The purpose of the study was to assess skeletal age using MP3 and hand-wrist radiographs and to find the correlation amongst the skeletal, dental and chronological ages. One hundred and sixty North-Indian healthy children in the age group 8-14 years, comprising equal number of males and females were included in the study. The children were radiographed for middle phalanx of third finger (MP3) and hand-wrist of the right hand and intra oral periapical X-ray for right permanent maxillary canine. Skeletal age was assessed from MP3 and hand-wrist radiographs according to the standards of Greulich and Pyle. The dental age was assessed from IOPA radiographs of right permanent maxillary canine based on Nolla's calcification stages. Skeletal age from MP3 and hand-wrist radiographs shows high correlation in all the age groups for both sexes. Females were advanced in skeletal maturation than males. Skeletal age showed high correlation with dental age in 12-14 years age group. Chronological age showed inconsistent correlation with dental and skeletal ages.
本研究的目的是使用第三指中节指骨（MP3）和手腕部X光片评估骨龄，并找出骨龄、牙龄和实足年龄之间的相关性。本研究纳入了160名年龄在8至14岁之间的北印度健康儿童，男女数量相等。对这些儿童的右手第三指中节指骨（MP3）和手腕部进行X光拍摄，并对右上颌恒尖牙进行口腔内根尖周X光拍摄。根据格吕利希和派尔的标准，从MP3和手腕部X光片评估骨龄。根据诺拉的钙化阶段，从右上颌恒尖牙的口腔内根尖周X光片评估牙龄。MP3和手腕部X光片的骨龄在所有年龄组的男女中均显示出高度相关性。女性的骨骼成熟度比男性高。在12至14岁年龄组中，骨龄与牙龄显示出高度相关性。实足年龄与牙龄和骨龄的相关性不一致。
