Abstract

Background: Acrylic resin was a material of denture base which frequently used, but it still had a weakness that it was porous, then, it was often the breeding ground of Candida albicans. Virgin coconut oil (VCO) contained fatty acid which was effective to hamper the growth of C.albicans. Objective: This research was to identify the effect of VCO on the growth of C.albicans on acrylic resin denture. Methods: This research was an experimental laboratory research which exerted post-test control group design. The total sample 24 which were divided into 3 groups of treatment and 1 group of control. The treatment covered acrylic plates soaking which have been contaminated with C.albicans suspension into VCO in concentration level 25%, 50%, 75%, and sterile aquades for 8 hours. The acrylic plate was vibrated to knock out C.albicans and was then continued by colony counting on the media of Sabouraud Dextrose Agar (SDA). The statistic test employed Kruskal-Wallis and continued to the Post-Hoc test which employed Mann-Whitney. Findings: The VCO in concentration level 25%, 50%, and 75% affected to inhibit the growth of C.albicans. In the Kruskal-Wallis test, it was found a significant difference between the number of C.albicans on the control group and the VCO in concentration level 25%, 50%, and 75% (p<0,05). The Post-Hoc Mann-Whitney test indicated no significant difference between VCO in concentration level 25% and 50%, 25% and 75%, also 50% and 75% (p>0,05). Conclusion: The VCO in concentration level 25%, 50%, and 75% affected was able to hamper the growth of C.albicans. Further, there was no significant difference in each VCO concentration.

Abstract

Background: The color of teeth in each individual varies greatly in which it is influenced by the color of dentin and enamel. The most frequent tooth discoloration that happened is caused by extrinsic stains like coffee. Coffee consumption habits are increasing along with the level of creativity in serving coffee. Nowadays, coffee with conventional methods like black/Turkish coffee and manual brewing methods such as drip brewing and espresso become popular coffee that are fancied by Indonesian people. Exposure to chromogenic substances and the acidic nature of coffee can cause the formation of pores in enamel and facilitate the deposition of dyes, which cause the color changes. Aim: The aim of this research was to analyze the effect of brewing methods on tooth discoloration. Method: This research was a true experimental study with a pre-post test control group design. Twenty eight post-extracted first premolar teeth samples divided into 4 groups for drip, espresso, black coffee and control by implementing random allocation. All samples were immersed in each coffee brewing group for 3 hours, 6 hours, and 9 hours. The teeth color was measured using a Chromameter based on the CIE L*a*b system. Statistical tests used Kruskal Wallis and Mann-Whitney test. Result: The Kruskal Wallis test showed differences in the color change ∆a * between the four groups (p < 0.05). Mann-Whitney test indicated a significant difference between the treatment group (drip, espresso, and black coffee group) and the control group (p < 0.05). Conclusion: Drip coffee, espresso and black coffee brewing methods can affect tooth discoloration, especially affects the red discoloration. But there is no difference in the effect of the drip, espresso, and black coffee brewing methods on tooth discoloration.

Abstract

ABSTRACT Background: Composite resin is the most commonly used restorative material. One of properties composite resins is surface hardness can change due to exposure of the restorative material to oral fluids such as alcoholic mouthwash. The degradation that occurs due to alcoholic mouthwash is able to reduce the surface hardness of the nanohybrid composite resin. Glycerin is able to increase the hardness of the composite resin by perfecting the polymerization that occurs in the restorative material when exposed to light cured light. Objectives: This study aims to determine the effect of glycerin application on the hardness of nanohybrid composite resins after immersion in alcoholic mouthwash. Methods: A total of 32 samples of nanohobride composite resin in this study were made in the form of a cylinder with a diameter of 5 mm and a thickness of 2 mm. The nanohybrid composite resin samples were divided into control and treatment group by applying glycerin on the sample surface before light curing. The study was continued by immersing the sample into artificial saliva for 24 hours and alcoholic mouthwash for 6 hours. The research continued with surface hardness test using the Vickers Hardness Tester. Result : Paired bivariate T test showed a significant difference between the two groups (p<0.005). The conclusions of this study indicate that the application of glycerin has an effect on the hardness of the nanohybrid composite resin after immersion with alcoholic mouthwash. Conclusion: The application of glycerin affects the hardness of the nanohybrid composite resin after immersion with alcoholic mouthwash.  Key words: Glycerin application, Hardness, Nanohybrid composite resin

Abstract

ABSTRACTBackground: Composite resin is the most commonly used restorative material. One type of composite resin based on the filler material is a nanohybrid composite resin which has the advantage of good strength and smooth surface to produce good improvements in terms of durability and aesthetics. The roughness of the resin can be affected by drinks with low pHs, such as isotonic drink. Glycerin can reduce the roughness of the composite resin by acting as a barrier so that an oxygen inhibition layer (OIL) is not formed. Purpose: This study is to determine the effect of glycerin application on the roughness of nanohybrid composite resin immersed in an isotonic drink. Method: A total of 32 samples of nanohybrid composite resin used in this study were made with a diameter of 5 mm and a thickness of 2 mm. The nanohybrid composite resin samples were divided into group I without glycerin application and group II with glycerin application before the light curing process. Both groups were then immersed in an isotonic drink for 18 hours in an incubator. The research continued with roughness testing using a surface roughness tester. Result: There was a significant difference in the roughness of the nanohybrid composite resin immersed in an isotonic drink with and without glycerin application. This is indicated by the p-value < 0.05 in the unpaired bivariate t-test, which means that there is a significant difference in the two sample groups.  Conclusion: The application of glycerin can reduce the roughness of the nanohybrid composite resin immersed in isotonic drink. Keywords: Glycerin application, Nanohybrid composite resin, Roughness.
