Abstract
In the field of pediatric dentistry, we have encountered many children with trauma of deciduous teeth in clinical practice.In particular, the prognosis of tooth dislocation depends on children's cooperation and the presence or absence of anchorage for the injured teeth. Furthermore, it is necessary to help children's parents understand the influence of an injured deciduous tooth on a succeeding permanent tooth, and continue periodic management over a long period until the completion of permanent-tooth growth.In this case, we report an 11-month-old infant with traumatic dislocation of the bilateral lower primary central incisors in whom labial-side gingival resection at the site of the lower primary lateral incisors, which were in the process of growing, and anchorage-based reduction were performed to preserve the bilateral lower primary central incisors. To date, the course has been favorable.
