An essential part of pediatric dentistry in recent times is age estimation for various purposes such as orthodontics, forensic dentistry, human anthropology, and bioarchaeology. Assessment of calcification of dental tissue is another physiologic method for skeletal growth assessment.
This study aims to evaluate the correlation between dental calcification stages and skeletal maturity indicators and their application in age estimation purposes.
Tooth calcification was assessed by Demirjian's method and hand-wrist assessment was done by Fishman's method. Spearman's rank-order correlation coefficient was applied to measure the association between skeletal maturational indicators and dental calcification stages of individual teeth, and the statistical significance of the correlation was tested.
Spearman's significant coefficients for canine, first premolar, second premolar, and molar are 0.11, 0.09, 0.09, and 0.13, respectively, which are not significant.
Fishman's method of hand-wrist radiograph assessment is quite accurate as a maturity indicator but its association with dental calcification stages cannot be established.
近年来，儿童牙科的一个重要部分是出于正畸、法医牙科、人类人类学和生物考古学等各种目的进行年龄估计。评估牙齿组织的钙化是评估骨骼生长的另一种生理方法。
本研究旨在评估牙齿钙化阶段与骨骼成熟指标之间的相关性及其在年龄估计中的应用。
采用德米尔坚法评估牙齿钙化，并采用菲什曼法进行手腕部评估。应用斯皮尔曼等级相关系数来测量个体牙齿的骨骼成熟指标与牙齿钙化阶段之间的关联，并检验相关性的统计学意义。
犬齿、第一前磨牙、第二前磨牙和磨牙的斯皮尔曼显著系数分别为0.11、0.09、0.09和0.13，均无统计学意义。
菲什曼手腕部X线片评估方法作为成熟指标相当准确，但无法确定其与牙齿钙化阶段的关联。
