Australian longitudinal study of time and order of eruption of primary teeth.
Timing and sequence of eruption of primary teeth were studied longitudinally in 164 healthy Australian children. Eruption of primary teeth typically began between 7 and 8 months and was completed by 28 months. Tooth eruption was not significantly related to growth rate or to psychomotor maturity. Comparison of the eruption ages in this study with those from longitudinal studies in other countries suggests that no real changes in these have occurred over 40 yr despite increased affluence in industrialised countries over that period.
