The application of ultrasonic densitometry for assessing the state of periodontal bone tissue in persons with physiological occlusion (experimental clinical study)

Aim . To improve the methods for assessing state of jaw bone tissue based on use ultrasonic shadow densitometry. Materials and As a research method, there was used latest development – velocimetric densitometer with an original software, sensors electronic positioner. The material experimental study were macropreparations animal species "Domestic Pig", where spongy cortical substance isolated, speed passage ultrasound (SUS) through them estimated. In clinical part study, diagnostics performed in 38 people physiological occlusion various anatomical functional areas. Results Part showed that maximum SUS observed from oral side, minimum substance. registration measurements revealed statistically significant differences highest density determined anterior left right parts mandible. lowest lateral sections upper jaw. Conclusions Based conducted studies, developed diagnostic map periodontal tissue, which can complement protocol patient's dental examination. obtained results zones lower jaws examined persons be taken as normalized indicators density. Ultrasound densitometry has proven to safe, non-invasive method vivo.
