Morphologic and biochemical changes of the masseter muscles induced by occlusal wear: studies in a rat model.

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...
