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.

INTRODUCTION: Biological age is an important parameter for growth and development assessment. It can be evaluated through the observation of radiographic changes in skeletal maturation of cervical vertebrae. OBJECTIVE: This study aims to: a) verify if there is correlation between growth curve and the stages of bone age of animals used in laboratories, by evaluating radiographs of the cervical vertebrae; b) correlate these stages with their correspondents in humans. METHODS: 35 Wistar rats were evaluated for a period of 160 days, starting at day 22nd (weaning), with cross sections for periodic weighing, length measurement and digital radiography. Radiographs of the cervical vertebrae (C2 and C3) were measured by means of a computer program (Radio IMP). Data were submitted to statistical analysis (ANOVA) and Pearson correlation. RESULTS: Growth spurt was characterized by fast increasing in weight and length. Through ANOVA, differences were observed in the cervical measurements between days 22, 97, 127, 157, 187 and 217 (p <0.001). A high correlation was found between increasing in body length and weight, as well as in cervical vertebrae height (r = 0.86). Increments in concavities of vertebrae were also observed, similar to humans. CONCLUSIONS: There is correlation between body growth and maturation of cervical vertebrae in rats. Despite the continuous development of concavities, it was not possible to clearly identify the 5/6 stages as in studies of cervical vertebrae maturation in humans.

Objectives: To investigate the relationship between cervical vertebrae maturation and mandibular second molar calcification stages.Study design: The study was designed as a retrospective, descriptive and crosssectional research project. Pre-treatment lateral cephalograms and panoramic radiographs of 99 males and 110 females in the age range of 7 to 18 years 7 months were evaluated with Demirjian Index (DI) and cervical vertebrae maturation indicators (CVMI) of Hassel and Farman. A null hypothesis was proposed that there is no relation between CVMI and DI. Results: A highly significant association (Pearson's contingency coefficient 0.713 for males and 0.863 for females) was found between DI and CVMI. In males, the DI stage E corresponded to stage 2 of CVMI (pre–peak of pubertal growth spurt) and DI stages F and G corresponded to stages 3 and 4 of CVMI (peak of pubertal growth spurt). DI stage H was associated with stages 5 and 6 of CVMI (end of pubertal growth spurt). In females, the DI stages C, D corresponded to CVMI stages 1, 2; DI stages E, F with CVMI stages 3, 4; DI stages G, H with CVMI stages 5, 6. Conclusion: Mandibular second molar calcification stages can be used as indicators for assessment of skeletal maturity.

ABSTRACT Aim The aim of this study was to establish the validity of a new method for evaluating skeletal maturation by assessing the 3rd and 4th cervical vertebrae seen in the cephalometric radiograph. Materials and methods This study consisted of a sample of 50 patients in the age group of 8 to 14 years of age. Chronologically, they were divided into six groups, based on the age consisting of a minimum of six to a maximum of 10 subjects. All the patients included in the study were females. The selected subjects were clinically examined and then age and date of birth of the patient in years and months was noted. Then lateral cephalograms and hand-wrist radiographs of the patient were taken on the same day with good clarity and contrast. Results The results suggested that cervical vertebral bone age on cephalometric radiographs calculated with this method is as reliable at estimating bone age as is the Tanner-Whitehouse 3 (TW3) method on hand-wrist radiographs. By determining the cervical vertebral bone age, skeletal maturity can be evaluated in a detailed and objective manner with cephalometric radiographs. Conclusion The ability to accurately appraise skeletal maturity from cervical vertebral maturation, without the need for additional radiographs, has the potential to improve orthodontic diagnostic and therapeutic decisions. The technique's simplicity and ease of use should encourage this method as a first level diagnostic tool to assess skeletal maturation. Clinical significance This study revealed that the timing and sequence of ossification of the bones in hand and wrist and cervical vertebrae were able to relate the skeletal development of the various skeletal maturity indicators to a child's development. This method provided a mean with which one can determine the skeletal maturity of a person and thereby determine whether the possibility of potential growth existed.

Objectives: This study aimed to assess the skeletal maturation by using salivary DHEAS levels and its correlation with existing skeletal maturity parameters represented by cervical vertebrae and MP3 region radiographs in adolescents in pre-pubertal and pubertal age groups. Methods: In this study, 80 children in the age range of 8 - 14 years were divided into two equal groups based on their chronological age as group I (pre-pubertal group) and group II (pubertal group). Pre-existing lateral cephalograms and medial phalanx of third finger (MP3) radiographs of their left hands were assessed. The levels of the DHEAS of each individual were analysed by ELISA kit. ANOVA with post-hoc Tukey’s test and student t-test were used for statistical analysis. P-value < 0.05 was considered significant. Results: The mean level of DHEAS values shown in the present study was 4.36 +/- 0.32 ng/mL in group I and 5.73+/-0.39 ng/mL in group II. This study showed that in group I, more subjects were in stage 1 of cervical vertebral maturation than stage 2 and there were significant differences between the two stages (P-value = 0.011); also, in group II, more subjects were in stage 3 than 4 and there were significant differences between the two stages (P-value = 0.017). This study revealed the highest salivary DHEAS levels to be in the F stage of pre-pubertal MP3 development in addition to the H stage of MP3 development in pubertal children. This study noted that there were significant differences for salivary DHEAS levels between males and females not only in pre-pubertal (P-value = 0.031), but also in pubertal stages (P-value < 0.001). Conclusions: Salivary DHEAS, like cervical vertebra and MP3 radiographs, can be used for growth assessment in young adolescents.

This study aimed to determine the correlation between the volumetric parameters derived from the images of the second, third, and fourth cervical vertebrae by using cone beam computed tomography with skeletal maturation stages and to propose a new formula for predicting skeletal maturation by using regression analysis. We obtained the estimation of skeletal maturation levels from hand-wrist radiographs and volume parameters derived from the second, third, and fourth cervical vertebrae bodies from 102 Japanese patients (54 women and 48 men, 5–18 years of age). We performed Pearson’s correlation coefficient analysis and simple regression analysis. All volume parameters derived from the second, third, and fourth cervical vertebrae exhibited statistically significant correlations (P<0.05). The simple regression model with the greatest R-square indicated the fourth-cervical-vertebra volume as an independent variable with a variance inflation factor less than ten. The explanation power was 81.76%. Volumetric parameters of cervical vertebrae using cone beam computed tomography are useful in regression models. The derived regression model has the potential for clinical application as it enables a simple and quantitative analysis to evaluate skeletal maturation level.

Chronological age conveys only a rough approximation of the maturational status of a person whereas skeletal maturity indicators give a more accurate estimation. Therefore, it is of interest to document the correlation between chronological and skeletal age using CVMI and modified MP3 methods. A total of 39 subjects between the age ranges of 9-16 years were selected for this study. Pre-treatment lateral cephalograms and hand-wrist radiographs of the subjects were used. The skeletal age was analyzed by the Cervical Vertebrae Maturity Index (CVMI) and modified MP3 methods. The data was analyzed with SPSS software version 23.00. Kendall’s Tau correlation test was performed to estimate the correlation between chronological age and skeletal age among the subjects and a linear regression test was also performed. Positive correlation was found between chronological age and skeletal age assessed by CVMI method (r= 0.398) and modified MP3 method (r=0.382) with p value <0.003. Thus it can be concluded that there was a positive correlation between chronological age and skeletal age among all the subjects.
