Non-specific physicochemical interactions with dental tissues and fluids

This category encompasses the broad range of non-specific physical and chemical interactions between exogenous substances and the oral environment, including mineralized tissues like enamel and dentin as well as saliva (PubMed: 25628372). Unlike traditional pharmacological targets such as receptors or enzymes, these interactions are driven by surface energy, electrostatic forces, and chemical affinity for the hydroxyapatite crystal lattice (NIH). For instance, fluoride ions promote remineralization by substituting hydroxyl groups in hydroxyapatite to form more acid-resistant fluorapatite (StatPearls). Similarly, the substantivity of antimicrobials like chlorhexidine is due to their non-specific binding to the acquired salivary pellicle and oral mucosa, allowing for prolonged therapeutic effects (PubMed: 12617604). These processes are essential for the prevention of dental caries and the management of periodontal diseases through topical delivery systems. Understanding these physicochemical dynamics is vital for optimizing the retention and efficacy of dental materials and therapeutic agents.
