Acquired enamel pellicle and dental plaque extracellular polymeric substance matrix (AEP/EPS matrix)

The tooth-surface pellicle and plaque biofilm matrix represent a complex, multi-component environment essential for oral microbial colonization and enamel protection. The acquired enamel pellicle (AEP) is an acellular film composed of salivary glycoproteins, phosphoproteins, and lipids that forms rapidly on the tooth surface, serving as a protective barrier against acid erosion while providing specific receptors for primary bacterial colonizers [1][2]. As bacteria proliferate, they secrete extracellular polymeric substances (EPS), primarily glucans and fructans, which form the plaque biofilm matrix. This matrix provides structural integrity, facilitates cell-cell communication, and acts as a protective shield against host immune responses and antimicrobial agents [3][4]. Targeting this matrix involves disrupting the biochemical bonds within the EPS or preventing the initial formation of the pellicle to mitigate the development of dental caries and periodontal diseases [5].
