ObjectiveTo detect activities of salivary myeloperoxidase (MPO) and concentrations of salivary tumor necrosis factor (TNF)-α as indicators of inflammatory reaction and salivary immunoglobulin E as an indicator of allergic reaction after complete insertion of acrylic dentures.Subjects And MethodsComplete dentures were made for a uniform group of elderly patients, and saliva samples were taken immediately before they were given to the patients, as well as 2, 3, 7, and 30 days after insertion of the dentures, with simultaneous monitoring of changes in the oral mucosa.ResultsAfter 7 and 30 days of wearing upper and lower complete dentures, nonsignificant increases in salivary MPO and TNF-α were proven to be indicators of inflammation. No changes were observed in the values of salivary immunoglobulin E during a 30-day observational period, which excluded the appearance of allergic reactions to acrylic materials in the tested group of patients.ConclusionA nonsignificant increase in the levels of MPO was observed on day 7; it decreased after 30 days. TNF-α also tended to increase in a nonsignificant manner.© 2019 The Author(s) Published by S. Karger AG, Basel.
