OBJECTIVE The purpose of this in vitro study was to evaluate the effect of two concentrations of homologous platelet-rich plasma (PRP) on the proliferative response of osteoblasts derived from a patient with aggressive periodontitis. METHODS 8.5 ml of venous blood were taken from 1 healthy and non-smoker volunteer. PRP was prepared following the protocol(More)
The prominent purpose of the study was the evaluation of the in vitro mitogenic effect of three different homologous platelet-rich plasma (PRP) preparations (PRPa, PRPb, PRPc) on three different lines of periodontal ligament (PDL) cells (PDL1,2,3), cultured alone or in combination with a demineralized freeze-dried allograft (DFBA). PDL cell cultures were(More)

Aim. To evaluate the effect of Low Level Laser Therapy (LLLT) on human gingival fibroblasts in terms of proliferation and growth factors' secretion (EGF, bFGF, and VEGF). Materials and Methods. Primary cultures of keratinized mucosa fibroblasts were irradiated by a Nd:YAG laser 1064 nm with the following energy densities: 2.6 J/cm(2), 5.3 J/cm(2), 7.9(More)
