Abstract

Introduction: Glass ionomer cement (GIC) is a tooth-colored restorative material that is often used by clinical practitioners because it can release fluoride, is easy to apply to teeth and has minimal preparation techniques. The erosion and moisture-sensitive nature of GIC becomes a problem for a long-lasting aesthetic restoration. Therefore, modifications were made to improve its mechanical properties by adding nanochitosan (NCH) from horn beetle (Xylotrupes gideon). Objective: This study aimed to evaluate the effect of adding horn beetle nanochitosan to GIC liquid on the surface hardness and compared with conventional GIC. Methods: Forty cylindrical samples of GIC (GC Fuji® IX Extra, Tokyo-Japan, Lot 1912201) with a diameter of 4 mm and a thickness of 6 mm were divided into 4 groups, namely the GIC control group, GIC modified with 0.5wt%, 1wt%, 2 wt% nanochitosan. Each sample was immersed in artificial saliva for 24 hours and 7 days. Surface hardness before and after immersion was tested using a Vickers Microhardness tester (Shimadzu, Japan). The data were analyzed using the Kruskal Wallis test to determine the effect of horn beetle nanochitosan addition and the Wilcoxon Signed-Ranked test to determine the effect of immersion time on GIC surface hardness. Results: The Kruskal Wallis statistical test showed significant difference (p<0.05) between the control group and the 24 hours treatment group with the addition of 2wt% nanochitosan, which was the highest surface hardness value (133.1 ± 49.0 HV), followed by 1wt% (127.4 ± 25.5 HV) and 0.5wt% (117.7 ± 22.5 HV). The Wilcoxon Signed-Ranked test statistic also showed a significant difference (p<0.05) between the 24-hour and 7-day immersion time with the surface hardness value at 24 hours immersion greater than 7 days. Conclusion: The addition of 0.5wt%, 1wt% and 2wt% horn beetle nanochitosan can increase the GIC surface hardness value. ABSTRAK Pendahuluan: Glass ionomer cement (GIC) merupakan bahan restorasi sewarna gigi yang sering digunakan oleh praktisi klinis karena dapat melepaskan fluor, mudah diaplikasikan pada gigi, dan memiliki teknik preparasi yang minimal. Erosi dan sifat sensitif kelembaban dari GIC menjadi masalah untuk restorasi estetika yang tahan lama. Oleh karena itu, dilakukan modifikasi untuk meningkatkan sifat mekaniknya dengan menambahkan nanokitosan (NCH) dari kumbang tanduk (Xylotrupes gideon). Tujuan: Penelitian ini bertujuan untuk mengevaluasi pengaruh penambahan nanokitosan kumbang tanduk ke dalam cairan GIC terhadap kekerasan permukaan dan dibandingkan dengan Semen Ionomer Kaca (SIK) konvensional. Metode: Empat puluh sampel silinder GIC (GC Fuji® IX Extra, Tokyo-Japan, Lot 1912201) dengan diameter 4 mm dan ketebalan 6 mm dibagi menjadi 4 kelompok, yaitu kelompok kontrol GIC, GIC dimodifikasi dengan nanokitosan 0,5wt%, 1 wt%, 2wt%. Setiap sampel direndam dalam saliva buatan selama 24 jam dan 7 hari. Kekerasan permukaan sebelum dan sesudah perendaman diuji menggunakan Vickers Microhardness tester. Data dianalisis menggunakan uji Kruskal Wallis untuk mengetahui pengaruh penambahan nanokitosan kumbang tanduk dan uji Wilcoxon Signed-Ranked untuk mengetahui pengaruh waktu perendaman terhadap kekerasan permukaan GIC. Hasil: Uji statistik Kruskal Wallis menunjukkan perbedaan bermakna (p<0,05) antara kelompok kontrol dan kelompok perlakuan perendaman 24 jam dengan penambahan nanokitosan 2wt% yang merupakan nilai kekerasan permukaan tertinggi (133,1 ± 49,0 HV), diikuti sebesar 1wt% (127,4 ± 25,5 HV) dan 0,5% (117,7 ± 22,5 HV). Statistik uji Wilcoxon Signed-Ranked juga menunjukkan perbedaan yang nyata (p<0,05) antara lama perendaman 24 jam dan 7 hari dengan nilai kekerasan permukaan pada perendaman 24 jam lebih besar dari 7 hari. Kesimpulan: Penambahan nanokitosan kumbang tanduk 0,5wt%, 1% , dan 2wt% dapat meningkatkan nilai kekerasan permukaan GIC.

