Accuracy of skeletal maturation with chronological age and gender of children aged 7 – 15 Years

Background: Skeletal maturation has been used as a way to evaluate growth and development and its accuracy with the chronological age of a child. Cervical Vertebrae Maturation method (CVM), assessing changes in the concavity of the inferior border and the shape of the cervical vertebrae C2, C3, C4 which is currently a reliable method. The aim of this study is to analyze the accuracy of skeletal maturation by chronological age and gender in children Aged 7-15 Years.

Material and methodology: Cross-sectional study using cephalometrics radiographs of 100 children who were recently undergoing dentoskeletal treatment at the Pediatric Dental Specialist Clinic, RSKGMP Universitas Airlangga Surabaya, 54 girls (mean age 10.91±2.09) and 46 boys (mean age 10.49±1.84) in the age group 7-15 years. Skeletal maturation was analyzed using the Cervical Vertebrae Maturation method by Baccetti. Statistical analysis to examine the differences between chronological age and skeletal maturation using Mann-Whitney.

Results: There was a significant difference (p<0.05) in skeletal maturation between boys and girls in the age group 12-12.9 (p=0.02) and 13-13.9 (p=0.01) years.

Conclusion: Skeletal maturation differs in boys and girls with girls maturing earlier.
