Correlation of Two Radiographic Methods of Skeletal Maturation Stages Determination in Skeletal Class II Malocclusion Patients at Puberty
Aim: The purpose of this comparative study was to evaluate the correlation between two radiographic methods used to evaluate skeletal maturation, hand-wrist analysis method and cervical vertebrae analysis method, of skeletal Class II malocclusion patients at puberty growth spurt.
Materials and Methods: Digital Hand-wrist radiographs and digital lateral cephalograms from 37 Syrian adolescent untreated skeletal Class II patients (19 females and 18 males) at puberty averaged 13.12 years were obtained. Skeletal maturation stage of each hand-wrist radiographs were evaluated using the method described by Fishman, whereas skeletal maturation stage of cervical vertebrae were evaluated using the method described by Hassel and Farman. To define the relationship between the two used method, Spearman's correlation coefficient was calculated.
Results: The number and percentage of patients were calculated according to the SMI and CVMI indices. The skeletal maturation index (SMI) stages and cervical vertebrae maturation index (CVMI) stages were not related, and Spearman's correlation coefficient was found to be not statistically significant (rs = 0.25, P > 0.05).
Conclusion: Within the limits of this study, the cervical vertebrae maturation method might mislead the clinician when treating adolescent skeletal Class II patients at the pubertal growth spurt since it is not correlated with hand wrist skeletal maturation method.
