The Passage of Tissue Fluid into the Clinically Healthy Gingival Pocket

Abstract

Fluorescein injected intravenously is found 30 seconds later in clinically healthy gingival pockets in dogs. Its presence on other eipthelial surfaces was not observed, except in areas where the gum had been damaged, or where the gum covers non-erupted teeth. The passage of tissue fluid into gingival pockets as a possible defense mechanism is pointed out as is the possibility that the presence of tissue fluid in gingival pockets is a source of calcium in the formation of subgingival calculus.
