To provide a detailed description of crown size dimensions in the permanent dentition of Jordanian cleft lip and palate patients and to compare the findings with those of other populations.
The mesiodistal crown diameters of the permanent teeth of 47 patients with unilateral cleft lip and palate (UCLP), 25 patients with bilateral cleft lip and palate (BCLP), and 74 controls were measured.
The cleft group (UCLP and BCLP patients) generally demonstrated a smaller tooth size for both the maxillary and mandibular arches than did the control group. A sexual dimorphism pattern with males having larger teeth than females was observed for controls and UCLP patients. More males with BCLP had smaller teeth than did females. In the maxilla, the UCLP cleft-side teeth showed the largest percentage (4%) of sexual dimorphism, whereas the BCLP teeth achieved the highest percentage (3.4%) in the mandible. The UCLP cleft-side maxillary lateral incisors (13.2%) and BCLP mandibular canines (6%) displayed greater sexual dimorphism in crown size than did any other tooth class.
Tooth size reduction occurred across all permanent tooth types and among early and late-forming teeth in cleft patients compared with the controls. This reduction was more pronounced in the maxillary incisor field. Males with UCLP and control males had larger teeth than did females, whereas a reversal of the normal dimorphism pattern was observed in patients with BCLP.
详细描述约旦唇腭裂患者恒牙列的牙冠尺寸，并将结果与其他人群进行比较。
测量了47名单侧唇腭裂（UCLP）患者、25名双侧唇腭裂（BCLP）患者和74名对照者恒牙的近远中牙冠直径。
腭裂组（UCLP和BCLP患者）的上颌和下颌牙弓牙齿尺寸通常比对照组小。在对照组和UCLP患者中观察到性别二态性模式，男性牙齿比女性大。更多BCLP男性的牙齿比女性小。在上颌，UCLP腭裂侧牙齿的性别二态性百分比最高（4%），而BCLP牙齿在下颌达到最高百分比（3.4%）。UCLP腭裂侧上颌侧切牙（13.2%）和BCLP下颌尖牙（6%）在牙冠尺寸上的性别二态性比其他任何牙类都更明显。
与对照组相比，腭裂患者所有恒牙类型以及早形成和晚形成牙齿的牙尺寸均减小。这种减小在上颌切牙区域更为明显。UCLP男性和对照男性的牙齿比女性大，而BCLP患者中观察到正常二态性模式的逆转。
