Abstract

The use of zinc oxide eugenol in open pulps is controversial because of the cytotoxic effects of eugenol. Previous research has proven that zinc oxide Allium sativum Linn. extract can be an alternative for pulp capping material because it has antibacterial effect. The materials that applied to the oral cavity must be non-cytotoxic and biocompatible, therefore cytotoxicity testing is required of zinc oxide Allium sativum Linn. extract on human gingival fibroblast cell. To determine the cytotoxicity of zinc oxide Allium sativum Linn. extract on human gingival fibroblast cell. Cytotoxicity test of a mixture of zinc oxide with Allium sativum Linn. extract using ratio 1:1 (group A) and 2:1 (group B), zinc oxide eugenol 1:2 (control group C). Each material is exposed to the human gingival fibroblast cells. The cytotoxicity test was tested using an MTT essay test. The density of optic formazan indicated the number of living cell. Cytotoxicity parameters using IC50. Data were analyzed using one-way Anova test and Tukey HSD test. The number of living cells in group A= 40,400 %, group B= 50,613 % and group C= 51,247 %. There was no significant difference between zinc oxide Allium sativum Linn at a ratio of 2:1 (group B) with zinc oxide eugenol 2:1 (group C). Zinc oxide Allium sativum Linn. extract with a ratio 2:1 were not cytotoxic toward human gingival fibroblast cell.

Abstract

Chocolate is one of the most popular food and beverage in the world. This caused by its good taste and anti-stress effect. Chocolate is a processed food from the seed of Theobroma cacao tree, that contain polyphenols. Chocolate beverage are consumed by everyone, as well as dentures wearers. Acrylic resins heat cured are commonly used to make dentures. This materials properties are water absorbent. Phenols chocolate solution are absorbed into the acrylic resin. This prolonged phenomenon i.e chocolate drinks, will cause changes in the physical and chemical properties of this acrylic resin. The aim of this study is to evaluate surface microstructure of the heat cured acrylic resins specimens after contact with various concentrations of chocolate solutions. Four resin acrylic specimens were processed per manufacturer’s instructions into 10x10x1,5 mm and be polished until glossy. Each specimen was submerged into different concentrations of chocolate solution (6g:200ml, 9g:200ml, 12g:200ml) and aquadest as a control for 24 days. Microstructure changes were observed using a scanning electron microscope (SEM) and energy dispersive x-ray spectroscopy (EDS). There were significant microstructural changes for all samples. The surface microstructural changes of the heat cured acrylic resins are notably higher with the increase of chocolate concentration.

Abstract

Metals, ceramics, and reinforced polymers have all been used as dental post material. “FRC post = Fiber Reinforced Composite Post is very popular at this moment. Many kinds of materials have been explored as fiber reinforcement for this type of post, including carbon. In this study, activated carbon is combined with zirconia (through sol-gel templating) and PMMA, as an alternative material for composite dental post. Activated carbon is extracted from Eucalyptus papuana wood, a natural resource that is very abundant and economical. Purpose, To make an activated carbon-reinforced zirconia composite structure, to study the suitable zirconia-precursor concentration in enhancing the mechanical properties of the post material to besimilar to the commercial composite post. Methods: Eucalyptus- papuana wood was pyrolyzed at 750°C,producing activated-carbon with tubular pores. The synthesized carbon was then combined with zirconia, using sol -gel templating at 4 different zirconia-precursor molarities. After calcination at 900°C, the activated carbon-zirconia structure was impregnated with PMMA. Morphological image of the transverse surface zirconia showedattachment on the tubular wall of activatedcarbon and the tubular pores and were evenly covered with PMMA. The 3-point bending test showed that all the zirconia- precursor concentrations failed to produce flexural strength in the range of commercial posts (450-1100 MPa), but all their elastic moduli are equal with commercial posts (8-50 GPa). The values of modulus of elasticity of this materialwere comparable to the commercial composite posts with the highest value of 24.247 GPa produced from 0.8 M precursor. The higher the precursor concentration, the higher the mechanical properties of the material. Conclusion:the composite PMMA reinforced with activated carbon-zirconia structure was established, the concentrations of the precursor 0.05, 0.1, 0.4, and 0.8 are correspondsto the modulus of elasticity ofcommercial composite post, but none of these concentrations could produce flexural strength equivalent to the commercial posts

Abstract

Nanohybrid composite resin is a type of composite resin restorative material containing micro-sized filler particles incorporated with nanoparticles. Composite resin restoration in the oral cavity can release its filler particles, one of them is aluminum ion. The pH of saliva is varied. This research aimed to determine the influence of salivary pH on aluminum ion solubility of nanohybrid composite resin. The materials used were nanohybrid composite resin Tetric Evoceram (Ivoclar Vivadent, Austria) and artificial saliva with pH of 5.6, 6.7, and 8.0. Twelve disc-shaped composite resin samples sized 5 mm in diameter and 2 mm thick were made. Samples were polymerized using light curing unit for 20 seconds. Composite resin samples were divided into three pH groups (n=4) and then each sample was soaked in 10 mL artificial saliva inside of polyethylene bottle. The immersion was done in the incubator for 14 days at 37ºC. The concentration of aluminum ion in artificial saliva solutions subsequently was calculated using AAS. Data were analyzed using One-way ANOVA (a=0,05). The mean concentration of aluminum ion released into saliva with pH 5.6, 6.7, and 8.0 were 0.538 ± 0.996 ppm, 0.431 ± 0.981 ppm, and 0.350 ± 0.071 ppm respectively. The result of One-way ANOVA showed a significant influence of salivary pH variation to the solubility of aluminum ion on nanohybrid composite resin (p<0,05). LSD test showed a significant difference only between saliva pH 5,6 and 8,0. The conclusion of this research was that low salivary pH increased the solubility of aluminum ion on nanohybrid resin composite in saliva.

