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.

Abstract

Background: Pregnancy gingivitis is known to affect high-risk pregnancies. Therefore, preventive treatments are necessary, one of them being use of  mouthwash. Citronella oil and lemon oil have been proven to have anti-inflammatory properties. The aim of this study was to investigate the effectiveness of a nanoemulsion mouthwash combining citronella oil (Cymbopogon winterianus) and lemon oil (Citrus limon),  on macrophage counts in a pregnant rat model induced with gingivitis. Method: Female Sprague Dawley rats were confirmed to be pregnant, followed by ligation of both lower incisor teeth, and then mouthwash application. The rats were routinely fed a moist diet and drinking water containing 10% sucrose. Mouthwash application was performed twice daily (morning and evening) over 7 day. Histological evaluation was conducted by counting the number of macrophages in hematoxylin-eosin preparations. Result: The results showed a reduction in the number of macrophages with the administration of the nanoemulsion mouthwash combining citronella oil and lemon oil. The Mann -Whitney test revealed a significant difference compared to the control group (p<0.05). Conclusion: The nanoemulsion mouthwash with 1% citronella oil and 2,77% lemon oil may help reduce the number of macrophages in pregnant rats with gingivitis.

Abstract

Using a disclosing agent to control plaque is one way to improve dental health and oral tissue. However, this material is not widely known to the public. Red dragon fruit, a mainstay commodity in Blitar Regency, contains betalain which can be used as an alternative disclosure agent. Therefore, the people of Blitar Regency need to be empowered to maintain dental and oral health regarding the potential of dragon fruit as an alternative natural ingredient. The aim is to provide education regarding the potential benefits of dragon fruit as a disclosure agent. The strategy used in this activity is dual media intervention by dentists, namely by using interactive lectures with PowerPoint media and booklet media to community groups in, Blitar Regency. To measure the level of knowledge of the target community, questionnaires were given before and after the activity, as well as checking the OHI-S index. The research results showed that the level of the OHI-S index was in the medium category, while the level of community knowledge showed an increase of 56.78% after being given counseling. This shows that providing dental and oral health education using PowerPoint media and booklet media has proven to be effective in increasing public knowledge. Therefore, it can be concluded that providing education on the use of red dragon fruit as a disclosing agent to the people of Blitar Regency has proven effective in increasing knowledge, so it is hoped that it can improve the community's dental and oral hygiene.

Abstract

Background: Fiber is added to composite resin with the aim of increasing strength. The strength of composite resin is influenced by water absorption. Samia ricini silk fiber has semihydrophilic properties which can affect water absorption in FRC. One of the ways FRC water absorption is influenced by volumetric fraction. Objective: to determine the effect of the volumetric fraction of Samia ricini silk fiber ribbon in FRC on water absorption. Method: The materials used in this research were flowable composite resin and Samia ricini fiber. The samples were made into 3 groups with varying volumetric fractions of 0%, 25% and 50%, with each group having 6 samples. The sample was then weighed to an accuracy of 0.0001 g, then soaked in water for 7 days in an incubator. After 7 days, weighing was carried out again to calculate the weight percentage of water absorption in the FRC. The data obtained was then analyzed using One Way ANOVA. Results: This research show that water absorption has increased in line with the increase in volumetric fraction. The percentage of water absorption in the volumetric fractions of 0%, 25%, and 50% respectively is 0.5298 ± 0.1190%, 0.8430 ± 0.3191%, and 0.9382 ± 0.4215%. The results of the One Way ANOVA analysis show F = 2.798 with a significance of 0.093 so that the three volumetric fraction groups do not have significant differences. Conclusion: Volumetric fraction does not significantly influence the water absorption of composite resin during 7 days of immersion.
