Skeletal age had been assessed by comparison between maturation of hand-wrist with stages of cervical vertebrae or canine calcification stages in past and this had been closely related to craniofacial growth. The importance of pubertal growth spurt in various types of orthodontic therapies is already established.
Hence, this study was aimed to evaluate the relationship of skeletal maturity by hand-wrist with cervical vertebral maturation indicators and canine calcification stages.
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). Lateral Cephalogram, hand-wrist x-ray, and periapical x-rays of maxillary and mandibular right canines were taken.
Mean, standard deviation was calculated of different groups. Correlation was made among cervical vertebral maturation, hand wrist maturation, and canine calcification stages at various age groups.
There was strong correlation between skeletal maturation indicator and cervical vertebral maturation indicator for both male (0.849) and female (0.932), whereas correlation between skeletal maturation indicator and canine calcification was good for both male and female (0.635, 0.891).
It was concluded that cervical vertebral maturation indicator and canine calcification stages can also be used for assessing skeletal maturity.
过去曾通过比较手腕成熟度与颈椎阶段或犬齿钙化阶段来评估骨骼年龄，这与颅面生长密切相关。青春期生长突增在各种正畸治疗中的重要性已经得到确立。
因此，本研究旨在评估手腕骨骼成熟度与颈椎成熟指标及犬齿钙化阶段之间的关系。
该研究由从勒克瑙人群中随机选取的90名儿童组成，其中45名男性（年龄范围10 - 13岁），45名女性（年龄范围9 - 12岁）。拍摄了头颅侧位侧侧位片、手腕X线片以及上颌和下颌右侧犬齿的根尖片。
计算了不同组的均值、标准差。对各年龄组的颈椎成熟度、手腕成熟度和犬齿钙化阶段进行了相关性分析。
男性（0.849）和女性（0.932）的骨骼成熟指标与颈椎成熟指标之间均存在强相关性，而男性和女性的骨骼成熟指标与犬齿钙化之间的相关性均良好（分别为0.635和0.891）。
得出的结论是，颈椎成熟指标和犬齿钙化阶段也可用于评估骨骼成熟度。
