The aim is to determine the prevalence of dentition defects and secondary dento-maxillaire deformities in different periods of formation of the dento-maxillary system among the child population of Kyiv and the need for their therapeutic and prophylactic prosthetics, assess the level of prosthodontics care provided to them. Materials and methods. To determine the prevalence of dento-maxillary anomalies, dentition defects, and secondary dento-maxillary deformities, we examined 2276 children and adolescents aged 4 to 17 years in educational institutions in Kyiv for the 2017-2018 period. Results of the research. The prevalence of dento-maxillary anomalies among child population is 65.2%. Angle class I holds first place with 45,8% (among the anomalies of individual teeth), Angle class II comes second with 15,2%, the third place is occupied by Angle class III with 4,2%. Secondary dento-maxillary deformities caused by the early loss of both permanent and especially temporary teeth have become more common among the child population. The main reason for their occurrence is timely uncompensated dentition defects, which was confirmed by mass examinations of children aged 4 to 17 years in schools and kindergartens. Dentition defects of various sizes and localization were observed in 359 out of 2276 children, which is 15.8% of the total number of those examined. Tooth loss is most often caused by caries, its complications, and trauma, a little less often – by retention and anodontia. Secondary dento-maxillary deformities (dento-maxillary lengthening of teeth that have lost their antagonists; the inclination of the teeth towards the defect with displacement) were found in 278 children, which amounted to 12.2% of the total number of examined children, and 77.4% of the detected dentition defects (359 children). The obtained data indicate deterioration in the organization and implementation of oral cavity sanitation among the child population, which requires immediate measures to implement programs aimed at early identification and prevention of severe morphological and functional disorders of the dentition. Conclusions. The results of the obtained findings show a high prevalence of dento-maxillary anomalies among the child population – 65.2% (1484 people), and only 34.8% (792 people) had no orthodontic pathology. Dentition defects were diagnosed in 359 people, which is 15.8% of the total number of the examined children. Secondary dento-maxillary deformities were diagnosed in 278 people of the total number of the examined children (2276 people), that is 12.2% of the total number of the diagnosed dentition defects (359 cases) – 77.4%. Most often, secondary deformities occur between 6 and 11 years of age, that is, in the mixed dentition period of occlusion. The main reason for their occurrence was the inefficient prosthesis of dentition defects or its absence. Dentition defects are caused by premature removal of temporary teeth due to complications of caries, trauma, retention, and congenital absence of teeth.

Objective: To determine prevalence of malocclusion and orthodontic treatment needs in Down syndrome individuals among Sudanese population in Khartoum area.Materials & Method: A total of 75 (37 males and 38 females) Down syndrome individuals age ranging from 6-28 years were clinically examined after obtaining their guardian’s consent, malocclusion was determined based on Angle and Incisor classification. Exclusion criteria were included individuals who had history of extraction and orthodontic treatment.Data was analysed by using SPSS Version 17, at an alpha level 0.05 and 95% confidence limits.Result: Angle Class III and Incisor III malocclusion represents the most prevalent type of malocclusions (58.7%) Angle classification, (53.3%) Incisors classification. Angle Class III malocclusion was more frequent among females (60.5%) than in males (56.8%). Themajority of individuals with Down syndrome are in need of orthodontic treatment (85.3%).Conclusion: The prevalence of malocclusion and orthodontic treatment need among Sudanese Down syndrome individuals was high. Angle and Incisor Class III malocclusion representing commonest trait of malocclusion with more frequency in femalesthan males.Key word: down syndrome, Class III malocclusion, orthodontic treatment

Objective: At Hannover Medical School, treatment of BCLP patients was revised and updated in 1980. The objective of the present study was to evaluate the differences in treatment outcome between BCLP patients treated after the revised concept including infant orthopedics, and BCLP patients who received osteotomy in addition to surgical and orthodontic treatment during childhood. Patients: Nine of 48 BCLP patients born between 1980 and 1983 received surgical and orthodontic treatment according to the Hannover concept. They were compared to 9 of 68 adolescent and adult patients from Hannover without this protocol, who underwent maxillary osteotomy and consecutive orthodontic treatment. Main Outcome Measures: Comparison of the two groups was made at the end of active orthodontic treatment by cast analysis and lateral cephalometrics to evaluate sagittal, transverse, and vertical changes. Results and Conclusions: No patient treated using the revised protocol showed characteristics of skeletal angle class III at any stage of investigation. No indication for osteotomy was found in this group. All patients with osteotomy had skeletal angle class III resulting from insufficient midfacial growth. Sagittal and vertical skeletal relations were successfully improved by osteotomy.

Abstract Objective: To compare the cephalometric characteristics of children with Class III malocclusion to those of children with normal occlusion during the deciduous dentition phase. Materials and Methods: Cephalometric measurements of 27 children (mean age: 5.03 years) diagnosed with Class III malocclusion were compared with 32 children (mean age: 4.85 years) diagnosed with normal occlusion in the following four categories: sagittal skeletal analysis, vertical skeletal analysis, dentoalveolar analysis, and soft tissue analysis. Results: Significant differences were seen in all categories except vertical skeletal analysis. Sagittal skeletal measurements included ANB (Class III group: −0.91 ± 1.60; normal group: 5.28 ± 1.29), facial convexity (Class III group: 0.47 ± 4.32; normal group: 13.65 ± 3.44), Wits appraisal (Class III group: −5.54 ± 2.36; normal group: −0.84 ± 1.91), and A to N-perpendicular (Class III group: −2.94 ± 3.05; normal group: 0.78 ± 2.53). Dentoalveolar measurements included U1 to NA (Class III group: 11.98 ± 5.25; normal group: 8.12 ± 5.43), IMPA (Class III group: 81.34 ± 7.40; normal group: 86.57 ± 5.67), and interincisal angle (Class III group: 152.65 ± 8.82; normal group: 145.03 ± 7.34). Soft tissue measurements included soft tissue convexity (Class III group: 2.47 ± 4.20; normal group: 12.71 ± 3.95), nasofacial angle (Class III group: 22.68 ± 4.22; normal group: 26.24 ± 3.84), and upper lip to esthetic plane (Class III group: −0.65 ± 2.74; normal group: 3.07 ± 1.90). Conclusions: There are significant differences between the craniofacial patterns of normal children and those of children with Class III malocclusion that can be identified with cephalometric analysis as early as the deciduous dentition phase.
