Objective: The present study consists of comparison and correlation between the hand-wrist skeletal maturation indicator (SMI) and the cervical vertebral maturation indicator (CVMI) and verification of the reliability of the vertebral index and chronological age in the determination of the stages of the skeletal maturation. Materials and Methods: The study consisted of randomly selected 90 children from Lucknow population with 45 males (age range 10-13 years) and 45 females (age range 9-12 years). Hand wrist radiograph taken for SMI, Lateral cephalogram taken for CVMI. Correlation was made between cervical vertebrae maturation and hand wrist maturation. These two methods and the chronological age were compared using the Newman-Keuls test. Results: There was strong correlation between SMI and CVMI for both male and female (0.849, 0.932). Cervical vertebrae maturation indicator and hand-wrist skeletal maturational indicator (SMI) showed no statistical signi?cant difference for males and females. However, females showed maturation at an early age as compared to males. Chronological age shows significant difference in comparison to skeletal age. Conclusion: It was concluded that CVMI stages can also be used as for assessing skeletal maturity. Cervical vertebrae assessment provided a reliable assessment for pubertal growth spurt, it would be bene?cial to use a lateral cephalogram for skeletal maturity assessment and thereby eliminate the need for an additional radiograph (hand-wrist radiograph). This is cost effective and will also reduce the radiation exposure to the patient.
