Abstract

CoCr has high mechanical properties but may release ion in an acidic environment as in the oral cavity. Cobalt (Co) ion can release from CoCr alloy if such material is immersed in acidic environment. This situation may lead to several consequences including allergies and oral lesions. The aim of this research was to determine the influence of pH degree on acidic saliva to the Co ion release concentration of CoCr L605 alloy. This research used CoCr L605 alloy and artificial saliva. Twelve samples of CoCr L605 metal plates were made into (10x10x1.5) mm size. The samples were divided into three groups; each group immersed in 20 ml of artificial saliva for 14 days, 37o C. The pH variables for the groups are 3, 5 and 7. Co ion released was measured by Atomic Absorption Spectroscopy (AAS). Data analysis was performed by one-way ANOVA (Analysis of Variance). The result showed that the mean of concentration value of Co ion released for group pH of 3, 5 and 7 were (3.0970±0.612)ppm; (2.0250±0.609) ppm; and 0.000 ppm respectively. One-way ANOVA showed that pH degree of acidic saliva significantly influenced by the Co ion release concentration (p<0.05). LSD test showed a significant difference between groups. The conclusion of this research was the less pH degree of saliva, the concentration of Co ion released of CoCr L605 alloy was higher.

Abstract

Glass fiber lebih sering digunakan daripada polyethylene fiber sebagai komponen FRC dalam dunia kedokteran gigi. Glass fiber dental di Indonesia tersedia dalam jumlah terbatas dan memiliki harga yang relatif mahal. Tujuan dari penelitian ini adalah untuk memeriksa komposisi dari E-glass fiber dental dan glass fiber non dental menggunakan teknik XRF sehingga dapat ditentukan tipe dari masing-masing glass fiber non dental. Sampel terdiri dari 10 g E-glass fiber dental, 10 g fiberglass mats, 10 g fiberglass roving dan 10 g woven roving. Masing-masing sampel dihaluskan, selanjutnya dianalisa dengan dengan menggunakan X-Ray Fluorescence Spectrometer (XRF). Hasil analisa XRF sampel menunjukkan kandungan oksida terbesar pada E-glass fiber dental adalah SiO2 (45,47%), CaO (38,49%) dan Al2O3 (12,11%). Kandungan oksida terbesar pada fiberglass mats adalah SiO2 (56,88%), CaO (16,24%) dan Na2O (12,91%) demikian pula dengan woven roving yaitu SiO2 (55,86%), CaO (18,71%) dan Na2O (11,80%). Sedangkan fiberglass roving menunjukkan kandungan oksida terbesar antara lain SiO2 (52,56%), ZrO2 (14,64%) dan CaO (10,03%). Hal tersebut menunjukkan bahwa komposisi kandungan oksida pada sampel memiliki kemiripan dengan persentase yang berbeda. Berdasarkan pada analisis XRF disimpulkan bahwa glass fiber non dental jenis fiberglass mats dan woven roving mengarah ke tipe C-glass dan fiberglass roving mengarah ke tipe AR-glass.

Abstract

E-glass fiber merupakan fiber reinforcement yang sering digunakan di kedokteran gigi karena berikatan baik dengan polimer melalui silane coupling agent, meningkatkan kekuatan mekanis dan tidak sensitif terhadap kelembaban. Ketersediaan E-glass fiber dental di Indonesia terbatas dengan harga relatif mahal. Glass fiber non dental banyak tersedia di Indonesia dengan harga terjangkau, yang biasa digunakan pada pembuatan panel gypsum dan komponen otomotif. Tujuan penelitian ini adalah mengetahui pengaruh komposisi glass fiber non dental terhadap kekuatan fleksural fiber reinforced composites. Bahan yang digunakan dalam penelitian ini adalah E-glass fiber dental (Fiber-splint, Polydentia SA, Switzerland), glass fiber non dental A (LT, China), B (CMAX, China) dan C (HJ, China), flowable composite (CharmFil Flow, Denkist, Korea) dan silane coupling agent (Monobond S, Ivoclar Vivadent, Liechtenstein). Subjek dibagi dalam 5 kelompok: tanpa fiber, E-glass fiber dental, glass fiber non dental A, B dan C . Uji kekuatan fleksural berdasarkan ISO 10477. Hasil yang diperoleh dianalisis menggunakan ANAVA satu jalur. Hasil penelitian menunjukkan rerata kekuatan fleksural (MPa) terendah pada kelompok tanpa fiber (126,18±5,21) dan tertinggi pada kelompok glass fiber non dental A (208,03±8,32). Hasil ANAVA satu jalur menunjukkan pengaruh bermakna dari komposisi fiber terhadap kekuatan fleksural (α < 0,05). Kesimpulan penelitian: Kandungan SiO2, Al2O3 dan alkali tanah oksida (MgO dan CaO) yang tinggi pada glass fiber meningkatkan kekuatan fleksural dari fiber reinforced composites.

