“…To assess the occurrence of discoloration that simulates events in the oral cavity, several studies have suggested that more than one dye agent should be used separately. In this study, the exposure treatment was established as turmeric, coffee, and brushing with toothpaste [1][2][3][4][6][7][8][9][10].…”

“…Intrinsic factors include the type of matrix, size, composition and properties of fillers, coupling agent, and photoinitiator [5]. Extrinsic factors include foods and beverages that contain dyes, such as curcumin and tannin as well as cigarettes [6][7][8][9]. In addition to extrinsic coloring agents, several studies have described that due to the brushing process, the teeth can indirectly develop a composite resin surface roughness, which can trigger color changes.…”

“…In this study, spectrophotometers are used because they are considered to be more accurate in measuring color change than colorimeter. [10] Spectrophotometers contain monochromators and photodiodes that measure the reflectance curve every 10 nm or less. [11] The spectrophotometer used in this study (V-770 UV-Visible/NIR Spectrophotometer, Easton, Maryland, USA) has wavelength ranged from UV to NIR (190–2700 – option 3200 nm).…”

Aim: The aim of this study was to compare the effect of chlorhexidine mouthrinse on the color stability between three different types of composites. Materials and Methods: A total of 30 samples of size 10-mm length, 1-mm width, and 1-mm thickness were prepared on a customized microglass slide from each of the composite materials and immersed in 20 ml of distilled water followed by incubation at 37°C for 24 h. The samples were divided into three groups ( n = 10) – Group I: A nanofilled composite, Filtek Z350XT (3M ESPE, St. Paul, USA); Group II: A microhybrid composite, Polofil Supra (Voco GmbH, Germany); and Group III: A nanoceramic composite, Ceram.x Sphere TEC (Dentsply, Konstanz, Germany). Baseline color values were recorded using a spectrophotometer (V-770 UV-Visible/NIR Spectrophotometer, Easton, Maryland, USA) according to the laboratory scale. After baseline color measurements, ten randomly selected specimens from each group were immersed in 20 ml of 0.2% chlorhexidine mouthrinse (Rexidin Plus, Aurangabad, India) for 24 h. The postimmersion color values of the samples were then recorded, respectively, using the same spectrophotometer. Statistical Analysis Used: The statistical analysis was done using one-way ANOVA followed by Tukey's post hoc test. Results: Statistically significant difference was observed between the mean color change values in the three groups ( P < 0.05) with the highest color change (delta E [ΔE]) in Group III (Nanoceramic composite). The ΔE for Group I (Nanofilled composite) was 3.16, Group II (Microhybrid composite) was 3.32, and Group III (Nanoceramic composite) was 3.51. Conclusion: All the three types of composites displayed color changes after immersion in mouthrinse, but the color shift depended on the material used, and the nanofilled composites (Filtek Z350XT, 3M ESPE, St. Paul, MN, USA) had higher color stability.

“…(3) The unpredictable discoloration is one of the common causes that lead to the replacement of resin composites. (4) Generally, the color change of composites is divided into two types of internal and external color changes; internal color changes are caused by physical and chemical reactions in the inner layers of the restorative material, and external color changes are due to the consumption of colored food and drinks, smoking, and poor oral hygiene. (2) To prevent and treat periodontal disease and for effective caries control and due to the difficulties in achieving an acceptable level of bacterial plaque control mechanically, the use of chemical agents as a supplement is recommended; the simplest of chemical agents are mouthwashes.…”

Background and Aim: The purpose of this study was to examine the effect of alcohol and non-alcohol mouthwashes on the color change of two types of bleach shade composite. Materials and Methods: Twenty-two samples of IPS empress direct composite (Ivoclar Vivadent, Schaan, Liechtenstein) and 22 samples of Vitalescence snow white composite (Ultradent Products, South Jordan, UT, USA) were prepared in 10 mm diameter and 2 mm thickness. The specimens were polished with Sof-Lex (3M ESPE, USA) abrasive papers in supra fine, fine, and medium sizes. The specimens were then stored for 24 hours in distilled water at 37°C, and an initial colorimetric assay was performed using SP64 spectrophotometer. Samples were randomly divided to be placed in 20 ml of alcohol and non-alcohol Listerine mouthwashes and were incubated at 37°C for 24 hours. The color of the specimens was again measured, and color change (ΔE) was calculated. Data were analyzed using two-way analysis of variance (ANOVA) at 95% confidence level. Results: None of the mouthwashes caused clinically significant discoloration in the samples. The effect of both mouthwashes on composite discoloration was statistically significant (P=0.0001), and the interaction between the mouthwash and type of restorative material was significant (P=0.0001). Conclusion: IAccording to the findings of this study, alcohol mouthwashes cause more discoloration in composite resins.
