Abstract
This study was designed to assess the correlation between Nutritional status and SES as factors affecting the number of permanent teeth emerged, also to assess gender differences in permanent teeth emergence, as well as to assess race differences in number of permanent teeth emerged between Egyptian children and Sudanese Nubian children. A total of 2000 children aged from 5 to 13 years, were enrolled in this study,1000 (477 males and 523 females) children from Cairo Governorate, Egypt; and 1000 Sudanese Nubian children (494 males and 506 females). For each child, a comprehensive dental examination carried out by the examiner using, artificial light, a wooden spatula to retract soft tissues, starting from the lower right quadrant then, lower left quadrant then, upper left quadrant and upper right quadrant of the jaw.The status of emergence of the permanent tooth was recorded in an examination chart specially designed for this study. Any part of the tooth emerging or erupting in the oral cavity was considered as an eruption of tooth. Any extracted permanent teeth were recorded as erupted. Since no radio-graphical examination was made, any congenital missing tooth was recorded as non-emerged
