The aim of this study was to assess the magnitude of occlusal changes in individuals with unilateral cleft lip and palate (CLP). The study was conducted on study cast models of 25 subjects, 14 men and 11 women aged from 7 to 20 years, without previous orthodontic treatment and with surgical repair carried out at São Marcos Hospital, Teresina, Piauí State, Brazil.
The cast models were assessed by three orthodontists based on the occlusal scores established by Atack et al., whose scores range from 1 to 5, according to the magnitude of transverse and sagittal changes.
Intra and inter-observer reproducibility of occlusal scores was satisfactory and statistically significant according to the Spearman correlation test with significance level set at 5%. With regard to the distribution of occlusal scores, 30.67% of the subjects achieved scores 1 and 2, 22% score 3 and 47.53% achieved scores 4 and 5.
Four was the score most frequently assigned by the observers, disclosing a high degree of transverse and sagittal disorders in the occlusion of patients.
本研究旨在评估单侧唇腭裂（CLP）患者咬合变化的程度。该研究在25名受试者的研究模型上进行，其中14名男性和11名女性，年龄在7至20岁之间，未曾接受过正畸治疗，且在巴西皮奥伊州特雷西纳市圣马科斯医院接受过手术修复。
由三名正畸医生根据阿塔克等人制定的咬合评分对模型进行评估，该评分根据横向和矢状面变化的程度从1到5分。
根据Spearman相关性检验，观察者内和观察者间咬合评分的再现性令人满意且具有统计学意义，显著性水平设定为5%。关于咬合评分的分布，30.67%的受试者得分为1分和2分，22%得3分，47.53%得4分和5分。
观察者最常给出的分数是4分，这表明患者咬合中存在高度的横向和矢状面紊乱。
