Method: The association between sialometry and other clinical examinations were investigated in a cross-sectional study. A total of 179 dry mouth patients showing hyposalivation who underwent a clinical examination were enrolled in this study. Multiple regression analyses were employed to examine the relative con-tributions of clinical and immunological factors including age, gender, parotid sialography, labial Salivary gland biopsy, anti-Ro/SS-A antibodies, and anti-La/SS-B antibodies to the resting (RSF) or stimulated saliva flow rate (SSF). Results: An increase of the stage of sialography, the grade of a labial biopsy, and the presence of anti-La/SS-B antibody had a significant correlation with a decrease of sialometry. Results of the multiple regression analysis showed that age (standardized coefficient = -0.244), grade of lip biopsy (-0.189), and anti-SS-B antibody (-0.171), were significantly associated with the RSF. The stage of sialography (?0.423) and age (-0.169) were significantly related to the sialometry in the SSF according to a multiple regression analysis. Conclusion: The results of this study suggest that the measurement of RSF reflects the immunological factors and SSF reflects the damage to the parotid gland.展开更多

Methods In this study, dried samples of freshly produced saliva from 78 patients with established SS according to European Community criteria and 80 healthy controls were examined by light microscopy. The crystallization was classified into 4 types according to the ferning phenomenon: uniformity, branching, spreading and integrity (type I normal and type Ⅱ,Ⅲ,Ⅳ abnormal ). Then, the 78 patients underwent lebial salivary gland biopsy. According to Tarpley’s classifica- tion, minor salivary gland biopsy (≥2 + ) was considered to be positive . Results 1. The sensitivity of SFT was high (70/ 78 = 89. 74% ). And the specificity wes also high (67/80 = 83. 75% ). 2. Abnormal SFT was observed in 70/78 (89. 74% ) samples from patients group and in 13 /80 (16. 25% ) samples from healthy controls. The differences of SFT in patients group versus controls were statistically significant (P< 0. 01 ). 3. The sensitivity of SFT and mini labial gland biopsy had no significant differences (P > 0. 05) as diagnostic tests in SS. Conclusion SFT was simple, sensitive and specific as diagnostic test in SS suspect patients just as mini labial gland biopsy.展开更多
