Aim: Maxillary dental arch widths were evaluated in individuals having unilateral (UCLP) and bilateral (BCLP) cleft lip and palate (CLP) using three-dimensional (3D) digital models. Material and Method: The study had been conducted on 80 individuals aged between 14 - 17 years having UCLP and BCLP. 40 of the individuals had UCLP, whereas 40 had BCLP. The maxillary dental models taken from patients before the treatment were scanned using Orthomodel Programme (v.1.01, Orthomodel Inc., Istanbul, Turkey) to obtain 3D imagery. Student’s t-test was used in order to assess the data obtained by using SPSS software version 22.0. Results: In BCLP, the average inter-canine distance was 17.44 ± 1.31 mm, the average inter-molar distance was 36.57 ± 1.12 mm, while inter-canine/inter-molar ratio was 0.47. Whereas in UCLP, it was 25.10 ± 0.63 mm, 42.20 ± 0.53 mm and 0.59. The inter-canine distance in UCLP was found to be large enough to be statistically significant (p 0.05), even though there were differences in inter-molar widths. Conclusion: For the stable orthodontic treatment results, one of the most important points is arch form and widths to be coherent with each other. In our study, the increase of inter-canine distance seen in UCLP indicates that in the cleft region, the maxillary arch is inclined over to the back, while the same situation in BCLP suggests that the maxillary segments are collapsed inside. The difference in the arch is highly affected by the primary surgical treatment. 展开更多

Objectives: The aim of this study is to determine the distribution of morphological differences in the cli- nical mandibular arch forms seen in Angle Class I, II and III malocclusions in Turkish population and to examine the effect of gender on arch dimension pa- rameters. Material and methods: This study has been conducted on pretreatment mandibular study models of 600 individuals (362 girls, 238 boys) aged between 14 and 19. On the photocopies derived from these models, 4 linear and 2 proportional measurements have been made. The samples have been evaluated as square, ovoid and tapered (OrthoForm-3M Unitek) arch form templates. Results: The most frequent arch form encountered among all the groups was the ta- pered one (62.5%) followed by the ovoid (27.3%) and the square one (10.2%). Gender difference influences on morphological structure was apparent. Generally, compared with girls, arch width and depth were found to be more in boys. Conclusion: The most fre- quent arch form seen in Angle malocclusion groups was the tapered one, followed by the less frequent ovoid and square ones. 展开更多

Design: Comparative-measures study. Material: 3D images of the study models of children with complete unilateral cleft lip and palate (n: 119) at an average age of 9 years were included to the study. All subjects had their cleft lip and palate repaired in many hospitals by different surgeons, but no alveolar graft or any orthodontic treatment was performed. Method: Digital views of the models were used by Orthomodel software program. 3D images of the study models were scored by two groups of raters (Group I: 10 experienced orthodontists, Group II: 10 post-graduate orthodontic stu-dents) after careful perusal of published literature concerning GOSLON scoring and examining dental models samples. Main outcome measures: Statistics of intra- and inter-rater agreement. Results: Intra-rater agreement measurements of the two groups were high and high inter-rater agreement was also found between the two groups. Conclusion: Based on the results of this study clinical orthodontic experience does not affect significantly the reliability of the GOSLON Yardstick when all the raters trained before scoring. 展开更多

Purpose: The evaluation of the patients with clefts;the number, type, distribution by gender, etiological factors in Aegean region in Turkey between the years 2000 to 2011. Material and Method: The patients with clefts who referred to Ege University from different cities were evaluated. The number of the clefts, the type of the clefts, and the causative etiological factors which were known, were recorded for each year separately, from 2000 to 2011. At the same time, the distribution of the gender was made for each year. Chi-square test is used for the statistical evaluation. Results: According to the results of the study, the numbers of the patients with clefts were increased day by day. Totally 741 (49.6% female, 50.4% male) patients with clefts were identified. Unilateral complete cleft lip and palate appeared in the left side was seen more in males (23.8%), while seconder palate cleft was seen more in females (16.7%). Drugs, which were used in the first trimester of the pregnancy, were the most seen etiological factors for the clefts (42.5%), while genetic was 23.3% only. Conclusion: The prevention for one of the mostly seen congenital anomaly;cleft lip and palate is still unknown. For this reason, the determination of the newborn babies with cleft lip and palate has an important role in order to give these patients more effective treatment. 展开更多
