Brief Summary

Growth factors are defined as small proteins that trigger a cellular response after binding to cell receptors; Tissue engineering is now clinically applicable in a commercially available system involving the use of recombinant human platelet-derived growth factor. The objective of this study is to evaluate clinical and radiographic parameters in bone defects treated with platelet-derived growth factor in combination with allograft. Our hypothesis: Defects treated with DFDBA and rhPDGF-BB have better clinically and radiographic results that the defects treated with DFDBA and saline solution.

Outcome Measures

Primary Outcomes (7)

  • Probing depth

    The distance from free gingival margin to sulcus depth, ≥4 millimeters (mm)

    Initial and six months after surgery

  • Bleeding on probing

    Method to asses gingival inflammation. Gingival health is defined as \< 10% bleeding sites

    Initial and six months after surgery

  • Gingival Recession

    The distance from the soft tissue (gingiva or alveolar mucosa) margin to cemento-enamel junction, ≥1 millimeters (mm)

    Initial and six months after surgery

  • Clinical Attachment Level

    The distance from the cemento-enamel junction to the tip of a periodontal probe during periodontal diagnostic probing, ≥2 mm (millimeters)

    Initial and six months after surgery

  • Gingival Phenotype

    Gingival phenotype is determined by gingival thickness and keratinized tissue width. Probe visible: thin (≤1 mm). Probe not visible: thick (\>1mm).

    Initial and six months after surgery

  • Plaque control record

    O'Leary index is used for assessing oral hygiene skills of the patient

    Initial and six months after surgery

  • Radiographic Measurements

    Cemento-enamel junction (CEJ)-Defect Base (DB): The distance of the cementoenamel junction at the base of the defect. Cemento-enamel junction (CEJ)-Bone crest (BC): The distance of the cemento-enamel junction to the crest of bone. Cemento-enamel junction (CEJ)- Root apex (RA): The distance of the cemento-enamel junction to root apex. Lineal Bone Growth (LBG) = CEJ to base of defect at baseline - CEJ to base of defect at 6 months. %BF: Percent bone fill was calculated by dividing LBG by the depth of the original bone defect

    Initial and six months after surgery
