Abstract

Pit and fissure are varies in shape and depth. Tooth with deep and narrow pit and fissure are susceptible for food and baterial retention that leads to caries formations, so it needs prevention treatment with more effective method such pit and fissure sealant. This study aimed to obtain information about marginal adaptation as mean value of distance between enamel surface and pit and fissure sealant by using Scanning Electron Microscope (SEM). Samples were 4 maxillary premolars with deep and narrow pit and fissure which were applied composite resin (3M ESPE Clinpro) and GIC (Fuji VII) as sealants. Specimens were stored for 24 hours and 1 month in incubator with temperature of 37C and were immersed in 5% methylene blue solution for 24 hours, then were observed under SEM. Analysis result showed mean value of distance between enamel surface and pit and fissure sealants resin based were 1.79 0.026 m after 24 hours application and 1.37 0.004 m after 1 month application while on GIC based were 33.37 1.520 m after 24 hours application and 3.6925 0.710 m after 1 month application. Conclusion of this study, there were a difference mean value of distance between enamel surface and sealants composite resin based and GIC based, where smaller distance was showed after 1 month application than 24 hours application.Keywords: pit and fissure sealants, marginal adaptation, and Scanning Electron Microscope (SEM).

Abstract

AbstractHeat cured acrylic resin is material that mostly used as a denture base. Cinnamon extract contains polyphenol which will make rough on the surface if it contact with acrylic resin. Aim of this research was to derermined the effect of cinnamon (Cinnamomum burmanii) extract concentration to surface roughness of heat cured acrylic resin. This research used 30 heat cured acrylic resin as specimens in size 20x20x2mm, 10 specimens for each concentrations of 40%, 50% and 60%. The specimens were immersed in aquades for 24 hours and tested the first surface roughness, and immersed in cinnamon extract with a concentration of 40%, 50% and 60% for 4 days. Each specimens tested the second roughness by using Surface Roughness Tester. Data was analyzed by paired t-test and one way ANOVA. Result showed a significant differences (p0,05) between the roughness before and after immersed in cinnamon extract concentrations of 40%, 50% and 60%. There was a significant differences (p0,05) between the concentration of 40% and 50% to the concentration of 60%, and no significant differences between the concentration of 40% and 50%. Concluded that the surface roughness of heat cured acrylic resin increases with increasing of cinnamon (Cinnamomum burmanii) extract concentration.Keyword: heat cured acrylic resin, cinnamon extract, surface roughness

Abstract

Alginate is one of the impression materials that is often used in Indonesian dentistry.However in some cloistered places alginate is difficult to beobtained because of distance and limited supply. Handling this situation, modification of impression material is done by adding natural ingredient that contains polysacarida such as corn flour (Zea mays). This research aims know the knowledge about corn flour (Zea mays) addition in alginate impression material as alternative impression materialreviewed fromsetting time. Twenty four specimens in this research are divided into six groups (alginate : corn flour) they areA (100%: 0%), B (55%: 45%), C (52.5%: 47.5%), D (50%: 50%), E (47.5%: 52.5 %), and F (45%: 55%). Measurement test of setting time employs an indicator of setting time cylinder bar and made of poly (methyl methacrylate). Data is statistic analyzed using ANOVA test and posh hoc tukey. Based on ANOVA statistic test shows that the presence of corn flourdifference setting time in corn flour mixed by alginate impression material among every group. However continued test result there is no significant difference among D with C and E. the conclusion of this research is corn flour (Zea mays) can be used as alternative impression material reviewed from setting time. Getting higher the corn percentage so getting long the setting time. The consistency that approaches alginate setting time is B (55% : 45%).Keywords : Alginate, Corn Flour, Setting Time
