The aim of the study was to find a correlation between the evaluation of skeletal maturation performed by the study of cervical vertebrae maturation indicators and the evaluation obtained by the hand and wrist maturation indicators.
Left hand wrist radiographs and the corresponding lateral cephalograms of 90 patients (48 males and 42 females; aged 6 to 14 years) were paired and a study group of 128 pair of radiographs was obtained, having some patients 2 or more radiographs at different times. Hand and wrist radiographs were evaluated according to the protocol proposed by Grave (scores 0 to 9); corresponding lateral cephalograms were evaluated according to the method reported by Baccetti (scores 1 to 5). Values obtained with the 2 methods were analyzed by Spearman's correlation test.
When the values were compared globally in the 2 genders a good correlation was obtained (r=0.795; P<0.001); when the correlation was compared separately in the 2 genders a better correlation was observed in females (r=0.84; P<0.001) than in males (r=0.70; P<0.001).
The results obtained clearly underline the accuracy of the skeletal maturation evaluation by the analysis of cervical vertebrae in laterolateral cephalograms which can substitute the hand and wrist radiograph for the skeletal maturation evaluation in orthodontic diagnosis.
本研究旨在探寻通过颈椎成熟度指标评估骨骼成熟度与通过手部及腕部成熟度指标评估所得结果之间的相关性。
将90例患者（48例男性和42例女性；年龄6至14岁）的左手腕部X光片与相应的头颅侧位片进行配对，共获得128对X光片组成的研究组，部分患者在不同时间有2张或更多X光片。手部及腕部X光片根据Grave提出的方案进行评估（评分0至9分）；相应的头颅侧位片根据Baccetti报道的方法进行评估（评分1至5分）。用Spearman相关性检验分析两种方法所得的值。
在对两种性别总体比较时，获得了良好的相关性（r = 0.795；P < 0.001）；当分别比较两种性别的相关性时，女性（r = 0.84；P < 0.001）的相关性比男性（r = 0.70；P < 0.001）更好。
所得结果清楚地表明，通过分析头颅侧位片中的颈椎来评估骨骼成熟度具有准确性，在正畸诊断中，它可以替代手部及腕部X光片用于骨骼成熟度评估。
