RESUMO
AIM: Among traumatic dental injuries, intrusive dislocation is considered to be one of the most serious injuries. Despite the high success rate in complacent patients, the traditional technique of calcium hydroxide inoculation has drawbacks. The good antimicrobial and sealing properties combined with excellent biocompatibility and high success rates of the mineral trioxide aggregate (MTA) encourage its use. BACKGROUND: The objective of this study was to report a successful case of intrusive dislocation in a short time with a follow-up of eight years. CASE DESCRIPTION: A patient, seven years of age, presented intrusive dental dislocation, confirmed by radiographic examination, which revealed besides axial displacement of the central incisor towards the bone, incomplete root development. The passive repositioning was chosen as the treatment modality. After cleansing of the root canal, therapy with hydroxide paste was performed for 30 days, and then the apex was closed using an artificial barrier made with apical MTA buffer to facilitate root canal obturation. CONCLUSION: Clinical and radiographic signs at 6 months and 8 years of preservation evidence the success of the therapy. CLINICAL RELEVANCE: Teeth with incomplete root formation when traumatized may have their development process interrupted; consequently their root canals remained ample with thin and fragile walls and the open apex which represents a great challenge to the accomplishment of endodontic therapy. The process of apexification with MTA as in this case is an alternative to traditional therapy based on calcium hydroxide, conferring a faster treatment and a decrease in the odds of fracture of the tooth since from the confection of the apical barrier there is a possibility of being the same restored at an early stage.

RESUMO
Traumatic dental intrusion is a serious injury and results in significant damage to the periodontal ligament, dentin-pulp complex, and alveolar bone. This article presents a case of severe intrusion of the two upper permanent central incisors where the treatment option was the combination of the surgical and orthodontic technique. The difficulty of accessing the crowns of these teeth to bond the brackets was solved by lifting a full thickness flap. To disengage the teeth from the alveolus, a careful dislocation motion was performed. After suturing the flap, a removable orthodontic appliance was installed and an extrusive force was applied for 8 weeks. After 10 weeks, the endodontic treatment was performed and the crowns were restored. The 10-year clinical control showed normal mobility. Radiographically, minor losses of the cervical alveolar cortical bone and integrity of the periodontal ligament were observed.
RESUMO
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.
