Dental maturity assessment is crucial for orthodontic treatment planning, especially in children with cleft lip and palate (CLP), as they often exhibit delayed dental development. The correlation between dental, skeletal, and chronological age remains uncertain, particularly in complex cases like CLP.
The aim of this study was to compare the development of permanent teeth in children with cleft lip and palate (CLP) to that of normal children without CLP of the same age and gender.
The study evaluated panoramic radiographs from 240 children with CLP (112 males, 128 females, ages 5-15, mean age 9.28 years) and 350 healthy controls (187 males, 163 females). Dental age was assessed using the Demirjian method, which evaluates the mineralization stages of seven mandibular teeth on the left side. Radiographs were coded to minimize bias, and dental maturity scores were converted to dental age using gender-specific conversion tables.
No significant difference in dental age was observed between children with and without CLP across most age groups. However, at age 9, male CLP patients exhibited significantly delayed dental maturity compared to females. High correlations were noted between dental and chronological ages in both groups.
Dental maturity in Saudi children with CLP is generally comparable to their non-CLP counterparts, except for delayed dental development in males at age 9.
牙齿成熟度评估对于正畸治疗计划至关重要，尤其是对于唇腭裂（CLP）儿童，因为他们常常表现出牙齿发育延迟。牙齿、骨骼和实际年龄之间的相关性仍不确定，特别是在唇腭裂等复杂病例中。
本研究的目的是比较唇腭裂（CLP）儿童与年龄和性别相同的非唇腭裂正常儿童恒牙的发育情况。
该研究评估了240例唇腭裂儿童（112例男性，128例女性，年龄5 - 15岁，平均年龄9.28岁）和350例健康对照者（187例男性，163例女性）的全景X线片。使用Demirjian方法评估牙齿年龄，该方法评估左侧七颗下颌牙齿的矿化阶段。对X线片进行编码以尽量减少偏差，并使用特定性别的转换表将牙齿成熟度评分转换为牙齿年龄。
在大多数年龄组中，唇腭裂儿童和非唇腭裂儿童的牙齿年龄没有显著差异。然而，在9岁时，男性唇腭裂患者的牙齿成熟度明显低于女性。两组中牙齿年龄和实际年龄之间均存在高度相关性。
沙特唇腭裂儿童的牙齿成熟度总体上与其非唇腭裂同龄人相当，但9岁男性儿童牙齿发育延迟。
