Conditions

Ankylosing Spondylitis, Periodontitis

Brief summary

1. Our hypotheses on the relationship between periodontitis and AS are as follows; * The prevalence of periodontitis is higher in AS patients group than that of non-AS control group * Anti-TNF-α therapy would favorably affect the disease course of periodontitis. 2. Based on our hypotheses, the specific objectives of the present proposal are as follows; * The primary objective is to compare the prevalence rate of periodontitis between AS patient group and non-AS group. * The secondary objectives will be: * To observe the carriage rate of P. gingivalis in AS and non-AS groups * To identify clinical parameters associated with the severity of periodontitis in AS group. * To compare the progression of periodontitis at weeks 12 and 24 between AS and non-AS groups or between AS patients with and without anti-TNF-α treatment

Exclusion criteria

* Subjects having received periodontitis treatment including scaling within 6 months before study participation. * Subjects with a history of taking antibiotics including prophylactic anti-tuberculosis agents within 3 months before study participation. * Subjects with a hitory of taking immuno-suppresives (methotrexate, leflunomide, tacrolimus, cyclosporin, or azathioprine) or any dose of glucocorticoids (oral or pareneral) within 3 months before study participation. * Subjects with a history of diabetes mellitus. * Subjects with aggressive periodontitis requiring open flap debriment at enrollment immediately. * Subjects with a hitory of clinical inflammatory bowel disease. * Subjects with active infection, which can make an influence on the levels of acute phase reactants. * Subjects with any other condition to render the patient unable to understand the scope of the study or preclude the patient from following the protocol in the physician's opinion.
