DISCUSSION
The results of this case-control study suggest that –unlike the situation in RA- there is not a positive association between SpA and periodontitis in Colombian patients. We even found a lower prevalence of periodontitis and less severe periodontitis in comparison to healthy controls. Moreover, all periodontal characteristics evaluated including clinical parameters, antibodies anti P. gingivalis and bacterial identification were not increased in SpA patients as compared to controls.
Several studies on the association between periodontitis and RA have been published 18. Periodontitis has been considered a condition with an increased prevalence in individuals with RA
