Dentists Make Larger Holes in Teeth Than They Need to If the Teeth Present a Visual Illusion of Size
Figure 8
Cut faces of four root ends prior to the endodontists’ operating on them (root tips removed and pink gutta percha visible), showing some of the measures we took.
For the upper left tooth we show the length of the long axis of the root acoss the root face (rl) and the length of the canal on the same axis (cl). For the upper right tooth, we show the width of the short axis of the root acoss the root face (rw), and the width of the canal on the same axis (cw). We repeated all measures after the teeth had been operated on by the endodontists, except that the central lengths and widths across the root face were of the cavities.
