First Posted : December 17, 2012
Last Update Posted : June 10, 2014
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.
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
