To assess dental age in children with a complete unilateral cleft lip and palate and to compare this with a noncleft control group.
Two-group, mixed-longitudinal cohort study.
Cleft group from an academic center for cleft lip and palate treatment. Noncleft control group from the same population.
Participants included 70 Caucasian children with a full complement of teeth and a complete unilateral cleft lip and palate (45 boys and 25 girls) from the Cleft Palate Craniofacial Center at the Radboud University Nijmegen Medical Center, Nijmegen, the Netherlands. The control group (90 boys and 91 girls) was taken from the Nijmegen Growth Study.
Dental age was assessed on orthopantomograms. In the unilateral cleft lip and palate group, linear interpolation in individual age curves was applied to obtain the dental age at 5, 9.5, and 14 years of age. For these ages, a comparison was made with the noncleft control group.
Boys and girls with a unilateral cleft lip and palate showed a significant delay in dental age, as compared with their noncleft peers at all three ages. This delay was more pronounced in boys than in girls. The gender effect was significant at chronological ages 5 and 14 years.
Children with a complete unilateral cleft lip and palate have a delay in dental age, compared with noncleft children.
评估完全性单侧唇腭裂患儿的牙龄，并与非腭裂对照组进行比较。
两组混合纵向队列研究。
来自一家唇腭裂治疗学术中心的腭裂组。来自同一人群的非腭裂对照组。
参与者包括来自荷兰奈梅亨拉德堡德大学医学中心腭裂颅面中心的70名白种儿童，他们牙齿齐全且患有完全性单侧唇腭裂（45名男孩和25名女孩）。对照组（90名男孩和91名女孩）来自奈梅亨生长研究。
在曲面断层片上评估牙龄。在单侧唇腭裂组中，采用个体年龄曲线的线性插值法来获取5岁、9.5岁和14岁时的牙龄。针对这些年龄，与非腭裂对照组进行比较。
与非腭裂同龄人相比，单侧唇腭裂的男孩和女孩在所有三个年龄的牙龄均显著延迟。这种延迟在男孩中比在女孩中更明显。在实际年龄5岁和14岁时，性别效应显著。
与非腭裂儿童相比，完全性单侧唇腭裂患儿的牙龄延迟。