Abstract

Bruxism is a repetitive masticatory muscle activity that has received attention in dental literature for its association with dental restoration failures, orofacial pain, neurological disease, and obstructive sleep apnea. As a determining factor in the diagnosis, parameters regarding the type and classification of intraoral and extraoral signs of probable bruxism are needed. This study aimed to identify the intraoral and extraoral signs of bruxism in the literature. A literature search was performed in the National Library of Medicine (PubMed) to identify all the articles published assessing intra and extraoral signs of bruxism. The selected articles were then screened and structurally read by three persons and summarized in PICO tables. Out of 551 initially retrieved references, 39 articles met the inclusion criteria and were thus included in the scoping review. The studies were divided into six categories based on the type of oral signs: buccal mucosa ridge (n=4), masseter hypertrophy (n=3), tongue indentation (n=4), tooth fracture (n=5), torus mandibularis (n=3), and tooth wear (n=20). This study concluded that the available studies utilize various methods in subjective and clinical data collection. Buccal mucosa ridge, tongue indentation, and torus mandibularis were common in subjects with bruxism. The association of masseter hypertrophy and tooth fracture with bruxism is not conclusive. Although studies on tooth wear in bruxism subjects are the most prevalent among other oral signs, no study has been able to establish a direct link between bruxism and tooth wear.

Abstract

Introduction: Resin-modified glass ionomer cement (RMGIC) is a restorative material developed with aim to overcome the weaknesses of GIC which has poor physical properties that can affect the surface roughness. A rough surface is a contributing factor to the accumulation of plaque and development of secondary caries. One of the factors that cause surface roughness is the use of mouthwash. Objective: To determine the effect of two essential oil mouthwashes on the surface roughness of RMGIC. Methods: Fifteen samples of RMGIC (cylindrical, 2 mm high and 10 mm in diameter) were divided into three treatment groups (n = 5 in each group). In group I, the samples were immersed in green tea essential oil mouthwash for 30 seconds. In group II, the samples were immersed in lemon essential oil mouthwash for 60 seconds. In group III, the samples were immersed in distilled water (control group). All the samples were immersed for 21 days at room temperature (37°C), with two repetitions. The surface roughness was then tested using a surface roughness tester (Taylor Hobson S100 Series; AMETEK Inc; United States of America). Results: The data were analyzed using one way ANOVA with Tukey’s Post Hoc test (p <0.05). Statistical analysis with One Way ANOVA test indicates a significant change in the value of surface roughness between the three groups. Tukey’s Post Hoc test with p=0.009 shows a significant difference in testing the effect of green tea essential oil mouthwash. Conclusion: Green tea essential oil mouthwash affected the surface roughness of RMGIC compared to lemon essential oil mouthwash. However, both did not have a significant difference with control groups.

