Oral bacterial cells

Oral bacterial cells represent a vast community of microorganisms, including over 700 species, that inhabit the human mouth and form complex biofilms on teeth and mucosal surfaces (Dewhirst et al., 2010). These bacteria are essential for maintaining oral health by preventing the colonization of exogenous pathogens and participating in metabolic processes like nitrate reduction (Marsh, 2003). However, shifts in the microbial composition, often driven by dietary habits or poor hygiene, lead to dysbiosis and the development of oral diseases such as dental caries and periodontitis (Hajishengallis, 2015). Pathogenic bacteria like Streptococcus mutans produce organic acids that demineralize tooth enamel, while others like Porphyromonas gingivalis trigger chronic inflammatory responses that destroy supporting bone (StatPearls, 2023). Beyond the oral cavity, these bacteria are implicated in systemic conditions, including infective endocarditis and cardiovascular disease, through bacteremia and systemic inflammation (NIH, 2022). Therapeutic interventions target these cells using antiseptics like chlorhexidine, which disrupts cell membranes, or antibiotics that inhibit essential cellular functions, though modern approaches increasingly focus on restoring microbial balance rather than total eradication (PubChem, 2023).
