Cleft lip and palate (CLP) is the most common congenital malformation of the head and neck. Children with CLP often exhibit dental anomalies.
To evaluate the dental age (DA) of unilateral CLP in Tunisian children.
This was a cross-sectional study carried out in the department of pediatric dentistry at the University Hospital La Rabta, Tunis. Patients aged between 5 and 14 years, with no other congenital anomalies or syndromes in the craniofacial region other than CLP, were included. The patients' chronological ages were first calculated in years and months. DA was assessed in panoramic radiographs using Demirjian's method. The score of each stage is allocated, and the sum of the scores provides an evaluation of the subject's dental maturity.
Fifty-three patients were included in the present study. No difference was observed between the two groups regarding the dental age. A strong and positive correlation between the DA and the chronological age in the two groups was observed (r=0.826). Estimated regression showed that chronological age alone explained 57,4% (r2=0.574) of the dental age variation in the study group and 64.5% (r2=0.645) in the control group.
For dental management, CLP children should have the same approach in orthodontics and pediatric dentistry as individuals without clefts, with a focus on the individualization of diagnosis and treatment planning.
唇腭裂（CLP）是头颈部最常见的先天性畸形。CLP 患儿常伴有牙齿畸形。
评估突尼斯单侧 CLP 儿童的牙龄（DA）。
这是一项在突尼斯拉巴特大学医院儿科牙科系进行的横断面研究。纳入年龄在 5 至 14 岁之间，除 CLP 外，头面部无其他先天性异常或综合征的患者。患者的实际年龄首先以年和月计算。DA 通过 Demirjian 法在全景片上进行评估。为每个阶段分配评分，总评分提供对受试者牙齿成熟度的评估。
本研究共纳入 53 例患者。两组之间的牙龄无差异。两组中 DA 与实际年龄之间存在强烈的正相关（r=0.826）。估计回归显示，在研究组中，实际年龄单独解释了 57.4%（r2=0.574）的牙龄变化，在对照组中解释了 64.5%（r2=0.645）。
对于牙科管理，CLP 患儿在正畸和儿科牙科方面应与无裂隙的个体采用相同的方法，重点是个体化诊断和治疗计划。
