Abstract

Introduction: Many research proves that fluorapatite cement is one of the materials in dentistry that can restore and treat severe carious lesions. The current research was aimed to study the chemical reaction of calcium phosphate cement (CPC), calcite, and calcium fluoride as a base in fabricating the fluorapatite cement as an anti-caries agent. Methods: The type of research is a descriptive method.  The preparation of DCPA was initially performed by measuring 0.2g of DCPA powder which was prepared for 15 samples. Fluorapatite was fabricated using dicalcium phosphate anhydrous (DCPA), calcite (CaCO3) as the precursor to form carbonate apatite crystal, and calcium fluoride (CaF2). CaF2 will be mixed into sodium dihydrogen phosphate (NaH2PO4) with different percentages, 1%, 5%, and 10%. The samples were then incubated for 24 hours at 37˚C under 100% moisture condition. X-Ray Diffraction (XRD) characterization will be conducted to determine the phase composition and crystallinity of fluorapatite. In addition, the samples were analyzed with the Fourier Transform Infrared Spectroscopy (FTIR) examination to determine the crystal functional group. Results: All of the samples showed a satisfactory setting reaction. The XRD characterization results showed the formation of the crystal apatite phase at 32.43˚ and 32.83˚. The FTIR results indicated the stretching vibration of the fluoride compound at 1400 cm-1. The intensity formation of the apatite crystal phase at particular degrees was not as high as the standard hydroxyapatite data due to the incomplete formation of apatite crystal within 24 hours—the stretching vibration presence in the FTIR graph at 1400 cm-1 proven to be fluorapatite cement. Conclusions: Fluorapatite cement as an anti-caries agent can be fabricated through the mixing process of DCPA, CaCO3, and CaF2 powders with NaH2PO4 solution.

Abstract

Introduction: Varnish fluoride has the ability to prevent enamel demineralization. De-waxed shellac that mostly used for fruits coating, now is applied as varnish fluoride materials. This de-waxed shellac is quite potential since the product can be found from Indonesian sources. The research aims to describe the toxicity effect of varnish fluoride made of de-waxed shellac by measuring the viability of the fibroblast cells. Methods: The research method that was used in this study is in vitro experimental method, which using the tooth that had been smeared with varnish fluoride contacted with fibroblast cells REF (Rat Embryonic Fibroblast) for 4, 8, and 24 hours. The toxicity effect of varnish fluoride was then measured by cell viability. Results The results show that the average cells viability on 4 hours contacted tooth was 88%, while average cells viability on 8 hours contacted tooth was 74%, and lastly the average cells viability on 24 hours contacted tooth was 63%. Conclusion: The conclusion of this preliminary study on cells viability based on toxicity effect of varnish fluoride made from Indonesian de-waxed shellac are different based on contacted time.Keywords: Cell viability, toxicity effect, varnish fluoride, Indonesian de-waxed shellac

Abstract

Background: Macro-sized and inhomogeneous distribution of ceramic filer particles make it difficult to obtain smooth surfaces of dental composite after polishing. Objective. This study aims to synthesize alumina silica (Al2O3-SiO2) fillers using sol gel method with the additives agent chitosan 5%, 10% and polyethylene glycol (PEG) 5% to produce micro particle size and evenly distributed particle as filler dental composite. Methods. The type of research is descriptive explorative. The sol-gel process was utilized to synthesize filler particles of Al2O3-SiO2. TEOS was dissolved in ethanol and mixed with acetic acid as catalyts. Al2(NO3)3 was added into the solution and mixed homogenously. Subsequently, the additive agents (Chitosan 5%, chitosan 10% and PEG) were mixed into the mixture for 30 minutes. Drying the samples for 48 hours at 60°C in the oven. The Dynamic light scattering (DLS) SZ-1 was used to evaluate the size, particle distribution and zeta potential. Result. The results showed that the addition of chitosan 10% produced a smaller size of Al2O3-SiO2 compared to other samples. A homogeneous particle distribution is shown in the sample with PEG 5%. Meanwhile, zeta potential values of the filler particles Al2O3-SiO2 with the addition of chitosan 10% shows the biggest value. Conclusion: The additive agent of chitosan 10% can modify the surface of filler Al2O3-SiO2 in order to inhibit particle growth more effectively but better particle distribution is shown in samples with PEG 5% due to the lower viscosity than chitosan thus it is easily homogenized in the solution

Abstract

Indonesia is one of the world’s resin producers with high species variability. During this time, natural resins that are widely used and circulating in the market are resin damar mata kucing and resin damar batu. Both of these resins damar come from different types of trees and harvesting methods. The research aims to determine the differences in the value of the hardness of the two resins, so that it can be considered of the resin damar uses as basic materials in dentistry. Hardness test was performed on 16 resin samples of resin damar mata kucing and 16 resin samples of resin damar batu using the Shore Hardness Tester (Shore D Durometer) method based on ASTM D2240. From the results of the study obtained an average value of resin damar mata kucing hardness is 35 Hard Durometer, while the average value of resin damar batu hardness is 43 Hard Durometer. Its can be caused by different types of trees and how they are harvested. Resin damar batu are fossilized sap and obtained from Shorea eximia trees by means of collection from the ground. In general, resin damar batu is blackish brown. Meanwhile, yellowish-clear resin damar mata kucing is a resin damar that has less ash and dirty content, because of the way of harvesting is done by tapping directly on the Shorea javanica trees. So, resin damar batu have a higher hardness value than resin damar mata kucing. It can be concluded that resin damar mata kucing and resin damar batu have different values of hardness, which have potentiality as basic materials in dentistry.
