Journal ArticleDOI

Effects of mechanical and chemical methods on denture biofilm accumulation

TL;DR: It can be concluded that brushing alone was more effective than the chemical method employed, and the best results were obtained by a combination of methods.
Journal ArticleDOI

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

TL;DR: Although the color changes after the immersion in denture cleansers were clinically insignificant, the Corega Tabs group showed higher color differences and the Bony Plus group showed significantly increased surface roughness.
Journal ArticleDOI

Effect of three methods for cleaning dentures on biofilms formed in vitro on acrylic resin.

TL;DR: The three denture hygiene methods showed different effects depending on the type of microbial biofilms formed on acrylic base resin specimens, including chemical, mechanical, and combination methods.
Journal ArticleDOI

Behaviors and hygiene habits of complete denture wearers

TL;DR: It was concluded that the patients interviewed had limited knowledge about prosthetic hygiene and oral care, the method more used by patients was the mechanical method of brushing, most patients used the same complete dentures for more than 5 years and slept with the dentures.
Journal ArticleDOI

Color Stability, Surface Roughness and Flexural Strength of an Acrylic Resin Submitted to Simulated Overnight Immersion in Denture Cleansers

TL;DR: Overnight immersion in denture cleansing solutions simulating a year and a half of use did not alter the flexural strength of acrylic resin but caused noticeable color alterations, higher for alkaline peroxide.
