Objective: To evaluate the stages of midpalatal suture (MPS) maturation in patients older than 15 years, and to determine the correlation between the stage of MPS maturation and age and cervical vertebral maturation (CVM). Materials and Method: Cone-beam computed tomography (CBCT) scans of 50 patients (29 female and 21 male; mean age, 19.79 ± 4.09 years) were evaluated. Good quality CBCT images from 15–30-year-old patients for evaluation of impacted canines or determination of orthognathic surgery were selected. The CBCT images were evaluated at two different time intervals for determination of the stages of MPS and CVM. The stages of MPS maturation were classified as A, B, C, D, or E using the axial sections by using a method validated previously. The stages of CVM were classified using sagittal sections of the CBCT images. Intra-examiner agreement was assessed using the Kappa test. The correlations between MPS maturation and chronological age and CVM were assessed using Spearman’s rank correlation analysis. Results: The Kappa coefficients for intra-examiner agreement were 0.837 and 0.865 for classification of the stages of MPS maturation and CVM, respectively. No significant correlation was observed between chronological age and maturation of MPS (r = 0.212, p = 0.139) and between the stages of CVM and maturation of MPS (r = 0.030, p = 0.839). Conclusion: The limitation of our study was a small sample size, and, on the basis of our results, neither CVM nor chronological age could be used as a convenient tool to determine the stage of MPS maturation in 15–30-year-old patients.

The assessment of facial growth and development is important to determine the optimal timing for different treatment procedures in the growing patient. Many skeletal maturity indicators have been proposed over previous years because chronologic age is not sufficient alone for assessing the stage of development in a growing child. Maturational status has been traditionally evaluated by hand-wrist radiographs which are considered the gold standard. Different radiographic methods have been evaluated for their correlation with the skeletal maturity, and simple and practical alternatives to the hand-wrist radiograph have been presented. In accordance with the ALARA (As Low As Reasonably Achievable) principle, if evaluation of skeletal age is indicated, it is important to take radiographs with the lowest dose. The objective of this review was to evaluate different methods for assessing skeletal maturity in dentistry.

Human growth and development are depended on both genetic and environmental conditions. From infancy to adulthood, during the growth process the growth rate of the body ratios shows differences. The purpose of the present study is to evaluate height, upper arm, forearm, upper leg, lower leg length values of the pre-school children and to determinate the ratios, and contribute to other public health studies. The study sample consisted of 815 (402 male, 413 female) children aged between 3 and 5 years living in Ankara. Height, upper arm, forearm, upper leg, and lower leg lengths were taken in accordance with the standard protocols after receiving ethical and family permits. The statistical analyses conducted using SPSS 20.0 program and percentiles were constructed using LMS method. According to the results, children aged between 3 to 5 years, the forearm / upper ratio was 0.8 and the lower / upper ratio was 0.7 in both sexes. Positive correlation was found between all variables (p <0.001). The comparison of study results with other country values revealed that upper arm length was lower than the American children (Centers for Disease Control and Prevention (CDC)) for the respective age groups. Constructing the country specific reference values is of great importance for to follow-up children's development, to evaluate and compare for further generations and to determinate the secular changes.
