OPG and RANKL Signal Transduction in Osteoblast Regulation Post Application Extract Collagen in Osteogenesis

Background and Aim: The current goal of periodontal therapy is to achieve periodontal regeneration. Important factor for periodontal regeneration is to promote bone formation, nowadays used bone replacement. The used of xenograft materials as gold standard for periodontal tissue regeneration using type I collagen bone graft has been widely developed. The main organic component in fish scales is type I fibril collagen, which are same as with component in bones. Specific markers of bone formation are the expression of osteoblast, osteoclast, osteoprotegerin (OPG), and receptor activator of nuclear factor κB ligands (RANKL). The purpose of this study is to assess the expression of OPG and RANKL after application of extract collagen from gourami (Osphronemus gouramy) scales. Materials and Methods: Thirty-two experimental 3-month-old male Wistar albino rats (150g and 200g) were randomly divided into four groups: 7-day control group, 7-day fish collagen group, 14-day control group and 14-day fish collagen group. The sockets were filled with blood (control group), whereas 10 mg to 30 mg extract collagen was added until the sockets were fully occupied (treatment group). Results: The ANOVA test showed a significance level of 0.000 (p <0.05). Conclusion: Expression of OPG enhanced and expression of RANKL lowered after application of type I collagen from gourami scales, accelerating osteogenesis.
