Objective : The assessment of skeletal maturation is of prime importance in diagnosis, treatment planning and retention after orthodontic treatment. This study was contemplated to find the correlation of improved version (CVMS) with older version (CVMI) of cervical vertebral maturation indicator and to correlate both these methods to stages of ossification of middle phalanx of third finger (MP3) and calcification stages of mandibular canine. Materials and methods: The radiographs of 80 healthy children (40 males and 40 females) between the age group of 10 and 15 years were taken to assess the CVMS and CVMI stages using lateral cephalogram, stages of MP3 and the stages of development of mandibular right canine using dental (IOPA) X-ray film. Skeletal maturation was assessed from MP3, CVMS, CVMI and dental maturation was determined by Demirjian method. Results: Overall, high significant correlation was found between CVMI and CVMS (r = 0.994) and lowest significant correlation was found between CVMS and DeMI (r = 0.653). Association between CVMS and CVMI indicated that stages 1, 2, 3 of CVMI correlated directly with CVMS 1, 2, 3; stages 4/5 of CVMI correlated with stage 4 of CVMS, and stage 6 of CVMI with stage 5 of CVMS. Conclusion: The correlation between middle phalanx of 3rd finger (MP3) and cervical vertebral maturation method (CVMI and CVMS) was higher as compared to the correlation of either of the cervical vertebral maturation method or MP3 with dental maturation indicator.
