METHOD OF ANALYSIS OF CALCULUS FORMATION SENSITIVITY TO GLUCOSE Russian patent published in 2011 - IPC G09B23/28 

FIELD: medicine.

SUBSTANCE: analysing calculus formation sensitivity to glucose is ensured by examining an oral fluid of people with healthy oral cavity and periodontium. A model medium of the following composition is created: CaCl₂·2H₂O - 0.6931 g/l, (NH₄)₂HPO₄ - 0.2376 g/l, K₂HPO₄·3H₂O - 5.0000 g/l, NaF - 0.4452 g/l, MgCl₂·6H₂O - 0.1319 g/l, NaHCO₃ - 0.7844 g/l, KCl - 0.1076 g/l which is added with glucose in amount 0.0108, 0.108 and 1.08 g/l. A healthy tooth is placed in the model medium and observed for a long period of time. Calculus hydroxylapatite crystallisation rate is estimated by the relation of a Ca/P-coefficient.

EFFECT: method enables detection of propensity for calculus formation.
