Introduction
Currently, there are two latest composite resin materials: nanofiller and nanohybrid composite resins. Additional compositions in nanofiller and nanohybrid composite resins are expected to significantly impact color stability. Color stability in a composite resin can be influenced by two factors, such as intrinsic and extrinsic elements, which also influence each other. Camphorquinone is the main cause of internal staining in composite resins, whereas tannins and curcumin are the highest causes of external staining in composite resins to date. Color stability can be evaluated using several tests, including color change test, filler leaching test, water absorption, resin solubility test, and surface roughness test.

Material and methods
This study was conducted to analyze a correlation of barium leaching with color stability of nanofiller and nanohybrid composite resins.

Results
A total of 20 specimens divided into 4 groups: group 1 (nanofiller) and group 2 (nanohybrid) composite resins (control groups) immersed in artificial saliva, and group 3 (nanofiller) and group 4 (nanohybrid) composite resins immersed in turmeric solution and coffee solution, and subjected to tooth brushing treatment, were analyzed in this study. Each group of composite resins was subjected to FESEM/EDX (field emission scanning electron microscopy with energy-dispersive X-ray) and colorimeter evaluation.

Conclusions
A correlation between color stability and barium leaching was observed, with a significant conversion strength of 64.7% (strong correlation) (p < 0.05). A correlation between color stability and barium leaching was observed, with a significant conversion strength of 64.7% (strong correlation) (p < 0.05). Conclusion: Color stability of nanofiller composite resins was better than that of nanohybrid composite resins.
