Abstract: An 11-year-old child presented with an intrusive luxation of the maxillary central incisors due to trauma. Prompt treatment was provided, including repositioning, fixation, and root canal therapy. After 14 months, root resorption was observed. Through CBCT analysis, the author applied two different treatment methods for root resorption in different locations. A 2-year follow-up observation showed no new sinus formation.

Key words: tooth intrusive luxation, root resorption
