Purpose: This study aimed to examine the effect of beverages at different temperatures on the coloring of composites.
Materials And Methods: A total of 48 cylindrical samples, 24 of which were prepared from 2 composite materials (G'aenial; Estelite Σ Quick), were included in the study. The sample dimensions were standardized at 2 x 10 mm2. After the polishing, the initial color measurements were performed using a spectrophotometer. The samples were divided into 3 subgroups as distilled water, hot coffee (60 °C) and cold coffee (0 °C) (n=8). During the 7th and 30th days, the samples were immersed in the solutions for 15 min every day. Color measurements were repeated on the 7th and 30th days. Data were analyzed using a two-way analysis of variance, followed by the Tukey post-hoc test (p<0.05).
Results: The highest color change was detected on the 7th and 30th days in the G-aenial anterior microhybrid composite immersed in hot coffee (p<0.001). The application of hot and cold coffee applications did not make a statistically significant difference in the coloration of the Estelite Σ Quick composite samples at the end of the 7th (p=0.346) and 30th (p=910) days.
Conclusion: Hot drinks had a more coloring effect on restorations. This coloration was quite evident in the microhybrid composite.

Background: The consumption of coffee as a beverage and honey as a sweetener is prevalent worldwide, with each having potential health implications. However, studies on the combined effect of coffee and honey on blood pressure, heart rate, and blood glucose level are lacking.
Objective: The objective of this study is to determine whether a three-day consumption of honey- sweetened coffee will significantly alter the systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), heart rate (HR), and fasting blood glucose (BG) levels in young, healthy female adults.

Acrylamide (AA) has been classified as a toxic, harmful, and carcinogenic substance since 2002, and therefore it is currently widely studied. When functional amino and carbonyl groups of asparagine and reducing sugars are condensed into Schiff bases, they are transformed into AA molecules at temperatures >120 °C. This mechanism is known as the Maillard reaction and is considered the main AA pathway.

Background And Aim: Achieving the aesthetic standards in tooth-colored restorative materials requires close attention to their color, translucency, and resistance to discoloration. This study aimed to evaluate the effect of sintering temperature on color stability and translucency in zirconia systems with low, high, and ultra-high translucencies.
Methods: This experimental study was conducted on 60 zirconia disks with low, high and ultra-high translucencies (n = 20 per group), each group divided into subgroups to be sintered at either 1450°C or 1550°C (n = 10 per subgroup).
