Microleakage of Silorane-based Resin Composite in Comparison with Methacrylate-based Composite in Class II Open Sandwich Restorations: An in vitro Study

Abstract

Introduction: This in vitro study aimed to evaluate the effect of different monomer systems on microleakage in class II composite open sandwich restorations with and without a separating agent placed between the nanofilled resin modified glass ionomer and the resin.

Oxidative decolorization of carmosine with acidic chloramine-T: Spectrophotometric, kinetic and mechanistic chemistry

“…The nature of active oxidizing species of CAT depends on the pH of the medium and the reaction condition. Chloramine-T is a source of positive halogen and this reagent has been exploited as oxidant for a variety of substrates in both acidic and alkaline media [10,11,[14][15][16][17][18][19][20]. Although a large numbers of various substrates have been oxidized by CAT, very few oxidation kinetic investigations of dyes have been carried out with CAT.…”
