Management of intrusive luxation injuries of the primary incisor: A case report

Introduction: Intrusive luxation is commonly seen in primary dentition as young children have wide medullar spaces in their alveolar bone. The management of intruded primary incisors recommended by the American Academy of Pediatric Dentistry is to wait for spontaneous re-eruption or extract the tooth, depending on the degree and the direction of intrusion as well as the presence of alveolar bone fracture. Comprehensive examination is essential for determining the most appropriate approach. Here we report our experience with a case of intrusive luxation in the left maxillary lateral incisor of a 6-year-old patient. Case Report: Intrusive luxation of left maxillary lateral primary incisor (tooth #62) was diagnosed, the tooth was in contact with the underlying permanent tooth and the treatment of extraction of the intruded tooth was performed. Recall examination was regularly conducted to monitor the eruption of the permanent successor. Direct trauma caused by simulation of deciduous teeth can impact the permanent successor. By extracting tooth #62, direct trauma to permanent successor tooth #22 was minimized so the development can be continued normally. Recall examination post extraction on week 1 and 4 revealed no unusual symptoms such as abscess, fever, fistula or soft tissue swelling. Conclusion: Intrusive injuries need a careful examination owing to their close anatomical association with the developing permanent successors. In the case of intrusive luxation of tooth #62, due to the root impacting the underlying permanent tooth, extraction was selected as the ideal treatment approach.
