Abstract
In 155 examinees (77 boys and 78 girls) who, apart from the premature loss of one tooth from the zone of resistance had no other disorder in the growth of the masticating region, the effect of premature extraction on the eruption of succedaneous teeth has been studied by analyzing the subjects orthopantomographic findings. With regard to the groups of teeth analyzed, it has been established that premature extractions influenced the accelerated eruption of: + C + in 30.97% of the cases, of — C — in 28.4%, + P1 + in 47.1%, — P1 — in 38.06%, + P + in 35.0% and of — P2 — in 45.0% of the cases. With regard to sex, a comparison of the eruption of homologous pairs of teeth has demonstrated that the differences in the eruption of teeth were more frequent in both jaws in boys (t = 5 P < 0.05). Concerning the jaws, the differences in the eruption were not significant in either sex (t = 1 P > 0.05) .
