THE PERMEABILITY OF THE GINGIVAL crevicular epithe lium has been a matter of
controversy for some time. Several workers have show that dyes, cells and par ticles can

THE PERMEABILITY OF THE GINGIVAL crevicular epithe lium has been a matter of controversy for some time. Several workers have show that dyes, cells and par ticles can pass from the gingival connective tissue into the gingival sulcus. 1-5. However, there appears to be conflicting evidence for the passage of substances from the gingival sulcus through the crevicular epithelium into the connective tissue.
Several indicators have been used to determine if substances pass through the crevicular epithelium. Car bon particles, 6 histamine, 7 trypan blue, 8 trypan blue and hyaluronidase, 9 pelican ink carbon suspension 1 0 and 3 H thymidine have been reported in the literature. These studies all suggest different degrees of permea bility of the crevicular epithelium based on different molecular weights and animal species. In contrast to the above findings, other workers 1 2, 1 3 have failed to
