    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.

    Identification of Maxillofacial Problems in Extraoral Photographs by Panel Members: A Pilot Study
    (Aves, 2019) Kilicaslan, Yagmur; Erhamza, Turkan Sezen; Ozdiler, Ferabi Erhan
    Objective: The aim of this pilot study was to evaluate the effectiveness of the profile and frontal photographs in determining sagittal maxillofacial problems by the panel members created from different professional groups. Methods: Frontal and profile photographs of four individuals with skeletal Class I, Class II Division 1, Class II Division 2, and Class III malocclusion were assessed by panel members. A total of 42 panel members from 7 different professions participated in the study. Panel members were asked to choose one of the frontal or profile photographs to be used in determining the maxillofacial problem. Mann-Whitney U test, Kruskal-Wallis test, and Fisher's exact test were applied to evaluate the difference between the panelists. Results: Of the 42 panel members, 16% selected frontal photographs, and 84% selected profile photographs. There were no statistically significant differences between seven panels with regard to photography selection (p>0.05). When all panel members were compared with regard to gender, 17.9% of the frontal photographs and 82.1% of the profile photographs were selected by females, whereas 15.4% of the frontal photographs and 84.6% of the profile photographs were chosen by males. There was no statistically significant difference between males and females (p>0.05). Conclusion: It was found that the profile photograph was more preferred and informative in determining the sagittal maxillofacial problem.
