Desmodonte renewal in baboons (Papio papio)]

Turnover of desmodontal ligament is analysed in the Baboon using labeling, biochemical and histological techniques. In Baboons, as previously observed in rodents, turnover of proteins labelled by 3H glycine may be described by a single exponential after the ninth day, the half life of which is more than two weeks. Biochemical data show that proteins renewed are mostly collagen.
