Table 7 Modular evaluation system, module for diagnosing/monitoring occlusal/incisal [6-point ordinal scale], and non-occlusal/non-incisal [5-point ordinal scale]
From: A plea for the development of an universally accepted modular tooth wear evaluation system
Score | Description -occlusal/incisal | Description -non-occlusal/non-incisal |
|---|---|---|
0 | No (visible) wear | No (visible) wear |
1 | Wear within the enamel | Wear within the enamel |
2 | Wear with dentin exposure -horizontal less than 50 % of the area or -vertical loss of clinical crown height ≤1/3 | Wear with dentin exposure -less than 50 % of the area |
3 | Wear with dentin exposure -horizontal more than 50 % of the area or -vertical loss of clinical crown height >1/3 but ≤1/2 | Wear with dentin exposure -more than 50 % of the area |
4 | Wear with dentin exposure -horizontal complete loss of enamel or -vertical loss of clinical crown height >1/2 but ≤2/3 | Wear with dentin exposure -complete loss of enamel or -pulp exposure |
5 | Wear with dentin exposure -horizontal complete loss of enamel or -vertical loss of clinical crown height >2/3 | Â |
