“…Although continuous use of citric acid cleansers for 3 months showed adverse effects with greater ion release from Co–Cr alloys [17,18], no harmful effects have been demonstrated with denture materials in general [19]. In contrast, other denture cleansers, mainly those containing sodium hypochlorite, could increase surface roughness, decrease hardness, and eventually change the color of acrylic resins and denture liners [19-21].…”

“…In contrast, other denture cleansers, mainly those containing sodium hypochlorite, could increase surface roughness, decrease hardness, and eventually change the color of acrylic resins and denture liners [19-21]. Therefore, citric acid cleansers might be suitable for removable dentures and orthodontic appliances and for removing biofilms and preventing their recolonization.…”

BackgroundIt is well known that the use of denture cleansers can reduce Candida albicans biofilm accumulation; however, the efficacy of citric acid denture cleansers is uncertain. In addition, the long-term efficacy of this denture cleanser is not well established, and their effect on residual biofilms is unknown. This in vitro study evaluated the efficacy of citric acid denture cleanser treatment on C. albicans biofilm recolonization on poly(methyl methacrylate) (PMMA) surface.MethodsC. albicans biofilms were developed for 72 h on PMMA resin specimens (n = 168), which were randomly assigned to 1 of 3 cleansing treatments (CTs) overnight (8 h). CTs included purified water as a control (CTC) and two experimental groups that used either a 1:5 dilution of citric acid denture cleanser (CT5) or a 1:8 dilution of citric acid denture cleanser (CT8). Residual biofilms adhering to the specimens were collected and quantified at two time points: immediately after CTs (ICT) and after cleaning and residual biofilm recolonization (RT). Residual biofilms were analyzed by quantifying the viable cells (CFU/mL), and biofilm architecture was evaluated by confocal laser scanning microscopy (CLSM) and scanning electron microscopy (SEM). Denture cleanser treatments and evaluation periods were considered study factors. Data were analyzed using two-way ANOVA and Tukey’s Honestly Significant Difference (HSD) test (α = 0.05).ResultsImmediately after treatments, citric acid denture cleansing solutions (CT5 and CT8) reduced the number of viable cells as compared with the control (p < 0.01). However, after 48 h, both CT groups (CT5 and CT8) showed biofilm recolonization (p < 0.01). Residual biofilm recolonization was also detected by CLSM and SEM analysis, which revealed a higher biomass and average biofilm thickness for the CT8 group (p < 0.01).ConclusionCitric acid denture cleansers can reduce C. albicans biofilm accumulation and cell viability. However, this CT did not prevent biofilm recolonization.

ÖZETAmaç: Protez kaide materyallerinin yüzey pürüzlülüğü protezin klinik kullanımını etkileyen önemli bir özel-liktir. Bu çalıĢmanın amacı farklı cila materyallerinin polimetilmetakrilat (PMMA) ve poliamid içerikli protez kaide maddelerinin, temizleme tableti uygulama sonrası yüzey pürüzlülüğüne etkisinin değerlendirilmesidir. Gereç ve Yöntem: ÇalıĢmada polimetilmetakrilat (QC -20) ve poliamid (Deflex) esaslı iki farklı kaide maddesi kullanılarak toplamda 60 adet örnek 3 mm kalınlık ve 20 mm çapta diskler halinde (n=10) hazırlandı. Kontrol grubunda örnekler pomza ve kıl fırça ile cilalandı. Ġkinci grup örneklere pomza ile yapılan cilayı takiben Universal Polishing Paste, üçüncü gruba ise Palaseal cila materyali uygulandı. Yüzey pürüzlülük öl-çümleri örnekler efervesan tablet formundaki Corega temizleyici solüsyon uygulamadan önce ve sonra dijital bir profilometre cihazı kullanılarak yapıldı. Örneklerin pürüzlülük değiĢiklikleri (Ra) iki yönlü varyans analizi ve Fisher's LSD test ile istatiksel olarak karĢılaĢtırıldı (p<0,05) Bulgular: Cila materyalleri ve protez kaideleri arasın-da istatiksel olarak anlamlı etkileĢimler bulundu (p< 0,001). Cila materyali uygulanan bütün örnekler, sadece pomza ile cilalanan kontrol gruplarına göre daha düĢük pürüzlülük değerleri gösterdi (p<0,001). Protez temizleyicisi polimetilmetakrilat ve poliamid rezinlerinin pürüzlülüğünü anlamlı olarak arttırdı (p<0,001) Sonuç: Protez cila materyallerinin uygulanması ile protez yüzeylerinin daha düzgün hale getirilebileceği ve protez temizleyici tabletlerin neden olabileceği yüzey pürüzlülüğünü azaltabileceği göz önünde bulundurulmalıdır. Anahtar Kelimeler: polimetilmetakrilat; poliamid; protez temizleyicileri; yüzey pürüzlülüğü ABSTRACT Aim: Surface roughness of denture base materials is an important property that affects clinical use of the prostheses. The aim of this study is to evaluate the effect of different polishing materials on surface roughness of polymethlymethacrylate and polyamide denture base resins after use of a denture cleaner. Material and Method: Total of 60 samples were prepared from polymethlymethacrylate (QC-20) and polyamide (Deflex) as 3 mm thickness and 20 mm diameter disc shaped (n=10). Samples were polished with pumice and bristle brush in control groups. Universal Polishing Paste were subjected to the second group after pumice and Palaseal were subjected to the third group. Surface roughness test was performed with a digital prophylometer (Ra) before and after effervesance denture cleaner (Corega). Data were analysed by two way ANOVA and Fischers LSD post hoc test (p<0,05). Results: Polish materials and denture bases showed significant interactions (p<0,001). Groups polished with polish materials showed significantly lower surface roughness values when compared to control groups that polished only with pumice (p<0,001). Denture cleaner increased the surface roughness of polymethlymethacrylate and polyamide resins significantly (p<0,001). Conclusion: It should be considered that denture polish materials may provid...
