Abstract

Background: Dental caries is a hard tissue disease caused by bacterial metabolic activity that causes demineralization, teeth that have caries should be filled in order to function again. One of the restorative materials closer to natural teeth is composite resin because it is the same colour as natural teeth and is easy to shape. As for the placement technique, bulkfill is also used because it is more time-efficient, and irradiation is accompanied by applying the restoration material in one batch. However, the bulkfill technique often causes micro-leakage of dental caries deposition. The intermediate layer is an intermediate layer used to prevent micro-leakage at the edges of the restoration as a base layer for restoration to create a good adaptation before applying packable composite resin. Therefore, bulkfill coating technique with the intermediate layer can reduce the risk of microleakage. Purpose: To describe the bulkfill technique with an intermediate layer against marginal adaptation with class II composite resin restorations. Review: The literature sources used in the preparation of the articles through several databases with descriptions. More journals say that micro-leakage in class II cavity deposition with the intermediate layer technique is better than the bulkfill technique because the intermediate layer technique has better bond strength than the bulkfill technique. If the Bulkfill technique is modified with the Intermediate layer technique, it can show good correlation and internal adaptation. Conclusion: Bulkfill technique with an intermediate layer against marginal adaptation with class II composite resin restorations can reduce the microleakage rate by reducing the polymerization's shrinkage strain.

Abstract

Background: Pulp inflammation can be treated with pulp capping by calcium hydroxide as the gold standard. Pulp capping by calcium hydroxide could causing tissue necrosis followed by inflammation. Calcium hydroxide combined with propolis which have anti-inflammatory effects through inhibition of the Nf-kB pathway and pro-inflammatory cytokines. That process will inhibit the increase of vascular permeability and neutrophil chemotaxis. Inflammatory process can accelerate by controlling the amount of neutrophil cells as a acute phase marker, so the healing process occurs more quickly. Therefore it is necessary to study the amount of neutrophil cells in the pulp perforation of Wistar rats after applicated by combination of calcium hydroxide-propolis. Purpose: To analyze the difference amount of neutrophil cells on the Wistar rats pulp perforation after applicated by calcium hydroxide-propolis combination compared with calcium hydroxide-aquadest Method: M1 tooth perforated for all groups with three types tratment: no medication (control group), calcium hydroxide-aquadest 1: 1 (P-1 group), and calcium hydroxide-propolis 1: 1.5 (P-2 group) and closed with cention. Observations were made on the 1st, and 3rd day with HE staining. Results: One Way ANOVA shown a significant difference (p <0.05) of the average amount of neutrophil cells between all treatment groups on 1st day (p=0,000) and 3rd day (p=0,000). The amount of neutrophil cells in the calcium hydroxide-propolis (P-2) combination group was lower than control group and calcium hydroxide-aquadest (P-1) group on the 1st and 3rd day. Conclusion: The amount of neutrophil cells after application of calcium hydroxide-propolis is lower than calcium hydroxide-aquadest application.

Abstract

Background: Inflammation of the pulp can lead to elicit pain. Pain in inflammation is induced by the cyclooxygenase-2 enzyme (COX-2) which induces prostaglandin E2 (PGE2) resulting in pain. Pain in the pulp can be relieved by eugenol. In its application, eugenol is toxic to pulp fibroblasts. Due to the side effect, it is worth considering other biocompatible materials with minimal side effects, such as propolis. Flavonoids and phenolic acids that contained in propolis can inhibit COX-2. Therefore, an analysis outlined in the literature review is needed to examine the results of research related to the role of propolis as pulp pain relief by inhibiting COX-2 expression. Purpose: To analyze the role of propolis in pulp pain by inhibiting COX-2 expression. Reviews: Propolis extract that extracted by ethanol, water, and hydroalcohol has pain relief properties in the pulp by inhibiting COX-2 by directly binding to the COX-2 receptors and by reducing the production of proinflammatory cytokines which are COX-2 inducers, proven through in vivo, in vitro, and in silico studies in various target cell organs. Conclusion: Propolis extract has high prospect as inflammatory pain inhibitor in the pulp by inhibit COX-2 expression.

Abstract

Background: Deep dentinal caries cannot defect the vitality of dental pulp. The microbial populations involved in dental caries are known to be highly complex and variable. Lactobacillus casei is one of the most common carious dentine bacteria. Tannin contained in mangosteen pericarp extract is known to have an antibacterial potency. Purpose. This study aims to determine the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration of tannin from mangosteen pericarp extract against Lactobacillus casei. Method. This study is an experimental laboratory with a post-test only control group design. Tannin from mangosteen was extracted by 96% ethanol. Lactobacillus casei was diluted into several concentrations using the serial dilution method in the Brain Heart Infusion Broth (BHIB) medium and inserted in several reaction tubes. Every reaction tube was incubated for 24 hours. After being incubated, each concentration was taken and swabbed into Mueller Hinton in the petri dish. Then, every petri dish was incubated for 24 hours and colonies' growth was counted manually in the Colony Forming Unit (CFU). Result. Bacterial colonies' growth at a concentration of 1.56% was 90% less than the positive control group and there was no bacterial colonies growth at the concentration of 3.12%. Conclusion. Tanin from mangosteen pericarp extract has an antibacterial effect against Lactobacillus casei. The MIC of tannin from mangosteen pericarp extract against Lactobacillus casei was at 1.56% and MBC was at 3.12%.

