Efficacy of newly developed denture cleaning device on physical properties of denture material and Candida biofilm

Abstract

Background/purposeElectrolyzed water has antimicrobial activity against oral microbes. The purpose of this study was to investigate the effects of a denture cleaning device that uses electrolyzed water on Candida biofilm on denture base-material and the physical properties of the denture material.Materials and methodsDenture base-resin disks were prepared with Polymethyl methacrylate. After the formation of Candida albicans biofilm on the resin disks, the antimicrobial activity of the denture cleaning device and the chemical cleanser against C. albicans biofilm was compared. The resin disks were also treated with the cleaning device and the chemical cleanser for 150 days, and the physical properties were analyzed by an atomic force microscope, Vickers hardness tester, and colorimeter.ResultsThe denture cleaning device and the chemical cleanser reduced the levels of C. albicans biofilm on the denture resin. Upon immersing of the resin disks for 150 days, the electrolyzed water of the denture cleaning device did not significantly change the surface roughness of the specimens, but significantly reduced its Vickers hardness compared to the initial value. The color changes of the resin disk were 0.477 ± 0.076, 0.612 ± 0.095 and 0.562 ± 0.096 after treating with tap water, the chemical cleanser, and the denture cleaning device, respectively.ConclusionThe denture cleaning device may be suitable for use by the elderly to clean dentures without side effects caused by the misuse of chemical cleanser.

Pengaruh Perendaman Ekstrak Bunga Sepatu (Hibiscus rosa sinensis L.) terhadap Pertumbuhan Candida albicans pada Plat Resin Akrilik

“…Pembuatan gigi tiruan mempunyai tujuan untuk memperbaiki estetika penampilan dan kenyamanan, mengembalikan fungsi mastikasi dan fonetik, serta melindungi jaringan pendukung yang berada di bawah gigi tiruan. 3,4 Salah satu komponen gigi tiruan yaitu plat basis. 5,6 Bahan dari plat basis gigi tiruan yang sering dipakai saat ini yaitu resin akrilik.…”

Electrolysis Study Effect on Electrolyzed Water as Disinfectant and Sanitizer

“…After soaking fruit in an EW water solution for as little as 10 minutes, fruit rot caused by the fungus Botryosphaeria berengeriana was suppressed in pears [17]. EW contains antifungal properties and can lower Candida albicans biofilm levels on denture resins: a denture storage and disinfection device [18]. EW has lately been recommended as the disinfectant of choice in an oral and maxillofacial surgery office [19] based on a recent study.…”

Electrolyzed Water Generated On-Site as a Promising Disinfectant in the Dental Office During the COVID-19 Pandemic

“…It significantly reduced five major periodontal pathogens when used as a mouthwash and for toothbrush disinfection, even when EW was produced via electrolysis of drinking water, without adding salt (11). EW also has antifungal activity and can reduce the levels of Candida albicans biofilm on denture resins; a denture storage and disinfection device based on EW was recently developed (12). Furthermore, running EW through dental unit waterlines, even for a short period, was found to be effective in minimizing microbial biofilm contamination in the waterlines; and its use reduced the count of viable bacteria to negligible levels in coolant water spray from handpieces and three-way syringes, thus ensuring output water of good microbiological quality (13,14).…”
