Abstract

Resin composite is one of the restoration materials used in dentistry. The study toward resin composite was being done to improve mechanical properties and the biocompatibilities, one of the ways by using hydroxyapatite filler. State of the aim of this study was to evaluate the hardness number of resin composite with hydroxyapatite filler from fresh water fish bones. The study was true experimental using five samples of resin composites processed with hydroxyapatite filler from fresh water fish bones and five samples of fabricated resin composites (GC Solare P) as a control. Hardness was evaluated using the Vickers microhardness testing machine (Leco). The average hardness number of resin composite processed was 18.384 VHN and resin composite made by factory was 27.952 VHN. The results were analyzed statistically by t independent (α=0.05) and showed significantly difference between resin composite processed with hydroxyapatite filler from fresh water fish bones compared to fabricated resin composite. The conclusion from this study showed that the hardness number of resin composite processed with hydroxyapatite filler from fresh water fish bone is lower than fabricated resin composite.

Abstract

ABSTRACT Ceramics is a dental material used often because of its relatively good strength and aesthetic properties. Ceramics such as zirconia, alumina, and silica have different characteristics and have been synthesized using a bottom-up method separately. Recently, many studies have used chitosan solution to help synthesize nanometer-sized ceramic materials processed using the bottom-up method. This study aims to produce ZrO2-A12O3-SiO2 nanoparticle ceramics, which were synthesized simultaneously using the bottom-up method, and to see the effect of volume concentration of chitosan solution on the resulting ZrO2-A12O3-SiO2 ceramic particles. The composition ratio of ZrO2:Al2O3:SiO2 used is 3:1:1 with a concentration of 0.05M and a total volume of 500ml. The chitosan solution was added with a volume percentage of 0%, 5%, 10%, 15%, and 20%, respectively, and was named samples A, B, C, D, and E. The XRD (X-Ray Diffraction) and SEM (Scanning Electron Microscopy) characterization of the five samples showed nano-sized particles, which were 87 nm, 85 nm, 81 nm, 76 ran, and 76 nm. SEM characterization results show that sample A's particle distribution is not very visible; the particle distribution is only seen in samples B, C, D, and E, while the best particle distribution is seen in sample C. This study concludes that the optimal volume concentration of adding chitosan solution to produce nano-sized ZrO2-A12O3-SiO2 ceramics with good particle distribution is 10% by volume percentage.

Abstract

The surgical sutures is one of the main techniques used for wound closure. In the oral cavity, suture are often used after procedures such as tooth extraction, implant surgery, and various oral and periodontal treatment procedures. The purpose of this article is to provide knowledge to readers, especially dentists and academics regarding the function of sutures, general characteristics, as well as various materials of sutures. Suture which are used in dentistry are different from suture used in other areas of the body due to saliva, high vascularity, and other functions in oral cavity such as, speaking, chewing and swallowing. The ideal surgical suture depends on the type of surgery, the location of the wound, and the general condition of the patient. Suture threads that do not match the conditions of the surgical wound and the patient's condition will prolong the healing process and can cause infection. By improving the knowledge about surgical suture, dentists are expected to be able to choose the most appropriate surgical suture based on the patient's condition. In academic terms, by knowing the various choices of surgical suture materials, academics are expected to be able to know the advantages and disadvantages of the sutures which can also inspire them to improve the quality of existing sutures.

Abstract

Nylon is a biocompatible thermoplastic polymer that is well known for its excellent fracture resistance, making it suitable for fabricating fiber-reinforced composite (FRC)-based dental bridges. FRC is widely used in dentistry. This study aimed to investigate the structural and morphological characteristics of the nylon 6 fiber prepared using five different weights of nylon 6 dissolved in formic acid. The nylon 6 fiber was successfully fabricated via a simple wet spinning method using water as a coagulant. The fiber was then characterized using Fourier transform infrared (FTIR) spectroscopy, optical microscopy, and scanning electron microscopy. FTIR spectroscopy confirmed the presence of nylon 6 characteristics in the fiber in the form of N–H and C=O groups at a specific wave number. The differences in the diameter and morphological shape of the fiber were attributed to the nylon 6 different concentrations. Furthermore, the nylon 6 fiber can be used to produce cost-effective products and realize suitable characteristics for use as an alternative to traditional materials for fabricating direct dental bridges.

