The Difference

The rough surface of a heat cured acrylic resin as a denture base can cause a pathogenic buildup of plaques and biofilms, so an effort to clean the denture base is needed. The available denture cleaning chemicals are proof of some disadvantages, so it is necessary to do research on alternative natural ingredients. Srikaya seed extract using ethanol 96% solvent has been shown to have antibacterial activity and with its various properties, so that it has the potential to become denture cleaning agents. Samples were made based on ADA No.17 specifications with 5 samples in each of the 6 treatment groups, sampling using Simple Random Sampling. Samples contaminated with S. mutans were soaked in srikaya seed extract 25%, 50%, 75%, 100%, 0.5% NaOCl and sterile aquadest. There was a significant difference (p <0.05) in each treatment group. There is an influence of the difference in concentration of srikaya seed extract on the growth of S. mutans bacteria on a heat cured acrylic base. Keywords: heat cured acrylic resin, S.mutans, srikaya seed extract, absorbance

Abstract This study aimed to reveal the difference of the basic ability of scientific work development between students who are teached using discovery learning and conventional learning. This study used quasy experiment with The Non Equivalent Pretest-Posttest Design. The subyek which are 58 VIII grade students in one of junior high school in Palu City are chosen with simple random sampling. Data were collected by observation sheets (check list) and were analyzed by normality, homogenity, and t-test using IBM SPSS Statistic 22 program. The result shows that the significance of Sig (2-tailed) is 0.00 < 0.005, which means that H0 is rejected and H1 was accepted. In addition, the data of the basic ability of scientific work development showed that the value for students teached by the discovery learning model is 58.28% and students teached by the conventional learning model is 47.13%, so it can be concluded that there is a significant difference on the basic ability of scientific work development between students who are teached using discovery learning and conventional learning in the material of sight and optical devices.

The heat cured acrylic resin is common used as denture base material, but its microporosity can affect the cleanliness of the denture base lead to accumulation of plaque and food waste, and further increase the number of Candida albicans and cause denture stomatitis. There are 2 type of cleaning agents; natural cleaning agents, such as basil and chemical cleaning agents, for example effervescent artificial cleaning tablets. This study compared the effectiveness of basil leaves squeeze and effervescent denture cleaning solutions in soaking heat cured acrylic resin plates on the growth of C. albicans. There were 24 of 10x10x1 mm acrylic resin plates divided into 6 treatment groups. The acrylic resin plate was soaked in the basil leaves squeeze and effervescent denture cleaning solutions. Measurement of C. albicans absorbance used a spectrophotometer, then calculated the total of C. albicans using the formula. Data was analyzed using the One Way ANOVA test. The analysis showed that there are significant differences on the growth inhibition of C. albicans between treatment groups (p <0.005). The effervescent denture cleansing solution has a better antifungal effectiveness than the basil leaves

Denture base widely were made from heat polymerized acrylic resin. Either one of physical properties on this material must be concern is surface roughness, rough surface could interfere patient’s comfort, and microbial colonization. Therefore polishing procedure were needed, polishing material that mostly used on acrylic resin was pumice, there is another alternative material i.e eggshell and toothpaste because had abrasive ability. The aim of this research is to determine the difference surface roughness of heat polymerized acrylic denture base resin used pumice, eggshell and toothpaste as polishing materials. The design research in this study is laboratory experimental with rectangle sample with size 50 x 20 x 3 ±1 mm. There are 30 samples for 3 groups. The result of this research shows a significant difference between pumice group and eggshell group with p value = 0,0001 (p < 0,05), pumice and toothpaste with p value = 0,0001 (p < 0,05), egghsell and toothpaste with p value = 0,032 (p < 0,05). Polishing that used an alternative material from eggshell and toothpaste produce lower surface roughness score rather than pumice.

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, the 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 Background: Chemical trauma to the cornea is an emergency condition of the eye that requires early diagnosis and good treatment. Alkaline have ability to saponify fatty acids in cells and cell membranes which can make penetration into the stroma and destroy proteoglycans and collagen in cells. Aloe vera (AV) contains several active substances that are reported to have anti-inflammatory, immunomodulatory, and wound healing effects. AV has been reported to accelerate the healing process of corneal epithelial defects by increasing fibroblast proliferation, collagen production and growth factor production. This study aims to determine the difference between the effect of aloe vera extract with a concentration of 10%, 20%, 40% and BSS on the healing of extensive corneal lesions in white wistar rats alkaline trauma models. Method: This study was an experimental study with a pre and posttest only with control group design in vivo approach to 30 Wistar white rats which were divided into 5 treatment groups for 3 days. Comparative analysis of effectiveness using the ANNOVA test or the Kruskal Wallis test and continued by the post hoc test. Results: Based on the one way ANOVA test there was a statistically significant difference in effectiveness between the five treatment groups on the percentage of corneal wound healing area and TGF-β expression with an assessment of p = 0,000 each. The administration of alloevera (AV) concentration of 20% had a significant difference in percentage of healing of corneal lesions and TGF-β expression compared with other treatment groups with p = 0,000 each. Large differences in the area of corneal lesions in the 40% AV group were -0.45 in the BBS group, 0.146 in the 10% AV group, 0.493 in the 20% AV group. The difference in the AV group 10% was 0.30 in the BBS group, -064 in the AV group 20%, and -0.14 in the AV group 40%. However, TGFβ expression in the normal control group that did not receive treatment was 54.94 (53.21-56-12). TGFβ levels in the BSS group were 10.44, the 10% aloe vera group was 25.43, 47.99 for the 20% aloe vera group and 37.95 for the 40% aloe vera group. Conclusion: There is a difference between the effect of aloe vera extract with concentrations of 10%, 20%, 40% and BSS on the extensive healing of corneal lesions in white wistar rats with alkaline chemical trauma models.
