Preparation
First, the extent of incisal or occlusal wear for a single tooth was evaluated by the following four-point scale, the “tooth-wear index”:
- 0: no wear or negligible wear of enamel;
- 1: obvious wear of enamel or wear through the enamel
to the dentine in single spots; - 2: wear of the dentine up to one-third of the crown
height; - 3: wear of the dentine up to more than one-third of the crown height; excessive wear of tooth restorative material or dental material in the crown and bridgework, more than one-third of the crown height.

Calculation
Your personal tooth-wear index is calculated as follows:
10x G1 + 30xG2 + 100xG3 divided by the total number of teeth (G0 + G1 + G2 + G3)
