Objective. To evaluate characteristics of smile related to visibility in individuals with cleft lip, alveolus, and palate. Design. Cross-sectional. Setting. HRAC/USP, Brazil. Patients. Individuals with repaired complete unilateral cleft lip and palate (n = 45), aged 15-30 years. Interventions. Frontal facial photographs were obtained in natural and forced smiles (n = 135). Six specialists in periodontics evaluated the photographs as to the smile line, thickness, and curve of the upper lip. Main Outcome Measures. The cleft area was compared with the contralateral region. Results were expressed as percentages and means. The findings were compared between groups of periodontists. Results. Statistically significant relationship was observed in the smile line between examiners and between natural and forced smiles, regardless of the association with the cleft side. The lip was thicker at rest and thinner in the forced smile, as also evaluated by the group not experienced with cleft care. The curve of the upper lip in natural and forced smiles was considered as close to straight by both groups, regardless of the cleft. Conclusion. The smile in individuals with clefts was regarded as average for both cleft and noncleft sides. The thickness was characterized as average to thin, being thinner in forced smile and when analyzed by the group not experienced with cleft care. In the average, the curve of the upper lip was considered as straight. The present study elucidates some characteristics related to the smile in individuals with repaired unilateral cleft lip, alveolus, and palate.
目的。评估唇腭裂患者微笑时与可见度相关的特征。设计。横断面研究。地点。巴西HRAC/USP。患者。15至30岁的单侧完全性唇腭裂修复患者（n = 45）。干预措施。获取自然微笑和强制微笑时的正面面部照片（n = 135）。六位牙周病专家对照片的微笑线、上唇厚度和曲线进行评估。主要观察指标。将裂隙区域与对侧区域进行比较。结果以百分比和均值表示。在牙周病专家组之间比较研究结果。结果。无论与裂隙侧的关联如何，在检查者之间以及自然微笑和强制微笑之间，微笑线存在统计学上的显著关系。未经裂隙护理经验的组评估发现，唇部在静止时较厚，在强制微笑时较薄。无论是否有裂隙，两组均认为自然微笑和强制微笑时上唇曲线接近直线。结论。裂隙患者的微笑在裂隙侧和非裂隙侧均被视为中等。厚度特征为中等至薄，在强制微笑时以及由未经裂隙护理经验的组分析时更薄。总体而言，上唇曲线被认为是直的。本研究阐明了单侧唇腭裂修复患者微笑的一些相关特征。
