Abstract

Introduction: Nanocomposite has been developed as a dental restoration. Nano-scale filler can result in high mechanical properties and good esthetic. Nanofiller materials such as partially stabilised zirconia (PSZ) has been recommended for dental use. This form of zirconia can be stabilised by the addition of several different oxides such as magnesia and calcia. Chitosan as a coupling agent was able to increase the nanocomposite’s mechanical properties. The purpose of this research was to evaluate the nanocomposite’s hardness value with and without the addition of chitosan as a coupling agent as well as a different stabiliser of zirconia filler. Methods: Procedures of this research consisted of several stages which were the fabrication of nanocomposite and mechanical properties measurement using the Vicker’s hardness testing. Results: The nanocomposite’s hardness value (kg/mm2) with zirconia filler stabilised by MgO without the addition of chitosan was as much as 5.09 and with the addition of chitosan was 7.51; the nanocomposite ’s hardness number with zirconia filler stabilised by  CaO without the addition of chitosan was 8.16 and with the addition of chitosan was 13.13.  The results were then analysed statistically using the Analysis of Variance (ANOVA) test and showed a significant difference between all of those data groups. Conclusion: The addition of chitosan as well as different stabiliser (MgO and CaO) of Zirconia filler had affected the nanocomposite ’s hardness value.

Abstract

Abstract: Irreversible hydrocolloid impression materials or alginate is commonly used in dental practice. Its setting time range is 1–4.5 minutes. The setting time is affected by several factors such as water temperature mixed with the alginate powder. There are previous studies evaluated the effect of water temperature on the alginate’s setting time, however, the collected data is still minimal. Therefore, this study aimed to evaluate the effect of water temperature on alginate’s setting time on larger scale. There were total of 423 samples divided into three groups: cold, moderate, and warm temperature of water mixed with alginate; each group consisted of 141 samples. Differences in setting times of the qroups were analyzed with the Kruskal-Wallis test and the Tukey’s HSD. Alginate powder used in this study was the normal-set type. Mixing the alginate powder with water was performed as the factory instruction, and then the mixture was poured into molds and the setting times were measured. The results showed that the setting times of the three groups were significantly different. Group I (cold) had the highest setting time (211 seconds), followed by Group II (room temperature) which was 147 seconds, and Group III (warm) had a setting time of 106 seconds.  In conclusion, water temperature has an effect on setting time, that is, the higher the temperature, the faster the setting time, and vice versa.

Abstract

β-Tricalcium phosphate (β-TCP) is a widely used bioceramic material. In dentistry, it is commonly used as bone graft material. β-TCP is osteoconductive, bioresorbable, bioactive, and has biocompatibility properties. This study aims to evaluate the optimum molarity of CaO and H3PO4 to synthesize β-TCP from a natural source (Perna viridis linn). This is laboratory experimental research conducted by reacting calcium compounds from green mussel shells and phosphoric acid using the dissolution precipitation method with variations in molarity ratio. X-ray diffraction (XRD), scanning electron microscope (SEM), and fourier transform infrared (FTIR) were used to identify the characteristics of β-TCP synthesized from green mussel shells. The XRD chart pattern showed the formation of peaks identical to the β-TCP (Sigma-Aldrich). However, formation of whitlockite phase was also seen in the results. FTIR results showed that phosphate, hydroxyl, and carbonyl groups were shown on the graph and could be identified as β-TCP. SEM characterization showed that the sample consisted of small particles irregularly shaped to form like aggregates. β-TCP synthesized using molarity ratio of 0.6M CaO: 0.4M H3PO4 had characteristics resembling β-TCP (Sigma-Aldrich).

Abstract

Titanium is a gold standard material in dental implant treatment due to its biocompatibility and excellent mechanical strength. However, titanium has no bioactivity and osteoconductivity. This has led to studies to develop the osteoconductivity by modifying the surface morphology, such as the thread pitch, which affect the implant stability and bone formation around the implant. This study aims to evaluate the effect of various size of gaps (equivalent to thread pitch) on the bone formation in titanium rods implantation. Initially, titanium rods were cut with different blade sizes: 0.2, 0.3, and 0.4 mm. The gaps were equivalent to dental implant thread pitch. Titanium rods were implanted in the rat’s femur and inserted into the bone marrow. After 2 and 4 weeks of implantation, the rats were euthanized and the implanted femur were extracted. The femurs were resin-embedded and cut into 1-mm thickness. The specimens were observed by backscattered SEM. Two weeks after implantation, new bone started to form and penetrated the pitch. In the wider gaps, the bone penetration was found to be particularly high, and vice versa. After 4 weeks, the new bone formation was greater compared to 2 weeks of implantation, and more bone penetration was observed in the wider pitch. This study is an observational research with qualitative reading of the backscattered SEM images. In conclusion, wider pitch could increase osseointegration by providing larger space for bone formation.

Abstract

Background: Fabrication of the composite scaffold was carried out by combining chitosan, gelatin, and β-tricalcium phosphate (βTCP) derived from limestone. The extraction of βTCP was based on the abundance of limestone containing calcium carbonate, which can be a source of βTCP synthesis. Purpose: This study evaluates the degradation of the combination of chitosan–gelatin (ChG) and chitosan–gelatin–βTCP (ChG-βTCP) composite scaffolds. Methods: The freeze-drying method was used to obtain the composite scaffold, which was a mixture of chitosan, gelatin, and βTCP. Degradation was measured by immersing the samples in a simulated body fluid solution at 37°C for 3, 7, 14, and 21 days. For statistical analysis, one-way analysis of variance (ANOVA) and post hoc Fisher's least significant difference were performed. Results: The ChG scaffold shows better degradability than the ChG-βTCP scaffold. The ChG scaffold shows higher weight degradation than the ChG-βTCP scaffold up to 21 days. Conclusion: In conclusion, the scaffold containing βTCP has lower degradation than the ChG scaffold.

