Gene Expression Profiles in Chronic Periodontitis
Gene Expression Profiles in Chronic Periodontitis: A Gene Network-based Microarray Analysis
Current concepts of the causes of periodontitis implicate a bacterial infection as the primary cause of the disease. Several bacterial species residing in a biofilm on tooth surfaces are closely associated with periodontitis. Chronic periodontitis (CP) is initiated and sustained by bacterial plaque, but host defense mechanisms play an integral role in its pathogenesis.
Gene expression profiling is a powerful means of generating comprehensive genome-level data sets on diseases such as cancer, asthma, rheumatoid disorders and periodontitis, and provides significant insight information for these diseases. Gene expression profiling may provide an evidence for involving genes in the pathogenesis of CP and generate further information other than clinical signs and symptoms of CP.
The aim of this study was to identify gene-expression patterns of patients with chronic periodontitis by whole-transcriptome gene-expression analyses.

Patients with Chronic Periodontitis
All subjects were free of systemic diseases and to be included, individuals had to be older than 18 years of age. Chronic periodontitis was diagnosed according to American Academy of Periodontology 1999 Consensus Report. |

Control Patients
Control subjects had no radiographic evidence of bone loss or any sign of past and present periodontitis. All subjects were free of systemic diseases and to be included, individuals had to be older than 18 years of age. |
