The present method of skeletal maturity assessment like handwrist or cervical vertebrae radiographies are expensive, require elaborate equipment and account for high radiation exposure, especially for growing children. This study tried to consider the value of the 2nd primary molar in growth stage. Material and Method: 40 samples aged 8-13 were tested by their panoramic and handwrist radiographs. Result and Conclusion: there was a coincidence between presence calcified sesamoid and 2nd primary molar as the last tooth. The result showed that it could be a reliable index to predict the growth stage in 1st visit without radiography.
