Human growth shows considerable variation. In addition to constitutional differences in the timing of maturation, there are diseases, systemic disorders and environmental factors that may affect a child's physiologic maturity. Interrelationships among skeletal, somatic and sexual maturity have been shown to be consistently strong. The study was conducted to evaluate the relationship between dental calcification stages and skeletal maturity indicators.
The hand wrist radiographs, the lateral cephalogram and the orthopantomogram (OPG) of 120 patients (60 males and 60 females, age group 8-14 years) were taken. The hand wrist radiographs were analyzed using Fishman's skeletal maturity index (SMI), and the cephalograms analyzed by cervical vertebrae maturation (CVM) by Baccetti. OPG was analyzed according to the Demirjian's system.
On assessment, cervical vertebrae maturation indicator (CVMI) staging showed significant results with a correlation coefficient of 0.716 being the highest in canines in males while assessment of dental calcification stages and its comparison with skeletal maturity indicator showed insignificant results. The correlation coefficient values were 0.11, 0.09, 0.09 and 0.13 for canine, first premolar, second premolar and second molar respectively.
There is a strong correlation between the maturation stage of cervical vertebrae and calcification stages of canine, first premolar, second premolar and second molar as determined by Demirjian's method.
人类生长存在显著差异。除了成熟时间的体质差异外,还有疾病、全身性疾病和环境因素可能影响儿童的生理成熟度。骨骼、身体和性成熟之间的相互关系已被证明始终很强。本研究旨在评估牙齿钙化阶段与骨骼成熟指标之间的关系。
拍摄了120例患者(60例男性和60例女性,年龄8 - 14岁)的手腕部X光片、头颅侧位片和口腔全景片(OPG)。手腕部X光片采用菲什曼骨骼成熟指数(SMI)进行分析,头颅侧位片由巴切蒂的颈椎成熟度(CVM)进行分析。OPG根据德米尔坚系统进行分析。
评估时,颈椎成熟度指标(CVMI)分期显示出显著结果,男性犬齿的相关系数最高为0.716,而牙齿钙化阶段的评估及其与骨骼成熟指标的比较显示出不显著结果。犬齿、第一前磨牙、第二前磨牙和第二磨牙的相关系数值分别为0.11、0.09、0.09和0.13。
根据德米尔坚方法确定,颈椎成熟阶段与犬齿、第一前磨牙、第二前磨牙和第二磨牙的钙化阶段之间存在很强的相关性。
