Identification of four Treponema species in subgingival samples by nested-PCR and their correlation with clinical diagnosis.

The relationship between different species of oral Treponemas and inflammation in periodontal disease progression is complex. The purpose of this study was to analyze and compare the subgingival plaque samples collected from periodontally healthy subjects and from chronic gingivitis and periodontitis patients in order to detect the presence of T. denticola, T.

Identification of Treponema denticola in subgingival samples by PCR technology and its correlation with clinical diagnosis.

Treponema denticola has been associated with gingivitis and chronic periodontitis. The aim of this study was to identify Treponema denticola in subgingival samples using PCR technology and to correlate it with clinical diagnosis of subjects. The study was carried out on seventy patients (20-84 years of age; mean age, 45.
