Assessment of bone age by cervical vertebral dimensions in lateral cephalometric radiographs
Journal Title: Journal of Oral Medicine, Oral Surgery, Oral Pathology and Oral Radiology - Year 2018, Vol 4, Issue 3
Abstract
Aim and Objectives For determining the skeletalbone age from handwrist radiographs Greulich and Pyles Atlas and TannerWhitehouse 3 TW3 methods are considered as reliable methods but there are concerns of extra radiation dose The cervical vertebral bone age CVBA by measurements of the vertebral body of third C3 and fourth C4 is a relatively new method of objectively evaluating the skeletal maturation The aim of this study was to estimate bone age by measuring 3rd and 4th cervical vertebral C3 C4 dimensionsMaterials and Methods Lateral cephalometric and handwrist radiographs of 40 male and 46 female subjects 0816 years of age who had attended Government Dental College Srinagar for treatment were taken and measurements of C3 and C4 was done by using NNT Dicom version 7000 software Handwrist bone age was determined using Pyle and Greulich Atlas Stepwise multiple regression analysis demonstrated the correlation between the measurementsResults Anterior height of the third cervical vertebrae AH3 in males had the strongest correlation with handwrist bone age r1o p3 was 10733 The highest correlation coefficient in females was observed between H3 and the estimated bone age from Greulichs Atlas r0896 p3 was 1043 The bone age was calculated by multiple regression model Bone age in males 0809AH3 2896 Adjusted R2 was 0153 p3 2752 Adjusted R2 was 0245 pConclusions Lateral cephalometric radiographs might be an alternative to the handwrist radiography for bone age estimation Therefore analysis of cervical vertebrae by replacing handwrist method additional radiograph could be avoidedKeywords Cervical vertebral bone age Lateral cephalometric radiographs Handwrist radiographs