Abstract

Introduction: There are various restoration materials, one of which is microhybrid composite resin. An effective way to increase its compressive strength is by applying glycerin before curing. This can minimize the formation of a layer of OIL (Oxygen inhibition layer) which is formed due to polymerization that interrupted by the contact of composite resin with oxygen. Exposure with acidic solution such as pure coffee solution causing the occurrence of matrix degradation which can decrease the compressive strength of microhybrid composit. The longer its immersed in pure coffee solution, the more polymer bonds are broken and releasing monomer which result in a decrease of compressive strength. Objective: This study aimed to reveal the effects of glycerin application on the compressive strength of microhybrid composite resins immersed in pure coffee solution. Methods: There are 6 sample groups of composite resin namely: group SG, group S, group GK16, group K16, group GK32, and group K32 with 4 samples per group. Each sample made of microhybrid composite resin brand Filtek Z250 shaped disc with a diameter of 4 mm and thickness of 2 mm. Glycerin was applied to the surfaces of three groups before curing, while other groups were not. After treatment, all samples are compressive strength tested using Universal Testing Machine. The data were analyzed using the Two Way ANOVA followed by Post-Hoc LSD test. Result: The groups with glycerin had higher compressive strength than those groups without glycerin application. The non-immersed groups had a higher hardness level than those groups which were immersed. The Two-Way ANOVA test confirmed that there was a statistically significant difference (p<0.05) among all groups. Conclusion: Glycerin application can increase the compressive strength of microhybrid composite resin immersed in pure coffee solution by minimizing OIL formation on its surface. ABSTRAK Pendahuluan: Terdapat berbagai bahan restorasi, salah satunya yaitu resin komposit microhybrid. Cara yang efektif untuk meningkatkan kekuatan tekan resin komposit microhybrid adalah mengoleskan gliserin sebelum curing. Hal ini dapat meminimalisir pembentukan OIL (Oxygen Inhibition Layer) pada permukaan komposit yang terbentuk akibat polimerisasi terganggu oleh kontak resin komposit dengan oksigen. Kontak dengan larutan bersifat asam seperti larutan kopi murni mampu menyebabkan terjadinya degradasi matriks yang dapat menurunkan kuat tekan komposit microhybrid. Semakin lama resin komposit microhybrid direndam dalam larutan kopi murni, maka semakin banyak polimer yang terputus dan melepaskan monomernya yang berakibat penurunan kekuatan tekan. Tujuan: Untuk mengetahui pengaruh aplikasi gliserin terhadap kekuatan tekan resin komposit microhybrid dalam perendaman larutan kopi murni. Metode: Sampel dibagi menjadi 3 kelompok yaitu kelompok kontrol (sebelum perendaman), kelompok perlakuan (diaplikasi gliserin), kelompok perlakuan (tanpa aplikasi gliserin). Tiap sampel dibuat dari resin komposit microhybrid merk Filtek Z250 dibentuk cakram dengan diameter 4 mm dan ketebalan 2 mm. Gliserin diaplikasikan di atas permukaan resin komposit pada tiga kelompok, sedangkan kelompok lainnya tidak. Setelah perlakuan, semua kelompok dilakukan uji kekuatan tekan menggunakan Universal Testing Machine. Data dianalisa menggunakan Two Way Anova dilanjutkan dengan uji Post-Hoc LSD. Hasil: Kekuatan tekan kelompok dengan aplikasi gliserin lebih tinggi dibandingkan tanpa gliserin. Selain itu, kelompok tanpa perendaman dalam larutan kopi murni memiliki kekuatan tekan lebih tinggi dibandingkan dengan perendaman. Hasil uji Two Way ANOVA menunjukkan adanya perbedaan signifikan (p<0,05) antar semua kelompok. Kesimpulan: Aplikasi gliserin dapat meningkatkan kekuatan tekan resin komposit microhybrid dalam perendaman larutan kopi murni melalui minimalisir pembentukan OIL pada permukaannya.

Abstract

Introduction: Most modern society assumes that an attractive appearance is a necessity, including the aesthetics of dental restorations. Nanofiller composite resins are widely used because they can reduce polymerization shrinkage and produce a smooth surface that improves aesthetics. Composite resins can change color due to extrinsic factors such as exposure to exogenous materials, one of which is instant coffee and intrinsic factors such as disruption of the polymerization process. Composite resins can experience polymerization disturbances when their surfaces are exposed to air before being irradiated, thereby disrupting the polymerization process. This is indicated by the formation of an oxygen inhibitor layer (OIL) this layer can reduce the quality of the restoration. This layer cannot be completely removed but the application of glycerin can reduce the formation of the layer. Objectives: To determine the degree of discoloration of nanofiller composite resin coated with glycerin and not due to immersion in instant coffee solution. Methods: The composite resin sample was in the form of a disc with a diameter of 10 mm and a thickness of 2 mm, coated and uncoated with glycerin before irradiation. Samples were immersed in the instant coffee solution for 37 hours and 61 hours. Color changes were observed using the Minolta CR-10 Color Reader. Results: The most obvious color change was in the nanofiller composite resin group that was not coated with glycerin, with an E value of 1.04 with an immersion time of 61 hours. The least color change in the glycerin-coated nanofiller composite resin group, with an E value of 0.91. there was a significant difference in the color changes of the sample group with glycerin and non-glycerin applications. Conclusion: There was color change in the nanofiller composite resin coated with glycerin and non-glycerin. The least color change was in the glycerin-coated group. ABSTRAK Pendahuluan: Sebagian masyarakat modern beranggapan bahwa penampilan yang menarik merupakan suatu kebutuhan, termasuk estetik restorasi gigi. Resin komposit nanofiller banyak digunakan karena dapat mengurangi polymerization shrinkage dan menghasilkan permukaan yang halus sehingga meningkatkan estetik. Resin komposit dapat mengalami perubahan warna akibat faktor ekstrinsik seperti terpapar bahan eksogen salah satunya adalah kopi instan dan faktor intrisik seperti terganggunya proses polimerisasi. Resin komposit dapat mengalami gangguan polimerisasi ketika permukaannya terpapar udara sebelum disinar, sehingga menyebabkan terganggunya proses polimerisasi. Hal ini ditandai dengan terbentuknya lapisan oxygen inhibitor layer (OIL) lapisan ini dapat mengurangi kualitas restorasi. Lapisan ini tidak dapat sepenuhnya dihilangkan tetapi aplikasi gliserin dapat mengurangi pembentukan lapisan tersebut. Tujuan: Mengetahui tingkat perubahan warna resin komposit nanofiller dengan dan non gliserin akibat perendaman larutan kopi instan. Metode: Sampel resin komposit berbentuk cakram diameter 10 mm tebal 2 mm, dengan dan non gliserin sebelum disinar. Sampel direndam dalam larutan kopi instan selama 37 jam dan 61 jam. Perubahan warna diamati dengan menggunakan alat Color Reader Minolta CR-10. Hasil: Perubahan warna terbesar pada kelompok resin komposit nanofiller non gliserin, dengan nilai ΔE 1,04 dengan waktu perendaman 61 jam. Perubahan warna terkecil pada kelompok resin komposit nanofiller yang dilapisi gliserin, dengan nilai ΔE 0,91 dengan waktu perendaman 61 jam. Terdapat perbedaan bermakna pada kelompok sampel dengan dan non gliserin. Kesimpulan: Terjadi perubahan warna pada resin komposit nanofiller yang dilapisi gliserin dan non gliserin. Perubahan warna yang terkecil terjadi pada kelompok yang dilapisi gliserin.

