Table 2.

Four transformations (1–4) of the tooth tissue volumes resulting in 10 outcomes (1 and 2–4a–c)

1. Total: pulp + predentine + hard tooth tissue
2. x/(total − x)	3. x/total	4. (x + y)/total
(a) Pulp/(total − pulp)	(a) Pulp/total	(a) (Pulp + predentine)/total
(b) Predentine/(total − predentine)	(b) Predentine/total	(b) (Pulp + hard tooth tissue)/total
(c) Hard tooth tissue/(total − hard tooth tissue)	(c) Hard tooth tissue/total	(c) (Predentine + hard tooth tissue)/total

x and y are either pulp, predentine, or hard tooth tissue shown in outcomes a–c for the transformations 2–4
