Aim:
To develop and validate a reliable, objective method for cervical vertebral bone age (CVBA) estimation using lateral cephalograms in a Maharashtrian population.
Methods:
Gender-specific formulae for cervical vertebral bone age estimation were derived via stepwise regression using C3/C4 measurements from lateral cephalograms of 1000 participants 1000 participants (500M/500F, 9-20 years). Formulae were validated on an independent sample (100M/100F). Hand-wrist radiographs were assessed using the Tanner-Whitehouse 3 (TW3) method. CVBA, TW3 bone age, and chronological age were compared using ANOVA, Tukey's test, and Pearson correlation.
Result:
Gender-specific CVBA formulae were generated. No significant differences were found between CVBA, TW3 bone age, and chronological age for males (P=0.393) or females (P=0.656). High correlations existed between CVBA, TW3 bone age, and chronological age.
Conclusion:
The derived formulae are valid and reliable for objective assessment of cervical vertebral bone age and skeletal maturation using lateral cephalograms in the studied Maharashtrian population.

Hormones and Bone Tissue
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
