Abstract

Background: Tooth discoloration in one or more anterior teeth can cause significant aesthetic problem for patients because it affects the smile that relates to a person’s self-confidence. Thus, external bleaching is a viable treatment alternative. Discoloration stains on teeth are caused by smoking and the consumption of pigmented beverage such as coffee. Purpose: This case reports an external bleaching caused by an unhealthy lifestyle. Case: A 26- year-old female television presenter wanted to treat yellowish dark shade of her teeth and this made her feel less confident due to the yellowish dark shade teeth. Case Management: Teeth discoloration was managed with external bleaching using hydrogen peroxide 40%. After the treatment, the teeth shade increased from yellow-brownish to A2 with Vita Classic shade guide. Conclusion: The case report shows that external bleaching treatment produces brighter shade and increase self-confidence of the patient so she feels very satisfied.

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.
