Placenta Extract Gel as a Periodontal Local Delivery Drug

Overview

Introduction: Periodontal disease is one of the most prevalent global chronic disorders. Pathology affecting the structure surrounding teeth results in inflammation initiated by bacterial aggregation and alteration in their profile. conventional periodontal therapeutics has focused on the control of etiologic agents, thereby promoting healing, repair of tissues delivery of therapeutic agents into the pocket act as drug reservoirs which could alter pathogenic flora and promote its repair and wound healing. Aim of the study: Evaluate the effect of locally delivered placenta extract gel as an adjunct to scaling and root planning in the treatment of periodontal pocket. Methodology: 30 patients with grade B stage II periodontitis will be selected from the Faculty of Dentistry Suez Canal University outpatient clinic and divided into 2 equal groups. Group I: will have scaling and root planning. Group II: will have scaling and root planning with placenta extract gel locally delivered in the periodontal pocket. All clinical parameters (plaque index, gingival index, probing pocket depth, and clinical attachment) and lab investigations (vascular endothelial growth factor and fibroblast growth factor) will be measured at 0,1 and 3 months. All results will be tabulated and statistically analyzed using the SPSS program.

Group I: (control group): where subgingival scaling and root planning will be performed and the pocket will be allowed to heal with secondary intention. Group II (test group): where subgingival scaling and root planing, and 1ml of human placental extracts gel\* adsorbed in 30 beads of gelatin foam of 1sq. mm, will be placed into the pockets with the help of a probe to fill the sulcus to the deepest point \& coepak will be placed. patients will be recalled after seven 12 days to remove the coePak. A customized acrylic stent will be fabricated for each patient to provide a reproducible insertion axis for the periodontal probe. The stent will be grooved in an occlusal-apical direction for the above-mentioned purpose. Lab assessment: The area will be isolated with cotton rolls, gingival crevicular fluid will be collected using a paper point three times for each pocket, and samples will be stored at -80°. Vascular endothelial growth factor and fibroblast growth factor will be measured for the two groups using the ELISA technique. Clinical assessment: The following parameters will be recorded for the two groups: plaque index, gingival index depth, probing pocket, and clinical attachment.(Silness and Löe, 1964, Löe and Silness, 1963) Measurements will be taken from the stent to the deepest probing depth to record. Probing pocket depth (PPD) while Relative Attachment level (RAL) will be recorded by subtracting the length of the deepest probing depth from the stent from the length from the stent to the cemento-enamel junction All the clinical parameters will be recorded on day 0,1 months and 3 months and all results will be tabulated and statistically analyzed
