Objectives: This study aimed to ascertain the impact of charcoal toothpastes on the colour stability of resin composites loaded with nanoparticles. Methods: Thiry disc-shaped specimens were made utilizing a mould of 8 mm diameter and 2 mm thickness. Fifteen samples each were made for both bulk-fill (Tetric-N-Ceram) as well as nano-filled composite resins (Z250, Filtek Z250 XT), all in A3 shade. Then, three sets of ten discs each were created from the samples and were exposed to brushing with three toothpastes-Healthvit activated charcoal, Colgate total charcoal deep clean, Colgate total (control). A reflectance spectrophotometer was utilized for assessing colour stability. The data were statistically analysed using the Shapiro Wilks test, ANOVA and paired t-test. Results: Among the toothpastes, Colgate total charcoal deep clean showed greater colour shift in the groups, whereas Healthvit activated charcoal toothpaste showed the least colour change. Conclusion: The resilience of resin composites' colour was affected by the dentifrice utilised. Tetric N Ceram demonstrated decreased colour stability, both before and after exposure to dentifrices. In comparison to Healthvit activated charcoal toothpaste, Colgate charcoal toothpaste exhibited lowest colour retention capacity.
