Time is a critical factor in successful replantation. The avulsed tooth is simply washed and replaced immediately. Where contamination with soil occurs anti-tetanus prophylaxis is given and some form of splinting is necessary for 3-4 weeks. Endodontic therapy is performed prior to replacement if there is a delay of more than two hours and where apex formation is complete it should be commenced within 10 days. Calcium hydroxide is useful as a root canal dressing and in controlling resorption. The value of immediate replacement and treatment should be publicised.
时间是再植成功的关键因素。对于脱位牙，只需简单冲洗后立即复位。若发生土壤污染，需进行破伤风预防，并且需要某种形式的夹板固定3 - 4周。如果延迟超过两小时，则在复位前进行牙髓治疗；若根尖形成已完成，应在10天内开始治疗。氢氧化钙作为根管敷料和控制吸收很有用。应宣传立即复位和治疗的价值。
