Abstract

Introduction: The denture base is the part of the removable denture that is supported by good adaptation to the underlying oral tissue. Most of the denture bases are made of acrylic or polymethyl methacrylate resin, better known as PMMA. However, acrylic resin also has disadvantages such as easily broken and absorbs liquids both water and chemicals. The chemical absorption like alcohol, ethanol, and some drinks that contain acidic materials will chemically be induced with acrylic resin and settle in the pores of the acrylic resin. The chemical damage or defect creates roughness on the surface of the acrylic resin which can cause cracking or crazing and a decrease in surface strength and hardness. Materials and Methods: The method used in this research was a laboratory experimental design with a post-test-only control group using 12 samples consisting of 2 different types of samples by measuring the surface roughness of the acrylic resin after immersing the sample with a predetermined time. Results and Discussions: One-way ANOVA test results showed a significant difference in surface roughness after the samples immersion with a value of p = 0.006 (p <0.05). Conclusions: Based on this research, can be concluded that there is an increase in the surface roughness of the heated polymerized acrylic resin for 3 hours and 4 hours of immersion. The longer the heated polymerized acrylic resin is soaked in arak hence the level of surface roughness increases.

Abstract

The color of acrylic resin plate is one of particular concern, because it's related with aesthetics of oral tissue. An acrylic resin can absorb colored fluids and cause a color change, which reduces the aesthetic value of the denture. This study aims to determine discoloration of acrylic resin plate heat cured after submersion of rosella flower extract. This study used 25 samples, divided into 5 samples for 20% rosella flower extract, 5 samples for 40% rosella flower extract, 5 samples for 60% rosella flower extract, 5 samples negative control (aquades) and 5 samples positive control (fifftydent). Soaking time is 10 minutes per day for a week. The type of research used was experimental pretest-posttest with control group design. Measurements using Adobe Photoshop and the CIELab color measurement system. Furthermore, statistically using the Shapiro wilk test, Leven's test, One Way Anova and Least Significant Diffence. The results of the study are shows the mean color change of CIELab (DE) in the five groups after treatment significantly different (p <0.05). Least Significant Difference - test (LSD) test shows the results of immersion test on extract 20% and 40% are not different from negative controls, extract 60% is different from negative controls, extract 60% is same like positive control. The conclusions in this study are concentration of immersion with rosella flower (Hibiscus sabdariffa L.) extract 20% and 40% can't change the color of the acrylic resin plate heat cured, however extract rosella flowers (Hibiscus sabdariffa L.) 60% can change the color of acrylic resin plate heat cured.

Abstract

Acrylic resin denture base are recently used as material for removable denture base, as well as thermoplastic nylon denture base that have flexibility and good esthetic. Both of these materials have porosity where food debris can attach and forming plaques. Plaque is the main habitat of oral microorganisms. One of the most frequent oral bacteria is Streptococcus mutans. Plaque and microorganism on denture could make an inflammation on soft tissue underneath the denture called denture stomatitis.The aim of this study was to understand the amount of Streptococcus mutans on thermoplastic nylon and heat cured acrylic resin removable denture base plate with 24 hours and 48 hours contact time.This study used 6 thermoplastic nylon plate and 6 heat cured acrylic resin square shaped with 10x10x1 mm size, and heat cured acrylic resin as control. Plates were soaked on tubes with Streptococcus mutans suspension at 24 hours and 48 hours contact time then all the objects were count. This study was an experimental laboratories and the method was randomized post-test only control group design federer. One Way Anova was used as the data analysis.The result shows statistically different of Streptococcus mutans amount on thermoplastic nylon and heat cured acrylic resin removable denture base plate with 24 hours and 48 hours contact time (p<0.05). Porosity of denture base may lead accumulation of Streptococcus mutans and contact time predispose bacterial growth. It is concluded that Streptococcus mutans amount on thermoplastic nylon removable denture base plate is less than heat cured acrylic resin and it is increase along with the contact time.

Abstract

Accumulation of plaque and food scraps on an acrylic resin base will increase bacterial colonies and C. albicans which will cause denture stomatitis. Maintenance of denture hygiene using mechanical, chemical and combination of two methods. Basil leaf extract contain essential oils which are important in fight against resistant C. albicans biofilms. The purpose of this study was to determine the comparison of C. albicans colonies after cleaning various denture cleaning methods. The method of this study is used an experimental method, the study design is posttest only with control group design. Sample size of heat-cured acrylic resin plate is 40x12x3mm. this study use Kruskall-Wallis test and Mann-Whitney test as data analysis for comparison tests between groups (non-parametric test). The results showed that there were significant differences between the various cleansing methods used in reducing C. albicans colonies. The compotition of flavonoids basil leaf extract is anti-microbial which can prevent the entry of fungi that harm the body.

Abstract

Dental material that is often used in dentistry is alginate. Alginate molding material has imbibition properties that absorb water when it comes into contact with water so that the shape is easier to expand and syneresis is the loss of water content through evaporation, causing shrinkage of the alginate mold when left too long in the open air. It is recommended that the printed product be disinfected first to avoid cross infection. One of the herbs that has antibacterial properties is noni. The purpose of this study was to determine differences in immersion and spraying techniques with 0.5% sodium hypochlorite and noni extract 50%, 25% and 12% for 5 minutes. Data were analyzed by ANOVA test. The conclusion of this study is that there is a change in the stability of the dimensions of the alginate mold in the AB (anteroposterior) and BC distance inter junction techniques, at concentrations of 12% and 25%, experiencing a higher increase compared to the concentration of 50% but still within the clinical tolerance limit ie below 0.5%. The spraying technique has a smaller percentage change compared to the immersion technique. There is a change in dimensional stability of alginate molds with a significant difference in the immersion and spraying technique, soaking causes an increase indimensional changes compared to the spraying technique.
