Aims This study aimed to determine the kinds of sequelae resulting from intrusive luxation and subluxative injuries in primary anterior teeth as well as the timing of such sequelae. Materials and methods In this longitudinal retrospective study, data were collected from dental records and radiographs of patients with traumatic dental injury ( TDI ) treated at the Centre for the Study and Treatment of Dental Trauma in Primary Dentition (Pelotas, RS , Brazil). Fifty‐two children, with seventy intruded teeth, and 76 children, with 99 subluxated teeth, met the inclusion criteria. Sequelae, such as crown discoloration, fistula, pulp canal obliteration ( PCO ), inflammatory root resorption ( IRR ), and internal root resorption, were investigated. The data on the sequelae were distributed into eight follow‐up periods: 0–30 days, 31–90 days, 91–180 days, 181–365 days, 1–2 years, 2–3 years, 3–4 years, and >4 years. Results The sample comprised 99 subluxation cases and 70 intruded teeth. Crown discoloration was the most prevalent sequelae. Among the subluxated teeth, <50% of IRR , fistula, crown discoloration, and PCO occurred within 180 days after TDI ; however, the sequelae were also diagnosed after longer periods. Majority of sequelae of intrusion were diagnosed within the 181–365 days and 1–2 years periods but were also observed after more than 4 years of follow up. Conclusions For both intrusion and subluxation, trauma sequelae were diagnosed even after the 3–4 years of follow‐up.
