The Association between the Facial and Dental Arch Forms

Background This study aimed to find out the association between the facial forms and the dental arch forms in a sample of Iraqi adults with normal dental, sagittal and transverse jaws relations. Materials and Methods Eighty dental students participated in this study. Standardized frontal photographs for the face were taken to determine the facial taper angle. Maxillary and mandibular dental casts were obtained to classify the dental arch forms. The association between the facial forms and dental arch forms was determined by Pearson's Chi square test. Results and Conclusions There was no significant association between the facial and dental arch forms except in females between the mandibular dental arch and face.
