Surface Score Criteria
Facial 0 No erosion. Surface with a smooth, silky-glazed appearance and absence of developmental ridges possible.
1 Loss of surface enamel. Intact enamel found cervical to the erosion and concavity on enamel whose breadth clearly exceeds its depth, thus distinguishing them from tooth abrasion. Undulating borders of the lesions are possible. Dentin is not involved.
2 Involvement of dentin for less than one half of the attacked area of the tooth surface.
3 Involvement of dentin for more than one half of the attacked area of the tooth surface.
0 No erosion. Surface with a smooth, silky-glazed appearance and absence of developmental ridges possible.
Occlusal/Lingual 1 Slight erosion. Rounded cusps, edges of restorations rising above the level of adjacent tooth surface, grooves on occlusal aspects. Loss of surface enamel. Dentin is not involved.
2 Severe erosion, more pronounced signs than in grade 1. Dentin is involved.
