The aim of this study was to assess the correlation between the Fishman maturation prediction method (FMP) and the modified version of the cervical vertebral maturation (CVM) method proposed by Baccetti for skeletal maturation stage determination. Hand-wrist and lateral cephalograms from 90 subjects (27 females and 63 males) were used. Hand-wrist radiographs were analyzed using the FMP to determine skeletal maturation level (advanced, average, or delayed) and stage. Cervical vertebrae (C2, C3, and C4) outlines obtained from lateral cephalograms were analyzed using the CVM to determine skeletal maturation stage. Results show that the MP3cap stage was related significantly with CS3 and CS4 stages in 92.85%. A Spearman correlation value of 0.90 was found between the skeletal maturation stages of both methods (P < .001) . When the sample was subgrouped according to skeletal maturation level, the following correlation values were found: for early mature adolescents 0.94, for average mature adolescents 0.90, and for late mature adolescents 0.94.
Correlation values between both skeletal maturation methods were high and significant. The skeletal level does not influence in the values of correlation.
