A study of in vivo fluoride uptake by dental tissues from fluoride-containing silver amalgams.

abstract：:Selective recruitment of periodontal ligament cells to a previously exposed root surface is believed to enhance periodontal regeneration. It has been hypothesized that competition from gingival fibroblasts may reduce the potential of periodontal regeneration. We compared the migratory responses of PDL cells and gingiv...
