Therefore, [IL-17A.sup.-][IL-17F.sup.+] Th17 cells may also play important role in periodontal disease like [IL-17A.sup.+][IL-17F.sup.-] Th17 cell as both Th17 cells were correlated with the attachment loss
The sample consisted of subjects with a mean attachment loss
of 2.26 [+ or -] 1.71 which, according to the American Academy of Periodontology classification, (26) would be characterized as moderate attachment loss
51.1-87) average bleeding on probing score of 66.3% (95% C.I= 60.4-72.2) and average clinical attachment loss
of 2.5 mm (95% C.I= 2.35-2.6).
A number of studies reported rapid progression and higher severity of existing chronic periodontitis in HIV-seropositive patients with severe attachment loss
. It has been suggested that the preexisting periodontitis may be exacerbated in HIV-infected patients due to the severe immunosuppression and also HIV-infection is being considered as modifier of periodontal disease.
A population study (16) that used a self-reported questionnaire regarding alcohol consumption observed a significant relationship between alcohol, gingival inflammation and clinical attachment loss
, after controlling for major confounding variables.
Risk indicators for attachment loss

The peri- odontal examination included assessment of gingival index (GI) bleeding on probing (BoP) probing depths (PD) and clinical attachment loss
(1) Despite this, most dental professionals still use diagnostic tests developed in the early 1900's such as Disclosing Solutions, Bleeding on Probing, Pocket Depths and Radiographs, all of which are fraught with problems and none of which are predictive of future attachment loss
. Questions which come to our mind are; can traditional tests detect pathogenic biofilms?
