Discussion

In vitro comparison of bleaching effects on enamel surfaces and elemental changes, suggesting varying impacts of different products.

Bleaching treatments significantly altered enamel surface morphology and mineral content.
Calcium reduced to 1.42–7.85 at% with BlancOne Ultra+, while controls maintained higher levels around 11.5 at%.
Scanning electron microscopy identified surface roughness and fissures, indicating substantial structural changes post-treatment.
All bleaching protocols led to different degrees of demineralization, with high-concentration products causing the most significant losses.

Buzatu et al. (2025) studied this question.
