Bioviabilitas Ekstrak Gracilaria sp terhadap Stem Sel Mesenkimal sebagai Terapi Adjuvant Periodontitis
Keywords:
Bioviability, Gracilaria sp, mesenchymal stem cellAbstract
Background: Gracilaria Seaweed extracts are known to have an antibacterial content that
can inhibit the growth of Porphyromonas gingivalis bacteria. P.Gingivalis are dominant in
chronic periodontitis as a cause of periodontal tissue damage that can be inhibited by using
materials that contain antibacterial effect. Terms of materials to be applied in the oral cavity
must be biocompatible, through toxicity tests, one with bioviability test. In this study
bioviability test performed on media mesenchymal stem cells. Purpose: To determine
bioviability Gracilaria seaweed extract against mesenchymal stem cells as adjuvant therapy
of periodontitis. Materials and Methods: study design was post test only control group
design. Mesenchymal stem cells in 96 wells were divided into a control group of cells (n=6),
media controls (n=6), and treatment (n=6). The treatment group was given Gracilaria
seaweed extract with a concentration of 2.5%, 5%, 10%, 20% and 40%. Stem cells were
incubated 24 hours before and after treatment. Once given MTT, optical density read with an
ELISA reader then calculated the percentage of living cells. Toxic material when living cells
<50% and not toxic when living cells >50%. Living cell data were analyzed by statistical test
Kruskal Wallis and Man Whitney. Result: Viability cell at 2.5% concentration is 68.59%, 5%
concentration = 29.67%, 10% concentration = 4.43%, 20% concentration = 2.5% and 40%
concentration = 0.96 %. Conclusion: Extract of seaweed Gracilaria proven not toxic at 2.5%
concentration and proved toxic at 5%, 10%, 20% and 40% concentration
