In addition to the successful replantation of avulsed permanent teeth, the replantation of primary anterior teeth may also be indicated. The decision is based on age and stage of tooth development, development of dentition, storage of the avulsed tooth and the way it is transported to the treatment site, the appropriate in vitro treatment of the tooth before reinsertion, and the willingness of the child to cooperate. A method involving retrograde filling of the primary tooth root with calcium hydroxide after resecting the root apex has proved successful. Other commercially available root filling materials and pins are not indicated. Calcium hydroxide allows the tooth to heal in place without reaction and prevents the development of apical periodontitis. As regards any surgical intervention, the attending dentist in this case has to weigh the benefits against the risks.
除了成功再植恒牙脱位外，也可能需要再植乳前牙。这一决定基于牙齿发育的年龄和阶段、牙列发育情况、脱位牙齿的保存及运输至治疗部位的方式、再植入前牙齿适当的体外处理以及儿童的合作意愿。一种在切除根尖后用氢氧化钙逆行充填乳牙根的方法已被证明是成功的。不建议使用其他市售的根管充填材料和桩钉。氢氧化钙可使牙齿原位愈合而无反应，并防止根尖周炎的发生。至于任何外科干预，在这种情况下主治牙医必须权衡利弊。
