AMAÇ: Çocukların en sık tükettiği 5 farklı içeceğin fiberle güçlendirilmiş rezin kronlar üzerinde renk değişimi (ΔE) bakımından etkisini değerlendirmektir. YÖNTEM: Bu çalışmada, toplamda 60 adet maksiller üst santral kesici diş için üretilmiş fiberle güçlendirilmiş rezin kron (Figaro Crowns, Inc., Woodbury, MN, USA) kullanıldı. Başlangıç renk değerlerinin spektrofotometre cihazı ile ölçülmesinin ardından kronlar ilk grup kontrol grubu, 2. grup kola, 3. grup şeftali aromalı soğuk çay, 4. grup vişne suyu, 5. grup portakal suyu ve 6. grup çikolatalı süt olmak üzere rastgele 6 gruba ayrıldı (n=10). Kronlar bir hafta boyunca içecekler içerisinde inkübe edildi. Test periodu sonrası distile su ile yıkanan ve kurutulan kronların renk ölçümleri tekrarlandı ve renk değişim değerleri hesaplandı. İçeceklerin renk değişimi üzerindeki etkisinin değerlendirilebilmesi için tek yönlü varyans analizi (ANOVA) kullanıldı. İkili karşılaştırmalar için Tukey testi yapıldı. İstatistiksel anlamlılık eşiği p=0,05 olarak kabul edildi. BULGULAR: Bütün kronlar, içecek maruziyeti sonrasında renk değişikliği gösterdi, gruplar arasında istatistiksel olarak anlamlı farklılık bulundu (p 0,05). SONUÇLAR: Çocuklarda özellikle ön dişlerin fiberle güçlendirilmiş rezin kronlarla restore edildiği durumlarda, renk stabilitesinin devamlılığı için hasta ve ebeveynlerin içecek tüketimi sonrası oluşabilecek renklenmeler konusunda bilgilendirilmesi önem taşımaktadır.

“…In the present study, the color measurement was calculated with CIE Lab because it is a repeatable method and sensitive for small color changes similar to the method used in the abovementioned studies. [ 15 ] Based on the human eye's capability in differentiating color, variations in color values were distinguished using three different intervals, including Δ E <1 undetectable with the human eye, 1.0< Δ E <3.3 distinguishable by a skilled individual, and Δ E >3.3 easily observable with naked eyes. The Δ E value of 3.3 or below is clinically regarded as acceptable in dentistry.…”

Background: One of the drawbacks of tooth-colored dental restorations is their discoloration over time. The present study aimed to determine the effect of four categories of pediatric medications, including analgesics, antibiotics, anticonvulsants, and multivitamins, on two types of tooth-colored dental materials, namely, composite resins and glass ionomer cements. Materials and Methods: In this in vitro study, a total of 40 specimens with disc shapes (with a diameter of 5 mm and thickness of 2 mm) were prepared from each material and immersed in eight different drugs for 2 min three times a day for 1 week. The values of the baseline color were calculated based on the CIE (International Commission on Illumination) L*a*b* system. After 7 days, ΔE values were calculated. Two-way analysis of variance was employed for statistical analysis. Statistical significance was defined at 0.05. Results: Statistical analysis showed that there were significant differences between ΔE and different restorative materials as well as ΔE and drug types (P < 0.001). Conclusion: According to the results of this in vitro study, all the four types of drugs caused the discoloration in all the restorative materials, and the color change values were affected by the type of used drug and restorative material.

“…(10) The chemical characteristics of the resin and the cross-linking degree can influence the water sorption of composites. (11,12) Water sorption can cause expansion and plasticization of the components, hydrolysis of silane-coupling agents, loss of bonds between the filler and resin matrix, and formation of micro-cracks, leading to internal color change in the composite. (5) The presence of BIS-GMA and TEG-DMA monomers in the resin matrix can cause more water sorption and discoloration in composites with this type of resin matrix, which is clinically unacceptable.…”

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.
