Objective: The objective of this investigation was to assess the effects of different denture cleansers and distilled water on color stability of self-polymerized (SP) and heat-polymerized (HP) acrylic denture base materials. Methods: Specimens were prepared from HP (Lucitone 199) and SP (Rapid Repair) acrylic resin denture base materials and distributed into different groups/15 each. Specimens were immersed in distilled water as control and in three different denture cleansers (Corega, Polident, and StainAway Plus) according to the manufacturer's specifications and immersion was repeated 7 times over 7 days. All specimens in different groups were measured for color stability using a spectrophotometer against a white background under a standard illumination of D65. Statistical analyses were performed using one and two-way analysis of variance and independent t-test. Results: No significant color change in HP acrylic base material immersed in denture cleansers compared to the con...

Effect of Different Food Coloring Additives on the Color Stability of Microabraded, at-Home Bleached and Resin Infiltrated Tooth

Objective: Color stability of at-home bleaching and resin infiltration is one of the main goals of these procedures. The primary aim of present study was to evaluate color stability of at-home bleaching and resin infiltration to four common colorants present in Indian foods (turmeric, beetroot, coffee and artificial food colorants). Materials and Methods: 128 human maxillary central incisors were used in this study. Teeth were randomly divided into groups as (i) subjected and (ii) not-subjected to microabrasion. Further, the teeth in each group (abraded/non-abraded) were randomly distributed to four subgroups (16 teeth/subgroup). Subgroups were control, bleached, combined treatment with at-home bleaching followed by resin infiltration and infiltrated. After treatment procedures the teeth were immersed in the four different food colorants. Objective photographic color change evaluation from pre-/ post staining was done using the CIEDE2000 formula. Statistical Analyses: Data were anal...

The color stability of acrylic denture teeth is important for the denture wearers as this reflects the overall appearance of their face. The aim of this study was to evaluate the color stability of the acrylic denture teeth when immersed in turmeric and black coffee solutions. Sixty acrylic denture teeth were used in this study. These teeth were divided equally into three groups: a control group (distilled water), turmeric and black coffee solutions. The color changes were recorded after Day 1, Day 7 and Day 15 of immersion period. The color measurements were performed by using Coral dental shade guide and a visible spectrometer. The visual assessment from the shade guide showed that the acrylic denture teeth immersed in turmeric solution had the most color change compared to the black coffee solution. The spectrometer analysis showed that the change in reflectance value was higher for acrylic teeth immersed in turmeric solution compared to black coffee solution, indicating more color changes in turmeric sample compared to black coffee sample. It was concluded that acrylic denture teeth showed less color changes when immersed in the black coffee solution compared to turmeric solution and that the amount of color change also increased proportionally with time.

The purpose of this study is to evaluate in vitro the color stability of composite resins when exposed to beverages with high coloring contents from the Amazon region. 240 samples from four different composite brands (Natural Look, Z350, 4Seasons and Opallis) of hue A3 were fabricated using an acrylic matrix. The samples were stored in distilled water at 37ºC for 24 hours. The initial color (T0) was registered using a Canon EOS Rebel XTi 10 mp camera, and then the samples were divided into four groups (n=15): G1 (coffee), G2 (açaí juice), G3 (energetic guaraná) and G4 (control - distilled water). The samples were exposed to solutions of DES (6hs) and RE (18hs) and placed in a double boiler under constant agitation, at 37ºC for 30 days. The samples were immersed in the coloring solutions for 15 minutes daily. After 7, 15 and 30 days, new photographic registers were made (T1, T2 and T3). The images were analyzed using Corel PHOTO-PAINT 12 software to identify the colors through the HS...
