Аннотация
The existing eruption schedules for permanent and deciduous dentition are based on studies in industrialized countries. This study determined the dates of emergence of deciduous teeth in a cross-sectional sample of 1132 Egyptian infants aged 4-36 months selected from different governorates of Egypt. The dates of emergence of individual teeth were calculated using Probit analysis. The mandibular left and right incisors were the earliest teeth to emerge at a mean of 8.0 months in boys and 7.9 months in girls. The sequence of eruption followed a typical pattern. The average time from emergence of the first tooth to the last tooth was 17.8 months in the mandible and 15.8 months in the maxilla for boys and 22.1 and 20.1 months respectively for girls. Four active phases of emergence were identified and compared with data from other countries.
