The aim of this study was to compare the risk factors for caries between patients with primary Sjogren syndrome (SS) and those with non-Sjogren syndrome (NSS) salivary hypofunction and to identify the prevalence of incisal or cervical/root caries in each group.
This was a retrospective, cross-sectional study conducted at a single center between 2012 and 2015 for assessment of patients with possible SS. Two-hundred and twenty-five (225) patients (99 SS and 126 NSS) participated in the study.
Student t test and Wilcoxon's rank sum test were used to evaluate group differences in continuous variables and the χ
Patients with salivary hypofunction secondary to SS do have a greater caries risk compared with patients with salivary hypofunction caused by other factors. In this study cohort, this finding was not associated with salivary flow rates.
