Biocompatibility of Portunus Pelagicus Hydroxyapatite Graft on Human Gingival Fibroblast Cell Culture

INTRODUCTION: Crab shell (Portunus pelagicus) has the potential to be a source of hydroxyapatite biomaterials that used as bone grafts. Before clinical application, crab shell graft should be tested for its biocompatibility in vitro on human gingival fibroblast. AIM: This study aimed to determine the biocompatibility of Portunus pelagicus hydroxyapatite graft on human gingival fibroblast cell culture. MATERIAL AND METHODS: Human gingival fibroblast cell cultures were divided into control group and treatment group with the addition of hydroxyapatite graft powder from Portunus pelagicus at a concentration of 100 ppm, 50 ppm, and 25 ppm. The synthesis process of hydroxyapatite was conducted by heating at 1000°C then characterizing the compound with SEM-EDX. All samples were incubated in α-MEM medium, then were given MTT material. The cultures on the plate were examined using ELISA reader. The results were analyzed using a Oneway Anova. RESULTS: The percentage of living cells throughout all treatment group shown results that exceeded the LD50 parameter. The highest percentage of living cells was at 25 ppm concentration group. CONCLUSION: The hydroxyapatite graft powder from crab shells is biocompatible with human gingival fibroblast cell culture.
