title: Timing and sequence of eruption of permanent teeth in a longitudinal sample of children from Oregon.
abstract: A longitudinal sample of children was examined for timing and sequence of eruption of permanent teeth. Separate consideration was given to 124 boys and 163 girls from the Child Study Clinic longitudinal growth study. Girls show more variability in age at eruption than boys, and eruption is generally earlier in girls. The degree of variation in sequences of eruption of the first seven permanent teeth is distinct. The most common sequence in girls' maxillas occurred in only 11.4% of subjects; in boys, the most common sequence appeared in 13.4% of subjects. Predictability efficiency of eruption of the first three permanent teeth is not higher than 0.74.
