Abstract

Tooth avusion implies total displacement of teeth out of its socket. Its frequency range from 0.5 to 16% of traumatic injuries. Replantation procedure is used for the treatment of avulsed tooth. However, its major complications are pulp necrosis, inflammatory root resorption and replacement root resorption. This paper describes 10 years and 2 months old male patient whose both maxillary central incisors were avulsed due to fall-down with slightly underdeveloped root apices. Teeth were replanted 2 hours after accident. Right central incisor's pulp tissues were extirpated and filled with $Vitapex^{(R)}$(calcium hydroxide) at 3-4 weeks after replantation, but left central incisor was filled at 8-9 weeks. Right central incisor showed little inflammatory resorption in apical portion, whereas left central incisor showed severe root resorption. During 18 months' follow-up period, left central incisor showed slightly ankylosis while right central incisor did not. Based upon the above-mentioned results, the following conclusions can be drawn: 1. Inflammatory resorption could be suppressed by endodontic treatment with calcium hydroxide. 2. When apex formation is doubted in replanted tooth due to avulsion, early endodontic treatment with calcium hydroxide seems to act positively for better prognosis.

외상으로 인해 치근 완성 여부가 불분명 한 완전 탈구된 치아를 재식한 후 18개월 여간 관찰하여 다음과 같은 결과를 얻었다. 1. 재식 초기의 염증성 치근 흡수는 수산화 칼슘을 사용한 근관치료로 억제될 수 있었다. 2. 치근 완성 여부가 불확실한 치아에서 조기 근관치료가 염증성 치근 흡수 및 유착의 방지에 더 큰 임상적 성공을 얻을 수 있었다. 따라서, 재식 당시 치근첨의 개방성 여부가 명확하지 않을 때에는 성인의 치료 지침에 따라 치료하는 것이 보다 효과적이며, 불가피 할 경우에는 환자 및 보호자의 철저한 교육에 뒤따른 정확한 내원 약속이 속발증을 최소화 할 수 있을 것으로 사료된다.
