Collagen in dentin.

E C Munksgaard

    Journal De Biologie Buccale
    |June 1, 1979
    PubMed
    Summary
    This summary is machine-generated.

    Dentin contains type I collagen and type I trimer, with cultured odontoblasts producing both equally. In vivo analysis confirmed type I trimer is present in dentin, though likely in smaller amounts than type I collagen.

    Area of Science:

    • Biochemistry
    • Dental Science
    • Molecular Biology

    Background:

    • Collagen is a crucial structural protein in connective tissues.
    • Odontoblasts are specialized cells responsible for dentin formation.
    • The specific collagen types within dentin require further elucidation.

    Purpose of the Study:

    • To identify the types of collagen synthesized by cultured odontoblasts.
    • To determine the presence and relative abundance of collagen type I trimer in vivo dentin.

    Main Methods:

    • Culturing odontoblasts and analyzing synthesized collagen.
    • Extracting collagen from unerupted bovine teeth for in vivo analysis.

    Main Results:

    • Cultured odontoblasts synthesized both collagen type I and type I trimer in nearly equal proportions.

    Related Experiment Videos

  • Analysis of in vivo dentin confirmed type I trimer as a constituent.
  • Type I trimer appears to be present in smaller amounts compared to type I collagen in vivo.

    • Conclusions:

    • Dentinogenesis involves the synthesis of both collagen type I and type I trimer.
    • Type I trimer is a component of dentin, contributing to its structural integrity.
    • Further research may clarify the specific functional role of type I trimer in dentin.
