in medicine to assess the caries-protective properties of oral fluid are indicative of the following parameters:
salivation rate / viscosity of oral fluid / acidity (pH) of oral fluid / buffer properties of oral fluid / remineralization rate of enamel & mineralizing potential of saliva.
the crystal-forming individual properties of saliva are quite variable. The mineralizing properties of saliva are evaluated by its ability to restore enamel damaged by acid
From the project theory:
Caries-protective capabilities of oral fluid:
forms a pellicle on the surface of teeth due to glycoprotein mucin; forms a biofilm (interacting community of microorganisms); shows antimicrobial activity due to the presence of immunoglobulins that reduce adhesion of microorganisms to enamel; fermentation (lysozyme, lactoferrin, lactoperoxidase - which have bacteriostatic and bactericidal effects; dissolves (clearance) food residues due to the amount and viscosity of saliva, salivation rate; neutralizes acids due to the buffer system; participates in (re) mineralization of hard dental tissues due to the calcium, phosphate and fluoride contained in saliva, etc.
without the restoration of these properties, and the mechanisms of the salivary glands, the protection will not be complete. Of course, all this is included in the project.
There are tests available, they are sold in our pharmacies. I think you can find them in your area if you ask around
