Introduction : Skeletal age assessment by hand-wrist radiographs has been found to correlate significantly with the growth status of an individual but has a known drawback in the form of extra radiograph and high dose of radiation exposure in comparison to periapical X-rays used commonly in dentistry. Aims and objectives: The purpose of the study was to assess skeletal age using hand-wrist as well as periapical radiographs of maxillary and mandibular canine and to find the correlation among the skeletal, dental and chronological ages. Materials and methods: Ninety Indian healthy children in the age group 9 to 13 years, comprising equal number of males and females were included in the study. The children were radiographed for hand-wrist of the right hand and intraoral periapical X-ray for right permanent maxillary and mandibular canine. Results: There was high correlation between skeletal maturation indicator and canine calcification for both male and female (0.635, 0.891). Conclusion: Females were more advanced in skeletal maturation than males. Chronological age showed inconsistent correlation with dental and skeletal ages. It was concluded that canine calcification stages can also be used for assessing skeletal maturity.
