Oral findings in coeliac disease and Sjögren's syndrome.
OBJECTIVE
Both coeliac disease (CD) and Sjogren's syndrome (SS) have an autoimmune background and increased risk of oral mucosal and dental abnormalities. Individuals suffering concomitantly from CD and SS could even be at a higher risk.


METHODS
Oral mucosal and dental abnormalities were examined in 20 patients with CD + SS (mean age 61 years) and compared with age- and sex-matched controls with either CD or SS.


RESULTS
Oral mucosal changes were most common in SS (80%), followed by CD + SS (65%) and CD (40%). Coeliac-type dental enamel defects were found in 89% in CD + SS and in 88% in CD compared with only 25% in SS (P < 0.001). The median number of teeth was six in the CD + SS, 24 in the CD and 22 in the SS group. The DMF index was higher (P < 0.005) in the CD + SS than in the CD group. CD + SS was characterized by higher salivary flow rate (P < 0.001) and lower inflammatory focus score in the salivary glands (P < 0.01) than SS.


CONCLUSIONS
The co-occurrence of CD and SS should be recognized because of its effects on dental and oral mucosal health. A lower salivary gland inflammatory focus score and higher salivary flow rate in CD + SS than in SS suggests that a gluten-free diet treatment may alleviate autoimmune inflammation.
