Abstract

Background: Tooth discoloration is a prevalent issue that significantly impacts an individual's self-confidence. Fortunately, dentists offer highly effective and non-invasive teeth whitening techniques that use higher concentrations of hydrogen peroxide (HP) of around 35% to 40%. These techniques can help resolve the problem of teeth discoloration better than at-home methods designed to deliver faster results. This is particularly helpful when immediate whitening is required. Purpose: This case study aims to report cases of in-office external bleaching of discolored teeth. Case: A 29-year-old woman complained about the yellowish shade of her teeth, which made her feel less confident due to the yellowish color. Case Management: The management for discoloration of teeth was done with dental bleaching using 40% hydrogen peroxide. As a result of the treatment, the desired tooth color increased from 3M1 to 1M1 Vita 3D Master and from Opalescence no.6 to 4. Conclusion: In-office dental bleaching is a highly effective treatment option for correcting tooth discoloration that dental professionals widely use. The procedure can significantly improve the appearance of discolored teeth and increase self-confidence of the patient.

Abstract

Background: Dental caries affects 57.6% of the Indonesian population, with Enterococcus faecalis found in 80% of deep caries cases. Conventional materials used in vital pulp therapy (VPT), such as calcium hydroxide, have limitations including transient antibacterial action and poor sealing capacity. This prompts the exploration of alternative materials like epigallocatechin-3-gallate (EGCG), a polyphenol from green tea with antimicrobial activity, and tricalcium silicate (C₃S), a bioactive cement known for dentin regeneration potential. Purpose: This review evaluates the synergistic antibacterial potential of EGCG and C₃S combinations against E. faecalis, and assesses their feasibility as an alternative in VPT. Review: EGCG disrupts bacterial membranes, inhibits biofilm formation, and suppresses virulence factors, but lacks remineralization capability. Conversely, C₃S promotes dentin repair and creates an alkaline antibacterial environment, though its efficacy diminishes over time. Their combination compensates for each other’s limitations: EGCG enhances antimicrobial potency while C₃S provides long-term alkalinity and regenerative support. Conclusion: The EGCG–C₃S combination exhibits synergistic antibacterial and regenerative effects, offering a promising alternative to current VPT materials.
