| Popis: | Introduction: The challenge in restorative dentistry is related to changes in the colour of composite over time when exposed to a variety of common beverages, which necessitates additional expenses for the patients. Aim: To compare the colour changes of various composites currently available on the market after exposure to commonly consumed beverages. Materials and Methods: This in-vitro study was conducted from May 2022 to December 2022 in the Department of Conservative Dentistry and Endodontics at Karnavati School of Dentistry in Gandhinagar, Gujarat, India. A total of 120 disc-shaped composite pellets, with 40 specimens for each type of composite (nanohybrid, nanofilled, and microhybrid), measuring 6×2 mm, were prepared and divided into four subgroups based on the beverages used (Distilled water, coca-cola, Tea, and Coffee). The samples were submerged in the respective beverages and kept at 37°C for seven days. Colour assessment was performed using a spectrophotometer before and after immersion. The obtained Commission International de l Eclairage (CIE) ΔE values were recorded after measuring the CIE L*a*b* values. Data analysis was conducted using Statistical Package for Social Sciences (SPSS) software version 20.0, utilising a paired t-test, post hoc Tukey’s test, and one-way Analysis of Variance (ANOVA).
