Abstract
The changes in the periodontal tissues of the rat, when submitted to inanition, were studied at body weight losses of 4, 8, 12, 20, 24, 28, 32, 36, and 40 per cent. Histological and histochemical methods were used to investigate the effects. It was possible to establish that the tissue changes started in the middle portion of the periodontal membrane, migrating in the beginning towards the alveolar bone and only in a later stage towards the cementum. There were no structural changes in the gingival mucosa. The results obtained are discussed in the light of the varying known metabolic rates of the various zones.
