ANALYSIS OF BONE DENSITY OF THE RABBIT LOWER JAW ACCORDING TO RADIOVIZIOGRAPHIYA

Abstract

Nowadays, the premature loss of teeth is a serious problem not only dental but also a general medical.The results of dental prosthetics are largely determined by the condition of the bone tissue o f the jaw. Modern radiological examination methods make it possible to determine the quality of bone tissue, the biomarker of which is the mineral density indicator. Experimental methods play an important role in understanding the processes occurring in the body during the development of pathological conditions. The aim of our research was to fi nd out the peculiarities of mineral density of bone tissue in diff erent parts of the lower jaw of the intact rabbit. 10 lower jaws of sexually mature intact rabbits aged 6-7 months, weighing 2.5-3 kg were used for the study. It was established that the bone tissue density indicators of diff erent parts of the body of the lower jaw of an intact rabbit are characterized by features peculiar to each of the studied parts and caused, obviously, by diff erent loads on the bone tissue during articulatory movements. The alveolar part of the body of the lower jaw at the level of the molars has the highest density of bone tissue, the lowest one is the main part of the body o the lower jaw at the level of the incisors. The density of the bone tissue of the alveolar part of the body of the lower jaw gradually increases in the direction from the incisors to the molars, the density of the main part of the body of the lower jaw is the lowest at the incisors level of the, the highest – between the incisors and the molars. At the level of the incisors and molars, the density of the bone tissue of the alveolar part of the lower jaw body is higher, and between the incisors and the molars, it is lower than the density of the bone tissue of its main part.
