Oral biofilm and dental enamel

The target 'Non-specific oral bacteria and dental enamel surfaces' refers to the complex ecological interface between the polymicrobial biofilm (dental plaque) and the mineralized hydroxyapatite structure of the tooth. Oral bacteria, such as Streptococcus mutans and Lactobacilli, colonize the dental pellicle and ferment dietary carbohydrates into organic acids, which lower the local pH and lead to the demineralization of the enamel (StatPearls, 2023). This process is the primary driver of dental caries, one of the most prevalent chronic diseases worldwide. Therapeutic interventions targeting this system aim to either reduce the bacterial load using antimicrobials like chlorhexidine or reinforce the enamel surface using remineralizing agents (NIH, 2022). Fluoride is the most common therapeutic agent, working by substituting hydroxyl groups in hydroxyapatite to form fluorapatite, which has a lower solubility constant and higher resistance to acid dissolution (PubChem). Additionally, agents like xylitol can interfere with bacterial growth and acid production by acting as a non-fermentable sugar alcohol. Effective management of this target involves maintaining a balance in the oral microbiome to prevent the transition from commensal to pathogenic states while preserving the mineral integrity of the tooth surface.

Drugs targeting this system act by inhibiting bacterial enzymes (e.g., enolase), disrupting microbial cell membranes, interfering with bacterial adhesion to the dental pellicle, and promoting the remineralization of enamel by forming acid-resistant fluorapatite.
