1. Pigs, held by undernutrition to a weight of about 5.5 kg till they were a year old, were then rehabilitated on an excellent growing ration, and killed when they were fully mature.

2. Undernutrition of this degree of severity delayed the growth and development of the teeth, but relatively less than that of the body or the jaws.

3. The teeth became abnormally sited and the shape of the mandible changed.

4. During rehabilitation, some of the crowns and most of the roots of the molar teeth failed to reach their proper size.

5. Some of the molar teeth remained permanently impacted and out of alignment.

6. The fine structure of the teeth, particularly of those parts formed during the period of undernutrition, was still abnormal when the animals were killed.
