Effect of Protective Coating on Surface Properties

Now online in the Journal of Prosthodontics, Drs. Mohammed Ali AlBin‐Ameer, Mahdi Y Alsrheed, Ibrahim A Aldukhi, Asif Matin, Soban Q Khan, Reem Abualsaud, and Mohammed M Gad evaluate the effect of protective coatings on the surface roughness, contact angle, and Candida albicans (C. albicans) adhesion to polymethyl methacrylate (PMMA) denture base materials.

Denture bases are commonly fabricated from PMMA because it is affordable, easy to produce and repair, esthetically pleasing, and light-weight. However, one of the main disadvantages of this material is its poor surface properties which enhance microbial adhesion.

In this study, the authors tested five coating materials: nano-coat, Optiglaze, nano-silica, and cyanoacrylate. Nano-coat and Optiglaze were tested for the first time as denture coating materials and both decreased C. albicans adhesion. This is a promising result because both are readily available and easy to apply.

Nano-silica was found to be the best coating agent where its application showed the lowest contact angle. Contrary to the results of a previous study, the authors found that cyanoacrylate adhesive increased C. albicans adhesion. Future studies should investigate the durability of these coatings, particularly the effects on surface roughness and hardness after aging procedures.
