METHOD FOR ESTIMATION OF TEETH HARD TISSUE STATE AT EXPOSURE TO ELECTROMAGNETIC RADIATION Russian patent published in 2017 - IPC A61B5/00 A61C19/04 

FIELD: medicine.

SUBSTANCE: to estimate the state of teeth hard tissues when exposed to electromagnetic radiation of the computer monitor before and after 180 minutes after work with the computer, a two-stage diagnosis of the level of computer radiation effect on teeth state is carried out. At the first stage, the electrical conductivity of teeth hard tissues is measured using active, passive electrodes and the Dentist device, measuring at various points of the tooth. Further, if a current value of 8.0-27.7 μA is obtained, the second stage of the study takes place. At the second stage of the study, a solution of hydrochloric acid buffer is applied to the preselected portion of teeth hard tissues for 60 seconds, the buffer is rinsed with an air pistol and the test area is dried for 30 seconds. To better visualize the hydrochloric acid buffer solution in the area of the studied tooth, sour fusion is added to it, which gives it a pink colour. To obtain a drop with a constant contact area with the tooth and prevent its spreading, the hydrochloric acid buffer solution is given an increased viscosity by adding glycerin to its composition. After this, the rate of calcium dissolution in 1 μl of the biopsy is simultaneously determined by the method of microtitration, and the rate of phosphorus dissolution - by the photometric method. Increased rates of calcium dissolution by 77.0% and phosphorus dissolution by 91.1% are assessed as a negative effect of the electromagnetic radiation of the computer monitor, which is manifested by the processes of enamel demineralization.

EFFECT: increased accuracy of diagnosis of demineralization processes emergence with a decreased traumatic nature of the assessment process.
