mRNA expression levels of IFNG in the healthy gingival biopsies, experimental gingivitis and chronic periodontitis samples. Fold induction is shown using 18S as an internal housekeeping gene. As compared with gingival biopsies with periodontal health, a 1.96-fold increase in the transcriptional level of IFNG is significantly higher (p =0.04) in the chronic periodontitis biopsies, which was indicated by “*”. In contrast, the transcriptional level of IFNG in experimental gingivitis showed an 8.5-fold increase and was significantly higher (p =0.01) than tissues with peridontal health, which was indicated by “**”.
