The aim of this study was to determine the rime and sequence of primary teeth eruption among children residing in Tehran from birth (2000 – 2002). Materials and Methods: To achieve true statistics of time and sequence of primary teeth eruption, 542 newborn children, whose parents had lived for at least three years in Tehran, were selected randomly from five areas in Tehran. During more than two and half years follow–up,785 of them continued their co-operation.
