Abstract:
Objective To determine the reliability of the tooth wear index in representing the profile of tooth cervical defect. Methods One hundred and ninety-three teeth with wedge-shaped defects were selected in 69 plaster casts. The sizes of every wedge-shaped defect were measured by using vernire caliper and the volumes of those were calculated. Otherwise, by weighting the restoration of defects, the real volumes of the 9 teeth defects were calculated by formulating. Results The formulation for calculatin of the real volume of the defects was presented as: volume = 0.4735 + 2.5948 X (deep of profile X height X broad of defects)/6. The profile of the defect was strongly related to the volume. Conclusions The value of one dimension measure of the wedge-shaped defects may present the tooth wear index.
