The aim of this study is to investigate the bacterial loads present on essix retainers in patients' contention therapy. Patients are randomly divided into three groups, depending on the product used for the cleansing of the retainers: Geldis, Polident tablets and water. Microbiological samples were taken from the retainers at the baseline, after 1 and after 2 months, together with Bleeding Index, Plaque Index, BEWE Index and Schiff Air Sensitivity test.
