Abstract

Background: Brackets in fixed orthodontic appliances are mostly made from metal or stainless steel. Maintaining oral hygiene by brushing the teeth with toothpaste during orthodontic treatment is important. One of the ingredients in toothpaste, sodium fluoride, can cause degradation of the stainless-steel surface, which has the potential to corrode or release metal elements. Purpose: the purpose of this study is to describe the Nickel and chromium ion release of stainless-steel brackets against toothpaste use in orthodontic treatment by means of narrative review. Review: The main corrosion products of stainless-steel brackets are nickel and chromium. Toothpaste detergents contain sodium lauryl sulfate, which can cause the release of nickel ions due to the presence of sodium ions, which can trigger redox reactions. In addition, the fluoride content will combine with hydrogen to produce hydrofluoric acid, which can damage the oxide layer on orthodontic wires, resulting in the release of metal ions such as nickel and chromium. The effects of the release of these ions can be carcinogenic, cause hypersensitivity reactions, and cause cytotoxicity. Corrosion causes the dissolution of filler metal, resulting in weakened bracket material and increased friction, leading to delayed tooth movement. Conclusion: Toothpaste can affect the release of nickel and chromium ions in stainless steel brackets in the presence of sodium and fluoride.

Abstract

Introduction: Recurrent Aphthous Stomatitis (RAS) is the most common oral lesion in Banjarmasin, with a prevalence of 45.42%. Streptococcus sanguinis (S. sanguinis) is thought to be one of the factors causing RAS. One natural ingredient that is often used by the people of South Kalimantan is the Haruan fish. The high Haruan fish consumption will eventually leave fish scales that have the potential to pollute the environment if not addressed immediately. Fish scales contain chitin, which when deacetylated produces chitosan, which has antibacterial properties. Objectives: The purpose of this study was to determine the effectiveness of the chitosan from the scales of the Haruan fish (Channa striata) at inhibiting S. sanguinis growth. Methods: This study used a randomized pretest-posttest with control group design using five treatments. The five treatments were subjected to liquid dilution using the UV-Vis Spectrophotometer method to obtain minimum inhibitory concentration (MIC) and a solid dilution test using the Total Plate Count method to obtain minimum bactericidal concentration (MBC). Results: The results showed that Haruan scale chitosan proved to be effective as an antibacterial against S. sanguinis, with a MIC of 1.25% and a minimum lethal concentration of 2.5%. One-Way Anova test results showed significance for the MIC test (p = 0,000) and MBC test (p = 0.000; p < 0.05). Conclusion: Chitosan from Haruan fish scales is both inhibitory and lethal to S. sanguinis.

Abstract

Rongga mulut merupakan habitat berbagai macam mikrooganisme salah satunya Streptococcus mutans. Streptococcus mutans merupakan bakteri utama penyebab terjadinya karies gigi. Streptococcus mutans berkoloni membentuk biofilm serta membentuk coaggregasi dengan bakteri lain yang dilindungi oleh lapisan matriks Exopolysaccharide (EPS). EPS berperan dalam melindungi berbagai spesies mikroba yang berada didalamnya serta dapat memberikan pasokan nutrisi. Di dalam biofilm mikroorganisme melaksanakan komunikasi dengan inducer (quorum sensing) yang memungkinkan bakteri lain merespons terjadinya perubahan lingkungan serta melaksanakan pembentukan biofilm.
