Results Quantitative surface evaluation We observed a highly significant increase in surface roughness of polished enamel surfaces (S a of 9.16 ± 4.09 nm; S q of 11.68 ± 4.68 nm) following air-polishing with sodium bicarbonate (S a = 64.35 ± 36.65 nm; S q = 80.14 ± 44.80 nm) and erythritol (S a of 24.40 ± 7.42 nm; S q of 30.86 ± 9.30 nm; p < 0.001).
