In vitro growth of periodontal fibroblasts on treated cementum.
The aim of the present study was to assess the ability in vitro of phosphoric and citric acids, applied on human root cementum, to neutralize noxious plaque and calculus and to allow the growth of human gingival fibroblasts. Fibroblasts grown on cementum treated with phosphoric acid appeared typically elongated and aligned parallel to the root surface. Fibroblasts grown on cementum treated with citric acid, in both normal and periodontally diseased teeth, lost their elongated shape, acquiring polygonal borders with irregular cytoplasmic extrusions, and the cell density was significantly lower. These findings suggest that phosphoric acid cleaning of both normal and diseased root surfaces may result in an oriented, high rate of fibroblastic growth with more effective periodontal cellular proliferation than that observed after citric acid treatment.
