Evaluation Of Staining Susceptibility Of Aesthetic Restorations Following Mouthrinses – An In Vitro Study

AIM: The purpose of this study is to determine the staining susceptibility of nano-filled composite materials following the use of two different mouth rinses. METHODS AND MATERIALS: The study sample consists of two different nanocomposites of shade A2. 30 samples of nano-filled composites (15 each) with a diameter of 8 mm and thickness of 2mm will be prepared using a metal ring. The samples will be divided into two groups: GROUP A (Tetric N-Ceram), GROUP B (3M ESPE Filtek). Each group has 5 subgroups: Subgroup A: control (normal water), Subgroup B: Betadine 2 % Mint Gargle, Subgroup C: Colgate Plax, Subgroup D: Hexidine, Subgroup E: Peroxyl. All the samples will be immersed in respective mouth rinses for the respective period, then the samples will be placed in distilled water after the testing period and the procedure will be carried out for one week. The color stability differences between the nanocomposites while using two different mouth rinses will be measured by spectrophotometer. Data will be analyzed by ANOVA test. RESULTS: The color difference (ΔE*) of the resin materials ranged between 5.46000 and 0.58400 after one week of assessment. CONCLUSION: Tetric N-Ceram has more staining susceptibility than 3M-ESPE nano-composites. Among the different mouth rinses, betadine has more staining potential followed by Colgate Plax, CHX, and Hydrogen peroxide.
