Injured teeth are commonly encountered in daily clinical work. This report a case of 7-year 10-month old boy with traumatically shedded upper bilateral central incisors with immature roots. These teeth were replanted. We observed the progress after treatment for 9 con-secuitive years. The results are as follows: 1. Incisors' roots were observed to grow in spite of the absence of Hertwig's epithelial sheath and death of pulp tissue. 2. The apexification of roots occurred even traumatically injured replanted tooth with immature roots. 3. The teeth were in anklylosis and absorption. This is thought to be caused by twice traumatic injuies and tongue habit. From above results, when a traumatically shedding tooth with immature root was replanted. Then, it should be provided apexification using calcium hydroxide, and the bad oral habit should be also corrected.
