Dental Erosion and Its Growing Importance in Clinical Practice: From Past to Present
Table 2
Ordinal scale used for grading severity of dental erosion on buccal and lingual surfaces of maxillary anterior teeth [25].
Grade
Criteria
0
No visible changes, developmental structures remain, macromorphology intact.
1
Smoothened enamel, developmental structures have totally or partially vanished. Enamel surface is shiny, matt, irregular, “melted,” rounded or flat, and macromorphology generally intact.
2
Enamel surface as described in grade 1. Macromorphology clearly changed, facetting or concavity formation within the enamel, no dentinal exposure.
3
Enamel surface as described in grades 1 and 2. Macromorphology greatly changed (close to dentinal exposure of large surfaces) or dentin surface exposed by ≤1/3.
4
Enamel surface as described in grades 1, 2 and 3. Dentin surface exposed by >1/3 or pulp visible through the dentin.
Note: approximal erosion, presence of “shoulder” and “cuppings” should be recorded.
