INFORMATION TECHNOLOGIES IN INDENTIFYING THE STRUCTURES OF DENTAL HARD TISSUES UNDER SYSTEMIC CONCEPTION: the specified physics-mathematical model aimed at its identification

For specifying the physics-mathematical model (PMM) of the dental hard tissues (DHT) aimed at its further identification, the results of measurements of tooth slice parameters are presented and analyzed on the base of the coordinate-information-measurement complex (CIMC). By its functional purpose the CIMC is analogous to a digitizer, but differs in that the CIMC at each point transforms into digital code the resistance value of the investigated object. Thus the measured parameters are the values of active resistances at discrete slice points resulting from line-by-line or other scanning of the tooth slice surface. The results of comparing the application of electrical acoustic signal and the X-ray tomography are presented, as well as recommendations allowing to decrease the measurement error caused by influencing factors in performing the experiment with an electrical acoustic signal. On the basis of experiment results the form and parameters of the DHT approximating cone structure in the synthesis of DHT PMM are specified. Through generating the graphical image of the investigated bio-object on the base of the electrical acoustic signal the fractal regularity of the DHT structure has been revealed.
