Stain susceptibility of a giomer and a particulate-filled injectable composite with one-step and multi-step polishing techniques, and color recovery after brushing and repolishing.

Researchers compared how easily three composite materials stained when exposed to coffee and whether brushing or repolishing could recover their colour, using different polishing techniques. G-ænial Injectable resisted staining better than other materials, and multi-step polishing improved stain resistance and colour recovery across all composites.
