Aim: Recent evidences of the presence of reduced stimulated salivary flow rate and altered saliva composition in oligoarticular juvenile idiopathic arthritis (o-JIA) suggest a specific damage to the salivary glands. The aim of this cross-sectional study was to investigate whether reduced salivary flow rate could be related to age and gender at disease onset in o-JIA.
Methods: A total of 57 Caucasian patients (41 females and 16 males) aged 5 to 16 years affected by o-JIA were consecutively enrolled in the study. Information on medication intake, dietary and oral hygiene habits were gathered through a standardised questionnaire. All patients underwent oral and sialometry examination.
Conclusion: Early onset disease would seem to be associated with salivary glands impairment. Regular dental and salivary gland function assessments may be highly recommended in o-JIA patients considering that saliva collection is a non-invasive and inexpensive procedure.
