A simple test for salivary gland hypofunction using Oral Schirmer's test

OBJECTIVE: The objective of this study was to develop a test for detecting salivary gland hypofunction. STUDY DESIGN: Oral Schirmer's test was performed by placing a strip of filter paper on the floor of the mouth and measuring the wetted length after 5 min. The control group consisted of 70 healthy patients, while another group consisted of 61 patients with Sjögren's Syndrome (SS) and a third group of 31 patients who suffered from xerostomia caused by other pathologies. RESULTS: The mean saliva flow was 40.92 +/- 22.28 mm/5 min in the control group, 27.25 +/- 24.11 mm/5 min in patients with SS and 36.847 +/- 23.4 mm/5 min in the third group. The differences between the control group and the other two groups were statistically different (P > 0.001). CONCLUSIONS: The whole saliva test was used to distinguish between healthy adults and subjects with hyposalivation.
