bacteria and fungi. Recently, active research has been conducted on both naturally occurring AMPs and modified or synthetic AMPs for the treatment of oral pathogens and their application in dental materials. Methods: We compiled previous studies on AMPs present in saliva and their target oral microorganisms. Additionally, wesummarized research on artificially created AMPs targeting oral pathogens. Furthermore, we analyzed recent trends in applied studies, such as the development of oral rinses, toothpaste, and implant coatings using AMPs. Results: Through a literature review, we identified 19 studies on AMPs present in the oral cavity and 40 studies testing AMPs derivedfrom other organisms or synthetically engineered against oral pathogens. Additionally, we reviewed seven studies on the development of implant coatings and oral hygiene material additives using AMPs. These findings suggest the potential for discovering or developing AMPs with activity against specific oral pathogens that can be applied to improve oral health. Conclusion AMPs exhibit broad antimicrobial activity against a wide range of pathogens. Their mechanisms of action primarilyinvolve attacking and disrupting the cell membranes of target microorganisms, making them effective against various pathogens.AMPs have the potential for use as coating materials for dental implants or restorative materials that require long-term use.Further research is needed to investigate the cytotoxicity, durability, and stability of AMPs in the oral environment to support their clinical use in dentistry.

Background: Recent studies have elucidated the quorum-sensing mechanisms, biofilm formation, inter-pathogen interactions,and genes related to oral pathogens. This review aims to explore the recent expansion of drug targets against oral pathogens and summarize the current research on novel antibiotic substances derived from marine organisms that target oral pathogens. Methods: A comprehensive literature review summarized the novel mechanisms pertaining to quorum-sensing signal transmission systems, biofilm formation, and metabolite exchange in oral pathogens. The amino acid sequences of the 16 proteins identified as potential drug targets were systematically classified and compared across various oral microorganisms. Results: Through a literature review, we identified nine studies researching quorum sensing signaling inhibitors targeting oral pathogens. A comparison of the amino acid sequences of 16 potential drug targets in oral microorganisms revealed significant differences between oral pathogens and beneficial oral symbiotic microorganisms. These findings imply that it is possible to design drugs that can bind more selectively to oral pathogens. Conclusion By summarizing the results of recent research on the signaling mechanisms that cause pathogenicity, new drug targets against oral pathogens were proposed. Additionally, the current status of developing new antibiotics for oral pathogens using recently developed quorum sensing inhibitors and natural products derived from marine organisms was introduced.Consequently, marine natural products can be used to develop drugs targeting new proteins in oral pathogens.
