In an avulsed tooth with an open apex, a recommended procedure is to coat the root surface with topical doxycycline before reimplantation. Doxycycline, a derivative of the tetracycline family, has an antibacterial effect and anti-inflammatory qualities, and is effective in reducing inflammatory and replacement resorption following dental trauma. Treating the root surface of an avulsed closed apex tooth is a rational and recommended procedure. A case is presented in which an avulsed closed apex tooth, conditioned with topical doxycycline, was reimplanted in the socket. At follow-up, 16 months later, no clinical signs and symptoms were present and radiographic evaluation showed only superficial root surface resorption and an intact PDL.
对于根尖孔开放的脱位牙，推荐的操作是在再植前用局部多西环素覆盖牙根表面。多西环素是四环素家族的衍生物，具有抗菌作用和抗炎特性，可有效减少牙外伤后的炎症性吸收和替代性吸收。处理根尖孔封闭的脱位牙的牙根表面是一种合理且推荐的操作。本文报告了1例用局部多西环素处理后的根尖孔封闭脱位牙再植于牙槽窝内的病例。16个月后的随访显示，无临床症状和体征，影像学评估仅显示牙根表面有浅层吸收，牙周膜完整。