Abstract

Synthetic dental fiber tape for fiber reinforcement (FRC) restoration is relatively costly and its availability is still limited in Indonesia, so natural dental fibers have been used as an alternative material. The aim of this study was to assess the effect of impregnation of various fiber tape toward the flexural strength and hardness of FRC. The materials used were natural Bombyx mori silk fibers (Indonesia), dental polyethylene tape (Construct Kerr, USA), dental Quartz tape (Quartz Splint UD, France), dental E-glass tape (Everstick TM, GC, Japan), silane coupling agent (Ultradent, Jordan), and composite resin (Denfil-Flow, USA). Five groups of samples consisted of FRC with various fiber tapes were prepared: unidirectional-silk, braided-silk, quartz, polyethylene, and E-glass. The five groups of FRC were tested to determine the flexural strength and hardness. The results were analyzed by one-way ANOVA, followed by LSD test. The results showed that the highest flexural strength was in the quartz group (496.84 ± 109.14 MPa), while the lowest was in the braided-silk group (139.39 ± 4.30 MPa). The highest hardness property was in the unidirectional-silk group (141.29 ± 25.17 VHN), while the lowest was in the braided-silk group (139.39 ± 4.30 VHN). The ANOVA showed that various fiber tapes significantly influenced the flexural strength and hardness of FRC (p < 0.05). The LSD showed that the unidirectional-silk, braided-silk, and polyethylene groups demonstrated no significant difference. The LSD for hardness showed that the unidirectional-silk group had a significant difference with the other groups (p < 0.05). It can be concluded that various fiber tapes influenced the flexural strength and hardness of FRC. Natural silk fibers showed comparable flexural strength and hardness with the other fiber tapes.

Abstract

Acrylic resin is the material most often used as a base for dentures; however, acrylic resin has shortcomings in its biological properties as it does not have antimicrobial properties. ZnO is added to acrylic resin because of its antimicrobial properties. The aim of this research is to determine the effect of the concentration of ZnO nanoparticles as a heat polymerization acrylic resin coating on the coating’s resistance to abrasion. A total of 24 acrylic resin samples were made, each measuring 13 x 13 x 2 mm. The acrylic resin was coated with 3-(trimethoxysilyl)propyl methacrylate), then with ZnO nanoparticles with varying concentrations of 2.5%, 5%, and 7.5% in ethanol. ZnO nanoparticle coating was applied using the dip coating method. Subsequently, the samples were subjected to an initial roughness test, abrasion test, and final roughness test. The data obtained were analyzed using one-way ANOVA and LSD(0.05). The results showed that the mean change in roughness (μm) and standard deviation for groups I to IV were 0.11 ± 0.13, 0.08 ± 0.33, 0.1 ± 0.12, and 0.19 ± 0.15, respectively. The results of the one-way ANOVA test showed that there was no significant difference in the roughness after the abrasion test (p > 0.05). Thus, zinc oxide nanoparticles can reduce surface roughness and are resistant to surface abrasion.

Abstract

Background: Corncob powder is a promising filler that needs to be assessed when it is incorporated into inlay waxes to modified its properties. Purpose: This study aims to investigate the effect of different concentrations of corncob powder filler on physical and mechanical properties of inlay waxes. Methods: Five groups of inlay waxes were prepared from paraffin, corncob powder, carnauba wax, and beeswax in varying proportions (w/w%), namely, group I (70:0:25:5), II (65:5:25:5), III (60:10:25: 5), IV (55:15:25:5), and V (50:20:25:5). The wax mixture was heated at 80°C, filtered, added with corncob powder, and stirred until homogeneous then poured into mold for melting point, residue on ignition, flow, hardness, and trimming samples. They were based on ANSI/ADA specification no.122 and ASTM D 1321. The data were analyzed through one-way ANOVA, post-hoc LSD, and Tamhane tests (p = 0.05), except trimming test data. Results: One-way ANOVA revealed that the concentration of corncob filler influenced all inlay waxes properties (p<0.05). LSD and Tamhane post-hoc test, showed significant different among mostly between groups of tests. Addition corncob powder increased the melting point, hardness, and residue of inlay waxes but decreased the flow of inlay waxes. Addition corncob did not influence the trimming property of inlay waxes. Conclusion: The concentration of corncob filler added in inlay wax compositions influenced the melting point, flow, hardness and residue properties but did not influence trimming properties. Inlay wax containing 10% corncob filler potential as a local inlay wax, but further research should be done to overcome the residue on ignition property that higher than standards.
