Furthermore, treatment outcome is often unpredictable due to the presence of numerous injury-related variables affecting the treatment option and prognosis. The current report presents the case of a 14-year-old boy with a 9.0 mm intruded permanent right maxillary central incisor with a closed apex which was treated by orthodontic repositioning and root canal treatment with a favorable prognosis.
