Popis: The prevalence of dento-alveolar anomalies in the structure of dental morbidity ranks the third position following dental caries and periodontal diseases. Signs of normal teething are the following: timeliness, sequence in relation to certain groups of teeth, evenness, eruption of teeth first in the lower jaw and then in the upper jaw. The timing of the eruption for deciduous and permanent teeth can shift in one direction or another. There is a distinction between premature and delayed teething. According to the literature, there are two options for the eruption of canines and premolars: premolars appear first (at the age of 7-11 years) followed by canines, or canines can erupt first (at the age 8 to 12 years) then followed by premolars. Both patterns are independent of gender and race. The purpose of this study is to determine the timing and sequence of eruption for permanent canines and premolars in children of Poltava Region and to establish the influence of eruption timing on the development of dental alveolar anomalies. The results of our research have demonstrated that the most common pathology is the anomaly of the position of individual teeth, or Class I according to Angle, which is diagnosed in 77.6% (615 cases) of patients over the period of tooth change. Class II malocclusion according to Angle, or distal bite is found in 150 patients (18.9%), in 68 patients in the first period of the mixed dentition and in 82 in the second period. Mesial bite, or class III according to Angle is diagnosed in 3.4% (27) of study subjects. Pathology in the vertical plane, namely, a deep bite is diagnosed in 153 people, 19.31% of them have open bite, and 6.56% (52 cases) have close bite, 2.77% (22) of patients have cross bite. Thus, the commonest orthodontic pathology in the mixed dentition of patients with of dento-alveolar anomalies from the Poltava region is the abnormality of the position of individual teeth, or Class I pathology according to Angle. The number of patients having this diagnosis is 77.6% of all children who searched for orthodontic care at this age. We have not found any special relationship between the nature of teeth eruption, gender and type of dental alveolar anomaly in orthodontic patients of Poltava region during the period of tooth change.
