Evaluation of the concordance of sialometry and salivary glands scintigraphy in dry mouth patients

摘要

INTRODUCTION: Many diagnostic tests are used to evaluate dry mouth patients, especially the ones with Sjögren?’s Syndrome, to whom these tests are part of classification criteria for scientific studies. AIM: Thus, the concordance between results of sialometry and salivary glands scintigraphy was evaluated; if positive, it would enable the choice of one or the other for diagnosis. PATIENTS AND METHOD: Seventy-two dry mouth patients were divided into non-Sjögren?’s Syndrome group, primary Sjögren?’s Syndrome group and secondary Sjögren?’s Syndrome group. The concordance among sialometry and scintigraphy results was evaluated by Kappa test. RESULTS: It was observed that their concordance was equal or near to zero. CONCLUSION: It is not possible to make a choice between these tests and both should be performed.
