Objective: To compare the color stability of the newer glass ionomer cements (GIC) when exposed to "Green tea" (GT), "Tulsi tea" (TT), and "Areca tea" (AT) using spectrophotometric analysis.
Materials And Methods: We selected commercially available GC Fuji IX GP EXTRA and Ketac Universal for this study. Eighty disc-shaped samples were made using a mold, which were immersed in the freshly prepared test solutions (distilled water, GT, TT, and AT) for 15 minutes per day for 60 days. The color estimation was done using a spectrophotometer.
Results: GC Fuji IX samples had a significantly higher mean difference in ΔE value than Ketac Universal when immersed in GT, AT, and control (P<0.001, 0.018, and <0.001), respectively. With GC Fuji IX, GT and AT stained more than TT and control solutions. Samples of Ketac Universal showed a significantly higher mean difference in ΔE values when immersed in AT, followed by GT, TT, and control.
Conclusion: Within the study's limitations, we conclude that both the GICs exhibited staining over time on exposure to all the test solutions. Ketac Universal demonstrated lower staining potential than GIC Fuji IX GP Extra for GT and AT.

Aim: The aim of this study was to compare the surface roughness and color stability of polyetheretherketone (PEEK) with those of conventional interim prosthetic materials like polymethylmethacrylate, bis-acrylic composite, and rubberized diurethane dimethacrylate, following immersion in solutions of varying pH value.
Materials And Methods: A total of 320 circular discs with 10 mm diameter and 2 mm height were divided based on the fabrication ( = 80)-group A: polymethylmethacrylate; group B: bis-acrylic composite; group R: rubberized diurethane; and group P: hot-pressed PEEK-and were subjected to baseline measurement of roughness ( = 40) and color ( = 40) using 3D profilometer and UV-Vis spectrophotometer, respectively. Later, 10 samples from each group were immersed in distilled water, black coffee, green tea, and Pepsi, respectively, for 120 days, and measurements of roughness and color were repeated.

Regularly consuming orange-fleshed sweet potatoes (OFSP) is widely recognised as an effective way to treat vitamin A deficiency (VAD), particularly in low-income countries. Unfortunately, cultivars of OFSP are poorly disseminated in most countries in sub-Saharan Africa, where VAD is a major cause of blindness. This study was conducted to evaluate the effect of the genotype-environment interaction (GEI) on the performance and stability of the yield components of OFSP cultivars to trigger their adoption by farmers.

The genetic basis of type 1 red-flesh color development in apple () depends upon a particular allele of the gene. Interestingly, type 1 red-flesh apples are fully red after fruit set, but anthocyanin pigmentation in apple fruit cortex may decrease during fruit growth and maturation, leading to variable red patterning and intensities in the mature cortical flesh. We developed a histogram-based color analysis method to quantitatively estimate pigmentation patterns.

Objective: This study aims to examine color properties of repairs made with various composites on restorations produced through additive-manufactured resin composites (AM-RC) and zirconia (AM-Z) or subtractive manufacturing (SM) after coffee thermocycling (CTC).
Materials And Methods: Disk-shaped specimens (Ø10 × 2 mm; N = 120) were fabricated using six different material groups: additively manufactured resin composite (AM-RC) materials (Crowntec [C], NextDent [ND]), additively manufactured zirconia (AM-Z) materials (Lithoz [LI], INNI-Cera [IN]), and subtractively manufactured (SM) materials (CEREC Tessera [ALD], Vita Enamic [EN]). Subsequently, each group was further subdivided into two subgroups (n = 10) based on the type of repair using two different composites resins: Clearfil Majesty Posterior (CL) (n = 60) and Filtek Z350 (FZ) (n = 60).
