The aim of this retrospective cohort study was to evaluate re\u2010eruption rates and the occurrence of sequelae in intruded primary teeth according to the degree of intrusion.<\/jats:p><\/jats:sec><jats:sec><jats:title>Material and methods<\/jats:title><jats:p>A total of 238 teeth from 168 patients diagnosed with and treated for intrusion over a 16\u2010year period at a specialized trauma center in South Brazil were included in this study. Patient details, including demographic characteristics, tooth affected, presence of sequelae of trauma during the follow up (pulp necrosis and infection, crown discoloration and abnormal mobility), and any effects on the permanent successors, were collected from their records. Photographs were analyzed to determine the degree of intrusion (Grade I, II, or III) and spontaneous re\u2010eruption during follow up. Re\u2010eruption and occurrence of sequelae according to the degree of intrusion were evaluated using the chi\u2010squared test. The level of significance was set at 5%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Most teeth were maxillary central incisors (87.8%) with Grade I intrusion (32.8%). In the first 30\u00a0days, 13.1% had signs of re\u2010eruption. After 3\u20136\u00a0months, the frequency of re\u2010eruption increased to 58.7%. Of the teeth evaluated 6\u00a0months or more after intrusion, 68% had re\u2010erupted. Total intrusion (Grade III) was associated with pulp necrosis and infection (<jats:italic>p<\/jats:italic>\u00a0=\u00a0.002), but the degree of intrusion was not associated with the presence of crown discoloration or abnormal mobility.
