Comparative effects of conventional and electronic cigarettes on discoloration and surface roughness of gingiva‐colored dental materials

Conventional cigarette exposure resulted in more significant color changes and surface roughness increases in gingiva-colored materials compared to electronic cigarettes. Indirect composite resins demonstrated lower color stability than porcelains. Patients with gingiva-colored porcelain and composite resin restorations should be informed about color and surface roughness changes due to smoking.
