Bacterial pathogens associated with oral disease

Bacterial pathogens associated with oral disease refers to a diverse group of microorganisms, primarily bacteria, that inhabit the oral cavity and contribute to dental and periodontal pathologies (Marsh, 2004 [https://pubmed.ncbi.nlm.nih.gov/15357667/]). Key species include Streptococcus mutans, which is a primary driver of dental caries through the fermentation of dietary sugars into organic acids, leading to enamel demineralization (NIH, 2023 [https://www.nidcr.nih.gov/health-info/oral-hygiene]). Periodontal diseases are associated with a shift toward anaerobic Gram-negative bacteria, specifically the "Red Complex" pathogens: Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola (Socransky et al., 1998 [https://pubmed.ncbi.nlm.nih.gov/9608110/]). These organisms typically exist within complex biofilms known as dental plaque, which shield them from host immune responses and increase their tolerance to antimicrobial agents. Therapeutic management involves the use of antiseptics like chlorhexidine or antibiotics such as metronidazole to reduce the pathogen load and disrupt biofilm structure (StatPearls, 2023 [https://www.ncbi.nlm.nih.gov/books/NBK554590/]). Furthermore, chronic oral infections are increasingly recognized as risk factors for systemic conditions, including cardiovascular disease and diabetes, emphasizing the importance of targeting these pathogens for overall health (Mayo Clinic, 2022 [https://www.mayoclinic.org/healthy-lifestyle/adult-health/in-depth/oral-health/art-20047475]).