Abstract

ABSTRACTIntroduction: Superparamagnetic iron oxide nanoparticles (SPION) has been used in MRI and have the capability to conjugate with different ligands. One of the active ingredients of interest in biomedical application is curcumin (Cur), which has been shown to have anti-inflammatory effect, wound healing property, and anti-cancer activity. However, such conjugation may need to be facilitated by polymer, such as 3-aminopropyltrimethoxysilane (AMPTS). This study aims to describe the effect of coating materials AMPTS and Cur on the physicochemistry of Fe3O4 particles as a diagnostic of oral cancer. Methods: Modified SPIONs were synthesized by a simple coprecipitation method. Fe3O4 particles were characterized using Fourier transform infrared spectroscopy (FTIR) to analyze the conjugation yield. Next, modified SPIONs were analyzed using dynamic light scattering (DLS) to examine size distribution. Furthermore, zeta potential of the particles was examined. Results: DLS showed size increases after modification of SPION with different materials. In addition, there were slight changes in zeta potential. However, FTIR showed no differences in peaks, indicating that no conjugation was successful. Conclusion: Although FTIR showed no differences in peaks, DLS and zeta potential showed changes with different coatings, which may indicate conjugation. However, further analyses must be carried out to quantify the conjugation yield.KEYWORDS: AMPTS, curcumin, iron oxide, oral cancer, coprecipitationPengaruh bahan pelapis AMPTS dan kurkumin terhadap fisikokimia partikel Fe3O4 sebagai teragnostik kanker mulut: studi deskriptifABSTRAKPendahuluan: Superparamagnetic iron oxide nanoparticle (SPION) telah digunakan dalam MRI dan memiliki kemampuan untuk dikonjugasi dengan berbagai ligan. Salah satu bahan aktif yang menjadi sorotan di bidang biomedis adalah curcumin yang memiliki sifat anti-inflamasi, penyembuhan luka, dan aktivitas anti-kanker. Akan tetapi, konjugasi tersebut biasanya memerlukan fasilitator berupa polimer, seperti 3-aminopropyltrimethoxysilane (AMPTS). Penelitian ini bertujuan untuk mendeskripsikan pengaruh bahan pelapis 3-aminopropyltrimethoxysilane (AMPTS) dan kurkumin (Cur) terhadap fisikokimia partikel Fe3O4 sebagai teragnostik kanker mulut. Metode: SPION disintesis dan dimodifikasi dengan bahan-bahan pelapis tersebut melalui metode kopresipitasi sederhana. Untuk menganalisis hasil konjugasi, sampel dikarakterisasi dengan fourier transform infrared spectroscopy (FTIR). Berikutnya, sampel dianalisis dengan dynamic light scattering (DLS) untuk melihat distribusi ukuran. Kemudian, potensial zeta sampel diukur. Hasil: DLS menunjukkan peningkatan ukuran setelah modifikasi SPION dengan bahan pelapis. Selain itu, ada perubahan dalam potensial zeta. Akan tetapi, analisis FTIR tidak menunjukkan perbedaan puncak serapan yang mengindikasikan ketiadaan konjugasi. Simpulan: Meskipun FTIR tidak menunjukkan perbedaan puncak serapan setiap sampel, DLS dan potensial zeta menunjukkan perubahan nilai untuk setiap sampel dengan coating berbeda, yang boleh jadi mengindikasikan konjugasi. Akan tetapi, analisis lebih lanjut perlu dilakukan untuk mengkuantifikasi konjugasi.KATA KUNCI: AMPTS, kurkumin, besi oksida, kanker mulut, kopresipitasi

