Patients with vasculitis present a poor oral health: results of the online cross-sectional survey from Canada (VASC-TOOTH Survey).

To describe oral health complications and related quality of life in patients with vasculitis. Survey to assess clinical variables, pertinent to oral and dental health in patients with vasculitis and using the Oral Health Impact Profile 14 (OHIP14) questionnaire. 226 patients answered the survey. Globally, 179 (79.2%) patients reported good oral and dental health before the vasculitis diagnosis, while 92 (40.7%) patients reported a worsening since the diagnosis of vasculitis. Patients with a worsened oral health had a longer disease duration (10.0 (1.0) vs. 7.4 (0.7) years; p < 0.05), and had more relapses in the previous 2 years (34.8% vs. 16.4%; p < 0.005). The median OHIP14 score was 4 (IQR: 0-10); 97 (48.7%) patients scored > 4 points. Patients with Takayasu arteritis and Behçet disease showed worse OHIP14 scores, had a longer disease course but were younger than those with better scores or other vasculitis diagnoses. A high proportion of patients with vasculitis, especially those with Takayasu arteritis or Behçet disease, reported oral or dental complications, with subsequent impaired oral health-related quality of life.
