Detailed notes

- The aim of this investigation was to evaluate the dental and craniofacial characteristics of subjects with amelogenesis imperfecta (AI) using lateral cephalometric radiography. The sample consisted of the lateral cephalometric radiographs of 20 AI patients, irrespective of orthodontic malocclusion, and 18 healthy control subjects. Commonly used cephalometric measurements (8 linear, 6 angular) were compared between groups. Differences were tested with analysis of variance and Duncan's test. Intra-class correlation coefficients were used to examine intra-observer reliability. The AI group displayed significant differences from the control group, indicating a tendency towards a skeletal open-bite malocclusion (p < 0.01). Despite the random selection of AI cases, the mean intermaxillary relationship of the AI group fell within the Class I malocclusion type. The AI group showed increased anterior facial height (p < 0.01) and decreased posterior facial height (p < 0.01) in comparison with the control group. No significant difference was found in maxillary or mandibular effective lengths. Open-bite malocclusion was found in 35% of patients with AI. The mean vertical dimensions were increased in the AI group. These characteristics are considered to be skeletal in origin, although the etiological relationship between AI and skeletal disharmony remains unknown.
