Oral Medicine and Oral Clinical Chemistry Game Changers for Future Plaque Control and Maintenance: PerioSafe® aMMP-8 POCT, Lumoral® 2× PDT- and Lingora® Fermented Lingonberry Oral Rinse-Treatments

<b>Background</b>: Periodontitis is a global health crisis that affects almost half of the world's population and commonly goes unnoticed because of its asymptomatic and pain-free nature. For early and easy detection and treatment, safe and non-invasive chair-side oral fluid biomarker (aMMP-8) diagnostics and new anti-microbial, anti-inflammatory and anti-proteolytic treatment modalities have been developed, which this review aims to introduce. <b>Methods</b>: For convenient diagnosis and tackling of periodontitis, adoption of an oral fluid aMMP-8 chair-side point-of-care rapid diagnostic test (POCT) has been proposed, comparable to home pregnancy and COVID-19 antigen tests, to be conveniently used by healthcare professionals and by patients themselves. To improve treatment of detected periodontitis, Finnish scientists have also developed a potentially industry-altering, biofilm-modulating, anti-microbial, anti-inflammatory, and anti-proteolytic (i) dual-light-activated photodynamic-therapy (2×PDT) and (ii) fermented lingonberry juice (FLJ) oral rinse designed for home personalized medicine and professional use. These new oral medicine technologies are reviewed and some unpublished results are presented. <b>Results</b>: aMMP-8 is the superior biomarker for grade of periodontitis (progression rate) when compared to the total latent/proform MMP-8 (total-MMP-8) and microbial lipopolysaccharide (LPS/LAL) activity. Cut-off 20 ng/mL is the optimal cut-off for aMMP-8 POCT and does not make false positives. Antibacterial 2× PDT light and anti-microbial FLJ treatments can eliminate and reduce problem-causing bacteria and Candida-yeasts from the mouth. <b>Conclusions</b>: These new oral medicine technologies have shown promising results and could have the potential to revolutionize diagnosis, prevention, oral care, plaque control and maintenance. These new game-changer oral medicine technologies have launched a new clinical field in dentistry: oral clinical chemistry.
