“…The amount of color changes of Optiglaze and control groups were not statistically different. Therefore, Optiglaze sealant had no significant effect on the color stability of the resin composites used, supporting the results of Cortopassi et al who applied different surface sealants to the same type of composite samples and concluded that, the surface sealant application did not provide any benefit in terms of color stability [42]. Nanofillers in Optiglaze might have contributed to the surface discoloration in terms of this outcome as long as the debonding of inorganic fillers form the resin matrix might have formed void formations on surface and incresed the surface roughness [28].…”

Objective. The aim was to assess the effect of surface sealants on the color stability of different composite materials. Methodology. 120 samples were prepared using Filtek Ultimate (3M, USA), Charisma Topaz (Kulzer, Germany), and Clearfil Majesty Es-2 Premium (Kuraray Noritake, Japan) composites. The samples were polished with polishing discs and divided by test groups (n=10 for each), regarding the sealant used; Permaseal (Ultradent Products, USA), Biscover LV (Bisco, USA), Optiglaze Clear (GC Corp., Japan) and control. The samples were discolored for 144 hours in coffee solution at constant 37°C, renewing daily. Color measurements were performed at the baseline, following the sealant application, and after discoloration procedure, using a spectrophotometer (EasyShade 5, Vita-Zahnfabrik, Germany). The collected L*C*h* coordinates were converted to corresponding L*a*b* coordinates and the color changes (∆E) were calculated. Results. All the sealants presented perceptible (> 1.2) and unacceptable (> 2.7) color changes. Biscover LV presented the lowest ∆E among all sealants (p <0.001). The highest ∆E was observed for Permaseal (p <0.001). Color changes for Optiglaze and control groups were similar (p ≥0.05). Filtek Ultimate presented the highest color stability (p <0.001), followed by Charisma Topaz and Clearfil Majesty. The combination of Filtek Ultimate with Biscover LV was considered to have the highest color stability, whereas the combination of Clearfil Majesty with Permaseal was considered the lowest, among all. Conclusion. Experimented sealants were considered relatively effective on color stability of resin composites depending on the type of the sealant and the composite material. However, the use of surface sealants may not be advantageous every time. Biscover LV have inhibited the level of discoloration, whereas Permaseal had an increasing effect generally.

“…The resin matrix monomers are hydrophilic and contain hydroxyl groups that form bonds with water molecules. This makes the resin matrix monomers absorb the liquid around them and increase the color change in the composite resin restoration [8], [18]. Only 55 respondents (55%) answered the question correctly because professional program students had not yet had knowledge regarding resin matrix monomers at the comprehension level.…”

“…The resin matrix has properties that can absorb the liquid. The water absorption that happens causes the composite resin to change color [8]. The higher amount of filler results in better color stability of the composite resin [9].…”

During the COVID-19 pandemic in Indonesia, all professional program students learning online and still expected to have good knowledge including dental materials. Color stability of anterior teeth restoration is the most important thing. Professional program students with a good level of knowledge were expected to support the use of composite resin towards patients without causing discoloration. The aim of this study was to assess the knowledge level of professional program students towards color stability of composite resin restoration in the Faculty of Dentistry, Universitas Trisakti in the COVID-19 pandemic era. This was a descriptive observational study using a cross-sectional approach. Data were collected using Google Form with a questionnaire that had been tested for validity and reliability. The sample was 100 professional program students who met the inclusion criteria and accepted informed consent. This study found that in the COVID-19 pandemic era, the knowledge level of 49 respondents (49%) was good, 37 respondents (37%) were fairly good and 14 respondents (14%) were less good. The majority of the professional program students of the Faculty of Dentistry, Universitas Trisakti were in the good category of knowledge about the color stability of composite resin restoration.

“…11 The effects of coating resin on the mechanical properties of GICs have been previously reported [12][13][14] but the studies on the effect of coating resin application on the coloration mainly remained limited to the composite resins. [15][16][17] This study aimed to evaluation of the color stability of coated and uncoated 4 different GICbased restorative materials after immersed in various staining solutions. The null hypotheses were (1) GIC type has no effect on color stability;…”

Objectives:The aim of this study was to determine the effect of coating on the color stability of different glass ionomer cements (GICs) after immersed in different children beverages. Materials and Methods:Four different GIC and a glass-ionomer coating material were used in this study. Disc shaped sixteen specimens of each GICs were done and divided into two groups, uncoated and coated (n=8). For color change, the specimens were immersed 7 day in the four solutions of cola, orange juice, chocolate milk and water. The color measurements were carried out before immersed solutions and at the end of the 1st and 7th days, using a spectrophotometer. The color change ΔE 00 was calculated using the CIEDE2000 formula. Data were analyzed by Kruskall-Wallis and Wilcoxon test (p<0.05). Results:The ΔE 00 values for all coated and uncoated GICs showed an increase in all solutions after 7 days of immersion. All the ΔE 00 values obtained from all the specimens immersed in cola were higher than the acceptability threshold. There was no statistical difference in terms of ΔE 00 values between the coated and uncoated specimens of the same GICs at same time periods. Conclusions:Coating of GICs exhibited relatively good color stability and protect from the discoloration. The staining effect of GICs should be carefully considered when selecting dental materials in pediatric dentistry.
