To evaluate the presence of enamel alterations in deciduous maxillary central incisors of infants with unilateral cleft lip and alveolar ridge, with or without cleft palate, and to compare the occurrence and location of these alterations between the central incisor adjacent to the cleft and the contralateral incisor.
Intraoral clinical examination was performed after tooth cleaning and drying by a single examiner with the aid of a dental mirror, dental probe, and artificial light, with the child positioned on a dental chair. The defects were recorded in a standardized manner according to the criteria of the Modified Developmental Defects of Enamel Index.

One hundred one infants were evaluated. All were white, of both genders, aged 12 to 36 months and had at least two thirds of the crowns of maxillary incisors erupted.
Demarcated opacity was the most common defect at both cleft and noncleft sides, followed by diffuse opacity. The occurrence of hypoplasia at the cleft side was 11.8%. Most defects affected less than one third of the crown.
The occurrence of enamel defects in deciduous maxillary central incisors of patients with unilateral cleft lip was 42.6%, mainly affecting the cleft side as to both number and severity.
评估单侧唇腭裂及伴或不伴腭裂的婴儿上颌乳中切牙釉质改变的情况，并比较裂隙旁中切牙与对侧中切牙这些改变的发生率及部位。
由一名检查者在儿童坐在牙科椅上，借助口镜、探针及人工照明，对牙齿进行清洁和干燥后进行口腔临床检查。根据改良釉质发育缺陷指数标准以标准化方式记录缺陷情况。
巴西圣保罗鲍鲁颅面畸形康复医院。
对101名婴儿进行了评估。所有婴儿均为白人，男女不限，年龄在12至36个月之间，上颌中切牙至少有三分之二的牙冠已萌出。
界限清晰的釉质混浊是裂隙侧和非裂隙侧最常见的缺陷，其次是弥漫性混浊。裂隙侧发育不全的发生率为11.8%。大多数缺陷累及不到三分之一的牙冠。
单侧唇裂患者上颌乳中切牙釉质缺陷的发生率为42.6%，在数量和严重程度上主要影响裂隙侧。
