The relationship between early radiographic evidence of calcification of the adductor sesamoid of the first metacarpophalangeal joint and the state of maturity of certain teeth was investigated. Data were obtained from the records of one hundred and forty children of Caucasoid origin, comprising ninety-three girls and forty-seven boys. Calcification of the adductor sesamoid was closely related to the completion of root mineralization of the mandibular canine prior to apical closure. No significant sex differences were noted in the state of maturation of the tooth in relation to this particular stage of skeletal development. Correlations among the remaining teeth studied were low, the distribution of calcification stages being widely dispersed with significant sex differences evident. Based on the findings of this study, the completion of root formation of the mandibular canine prior to apical closure may be used as a maturity indicator for the commencement of the circumpubertal growth spurt with a similar degree of confidence as the calcification of the adductor sesamoid of the thumb. It should be noted, however, that racial variations might exist in the relationship between the state of maturity of this tooth and the commencement of mineralization of the sesamoid. Caution should thus be exercised in the application of these findings to other racial groups.
研究了第一掌指关节内收籽骨早期钙化的影像学证据与某些牙齿成熟状态之间的关系。数据来自140名高加索裔儿童的记录，其中包括93名女孩和47名男孩。内收籽骨的钙化与下颌尖牙根尖闭合前牙根矿化的完成密切相关。在与这一特定骨骼发育阶段相关的牙齿成熟状态方面，未发现明显的性别差异。所研究的其余牙齿之间的相关性较低，钙化阶段分布广泛分散，且存在明显的性别差异。基于本研究的结果，下颌尖牙根尖闭合前牙根形成的完成可作为青春期生长突增开始的成熟指标，其可信度与拇指内收籽骨的钙化相似。然而，应该注意的是，这颗牙齿的成熟状态与籽骨矿化开始之间的关系可能存在种族差异。因此，在将这些发现应用于其他种族群体时应谨慎。
