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
Study Arms (3)
Allograft
ACTIVE COMPARATORWill be used Demineralized cancellous allograft 250-1000um
Saline Solution
SHAM COMPARATORThe saline solution will be used for hydrate the bone graft 20 minutes before the placement at the defect
rhPDGF-BB (GEM21, Lynch Biologics)
EXPERIMENTALThe rhPDGF-BB will be used for hydrate the bone graft 20 minutes before the placement at the defect
Interventions
At this intervention the periodontal defect will be treated with allograft and rHPDGF-BB (GEM21)
This will be used as the control group
