Abstract
BACKGROUND
Dilaceration is a rare dental developmental anomaly characterized by an abrupt deviation along the longitudinal axis of the root in which an angulation forms between the root and the crown. Here, we report on dilacerated bilateral maxillary central incisors in mixed dentition.
CASE SUMMARY
A 10-year-old girl presented with a chief complaint of unerupted central incisors. An oral examination and radiography provided the basis for a diagnosis of dilaceration of the maxillary central incisors. After surgical exposure of the impacted teeth, a button with an attached chain was applied to the palatal surface of teeth 11 and 21. After 8 mo, a button was bonded to the labial surface of the crown to fix an elastic chain and move the teeth toward the maxillary arch. Finally, a fixed appliance was applied to tooth alignment to Class 1 malocclusion using a 0.019 × 0.025-inch nickel-titanium wire. After 3 years of follow-up, the clinical findings and radiographic assessment showed that the roots had developed with vital dental pulp and healthy periodontium, were acceptable aesthetically, and showed no resorption.
CONCLUSION
The rare occurrences of dilacerated bilateral maxillary central incisors can be successfully treated through surgical exposure and orthodontics.
Core Tip: Here, we report on a rare case of maxillary bilateral central incisors with severe root dilaceration in mixed dentition that we treated by surgical exposure followed by orthodontic treatment. The dilacerated teeth were successfully moved into the proper position with an aesthetically acceptable outcome at the three-year follow-up assessment. We also discuss the timing of and prognosis for treating dilacerated teeth.
