Abstract

Tooth intrusion consists of the displacement of the tooth into its alveolus and is the most common trauma during early infancy. This work aims to evaluate the aspects related to tooth intrusion in primary teeth by monitoring 16 patients (22 teeth) for a period between 3 and 36 months. Of the patients who suffered from tooth intrusion, 56.25% were male and 91% of the intruding teeth were upper central incisors. In all cases the treatment indicated was to await spontaneous re-eruption: total re-eruption occurred in 42.5% of cases, partial re-eruption in 47% of cases and in 10.5% there was no re-eruption. Twenty-three percentage of the teeth suffered necrosis, 33% suffered internal or external root resorption and none suffered root canal obliteration. Fifty-seven percentage indicated healthy pulps independent of degree of re-eruption.
