About

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

Enrollment: 168 patients

Sex: All

Ages: 18 to 80 years old

Volunteers: Accepts Healthy Volunteers

• Age ≥ 18 years
