Abstract

Background: Streptococcus mutans (S. mutans) is a Gram-positive bacterium that plays a role in dental caries. Plaque and biofilm formation can be chemically cleaned using mouthwash, such as chlorhexidine gluconates (CHX) 0.2%, which is the gold standard. Another alternative can be developed to inhibit S. mutans biofilm formation by using Lactobacillus plantarum probiotic, which has antibiofilm potency by producing antimicrobial substances. Purpose: This study tested the biofilm inhibition to determine the Inhibitory Concentration that can inhibit 50% of biofilm formation. Methods: This research was conducted as an in vitro experimental laboratory study. Biofilm inhibition testing was performed by using the microdilution method on biofilms formed in 96 well microplates with 0,1% crystal violet staining. Lactobacillus plantarum FNCC 0020 was diluted to several concentrations: 12.5%, 25%, and 50% against Streptococcus mutans biofilm induced by 3% sucrose. The test results in optical density were read using a spectrophotometry with a wavelength of 650 nm. were determined using the GraphPad Prism sigmoidal dose-response method. Results: There is antibiofilm activity of Lactobacillus plantarum FNCC 0020 against Streptococcus mutans, and the inhibitory effect against Streptococcus mutans biofilm showed of 42.43%. Conclusion: Lactobacillus plantarum FNCC 0020 at 50% has biofilm inhibitory activity compared to other concentrations but is less effective than 0.2% CHX.

Abstract

Background: Vital pulp therapy is a treatment to repair and maintain pulp vitality. Calcium hydroxide is the gold standard in pulp capping materials. Calcium hydroxide has advantage antibacterial. However, calcium hydroxide has some disadvantages such form a layer liquefaction necrosis. Blood clam shells contain 98.7% calcium carbonate. Calcium carbonate (CaCO3) content becomes a good source of calcium can be used as a bone repair material. Purpose: To review effect nano CaCO3 from Anadara granosa shell induced odontoblast-like cells as a pulp capping candidate. Nanoparticles CaCO3 has advantages such as high surface area, low toxicity, biocompatibility, biodegradability, pH-sensitivity, and osteoconductivity. Reviews: Nano CaCO3 from Anadara granosa are promising to promote odontoblast-like cells formation. Conclusion: Nano CaCO3 its potential to influence odontoblast-like cells, which play a crucial role in dentin regeneration and repair.
