Abstract

The aims of this study were to quantify and identify bacteria in the in-use acrylic resin maxillary obturator-prostheses. Aspiration pneumonia-associated or airborne bacteria such as Klebsiella and Pseudomonas species as well as oral bacteria were detected at 5.0 × 10-2.5 × 106 colony forming units (CFU)/mL. This study revealed that several species of viable bacteria are present within the obturators. It is suggested that the inner space of obturator can act as bacterial reservoirs.
