Skeletal Maturation Using Cervical Vertebrae Versus Dental Age For Age Estimation

Summary Background The prevalence of childhood and adolescent obesity is increasing worldwide. Reports suggest that elevated body mass index (BMI) is associated with larger craniofacial dimensions and advanced dental and skeletal development. Such an association is important for timing orthodontic treatment relative to pubertal growth and dental eruption. Materials and Methods To evaluate associations between BMI, craniofacial morphology, dental age, and cervical vertebrae maturation staging (CVMS), 400 participants were consecutively selected (8–15 years, n = 200 overweight and obese BMI >85%, 200 normal weight) from the University of North Carolina database. Records were analysed for cephalometric measures, Demirjian index values, and CVMS. Bivariate statistics and linear regression analysis evaluated whether CVMS, dental age, and cephalometric dimensions varied with BMI. Results Overweight/obese children and adolescents had a proportionally larger bimaxillary prognathic skeletal pattern compared to those of normal weight. These cephalometric measurements [articulare–gnathion (Ar–Gn), condylion–anterior nasal spine (Co–ANS), sella–gonion (S–Go), nasion–menton (N–Me), anterior nasal spine–menton (ANS–Me), sella-nasion-A point (SNA), sella-nasion-B point (SNB), and sella-nasion-pogonion (SNPg)] were significantly different [statistically (P < 0.05) and clinically (>2 mm or >2 degrees)] between the two study groups, with a linear relationship between BMI percentile and craniofacial dimension. The overweight/obese BMI group had a mean dental age 1.4 years advanced relative to the normal weight group (P < 0.05), with an advancement of nearly one CVM stage between the ages of 12 and 14 (P < 0.05). Limitations The study is retrospective. Conclusions Obese/overweight children and adolescents have proportionally larger antero-posterior and vertical dimensions and are more likely to experience advanced dental and skeletal maturation. Obese/overweight subjects may enter their growth spurt at a younger age and have earlier eruption of teeth, affecting treatment timing. BMI percentile should be a consideration for orthodontic treatment in growing patients.

Abstract Background: Dental age assessment is very useful in the pediatric dentist’s and orthodontist’s everyday practice. The eventual lack of correlation between dental age, skeletal maturation and chronological age can influence treatment procedures regarding mostly their application time. The aim of our study was to investigate the relationship between dental age based on the calcification stages of the first lower premolar (PM1i) and skeletal maturity stages using cervical vertebrae (C2, C3, C4) among Romanian individuals and to determine the clinical value of the first premolar as a growth evaluation index. Material and methods: In a sample of 30 patients (13 males, 17 females) ranging in age from 9 to 15 years (mean age 11.2 years) we examined the orthopantomography radiographs (OPT) and lateral cephalometric radiographs of each case. Results: The biological development of girls is about 1.5 years more advanced than in boys. When the Demirjian Index was at stage F, then CVS was at stage 3.4, which means that in developmental stage “F” (according to Demirjian index) premolars are indicators of the optimal time for orthodontic treatment. We found a significant correlation (R = 0.871, p <0.001) between CVM and Demirjian's index. Conclusions: The correlation shown in this study will allow clinicians to use mandibular first premolar as an adjunctive tool to assess adolescent growth spurt, combined with the evaluation of the cervical vertebrae. The results also show the usefulness of the assessment of the development of dental status as a simple diagnostic test to determine the biological age of the population

Objectives: To compare Demirjian Dental scoring method with Greulich-Pyle (GP) Skeletal method of age estimation in pubertal children. Materials and Methods: Sample of the study included 267 male healthy subjects of 11-16 years of age group.. Demirjian Scoring system was utilized to evaluate the orthopantomograms to assess their Dental age and the Hand-Wrist radiographs were analyzed to calculate the skeletal age by utilizing GP atlas. Chronological age was obtained from the date of birth of the subject .Both methods were compared with one another and with the chronological age. It was a cross-sectional study and only healthy male subjects without any clinical abnormalities were included in the study. Results: A total of 267 male subjects of 11-16 years of age group were assessed by Demirjian and Greulich Pyle Methods. Both were compared with Chronological Age. Data obtained was statistically analyzed and the Student “t” test was applied in the study population. The mean difference between Chronolgical age and dental age was 0.69years and that of chronological age and skeletal age was 0.87 years. It was observed from dental age assessment that it does not differ much from the skeletal age. Conclusion: It was concluded that Demirjian method of Age Estimation is more precise than Greulich Pyle method of Age Estimation. Furthermore both methods can be used selectively in Medicolegal cases to access bone age which can be easily correlated to chronological age.
