“…Injectable acrylics are available in pre-mixed cartridges, whereas in the traditional technique, the powder and liquid are mixed by hand, which can cause air bubbles to remain in the material, resulting in increased surface roughness [23]. The adhesion of C. albicans to injectable acrylic materials was found to be lower than that of conventional acrylic resins [24], which is consistent with our research results. However, Young et al reported that the adhesion of C. albicans to injectable acrylic materials was not significantly different from that of conventional and autopolymerized acrylic resins [25].…”

Aim: The aim of our study was to investigate the effect of various polishing processes applied to different types of PMMA (polymethyl methacrylate) denture base materials on the surface roughness and microbial adhesion of the base material. Methods: Sixty specimens each were prepared from heat-polymerized conventional PMMA (G), heat-polymerized injectable PMMA (E), and prepolymerized CAD/CAM PMMA (C) denture base materials. All sample surfaces were sanded with 800, 1000, 1200, and 2500 grit silicone carbide abrasives. The specimens of each denture base material were divided into three subgroups (n=20) in which different polishing methods were applied. The first group was mechanically polished (M), and the other two groups were chemically polished with light polymerized glaze liquids [Palaseal (Ps), Optiglaze Color (Og)]. A profilometer device was used to evaluate the surface roughness. Colony counting was performed to evaluate bacterial colonization after one day. The data obtained from all these measurements were evaluated using an analysis of variance, and Bonferroni corrected test was used for multiple comparisons of means (p=0.05). The interaction between surface roughness and bacterial colonization was examined by the Pearson correlation test. Regression analysis was performed to determine the relationship between them. Results: When PMMA base materials were compared, the lowest average surface roughness (Ra) values and bacterial colonization values were obtained in Group C. When polishing methods were compared, the lowest average surface roughness values were obtained in Group M. As a result of bacterial colonization measurement, lower colonization values were obtained with standardized mechanical polishing compared to other groups. Conclusion: There was no difference between the different PMMA base materials in terms of surface roughness, but there were statistical differences in bacterial colonization. The results of our study showed that mechanical polishing gave better results than light-activated glazing agents. How to cite this article: Yarar S, Değer Y, Tekin S.

“…Menurut beberapa studi yang dilakukan di universitas dan rumah sakit, 65% dari pe-makaian denture memiliki masalah yang disebabkan oleh C. albicans (yang merupakan spesies Candida paling banyak dijumpai) [4]. C. albicans dapat melakukan penetrasi pada nilon termoplastik dan tumbuh pada permukaan gigi tiruan sehingga dapat menginfeksi jaringan lunak dan merupakan penyebab terjadinya denture stomatitis [2].…”

“…Perlekatan C. albicans pada basis gigi tiruan nilon termoplastik dipengaruhi oleh beberapa faktor seperti kekasaran permukaan, sifat kimia, sifat fisik dan sifat hidrofobik dari nilon termoplastik itu sendiri [4]. Kekasaran permukaan nilon termoplastik bisa didapatkan karena sifatnya yang sukar dipulas [14].…”

“…Sudut kontak cairan pada permukaan yang cukup halus berbanding terbalik dengan tingkat pembasahan permukaan, sehingga semakin tinggi sudut kontak cairan pada permukaan menyebabkan semakin kecilnya tegangan permukaan yang terjadi [16]. Tegangan permukaan dapat memengaruhi pembasahan permukaan basis gigi tiruan oleh saliva terhadap daya adhesi mikroorganisme pada permukaan [4].…”

Background: Nylon thermoplastic (Valplast) is a flexible denture base that is used in the denture. The problem that often occurs in the use of denture namely the denture stomatitis are commonly caused by C. albicans. Denture cleanser is needed to prevent denture stomatitis by lowering the amount of C. albicans. Recently, denture cleanser from natural materials is being develope, one of them is cambodia white flower (Plumeria alba L.) extract. Cambodia white flower (Plumeria alba L.) contains bioactive compounds that are antibacterial and antifungal. Objective: To determine the effectiveness of immersion extract of cambodia white flower (Plumeria alba L.) with various concentrations as denture cleanser to amount of C. albicans in nylon thermoplastic (Valplast). Material and Methods: 25 plates nylon thermoplastic (10x10x1mm) were prepared and divided into 5 groups. The plates then contaminated with C. albicans, after that it was soaked in cambodia white flower extracts with varying concentrations for 30 minutes. The plates are subsequently placed in SDB media. Method to test the effectiveness of extract was done by looking at the SDB media turbidity with a spectrophotometer. Results and Conclusion: Cambodia white flower extract was effective in lowering the amount of C. albicans in denture base thermoplastic nylon. Cambodia white flower contained tannin, flavonoid, alkaloid and saponin which acted as antifungal that could decrease the amount of C. albicans. Keywords: Antifungal, Candida albicans, Nylon Thermoplastic and Cambodia White Flower

“…The silver-based antibacterial agent was used in denture base materials [8] to evaluate the distribution and manner of release of silver ions from the base [9,10]. Yeast of the type candida is commonly present in the plaque, their adhesion to the surface of the denture [11]. May cause candidosis infection to the patient and Surface roughness (irregularities on the surface) of the denture base material increases the likelihood of bacterial buildup and candida adherence compared to a smooth surface.…”

The development of polymer chemically produces alternative materials to polymethyl methacrylate, such as nylon, and epoxy resin, these resins are modified by thermoplastic process, and This Received The disadvantage of acrylic resin is the colonization of microorganism growth of fungi and candida adhesion. This study is designed to evaluate and compared the consequence of silver nitrate fillers reinforcement Accepted flexible acrylic hardness as one of the mechanical properties to find the effect of various concentrations. A (0.1and 0. 2) ml of the filler (silver nitrate) additive to the flexible acrylic. Forty five (45) specimens were prepared for testing in this study. The hardness test was used in this study. The sample of this test was divided into (3) groups (control group) and experimental groups as follows: Group A= (15) specimens without silver nitrate (Control group 0% silver nitrate). Group B= (15) specimens with (0.1 ml) silver nitrate. Group C= (15) specimens with (0.2 ml) silver nitrate. All control and test groups were processed; curred then finished and polished the specimens ready for testing. Shore A test against the concentration of silver nitrate the result of this study showed a high significant increase in the mean value of hardness for control groups to the silver nitrate compared with experimental groups.
