Tooth enamel and bacterial cell surface interaction

“Tooth enamel and bacterial cell surface” refers to the interaction between the hard, mineralized surface of the tooth (enamel) and the outer surfaces of bacterial cells, particularly in the oral cavity. This interaction is central to the initial attachment of bacteria such as Streptococcus and Actinomyces species to the enamel, facilitated via the formation of the acquired enamel pellicle—an adsorbed protein layer derived from saliva[1][2]. Early colonizing bacteria use surface adhesives (fimbriae, fibrils, and binding proteins) to attach to the pellicle, initiating biofilm (dental plaque) development as they secrete extracellular polysaccharides (EPS) to form a stable matrix. Subsequent acid production by these bacteria, especially aciduric species like Streptococcus mutans, leads to demineralization of enamel and formation of carious lesions (dental caries). This “target” is not a specific molecule or receptor but rather the physical interface and process crucial for oral biofilm assembly and pathogenesis of tooth decay and periodontal disease[1][2][3]. The surface interactions are a focus for preventive therapies, including antimicrobial peptides, antiseptics, and novel biofilm-disrupting agents[3].
