Summary
Based on data obtained
from a prospective epidemiological study in a random sample of 4468 Flemish
children, accurate emergence ages for permanent teeth could be established. When
data on permanent tooth emergence in different populations are compared,
differences are most pronounced for premolars. Several authors hypothesised that
this difference could be explained by a difference in caries experience in the
primary molars. The purpose of this study was to quantify the effect of caries
experience in a primary molar on the timing of emergence of its successor. The
results indicate that the emergence of the premolars was accelerated by 2 to 8
months when its predecessor had been decayed and or filled but had not been
extracted. Premature loss of maxillary primary molars resulted in a significant
acceleration of the emergence of the premolars; this was not observed in the
mandible. In conclusion, when considering permanent tooth emergence ages, caries
experience in the primary dentition should be taken into account.
