    Craniofacial morphology in children with operated complete unilateral cleft lip and palate
    (LIPPINCOTT WILLIAMS & WILKINS, 2008) Goyenc, Yasar Bedii; Gurel, Hakan Gurcan; Memili, Badel
    The objective of the study was to compare the craniofacial characteristics of children with operated unilateral complete cleft lip and palate (UCLP) with those of noncleft children. Lateral and postero-anterior cephalometric radiographs of subjects with UCLP and controls who were matched for sex, age, and ethnic origin were analyzed and compared. There were a total of 21 subjects with UCLP (10 boys and 11 girls) from the Orthodontic Department of Selcuk University and 15 controls (7 boys and 8 girls) from the Orthodontic Department of Ankara University. The nasal bone length in the group with cleft did not differ significantly from that in the control group. Subjects with UCLP included in the study appeared to have shorter faces, smaller mandibulae, greater lateral orbital width, and smaller sella turcicae compared with controls. Unilateral cleft lip and palate affects the intracranial morphology as well as dentofacial structures.

    Rapid canine distalization through segmental alveolar distraction osteogenesis
    (E H ANGLE EDUCATION RESEARCH FOUNDATION, INC, 2007) Sukurica, Yusuf; Karaman, Ali; Gurel, Hakan Gurcan; Dolanmaz, Dogan
    Objective: The objectives of this study were to achieve rapid canine distalization by segmental alveolar distraction method in first premolar extraction cases, to examine the changes in the periodontal tissues surrounding canines, to evaluate the displacement of the canine and first molar teeth, to assess the effects of the procedure on the pulpal vitality of the canines, and to determine the amount of root resorption in retracted canines. Materials and Methods: The sample of the study consisted of 20 teeth in eight patients (four females and four males, mean age 18.5 years). Pre- and posttreatment dental casts, panoramic radiographs, and standard periapical radiographs were taken from all patients. An electrical vitality test was applied before and after the distraction procedure and during the follow-up period (6 months after the completion of the procedure). In addition, six periodontal indices were used to examine the health of the periodontal tissues. Results: The distraction procedure was completed in 12 to 28 days (mean 14.65 +/- 3.49). The anchorage loss ranged from 0 to 3 mm (mean 1.2 +/- 0.83). The distal displacement of the canines ranged from 3 to 8 mm (mean 5.35 +/- 1.22). The canines showed a mean of 9.1 degrees distal tipping, whereas there was no statistically significant change in the axial inclinations of first molars after distraction. Conclusion: We believe that rapid canine distalization by segmental distraction osteogenesis will become a routine protocol and a popular method among orthodontic applications.
