Introduction: Patients with Primary Sjögren Syndrome (PSS) have a higher incidence of dental caries. As a conse- quence, radiolucent periapical lesions (RPL) may appear. Objective: To determine the prevalence of RPL in patients with PSS and to radiologically characterize the teeth associated with RPL. Methodology: Cross-sectional study involving patients with PSS, recruited at the Rheumatology Clinic (HUCAM-ES), who were initially submitted to a socioeconomic questionnaire and clinical evaluation of salivary flow. Subsequently, radiographs were obtained by a digital intraoral system with positioner for the periapical parallelism technique. Descriptive statistics were calculated by the mean and standard deviation for quantitative variables, and absolute and relative frequencies for qualitative variables. Chi-square test with 95% CI and Student t test were applied to compare patients with and without periapical lesion. Results: Over-all, 24 patients participated in the study and all were females (20-71 years). The mean number of teeth per patient was 23.3±3.1, with prevalence of dental RPL of 7.86%. Among all patients, 70.8% had at least one RPL. When comparing teeth with and without RPL, teeth with RPL showed higher percentage of treated canal and caries. Conclusion: According to the results, it can be concluded that RPL in patients with PSS is a frequent condition, especially when associated with teeth with obturated root canals.
