  • Title: Lathyrogens and the role of collagen in the eruption of rat incisors.
    Author: Taverne AA, Lemmens IG, Tonino GJ.
    Journal: Arch Oral Biol; 1986; 31(2):127-31. PubMed ID: 3460538.
    Abstract:
    Collagen fibres in the periodontal ligament may have two functions: to resist displacing forces and to cause the tooth to erupt. Their function was examined in the continuously-erupting incisor of the rat using various concentrations and types of lathyrogens. Lathyrogens retarded tooth eruption and increased the quantity of salt-soluble collagen in the ligament, indicating inhibition of the maturation of salt-soluble (young) collagen into salt-insoluble (old) collagen, which would lead to reduction in the tensile strength of the fibres and decrease resistance to occlusal forces. The easy extractability of the teeth is explained by the greater susceptibility to lathyrogens of the fibres in the alveolar-related part of the periodontal ligament, compared with those in the other parts.
