摘要

牙齒外傷多發生在青少年或孩童身上，受傷的牙齒常為上顎門牙。在這些牙齒外傷中，壓入性外傷和牙齒脫落是較為嚴重的。這個病例是一位十三歲男童在學校樓梯跌倒，造成左上正中門牙壓入性傷害。經過固定復位後，男童搖動牙齒導致樹脂脫落，鋼線鬆脫，因此再度固定復位並提醒男童注意事項。但是男童當天第三度出現在牙科門診並把已復位的牙齒拿在手上，因為男童將原本復位的牙齒搖至脫落。於是對牙齒在口外進行根管治療，並再度固定復位。牙齒壓入性外傷和脫落長期預後通常相當不佳，雖然此病例目前狀況良好，但還需要對此病例進行追蹤。

Dental trauma often occurs in adolescent, especially at upper incisors. Tooth intrusion or avulsion is much more serious among these dental trauma. In this case, a 13-year-old male fell down from stairs at school, causing upper left central incisor intrusion. After fixation with wire, the patient shook the tooth, so the resin and wire was dislodged. The patient came to our hospital again. We warned the patient not to touch the tooth after FIxation with wire. However, the patient shook the tooth o, he came back hospital the third time on the same day with the repositioned intrusive tooth in his hand. The avulsion tooth was root canal treated extraorally first, then plant the tooth into the socket with fixation. This kind of dental trauma injury's prognosis is very bed in longterm follow. Though the tooth heals well now, it still need to follow for a long time.
