Abstract

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. Kendallís 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.
