This study examined the association between tumour necrosis factor-alpha ( α (-308 G/A) polymorphism and gingivitis, and serum and salivary TNF- α levels, in a Mexican population. This study enrolled 171 subjects, divided into two groups healthy subjects and gingivitis patients. α (-308 G/A) gene polymorphism was analyzed by PCR-RFLP assay. Salivary and serum samples were used to measure cytokine levels through the ELISA technique. α (-308 G/A) polymorphism was shown to have a protective effect in carriers of the A/A genotype and alle
