This investigation compares the Periotron 6000, Periotron 600, and ninhydrin area systems for quantifying gingival fluid. All systems have highly significant ( p <0.001) linear relationships between measurements and fluid volumes. Additional curvilinear components have virtually no clinically significant implications. Qualitative differences in fluid only have clinically significant implications for the Periotron 600. When both quantitative and qualitative properties of gingival crevicular fluid are being investigated, the Periotron 6000 is the system of choice.
