Bu çalışmanın amacı, ortodontik anomalilere sebep olabilen oral alışkanlıkların görülme sıklıklarını incelemek ve doğum şekli ve doğum sonrası faktörlerle (anne sütü alımı ve kardeş sayısı) ilişkisini saptamaktır. GEREÇ VE YÖNTEM: Kırıkkale Üniversitesi Diş Hekimliği Fakültesi Ortodonti Anabilim Dalı'na 2012-2015 yılları arasında başvuran, 48'i erkek, 92'si kız olmak üzere toplamda 140 çocuğun (yaş ortalaması: 13.56±2.34 yıl) anamnez ve muayene formlarındaki bilgiler değerlendirildi. Çocukların doğum şekli (normal/sezaryen doğum), anne sütü alıp/almama durumu, kardeş sayıları ve oral alışkanlıklarının (parmak veya dudak emme, tırnak yeme, diş sıkma, anormal yutkunma ve ağız solunumu) bulunup bulunmadığı tespit edildi. Ardından doğum şekli, anne sütü alımı ve kardeş sayısının oral alışkanlık ile ilişkisi değerlendirildi. İstatistiksel değerlendirme için kikare testi kullanıldı ve p<0.05 değeri anlamlı olarak kabul edildi. BULGULAR: Bireylerin %35.7'sinde (n=50; 29 kız, 21 erkek) oral alışkanlık mevcuttu. Anne sütü almamış bireylerde oral alışkanlık görülme oranı anne sütü almış bireylere göre daha yüksek bulundu (p<0.001). Doğum şekli ve kardeş sayısının oral alışkanlıklar ile ilişkisi bulunmadı (p>0.05). SONUÇ: Anne sütü alımı oral alışkanlıkların görülme riskini azaltabilmektedir.

Objectives: The aim of this study is to evaluate the dentofacial transversal norms according to the stages of skeletal maturation in growing Turkish individuals and to determine differences between the genders. Materials and Methods: In our multi-centered, cross-sectional retrospective study, in which transversal measurements were made according to skeletal maturation stages (SMSs), posteroanterior radiographs of 572 individuals (292 female, 280 male) with skeletal and dental Class I relationships and good occlusion were examined at the age range of 7–18 years. SMSs were determined using Björk, Grave and Brown hand-wrist radiography. A linear regression model was used for changes of transversal measurements between SMSs, and t-test was used to determine transverse changes between the genders. Results: There was no statistically significant difference between females and males in cranial, facial, and nasal width values up to SMS 5. In maxillary, mandibular, maxillary intermolar, and mandibular intermolar width measurements, males had higher values in most stages of skeletal maturation compared to females. Apart from nasal width and maxillomandibular ratio values in females, the regression model in which transversal measurements were dependent variables, and SMS were independent variables was found to be significant. According to cumulative growth percentages, the growth completion in transversal measurements occurred earlier in females. Conclusion: Transversal measurements determined according to the stages of skeletal maturation can be a guide for orthodontists in the clinic to determine values that deviate from normal.

Aim: This study aimed to determine the dentofacial transverse dimensions according to the hand-wrist and cervical vertebrae skeletal maturation stages in order to evaluate the differences between the sexes, to identify the correlations between transverse measurements, and to compare the transverse measurements of individuals of different origins with those of Turkish individuals. Methodology: Transverse measurements were performed using the posteroanterior radiographs of 265 Turkish individuals (150 females, 115 males) at 7–17 years of age. Skeletal maturation was evaluated using hand-wrist radiographs and lateral cephalometric radiographs, and the results were used to categorize the patients into 3 stages of hand-wrist skeletal maturity (prepubertal/pubertal/postpubertal) and 2 stages of cervical vertebrae maturity (prespurt/postspurt). Seven measurements were evaluated. A multivariate linear regression model was used to evaluate the correlations between transverse measurements and the variables of skeletal age and sex. Results: Sex was a significant explanatory factor for all transverse variables. In the postpubertal and postspurt stages, all transverse measurement values were found to be higher in males. Postpubertal term was a significant explanatory factor for maxillary, mandibular, mandibular intermolar, and maxillary intermolar widths, whereas pubertal term was only a significant explanatory factor for maxillary intermolar width. Conclusion: Skeletal age and sex should be taken into account when determining transverse dentofacial measurements.   How to cite this article: Sezen Erhamza T, Akan B, Nazik Ünver F, Evli Dalgalı P.
