— The present study was made to assess the effect of applying SnF 2 , tetracycline, or both, to root surfaces of extracted teeth prior to replantation. In five young adult beagles, a total of 18 mandibular incisors were extracted, bench dried for 45 min, and reimplanted in their respective sockets either after no further treatment or following treatment with 1 % doxycycline HC1 for 5 min, 1% SnF 2 for 5 min, or 1% SnF 2 followed by 1% doxycycline HG1. After 4 wk of healing, the relative frequency of root resorption (surface resorption, inflammatory resorption and replacement resorption) was approximately 27% of the root surface in bench‐dried as well as in doxycycline‐treated specimens. By contrast, SnF 2 ‐treated and SnF 2 + doxycycline‐treated teeth showed less than 1% resorption. In the latter two specimen groups an inflammatory reaction in the periodontal ligament without resorption occurred with a frequency of 38.3% and 11.1%, respectively. The results indicate that application of SnF 2 to the root surface prior to replantation effectively reduces resorptive processes during the first postoperative weeks. By subsequently treating the root surface with tetracycline, the adverse effect of SnF 2 on periodontal connective tissue repair may be reduced.
