Assessment of Salivary Malondialdehyde and Superoxide Dismutase Levels in Completely Edentulous Patients: An In Vivo Study.

Introduction Residual ridge resorption (RRR) is a chronic inflammatory process; the free radicals formed may lead to tissue damage in the form of bone resorption mediating through many pathways and processes. We aimed to study the correlation between levels of malondialdehyde (MDA) and superoxide dismutase (SOD) enzyme and residual ridge resorptive status levels in completely edentulous patients. Methods This study included 45 patients aged 40-65 yrs who were completely edentulous.
