The Nestlé Research Center (NRC) in Lausanne, Switzerland, and the Nestlé Product Technology Centre (PTC), Orbe, Switzerland, formulated the placebo and coffee beverages. The placebo beverage was formulated with the aim to look, taste, and smell like coffee. Each sachet of the coffee beverage, contained 26.3% of regular Nescafé mixed with 73.7% of a non-dairy creamer (Table 1). Nestlé Nescafé was produced in the Shah Alam factory (Malaysia). The Nescafé recipe consists of 100% Robusta coffee (Table 1). Each sachet of the placebo beverage, contained 32.5% of a colored non-dairy creamer mixed with 67.5% of the same non-dairy creamer used for the coffee beverage (Table 1). Both the coffee and the coffee-like beverage contained 30 kcal per sachet.Table 1

Study beverage	Formulation	% Amount per sachet	Caloric content
Treatment	Regular Nestlé Nescafé	26.3%	30 kcal/sachet
Treatment	Non-dairy creamer (Coffee mate light)	73.7%	30 kcal/sachet
Placebo	Colored non-dairy creamer	32.5%	30 kcal/sachet
Placebo	Non-dairy creamer (Coffee mate light)	67.5%	30 kcal/sachet

Sachets were labeled with expiration date and randomization code for each subject. All boxes were kept under lock and key at room temperature in a storeroom at the study site.

Twenty specimens from each composite resin material were placed in each of the following solutions: tea (1 tea bag in 250 mL boiling water simmered for 5 min.; Rabea tea, AMS Baeshen and Co., Jeddah, Saudi Arabia), coffee (15 g of ground coffee in 250 mL of boiling water simmered for 5 min.; Nescafé, Nestlé UK Ltd., Staffordshire, UK), berry juice (200 mL of concentrated mixed berry in 1 L of chilled water; Vimto, Aujan Industries Co., Dammam, Saudi Arabia), and distilled water (n = 5) and stored in an incubator at 37 °C (Memmert, Schwabach, Germany) for 8 weeks with solution replacements every two weeks.

Staining of Resin Composites by Coffee

Check if the same lab product or an alternative is used in the 5 most similar protocols

The specimens were immersed in different immersion media, namely distilled water or coffee solution. The coffee solution was prepared with 25 grams of coffee powder (Nescafé, Nestlé SA, Vevey, Switzerland) and 250 mL of distilled water. The coffee solution was prepared with boiling distilled water, and only when it reached room temperature (24°C ± 1°C) did the staining process begin. Half of the specimens made with each composite resin and light-activation distance were immersed in the coffee solution (pH = 4.88). The other half represented the control group, which remained immersed in individual vials containing 3 mL of the distilled water (pH = 5.65), at 37°C for 7 days. The specimens submitted to the coffee solution remained immersed in 3 mL of the dye solution for 10 minutes a day at 37°C, under constant agitation on a shaker table (SK 0330-Pro, Dragonlab Laboratory Instruments Limited, Beijing, China). They were then washed with distilled water for 5 seconds, and remained immersed in distilled water. This cycle was repeated for 8 days, according to Borges et al. 3 (link)

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
