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.
