Traumatic tooth avulsion requires an urgent intervention to replant the tooth. Prolonged post-injury dry extra-oral conditions worsen the prognosis and increase the risk of root resorption. Fluoride has the potential to delay replacement resorption. Calcium silicate cements (CSC) are used to seal the root canal system and to stimulate periapical regeneration in immature open apex teeth (apexification). This report suggests the application of a novel fast-setting CSC with fluoride for apexification in an attempt to hinder root resorption.
A delayed replantation of an avulsed open apex permanent central incisor after 75 h of storage in a dry condition in a 6-year-old girl. Standard treatment guidelines for avulsed immature permanent teeth were followed. After tooth replantation a novel fast-setting, CSC containing fluoride was used for apexification.
FOLLOW-UP: The radiographic and clinical evaluations over a period of 3 years demonstrated periodontal bone healing without root resorption, mobility, and ankylosis and an acceptable periapical tissue tolerance to the novel CSC. However, a longer follow-up period is needed.
Delayed replantation of the avulsed open apex permanent incisor after 75 h of storage under dry conditions and apexification with a novel fast-setting CSC showed a successful outcome after 3 years. Novel CSC with fluoride demonstrated an acceptable biocompatibility and tissue tolerance.
外伤性牙齿脱臼需要紧急干预以重新植入牙齿。伤后长时间的口外干燥状况会使预后恶化，并增加牙根吸收的风险。氟化物有可能延缓替代性吸收。硅酸钙水门汀（CSC）用于封闭根管系统，并刺激未成熟开放根尖牙齿的根尖周再生（根尖形成术）。本报告建议应用一种新型含氟快速凝固CSC进行根尖形成术，以试图阻碍牙根吸收。
一名6岁女孩的一颗脱臼的开放根尖恒中切牙在干燥条件下保存75小时后延迟再植。遵循了脱臼未成熟恒牙的标准治疗指南。牙齿再植后，使用一种新型含氟快速凝固CSC进行根尖形成术。
3年期间的影像学和临床评估显示牙周骨愈合，无牙根吸收、松动和粘连，并且根尖周组织对新型CSC具有可接受的耐受性。然而，需要更长的随访期。
在干燥条件下保存75小时后的脱臼开放根尖恒中切牙延迟再植，并使用新型含氟快速凝固CSC进行根尖形成术，3年后显示出成功的结果。新型含氟CSC表现出可接受的生物相容性和组织耐受性。