Abstract

Comprehensive care is needed in patients with cleft lip and palate. Treatments to be performed on patients include corrective surgery and orthodontic treatment. One of the treatments that should be prepared before corrective surgery is the rehabilitation of the oral cavity. A girl aged 15 years came to the Cleft Center RSGM FKG Unpad to get treatment for her cleft palate. The treatment plan will include pre-bone grafting orthodontic treatment, bone grafting, and the post-bone grafting orthodontic treatment. In preparation for that, rehabilitation of the oral cavity need to be done, including root canal treatment for teeth 11, 26 and 46 that was diagnosed with necrotic pulp, and composite restorations to tooth 25. Treatment is done with manual ProTaper system (hand-use) and the filler selected was gutta-percha because the success rate is high. Root canal treatment on the tooth 11, 26, 46 has been done and achieved the expected results. The patient is now on the stage of pre bone grafting orthondontic treatment. Gutta-percha is an option for root canal filling material, made from natural materials, flexible, and adequate in filling root canals together with sealer, and more stable to degradation. One of the keys to success for correction of cleft lip and palate is the free-infection oral environment that were achieved during the rehabilitation of the oral cavity due to support further treatment stage.

Abstract

Finishing refers to all the procedures associated with shaping, contouring, and polishing. Polishing immediately after restoration composite resin placement is most clinicians performance. Polishing time can effect strength of composite resin restoration. Immediate polishing may increase on both the surface roughness and the water sorption compared to delayed polishing for 24 hours and may lead to color change of composite resin restoration. The objectives of this study was to evaluate the effect of polishing time on color stability of composite resin nano particle after immersion in mouthwash. This research is experimental laboratory design. Total specimen were 20 and divided in two group. The first group was polished immediately and the second group was polished after 24 hours (n=10). Polishing was done by using Enhance (aluminium oxide) with low speed handspiece 15,000 rpm for 15 second. The specimens were immersed in 20 ml herbal mouthwash for 360 minutes. Color measurement of specimen before and after immersion was obtained by stereomicroscope modified with camera digital and used Adobe Photoshop 7.0 program for evaluate L, a, and b value. The L, a, and b value were input in CIELab (Commission Internationale de l’Eclairage L, a, b) formula with ∆E parameter. Data were analyzed using Independent T-test at a significance level of 0,05. Analysis result of Independent T-test showed that there is significant difference of color change value of composite resin polished immediately is higher than delayed polish for 24 hours. Immediately and delayed for 24 hours can effect on color stability of composite resin nano particle. ∆E value in this research was about 0-2 (∆E<3,7), so color change after immersion in herbal mouthwash was not visual perceptible.

Abstract

The need for esthetic on the desirable dental restoration of patients in dental refunctioning is highly improving, both anterior teeth and posterior teeth. Thus, the use of restoration material applied should meet the esthetic, be able to accept mastication load and to prevent secondary caries. To meet those requirements, sandwich restoration using combination material of composite resine and glass ionomer cement can become a choice. Many kinds of glass ionomer cement that can be used as that restoration basis. The purpose of this study was to observe the pressure strength of sandwich restoration based on the glass ionomer cement Fuji® II and Fuji® IX. The samples were sandwich restoration simulations made using round plastic ring cast with diameter of 5 mm, and thickness of 3 mm. A number of 16 rings were fixed using brass plate, 8 rings for sandwich restorasion based on glass ionomer cement Fuji® II and 8 rings for sandwich restorasion based on glass ionomer cement Fuji® IX. Powder and liquid glass ionomer cement were mixed up to be consistently-thick-and-shiny and subsequently inserted into the rings as thick as 1 mm, condensed and allowed to set for 15 minutes. It was then etched, bonded and applied using ligth activated composite as thick as 2 mm, lightened for 40 seconds. The restoration materials that had been set were then taken out from the rings and subsequently tested for their pressure strength using Autograph Szimadzu (Japan). The result of the study showed that the mean of pressure strength of the sandwich restoration based on glass ionomer cement Fuji® IX (56,80 kgf/cm2) was greater than the sandwich restoration based on glass ionomer cement Fuji® II (16,92 kgf/cm2). The Data was analyzed using Mann Whitney test, and it showed significant difference. It is concluded that restoration based on glass ionomer cement Fuji® IX is capable to endure masticating load greater than the sandwich restoration based on glass ionomer cement Fuji® II.
