OBJECTIVES: The aim of the study was to examine whether oral health as an infection focus could mediate disease course in patients with Behçet's disease (BD).
METHODS: In the study, oral health of 194 BD patients was examined at baseline and follow-up periods. The reasons for last dental visits were recorded as tooth extraction or regular control visits/planned treatments at the end of follow-up period. The Behçet's disease severity score was calculated with higher scores indicating a more severe course. Mediation analysis was carried out to assess the effects of oral health on disease severity score at follow-up period in the study.
RESULTS: Dental and periodontal indices were found to be higher at follow-up visit compared to those of baseline (P < 0.05). Disease severity score was found to be higher in males (5.3 ± 2.4) compared to females (4.4 ±2.5) in the whole group (P = 0.005). Moreover, patients having tooth extraction at their last dental visit and patients with dental caries had a more severe disease course (5.4 ± 2.4; 5.5 ± 2.5) compared to others (4.2 ± 2.3; 4.4 ± 2.4; P < 0.0001). In multiple mediation analysis, disease severity score was a dependent variable and was directly mediated by male gender (B = -0.8822, P = 0.0145) and indirectly mediated through the presence of dental caries (B = 0.9509 P = 0.0110) and need of tooth extraction (B = 0.8758, P = 0.0128).
CONCLUSION: Both presence of dental caries and need of tooth extraction were observed to be effective mediators for a more severe disease course in BD. Therefore, better oral health should be aimed to eliminate microbial factors, which are a part of pathogenic processes.
