Sexually transmitted microorganisms such as <jats:italic>Chlamydia trachomatis<\/jats:italic> can adhere to any mucosal surface and ascend to reach appropriate locations to survive and develop symptomatic infections.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and methods<\/jats:title><jats:p>To determine the presence of <jats:italic>C. trachomatis<\/jats:italic>, direct immunofluorescence of this microorganism was carried out in 76 randomly selected patients attending a periodontal clinic during a period of 1 year. Samples from the gingival sulcus and the pharynx were collected for detection of <jats:italic>C. trachomatis<\/jats:italic>. Patients who attended the periodontal clinic were divided into two groups: those without periodontitis and those with periodontitis.
