Is oxidative stress involved in the hepatic inflammatory response to apical periodontitis? A comparative study in normal and hyperlipidaemic rat

Apical periodontitis could activate systemic and liver inflammation by promoting serum IL-18, 1L-1β, TOS and OSI expression, enhancing hepatic TOS and OSI expression and inhibiting serum TOAC expression. AP under hyperlipidaemia led to more profound periapical bone destruction in the maxilla and elicit systemic and liver inflammatory responses through elevating serum levels of IL-1β, descending serum IL-4 level and improving hepatic IL-6 and TGF-β1 expression.
