RECENT PUBLICATION: In situ evaluation of the microbial adhesion on a hard acrylic resin and a soft liner used in removable prostheses

INEB researchers recently published an article in the International journal of prosthodontics, 28(1): 65-71, 2015, already available. The article is entitled "In situ evaluation of the microbial adhesion on a hard acrylic resin and a soft liner used in removable prostheses." and is authored by Gomes, A.S., B. Sampaio-Maia, M. Vasconcelos, P.A. Fonesca, and H. Figueiral.

The purpose of this study was to evaluate, in situ, the initial adhesion of microorganisms to as well as the surface roughness and chemical composition of ProBase Hot (Ivoclar Vivadent), a hard acrylic resin, and Vertex Soft (Vertex-Dental), an acrylic-based soft liner, used in removable dental prostheses. The Vertex Soft liner has been found to be more susceptible to microbial adhesion than the acrylic resin ProBase Hot, probably due to its greater surface roughness. The application of Vertex Soft liner to a hard denture base may lead to a higher risk of oral and systemic infections for patients, highlighting a greater need for plaque control, especially for more susceptible individuals.
