Table 1 The result from using 3D analysis for comparing student’s prepared cavities (n = 61) with the standard cavity (RMS is root mean square)
Type of cavity | Deviation from the standard prepared cavities | ||
|---|---|---|---|
Minimum deviation (mm) | Maximum deviation (mm) | RMS (Median, min-max) | |
Occlusal cavity | –1.92 | 1.97 | 0.27 (0.18, 0.40) |
Proximal cavity | –1.34 | 2.49 | 0.29 (0.20, 0.57) |
