M a t e r i a l s a n d m e t h o d s An EMS viscometer was used to measure viscosity. A viscosity standard fluid and artificial saliva (Saliveht) were used. R e s u l t s Viscosities of 20.14 mPa s (SD ± 0.04) and 4.26 mPa s (SD ± 0.08) were recorded for the standard fluid and Saliveht, respectively. These values did not substantially differ when the measurements were repeated five times at different time points and when using different sets of tubes, spheres and viscosity standard fluids, as well as various amounts of the fluids. C o n c l u s i o n The use of a newly developed EMS viscometer demonstrated high repro- ducibility. This device might make chairside measurement of salivary viscosity simple.
