Effect of denture cleansers on physical properties of heat-polymerized acrylic resin

Abstract

Although the color changes after the immersion in denture cleansers were clinically insignificant, the Corega Tabs group showed higher color differences. The Bony Plus group showed significantly increased surface roughness. Both effervescent tablets Corega Tabs and Bony Plus significantly diminished the flexural strength of the acrylic resin.

Comparative effects of denture cleansers on physical properties of polyamide and polymethyl methacrylate base polymers

“…The result of this study is consistent from those of Ünlü et al 19) and Peracini et al 1) , who also detected a significant whitening effect on heat polymerized acrylic resins with perborate cleansing agents. However, Sato et al 30) did not detect color changes in the PMMA based acrylic resins with the use of three different denture cleansers.…”

“…Peracini et al 1) immersed acrylic resin samples in alkaline peroxide solution for 6 days and reported that surface roughness of the resins were increased. This finding is consistent with the results of our study.…”

“…In patients who use fixed and partial removable dentures, hygiene of dentures and maintaining the health of oral mucosa are of great importance 1,2) . Denture cleansers are used to provide adequate denture plaque control, prevent halitosis, remove discoloring caused by foods and drinks, eliminate Candida albicans and Candida glabrata and other microorganisms, to dissolve calculus and prevent denture-induced stomatitis [3][4][5] .…”

Effect of cleanser solutions on the color of acrylic resins associated with titanium and nickel-chromium alloys

“…However, there have been reports of titanium alloy tarnishing (surface discoloration) 12 and corrosion (surface pitting). 13 Previous studies have evaluated color alterations in acrylic resins treated with 0.5% and 1% hypochlorite alkaline solutions, 7,14,15,16 as well as with alkaline peroxide solutions, 7,17,18 and they have revealed that the type of sanitizer, the immersion time, and the period of use are factors to be considered. In relation to the metal surface, it was determined that tarnish and spot corrosion on Co-Cr alloys are deleterious effects of immersion in cleansing solutions.…”
