Salivary proteins, mucins, and acquired enamel pellicle components (AEP) (AEP)

The salivary proteins, mucins, and acquired enamel pellicle (AEP) components represent a diverse group of molecules that form the primary interface between the oral environment and tooth surfaces. The AEP is a thin, acellular film formed by the selective adsorption of salivary glycoproteins and phosphoproteins, such as statherin, cystatins, and proline-rich proteins, onto the hydroxyapatite surface of teeth (Siqueira et al., 2012, Journal of Dental Research) [1]. This structure acts as a semi-permeable barrier that regulates mineral homeostasis, promotes remineralization, and protects against acid-induced erosion (Hannig & Hannig, 2009, Monographs in Oral Science) [2]. Salivary mucins, specifically MUC5B and MUC7, play a vital role in lubricating oral tissues and aggregating bacteria to facilitate their clearance from the mouth (Frenkel & Ribbeck, 2015, Journal of Oral Microbiology) [3]. Dysregulation or deficiency in these components is linked to dental caries, periodontal disease, and xerostomia (Lendenmann et al., 2000, Advances in Dental Research) [4]. Pharmacological agents, including fluoride and antimicrobial rinses, interact with this protein layer to modify bacterial adhesion and enhance the protective properties of the tooth surface (Zero, 2006, BMC Oral Health) [5].
