title: Autoradiographic study of 3-h-proline incorporation by rat periodontal ligament, gingival connective tissue and dental pulp.
abstract: The rates of 3-H-proline incorporation by the rat periodontal ligament, the gingival connective tissue and the dental pulp were studied by autoradiography.  The rate of 3-H-proline incorporation by the periodontal ligament was 2.8 times higher than by the gingival connective tissue and 5 times higher than by the dental pulp.  These differences were significant (p smaller than 0.01).  The pattern of 3-H-proline  incorporation by the periodontal ligament was significantly different (p smaller than 0.01) from that by the gingival connective tissue and the dental pulp.  The latter two tissues exhibited a similar pattern of 3-H-proline incorporation.  The ratio of the rates of 3-H-proline incorporation by the three tissues did not correlate with the ratio of the cellular densities in the same three tissues.
