    Effect of body mass index percentile on skeletal maturation of cervical vertebrae and hand-wrist and dental maturation
    (TAYLOR & FRANCIS LTD, 2020) Erhamza, Turkan Sezen; Kilicaslan, Yagmur; Unver, Fatma Nazik
    Objective: The aim of this study was to evaluate the relationship between age- and gender-specific body mass index (BMI) percentile and skeletal and dental maturation in Turkish adolescents. Materials and methods: A sample of 429 patients (171 males, 258 females aged between 7 and 17 years) was selected. Skeletal maturation was identified in the hand-wrist radiography by Bjork, Grave and Brown (BGB), and the cervical vertebrae maturation (CVM) method defined by Hassel and Farman in lateral cephalometric radiography. Dental maturation was determined by the Demirjian method. BMI was calculated by reference curves used for Turkish children. A regression model was used for the relationship between BMI percentile and skeletal and dental maturation. Results: There was no significant correlation between BMI and skeletal maturation of cervical vertebrae and dental maturation. A one-percentile increase in BMI percentile accelerates the increase of period (likelihood of being post-pubertal period) to 1.016 times (p < .05). Skeletal maturation of hand-wrist and cervical vertebrae and dental maturation were more prominent in females compared to males (p < .05). Males and females were not statistically significantly different in BMI percentile (p = .52). Conclusions: BMI may be considered before deciding to estimate the skeletal and dental maturation in an individual by the relevant methods.

    Transversal craniofacial development between skeletal maturation stages: A multi-center posteroanterior cephalometric study
    (Scientific Scholar Llc, 2022) Erhamza, Turkan Sezen; Akan, Burcin; Cigerim, Saadet Cinarsoy; Korkmaz, Yasemin Nur; Unver, Fatma Nazik
    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. Material 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 Bjork, 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 SMSs. 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.
