We measured the mesio-distal and bucco-lingual crown diameters of 13 males with the fra(X) or Martin-Bell syndrome. Fluctuating crown-size asymmetry was calculated and compared with values obtained in normal Caucasian children and also with a sample of 19 males with Down syndrome. A statistically significant increased asymmetry was found in the fra(X) males when compared to normal control individuals. In the maxilla, Down syndrome males showed a significantly higher tooth crown asymmetry than fra(X) males. (less than 0.02); in the mandible, no significant differences were found between the 2 groups. It is suggested that crown size asymmetry be included in the evaluation of fra(X) males.
我们测量了13名患有脆性X染色体（fra(X)）或马丁-贝尔综合征的男性的近远中径和颊舌径牙冠直径。计算了牙冠大小的波动不对称性，并与正常高加索儿童以及19名患有唐氏综合征的男性样本所获得的值进行了比较。与正常对照个体相比，发现fra(X)男性的不对称性在统计学上显著增加。在上颌骨中，唐氏综合征男性的牙冠不对称性显著高于fra(X)男性（小于0.02）；在下颌骨中，两组之间未发现显著差异。建议将牙冠大小不对称性纳入对fra(X)男性的评估中。
