| Abstract | ||
| Many orthodontists evaluate dental asymmetry clinically by comparing landmarks on the occlusal surfaces of dental casts. The purpose of this study was to quantify and describe maxillary intra-arch asymmetry in 30 Iraqi children in the mixed dentition and to determine if a relationship exists between left and right side. The occlusal surfaces of casts were photographed and the measurements were carried out on photographs using a computer program. The median palatal plane (MPP) was used as a reference for transverse measurements and transverse palatal plane (TPP) was the reference for anteroposterior measurements. Asymmetry greater than 2.0 mm was present at any one landmark in 33.3 % of the sample. Transverse asymmetries exceeded anteroposterior asymmetries in magnitude and prevalence. Many children in the mixed dentition have intra-arch asymmetries that are more severe and prevalent in the transverse plane than in the anteroposterior plane. A high association (Pearson’s correlation) was present between the positions of anteroposterior and transverse maxillary intra-arch landmarks | ||
