Research Abstract

Few studies have examined the bacterial invasion in the acrylic resin prostheses. The aim of this study is to quantify and identify the microorganisms in the acrylic resin denture bases and in the inner space of acrylic resin obturator of dento-maxillary prostheses after long-term use. Several species of viable bacteria were detected in acrylic resin denture bases and obturators. The findings of this study suggest that acrylic resin prostheses and bacteria inside the acrylic resin prostheses may be associated with oral malodor and oral/respiratory infections in individuals wearing prostheses.
