Root resorption after replantation is related to the use of various drugs stored on the media and root surface prior to implantation. The aim of this study was to examine the effect of topical application of stannous fluoride, tetracycline (doxycycline hyclate), or both, on the mandibular incisors of a withdrawn dog. The authors selected five dogs of 15 months of age to be tested. Four lower incisors were pulled from each dog under anesthesia without root canal treatment and immediately rinsed with saline.
