Exudates and Transudates Categories.

	Cyst Fluid - Liquid material found in epithelial-lined closed cavities or sacs.
	Dentinal Fluid - The lymph or fluid of dentin. It is a transudate of extracellular fluid, mainly cytoplasm of odontoblastic processes, from the dental pulp via the dentinal tubules. It is also called dental lymph. (From Stedman, 26th ed, p665)
	Gingival Crevicular Fluid - A fluid occurring in minute amounts in the gingival crevice, believed by some authorities to be an inflammatory exudate and by others to cleanse material from the crevice, containing sticky plasma proteins which improve adhesions of the epithelial attachment, have antimicrobial properties, and exert antibody activity. (From Jablonski, Illustrated Dictionary of Dentistry, 1982)
