Panoramic radiograph is a universally used diagnostic method in dentistry for identifying various dental anomalies and assessing developmental stages of the dentition. The second premolar is the tooth with the highest number of developmental abnormalities. The purpose of this study was to generate neural models for assessing the position of the bud of the second premolar tooth based on analysis of tooth–bone indicators of other teeth. The study material consisted of 300 digital pantomographic radiographs of children in their developmental period. The study group consisted of 165 boys and 135 girls. The study included radiographs of patients of Polish nationality, aged 6–10 years, without diagnosed systemic diseases and local disorders. The study resulted in a set of original indicators to accurately assess the development of the second premolar tooth using computer image analysis and neural modelling. Five neural networks were generated, whose test quality was between 68–91%. The network dedicated to all quadrants of the dentition showed the highest test quality at 91%. The training, validation and test subsets were divided in a standard 2:1;1 ratio into 150 training cases, 75 test cases and 75 validation cases.

“…To avoid cases with accelerated eruption of the premolars, a panoramic x-ray confirmed that less than two-thirds of the roots were completed, and the successors were covered by bone. (22) Furthermore, according to Cieślińska K et al (33), during the intraosseous stage, the tooth moves at a rate of 1-10 µm per day which approximately will take 1 mm of bone to resorb in 4 to 5 months. Hence, bone covering over the crown of unerupted successors together with the determined stage of root development indicated the need for a space maintainer.…”

INTRODUCTION:A combination of Nance and transpalatal arch space maintainers has previously been studied in treatment of Angle's class II cases. However, this appliance hasn't been the subject of any trials as a space maintainer. AIM: To evaluate the effectiveness of the combined Nance/transpalatal arch (N-TPA) appliance compared to Nance space maintainer in maintaining arch dimensions after bilateral premature loss of maxillary primary molars. MATERIAL AND METHODS: Thirty children with bilateral premature loss of maxillary primary molars were randomly allocated into two groups (n=15). The test group received the N-TPA appliance, and the control group received the Nance appliance. Baseline measurements including arch circumference, intermolar width and arch depth were recorded. Participants were followed up to 9 months for re-evaluation. RESULTS: No statistical significance was found when comparing arch circumference, intermolar width and arch depth. Intra-group comparison of arch depth in the N-TPA group showed a statistical significance at 9 months. Comparison of difference in arch depth measurements from baseline to follow-up time points showed a statistical significance at 6 and 9 months. CONCLUSION: Both appliances provided acceptable space maintenance regarding arch circumference and arch width. Statistical significance was found when comparing arch depth measurements, however, further research is necessary to confirm clinical significance.

“…Перш за все для кваліфікованої ортодонтичної допомоги лікар повинен провести комплексну діагностику із застосуванням додаткових методів обстеження, як доповнення до клінічних даних. Для оцінки умов та стану розвитку зубів і опорних структур серед рентгенологічних методів, окрім ортопантомографії (ОПТГ) в сучасній ортодонтії широко застосовується цефалометрія, конусно-променева комп'ютерна томографія та інші методи для деталізації діагностики зубощелепних аномалій (ЗЩА) [10,11,19]. Саме рентгенологічні методи дослідження мають велике значення при виборі стратегії лікування адентії зубів.…”

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.
