Abstract

Background: Bone healing on defect requiring the cells to form new bone. Fibroblast growth factor -2 belong to one of signaling control that play part in differentiation of fibroblast to osteoblast cell. Hydroxyapatite application on bone healing will aid bone regeneration as structure. Application of Sardinella longiceps oil that contain EPA and DHA as immunodulator could accelerate and optimize inflammatory phase in bone healing. Purpose: The aimed of this study to determine the effectivity of the combination of Sardinella longiceps oil and application of hydroxyapatite on the expression of fibroblast growth factor -2 (FGF-2) in bone healing process. Materials and Methods: The experimental units (male wistar rat, n=20) were devided into two groups, control (K) and treathment (P) groups. Treathment groups were given Sardinella longiceps oil per oral seven days before the surgery to make the defect, and continued for seven days later. Control groups were not given Sardinella longiceps at all. All of the wistar rat were have two defects in their right femur, which is use hydroxyapatite (K+ and P2) and no use hydroxyapatite (K- and P1). Defect was made as big as half diameter of round bur in femur. Rats were sacrificed seven days after surgery, and femur were sliced transversally and performed immunohistochemistry staining with Anti-bFGF Polyclonal antibody (Bioss®). Examination were done under light microscope. Data were analyzed using one-way Anova for FGF-2 expression. Result: Sardinella longiceps oil increased the mean of FGF-2 expression on P2 group : 15,29±5,251, compare to K- : 5,57±2,070 , K+ : 12,14±3,976 and P1 : 8,14±1,676 (P<0.05). Conclusion: The combination of Sardinella longiceps oil and hydroxyapatite application effective the expression of fibroblast growth factor-2 in the process of bone healing.

Abstract

Background: Periodontitis is complication of DM in chronic state. Periodontitis susceptibility increase threefold in patient DM compared non-DM. Debridement with SRP alone is less effective in DM. Hyperbaric Oxygen Therapy (HBO) has the effect of increasing insulin sensitivity and synthesis of collagen. Collagen is the largest extracellular matrix supporting periodontal tissue. Stchopus hermanii contains condrotin sulfate serves to inhibit the formation of mixed periodontopatogen bacteri. Purpose: To determine the therapeutic effects of HBO 2,4 ATA 3x3’ interval 5’ 7 days and stichopus hermanii against periodontal ligament collagen density in the healing process of periodontitis with DM. Materials and Methods:The experiment design is factorial design. Rats are inducted with STZ 65 mg/kgBB to make them suffer DM and are inducted with P.gingivalis 1x109sel/ml for 5 days straight to make them suffer periodontitis, 20 male Wistar rats were divided into 4 groups. K0 (control group), K1(STZ+P. gingivalis), K2(STZ+P. gingivalis+Stichopus hermanii), K3(STZ+P. gingivalis+HBO), and K4(STZ+P.gingivalis+stichopus hermanii HBO) after treatment on day 52, all groups were sacrificed and done making preparations for the HPA of the mandible bone. Results: Data were analyzed using chi-square, Kruskal wallis, and Mann Whitney U with 95% significance level (p = 0.05). increase level of collagen significantly K1(1 ± 0.00) - K2(2±0.00), dan K1(1 ± 0.00) - K4(2.5 ± 0.289).Conclution:Therapy HBO combination of 2.4 ATA 3 x 30 with 5 minutes air breaks for 7 days and gel Stichopus hermanii3% effective on the Densityof collagen in the periodontal ligament healing process periodontitis with DM.

Abstract

Background: One of a bone defect fillers is ahydroxyapatite. Hydroxyapatite can be obtained from Anadara granosa shells extract that have high calcium content. The mineral content can be used as a bone filler material for bone grafting. However, the material is not known bioviability to against periodontal tissues so that was needed bioviability testing. This bioviability testing using mesenchymal stem cells as mesenchymal stem cells can differentiate into periodontal tissues. Purpose: To determine bioviability Anadara granosa shell extract on mesenchymal stem cells. Materials and Methods: This study was conducted using post-only control group design. Mesenchymal stem cells in 96 wells were divided into a control group of cells (n=7), media controls (n=7), and treatment (n=7). The treatment group were given various doses of the Anadara granosa shell extract with a concentration 54 mg/ml, 27 mg/ml, 13.5 mg /ml and 6.75 mg/ml. The mesenchymal stem cells were incubated for 24 hours before and after treatment. Once given MTT, the optical density is read by ELISA reader and calculated the percentage of viability. The cell viability data were analyzed with KruskalWallis statistical test, Mann-Whitney. Results: From the results showed that an increase in cell viability to Anadara granosa shell extract. Increased cell viability starting treatment group concentration of 54 mg/ml (23,,67%), 27 mg/ml (57,43%), 13,5 mg/ml (68,87%), 6,75 mg / ml (81,92%). The highest cell viability at concentrations of 6,75 mg/ml (81,92%). Conclusion: Bioviability extract blood clam Anadara granosa shell have the highestconcentration of 6,75 mg/ml and bioviabilitas lowest cell at a concentration of 54 mg/ml.
