Evaluation of 3-dimensional tooth crown size in cleft lip and palate patients
Introduction: The aims of this study were to evaluate 3-dimensional (3D) tooth crown sizes in patients with cleft lip and palate (CLP) and to compare them with those of a Class I control group. Methods: Orthodontic dental casts were used of 72 subjects with CLP (20 bilateral [BCLP], 34 unilateral le...

Zusammenfassung: | Introduction: The aims of this study were to evaluate 3-dimensional (3D) tooth crown sizes in patients with cleft lip and palate (CLP) and to compare them with those of a Class I control group. Methods: Orthodontic dental casts were used of 72 subjects with CLP (20 bilateral [BCLP], 34 unilateral left [ULCLP], 18 unilateral right [URCLP]) and 53 adolescents in the permanent dentition stage with Class I occlusion. Mesiodistal (MD), labiolingual (LL), and occlusogingival (OG) measurements were recorded by the same examiner using a digital caliper. Statistical analyses were conducted, including repeatability, analysis of variance (ANOVA), and the Duncan tests. Results: Maxillary and mandibular premolar MD dimensions were larger in the CLP groups than in the control group. The smallest MD dimensions were those of the maxillary right lateral incisors in the BCLP group ( P |
