Study of occlusion in a group of Egyptian children suffering from thalassemia

This work was carried out to study the occlusion in a group of Egyptian thalassemic children. The sample consisted of seventy Egyptian male children ranging in age from nine to forteen years. The sample was divided into two groups. The first group consisted of forty children suffering from thalassemia major, while the other group consisted of thirty normal children. For every subject of the study full study models analysis were done. It was found that all maxillary cast measurements as well as overjet and overbite measurements of thalassemic patients were significantly higher than those of normal children. Where as there was no significant difference in the palatal vault depth as well as in all the mandibular cast measurements between the two groups

Dento-skeletal pattern in a group of thalassemic Egyptian children

This work was done in order to study the dentoskeletal pattern of a group of Egyptian children suffering from thalassemia. The sample studied consisted of seventy Egyptian children ranging in age between nine and forteen years. The sample was divided into two groups; the first group consisted of forty children suffering from thalassemia major and the other group consisted of thirty normal children. For every subject in the study lateral cephalometric analysis was done. It was found that in thalassemic patients there was significant lengthening of the anterior cranial base, downward and backward rotation of the mandible with increase in the lower face height, while there was no significant abnormality in the antero-posterior position of the maxillary. Upper incisors were retroclined in thalassemic patients, whereas there were no significant difference in the remaining dental cephalometric measurements recorded when compared to normal children

Effect of breast and bottle feeding on the maxillary intercanine width in a group of Egyptian children

360 nursery child aged 3-4 years - 175 males [70 breast fed and 105bottle fed] and 185 females [66 breast fed and 199 bottle fed]. Maxillary intercanine width was measured and the data was analyized according to sex and feeding pattern. The result indicated that there is no significant difference in relation sex. But there is a statistical significant difference the maxillary intercanine arch width in relation to feeding pattern
