Objectives: The aim of this study was to assess, in vitro, the color of teeth exposed to different mouthrinses for a prolonged period.
Methods: Bovine teeth were distributed in four groups: control, alcohol-containing mouthrinse (Listerine(®)), alcohol-free mouthrinse (Oral-B(®)) and chlorhexidine mouthrinse (Periogard(®)). The teeth were submitted to two cycles of staining and artificial aging.
Objectives: The aim of this study was to assess the optical properties of orthodontic elastic ligatures under the influence of exogenous pigments contained in the daily diet.
Material And Methods: For the analysis, colorless (clear) elastic segments (ORTHO Organizers, lot 660625A10) were used as received from the manufacturer, and were divided into 8 groups of 3 segments each. Each group was immersed in 200 mL of a solution containing a determined substance, as follows: distilled water (control group), Coca-Cola®, Pomarola brand tomato sauce (Cica®), açai, Jasmine® brand green tea, Royal Blend® black tea brand, Pilão® brand coffee and Palmares® wine brand.
Objective: To evaluate the color stability of six esthetic archwires at different time periods and their fluorescence.
Materials And Methods: Samples were evaluated after 7, 14, and 21 days of immersion in staining solution. Color measurements were performed by means of a spectrophotometer according to the Commission Internationale de I'Eclairage L*a*b* system, and color changes (ΔE*) and National Bureau of Standards units were computed.
