AbstractBackground and Objectives: Oral disorders, frequently observed in patients with primary Sjögren's syndrome, can profoundly affect patients' daily lives and well-being, as oral health represents a fundamental part of general health. Saliva plays an essential part in maintaining and protecting oral health, so the decrease in its quantity and quality leads to chronic oral discomfort alongside a broad spectrum of problems. The objective of the present study was to evaluate the oral health of patients with primary Sjögren's syndrome and establish its effect on the different domains of their oral health-related quality of life (OHRQoL). Materials and Methods: The research was designed as an observational case-control study with prospective data collection. Eighty patients, divided into two groups based on their oral status, participated in the study. All subjects underwent a complete oral examination. The OHRQoL was assessed using the Oral Health Impact Profile-14 (OHIP-14). Results: The most prevalent oral manifestation was exfoliative cheilitis, while 30% of subjects complained of chewing and swallowing difficulties. The OHIP-14 summary score was significantly higher in the patients with oral lesions (26.0 (5.0) vs. 17.0 (4.0), respectively; p < 0.001). Oral manifestations, systemic involvement, medication, and periodontal indexes were significantly associated with OHIP-14 scores. Conclusions: Patients with oral alterations had a substantially decreased OHRQoL. These findings emphasize the importance of oral diseases for patients' well-being. Therefore, it is essential for dentists to be included in the multidisciplinary teams managing primary Sjögren's syndrome, as improving patients' oral status would lead to better oral health and enhanced OHRQoL.