Abstract

Background : White Spot Lesion (WSL) is caused by Streptococcus Mutan which causes demineralization of teeth. One of the treatments of WSL is topical application of fluoride which aims to remineralize the teeth. However, if topical fluoride treatment does not give satisfactory results, alternative treatments can be made using restorative treatments, one of which is veneers. The procedure for applying veneers requires the application of an adhesive system. The adhesive system used to apply veneers is self-etch and total-etch. Several references state that the application of fluoride which aims to remineralize teeth can influence the adhesiv strength of the restorative material using self etch and total-etch techniques. Purpose : To determine the effect of composite resin adhesion strength between total-etch and self etch techniques on enamel after fluoride application. Review : Literature sources used in the preparation of the article through several databases with descriptions of the effects of fluoride application before total-etch and/or self etch administration. From the existing references, it was found that the application of fluoride before the total-etch system had a less significant effect on the adhesiv strength. Whereas in the self etch system, fluoride application has a significant effect on the adhesiv strength. Conclusion : More references say that the application of fluoride before the total-etch system has a better adhesive strength than the application of fluoride before the self etch system

Abstract

Background: Free radicals are molecules without any electron pairs, unstable, and highly reactive. Antioxidants are needed to reduce free radicals. Antioxidants provide various benefits in dentistry as a preventive agent for caries, healing, bone formation, mouthwash, preventive and therapeutic cancer, and reduction of periodontal disease progressions. Additionally, research on antioxidants is still undergone due to the existence of free radical residues on bleached teeth. Epigallocatechin-3-gallate (EGCG), ascorbic acid (AA), and sodium ascorbate (SA) are ingridients that have antioxidant properties. Antioxidants can be in two forms solution and gel. Solutions have a higher substance releasing power than gel. Gel is extremely adhesive, so it does not flow easily. Meanwhile, solutions are rather unstable because it flows easily. Antioxidant activities were evaluated with 2,2-diphenyl-1-picrylhydrazyl (DPPH) Assay method. Purpose: Analyzing through literature reviews the potential antioxidants of EGCG, AA, and SA in solution and gel forms by DPPH Assay. Reviews: There were eight journal articles used in this review. The first article described antioxidant solutions in which EGCG was higher than sodium ascorbate. The second article showed that antioxidant gel EGCG was lower than sodium ascorbate. The third journal explained that ascorbic acid was higher than sodium ascorbate both in solution and gel forms. The other articles provided some information about the antioxidant activity percentages of EGCG, SA, and AA in the forms of gel and solutions by DPPH assay. Conclusion: EGCG has a higher antioxidant activity than SA, but it is lower when compared to AA in both solution and gel forms by DPPH assay.

Abstract

Background: Tooth discoloration can be treated with dental bleaching using Hydrogen peroxide (H2O2). Dental bleaching may interfere with the shear bond strength of composite resins because the remaining free radicals can affect bonding polymerization. Epigallocatcehin-3-gallate (EGCG) as an antioxidant can neutralize the free radicals produced during bleaching process. Purpose: Analyze the role of EGCG antioxidants in increasing the shear bond strength of composite resin after bleaching.. Reviews: Of the seven journals included in this literature review, six journals reported significant difference, and one journal noted no significant difference in the shear bond strength of composite resin following the EGCG application. Conclusion: The use of EGCG can increase the shear bond strength value of post-bleaching composite resin restorations.

Abstract

Background: Lactobacillus takes role in the formation of dental plaque which is the main factor that cause dental caries. The bacteria take role in the metabolism of glucose in the mouth, producing organic acids which lower the pH in the oral cavity. This situation can lead to the formation of dental caries because these bacteria can form biofilm as a defense of microorganisms to antibiotics and the immune response. Mangosteen peel has active ingredients such as flavonoid that can be used to inhibit biofilm. The ability of flavonoid compounds in the phenol group can make the bacterial enzyme becomes inactive, causing the activity of glucosyltransferase enzyme that usually used by bacteria to synthesize sucrose in the medium becomes glucan. As a result, bacterial biofilm formation is inhibited because the amount of glucan as a medium of bacterial attachment is limited, but until now the effectivity dose of flavonoid from mangosteen peel extract (Garcinia mangostana Linn.) is has not known yet Purpose: The aim of this study was to determine the inhibitory efficacy of flavonoid of mangosteen peel extract against the formation of Lactobacillus acidophilus bacterial biofilm. Methods: Bacteria that had been formed into biofilms was studied in two times treatment, one concentration reviewed by flavonoid from mangosteen peel extract and without reviewed by flavonoid from mangosteen peel extract. The treatment group was incubated at 37°C until day 8 since the first day incubated. The treatment group was washed with phosphate buffered saline (PBS) 4 times and dried. The treatment group stained with 0.2 ml 0.1% crystal violet and 15 min incubation. The treatment group was rinsed with distilled water 3 times and then dried. Solvent DMSO 100% was added as much as 0.1 ml in each well. Microtiter plate was shaken for 1 minute and then placed in to the microplate reader and then the OD (Optical Density) can be read. Results: There were significant differences between the inhibitory efficacy of flavonoid of mangosteen peel extract against Lactobacillus acidophilus biofilm bacteria, the control group and group treatments (p <0.05). Conclusion: Flavonoid of mangosteen peel extract with the concentration of 0.78% had inhibitory effect against Lactobacillus acidophilus biofilm bacteria