Abstract

ABSTRACT Introduction: Root canal filling is an important part of root canal treatment that aimed to seal the root canal system, to prevent bacterial penetration and their toxins into periradicular tissues and to provide favourable environment for periapical healing. Thermoplasticized technique were developed to produce filling with homogenous mass, to achieve optimal sealing ability and to increase the quality of root canal filling. The aim of this study is to analyzed differences of Micro-Computed Tomography (Micro-CT) evaluation of the obturation sealing capability between thermoplastic carrier-based condensing techniques and lateral heat condensation techniques. Methods: This study was conducted under an in-vitro quasi experimental methode to 36 specimens of maxillaris centralis incisivus which were divided to 3 groups, (A) thermoplasticized carrier-based technique (GuttaCore System), (B) warm lateral condensation technique (heat carrier SystemB), (C) cold lateral condensation as control group. Sealing ability is evaluated based on the measurement results of volume percentages of filling material and sealer, volume of void, and surface density, that which was calculated from the 3D volumetric image of Micro-CT device. Data were statistically analysed using Analisis of Variance (ANOVA) and t-test. Result: The result showed significant difference of percentage filling material and sealer volume in apical third (p<0.05), whereas there were no significant differences of void volume in apical third, middle third, coronal third or along the canal (p>0.05). Conclusion: Thermoplastized carrier-based technique is not better than warm lateral technique.Keywords: sealing ability; root canal filling; thermoplasticized carrier-based technique; warm lateral technique.

Abstract

ABSTRACTIntroduction: Organic fillers made from the green-synthesis process can be utilized in dental treatment due to their non-toxic characteristic of the oral environment. Dental fillers must be smaller to improve their mechanical, physical, and biological properties. Material processing and centrifugation contribute to the size of processed materials. This study evaluates the effect of different centrifugation speeds on the size and distribution of glutinous rice flour as organic dental filler. Methods: This experimental study uses glutinous rice flour suspended in water and then centrifuged at different speeds of 3000 and 6000 rpm compared to untreated glutinous rice flour as control. The particle size was examined using Scanning Electron Microscope (SEM) and Dynamic Light Scattering (DLS). Next, Fourier Transform Infra Spectroscopy (FTIR) and X-ray Diffraction (XRD) were performed to evaluate whether there were structure and crystallinity changes. Finally, the cytocompatibility of fillers was examined by a cell viability test. Results: Centrifugation of glutinous rice flour at 3000 rpm resulted in smaller average size particles, evenly distributed, and higher crystallinity than other groups. There were no changes in functional groups, as shown by FTIR spectra. However, the processed samples were more amorphous compared to the control. Importantly, the processed samples appeared to be non-toxic, with a range of cell viability of 82.75-86.67% after 24 h incubation. Conclusion: Centrifugation speed of 3000 rpm has decreased in size, and a more homogenous particle size of organic filler made from glutinous rice flour. Importantly, it improved the cytocompatibility of particles compared to untreated control. Altogether, we proposed this organic material as a new potential material in the dental application that can be further investigated. Keywords: centrifugation speed; size distribution; organic dental filler; glutinous rice flour

Abstract

Introduction: Several factor limits of services of dental composite have triggered further improvement. ZrO2-Al2O3-SiO2 system as filler of dental composite had been developed with sol-gel technique. Ultrasonic homogeniser were reported to change the particle size ditribution or shape. Unifom size and distribution of particle is believed to help define the behavior of hardness properties. Methods: The study was an laboratory experimental design. Filler ZrO2-Al2O3-SiO2 system were developed via sol-gel methods. Post calcination process, filler were immerse in ethanol and applied with ultrasonic homogeniser, with various amplitude i.e 50 rpm, 60 rpm and 80 rpm then named sample A, B, and C. XRD, SEM anda PSA were used to characterize of filler system. Subsequent filler were used to fabricate dental composite then evaluate the hardness value using micro-hardness tester. One–way ANOVA was used to analysis the statistical result of hardness value. Results: XRD pattern of three sample were similar in which tetragonal zirconia was prominent (57-61 %) followed by monoclinic zirconia (24-25%) and amorphous (15-17 %). While, SEM and PSA characterization showed amplitude 50 rpm (sample A) produce more uniform size and well-distributed particle filler than the others. In contrary, sample B and C showed higher peak in PSA results. It means there was dominating of filler with particular size.  However, the hardness value did not show significant differences between those filler (p>0,05). Conclusion: Dental composite that contain of different uniformity and distribution of filler ZrO2-Al2O3-SiO2 system has no significantly differences of hardness value.
