Notes:
A new device, the Periotron 6000®, has been proposed to estimate small amounts of gingival crevicular fluid. In the present investigation, small volumes of four different liquids (saline, saliva, plasma, and crevicular fluid) collected with small capillaries have been delivered on to Periopaper® strips. The amounts of liquids on the strips were determined with the Periotron.High correlations between the fluid volumes and the Periotron readings were found. A calibration curve of the measurements made with crevicular fluid with its 5% tolerance and confidence limits is given. The slope of linear regression found in our investigation was at 3.5 nl per unit, thus significantly below that described by the manufacturer (5 nl/unit). Taking into account this fact, the Periotron, however, is a very reliable device to study gingival crevicular fluid in clinical investigations.