Abstract

Background: Glass ionomer cement (GIC) is a dental material often used in clinical practice. However, its use is limited due to its drawbacks. Natural resources such as propolis have been used to mainly enhance GIC’s antibacterial properties, but other properties attributed to this enhancement also require evaluation. Purpose: The study aims to evaluate the surface hardness, the surface roughness, and the water absorption of GIC containing ethanolic extract of propolis (EEP) from Trigona spp. Methods: Samples in this study were divided into four groups: GIC (control group); GIC + 25% EEP; GIC + 30% EEP; and GIC + 35% EEP. Surface roughness was measured using a surface roughness tester. Surface hardness was measured using a micro-Vickers hardness tester. Water absorption was measured by weighing the samples before and after immersion in distilled water. Surface characterization was carried out using a scanning electron microscope (SEM). Data was statistically analyzed using the Shapiro–Wilk normality test and one-way variance analysis along with the post-hoc Tukey’s test to determine significant differences between all four samples. Results: The statistical test showed significant differences in surface hardness and surface roughness between the control group and the GIC + EEP group. However, the test demonstrated no significant differences in water absorption between the control group and the GIC + EEP group. Conclusion: The addition of EEP to conventional GIC can affect its physical properties.

Abstract

Gypsum is a material that is commonly used in dentistry as study model or working model. The accuracy of the working model is influenced by the absence of defects in the model. Dental students need to know the gypsum setting time in order to avoid fracture of the model when opening the model from negative impression before reaching final setting time. Gypsum setting time can be affected by several factors such as water temperature, water ratio, room temperature and mixing speed. Measurement of gypsum setting time has been done before, however, the number of samples used was still few. Therefore, the aim of this study was to determine the setting time of gypsum with different water/powder ratio on a big number of samples. This research was done by dental students of Faculty of Dentistry, Universitas Trisakti as one of Dental Material’s Courses. A total of three types of water ratios were used in this study, namely 27 cc, 30 cc and 33 cc (n = 141). Type III gypsum powder was weighed with the same weight of 100 gr and then mixed by different water ratios for 60 seconds. Gypsum mixture was placed on a container and vibrated for 60 seconds to eliminate pores. The placement of a small needle to measure the setting time begins at the 150th second and was repeated in multiples of 30 seconds until the tip of the needle did not penetrate the gypsum mixture. The results showed that more water ratio caused the setting time of gypsum type III increased.

Abstract

Nanohybrid composite resin is well-known because of its good aesthetic properties. It has high water sorption, allowing various coloring substances such as papaya juice to penetrate. Papaya juice enzymes may also cause a rougher composite resin surface. This study determined the effect of papaya juice on color and surface roughness of nanohybrid composite resin using laboratory experiment. This study used posttest with control group design containing 27 samples of nanohybrid composite resin (B & E Korea XS-FIL A3.5) with diameter of 10 mm and thickness of 2 mm. The samples were divided into 3 groups: immediate, control, and treatment group. The samples of immediate group were tested directly for color and surface roughness. The treatment group was immersed in papaya juice for 3 hours followed by 21 hours in distilled water, while the control group was immersed in distilled water for 24 hours. All samples were immersed in an incubator at 37 °C for 4 days. Changes in color and surface roughness were tested using a VITA Easyshade V spectrophotometer and a Taylor Hobson surface roughness tester, respectively. ANOVA and post hoc Tukey showed a significant (p < 0.05) change in color (p = 0.003) and surface roughness (p = 0.000); significant (p = 0.033) color change was obtained between the immediate group (E = 6.933) and the treatment group (E = 7.959). In terms of surface roughness, significant (p = 0.000) results were obtained between the treatment group (Ra = 1.974 μm) with the immediate group (Ra = 1.411 μm) and the control group (Ra = 1.404 μm). In conclusion, papaya juice causes changes in color and surface roughness of nanohybrid composite resin.

Abstract

The surface roughness of an implant material (titanium alloy) is an important factor in optimizing osseointegration. Various efforts have been made to optimize the roughness of implant materials, such as acid etching. Previous research showed etching with sulfuric acid ((H2SO4)) at a temperature of 60 °C for 60 minutes could increase roughness. However, further research is needed regarding the concentration of H2SO4 that can optimize surface roughness. This research aimed to determine the concentration of H2SO4 that can be used to obtain optimal roughness. This study used a pre-test and post-test group design by immersing titanium alloy plates in a solution of saline water (negative control), 12.17 M HCl (positive control), and (H2SO4) at various concentrations, namely 6.94 M, 9 M, and 11.06 M for 60 minutes at 60 °C. Next, a surface roughness test and Scanning Electron Microscopy (SEM) were carried out. The research results were analyzed statistically using the Shapiro-Wilk, Wilcoxon, Kruskal-Wallis, and Mann-Whitney tests. The results showed that in the (H2SO4) group, there were significant differences before and after treatment (p < 0.05). The higher the concentration of (H2SO4) used, the higher the surface roughness value. The SEM test showed that the group with a higher (H2SO4) concentration had a rougher topography and more visible grooves. In conclusion, etching with (H2SO4) can increase the surface roughness of titanium alloys, and (H2SO4) at a concentration of 11.06 M led to the highest roughness value in this study.
