tetrapod like nano particle zno Acrylic Resin composite and its multi function property
Progress in Organic Coatings, 2003Co-Authors: T XuAbstract:Tetrapod-like nano-particle ZnO/Acrylic Resin composite was prepared by a direct dispersing method forming a multi-function coating. The composite with uniform distribution of nano-ZnO in the Acrylic Resin have both anti-electrostatic and antibacterial functions. The coatings can be used for plastic materials or others. The mechanisms of the electrostatic and antibacterial functions were also analyzed.

Biocompatibility of Acrylic Resin after being soaked in sodium hypochlorite
Dental Journal: Majalah Kedokteran Gigi, 2009Co-Authors: Nike HendrijatiniAbstract:Background: Acrylic Resin as basic material for denture will stay on oral mucosa for a very long time. The polymerization of Acrylic Resin can be performed by conventional method and microwave, both produce different residual monomer at different toxicity. Acrylic Resin can absorb solution, porous and possibly absorb disinfectantt as well, that may have toxic reaction with the tissue. Sodium Hypochlorite as removable denture disinfectant can be expected to be biocompatible to human body. The problem is how biocompatible Acrylic Resin which has been processed by conventional method and microwave method after being soaked in sodium hypochlorite solution. Purpose: The aim of this study was to understand in vitro biocompatibility of Acrylic Resin which has polimerated by conventional method and microwave after being soaked in sodium hypochlorite using tissue culture. Methods: Four groups of Acrylic Resin plate were produced, the first group was Acrylic Resin plate with microwave polymeration and soaked in sodium hypochlorite, the second group was Acrylic Resin plate with microwave polymeration but not soaked, the thirdwas one with conventional method and soaked and the last group was one with conventional method but not soaked, and in 1 control group. Each group consists of 7 plates. Biocompatibility test was performed in-vitro on each material using fibroblast tissue culture (BHK-21 cell-line). Result: The percentage between living cells and dead cells from materials which was given Acrylic plate was wounted. The data was analyzed statistically with T test. Conclusion: The average value of living cells is higher in Acrylic Resin poimerization using microwave method compared to conventional method, in both soaked and non soaked (by sodium hypochlorite) group. This means that sodium hypochlorite 0.5% was biocompatible to the mouth mucosa as removable denture disinfectant for 10 minutes soaking and washing afterwards.

Shear bond strengths for composite and autopolymerized Acrylic Resins bonded to Acrylic Resin denture teeth.
Journal of Prosthetic Dentistry, 1999Co-Authors: Efstratios Papazoglou, Athanasios I. VasilasAbstract:Abstract Statement of problem. Composite has been used to modify Acrylic Resin denture teeth. Purpose. This in vitro investigation examined the shear bond strengths between composite and autopolymerized Acrylic Resin bonded to Acrylic Resin denture teeth. Material and methods. The surface treatments used for the denture teeth included wetting with methyl methacrylate (MMA), vinylethyl methacrylate monomer (VEMA), unfilled liquid Resin, composite bonding agent, and composite color modifier. Nonhydrated and hydrated denture tooth groups were included. A commercial composite was bonded to the denture teeth. The control group consisted of autopolymerized PMMA Resin bonded to the Acrylic Resin denture teeth, and another group consisted of polyvinylethyl methacrylate bonded to Acrylic Resin denture teeth. The samples were thermocycled and tested in shear. Results. Acrylic Resin denture teeth prewetted with MMA and treated with unfilled Resin or a bonding agent had bond strength values comparable to the control group. VEMA was not as effective in promoting the bond. Composite color modifier did not produce a significantly weaker bond between the Acrylic Resin teeth and added composite. No prewetting of the teeth with MMA resulted in the lowest bond strength. Mean shear bond strengths for corresponding hydrated and non-hydrated groups were not significantly different. Conclusion. Bond strength of composite-to-Acrylic Resin denture teeth was comparable to the bond strength of autopolymerized Acrylic Resin. (J Prosthet Dent 1999;82:573-8.)

Candida albicans adherence on Acrylic Resin plates immersed in black tea steeping Candida albicans adherence on Acrylic Resin plates immersed in black tea steeping
2020Co-Authors: Daftar PustakaAbstract:Background: Black tea or Cournelia sinensis is one of known tea varieties in Indonesia. Actually, black tea is consumed daily as beverage that can function as antiseptics and fungicides. Black tea containing antibacterial and fungicide properties can reduce the number of Candida albicans (C. albicans) colony attachment on the surface of Acrylic Resin plates. Purpose: This study was done to determine the effective concentration of black tea steeping used as the immersion material of Acrylic Resin plates towards the number of Candida albicans colonies. Methods: In this study, Acrylic Resin plates with the size of 10 × 20 × 1 mm were immersed in black tea steeping with the following concentrations, 3.33%, 6.66%, and 13.33%, for one hour. The growth of C. albicans colonies were then detected by counting the number of colonies growing on Sabouraud’s dextrose medium. Data was analyzed by using both One-Way ANOVA with the significance level of 5%, and Tuckey’s multiple comparison tests (Tuckey’s HSD test). Results: There were significant differences in the number of C. albicans colonies in Acrylic Resin plates immersed in black tea with the concentration of 3.33%, 6.66%, and 13.33%. Conclusion: It can be concluded that the higher concentration of black tea (13.33%) used to immerse Acrylic Resin plates, the greater the decreased number of C. albicans colonies.
