Alexandria analysis: radiographic cephalometric standards for Egyptian adults

A radiographic cephalometric study was performed on a group of Egyptian University students. The subjects included 100 males and 100 females, between 18 and 25 years of age and with clinically acceptable occlusion and harmonious facial features. None of them had undergone orthodontic treatment. The object of this study is to establish craniofacial and soft tissue standards to be used by the clinicians on the Egyptian population. Twenty two angular measurements, thirteen linear measurements, and three ratios were established covering the most significant skeletal, dental and soft tissue parameters. The data obtained is presented in a convenient clinical table to assist orthodontists in diagnosis and treatment planning
