MODERN INDICATORS OF UPPER JAW PROTRUSION IN CHILDREN UNDER THE INFLUENCE OF VARIOUS EXTERNAL FACTORS

Abstract

Many studies have been conducted to determine the prevalence of dental anomalies. It should be borne in mind that the occurrence of anomalies depends on the structure and size of the studied population group, criteria and methods used by doctors in assessing a particular anomaly (Mitchell L., 2015). Currently, according to numerous studies, the number of maxillary-facial anomalies is increasing. Studies of skeletal remains prove that today the prevalence of anomalies is many times higher than their level than 1000 years ago. And until relatively recently, crowding and displacement of teeth were atypical (Proffit U.R., 2006).