Abstract

Introduction: Most commonly used vital pulp therapy material is calcium hydroxide (Ca(OH)2) but it has several disadvantages. Previous studies found that nano-hydroxyapatite might induce reparative dentin with no tunnel defect and adding collagen can improve hydroxyapatite mechanical properties. The collagen can also increase pulp cell proliferation and differentiation. The addition of Epigallocatechin-3-Gallate (EGCG) to collagen gel can be beneficial in reducing pulp inflammation. Objective: The purpose of this study is to synthesize and analyze the physical characteristics of the nano-Hydroxyapatite-collagen-Epigallocatechin-3-Gallate hydrogel composite. Methods: Nano-hydroxyapatite from chicken egg shells, 0,2 g/mL collagen type I, and 10 mmol/L EGCG each dissolved in 2 mL deionized water with various ratio of nano-hydroxyapatite:collagen, 40:60 (group 1), 50:50 (group 2), and 60:40 (group 3). Each solution was mixed together then 2% HPMC was added into the mixture. In present study, we observed hydrogel composite pH value, gelation time, and injectability analysis. Results: The pH value in 1 hour stirring for each group was 8,05 ± 0,05, 8,43 ± 0,02, and 8,71 ± 0,04. All samples had 1 hour gelation time. Injectability for each group was 90,67%, 91,93%, and 95,03%. Conclusions: The nanohydroxyapatite, collagen and EGCG hydrogel composite has a potential physical characterization to be used as a vital pulp therapy material based on its pH value and injectable ability but further study should be considered in determining ideal gelation time. ABSTRAK Pendahuluan: Bahan perawatan pulpa vital yang paling umum digunakan adalah kalsium hidroksida (Ca(OH)2), tetapi bahan tersebut memiliki beberapa kekurangan. Penelitian sebelumnya menunjukkan nano-hidroksiapatit mampu merangsang pembentukan dentin reparatif tanpa tunnel defect dan penambahan kolagen mampu meningkatkan sifat mekanik hidroksiapatit. Penambahan Epigallocatechin-3-Gallate (ECGC) pada gel kolagen bermanfaat dalam mengurangi respon inflamasi pulpa. Tujuan: Penelitian ini dilakukan untuk mensintesis dan melakukan uji karakteristik fisik komposit hidrogel nano-hidroksiapatit-kolagen-Epigallocatechin-3-Gallate. Metode: Nano-hidroksiapatit dari cangkang telur ayam dilarutkan dengan 0,2 g/mL kolagen tipe I, dan 10 mmol/L EGCG masing-masing ke dalam air deionisasi dengan perbandingan rasio nano-hidroksiapatit dan kolagen, 40:60 (kelompok 1), 50:50 (kelompok 2), dan 60:40 (kelompok 3). Seluruh larutan dicampurkan dan ditambahkan HPMC 2%, lalu dilakukan uji karakteristik gel berupa uji pH, waktu gelasi, dan uji injektabilitas. Hasil: Nilai pH 1 jam setelah pengadukan secara berurutan adalah 8,05 ± 0,05, 8,43 ± 0,02, dan 8,71 ± 0,04 dengan waktu gelasi selama 1 jam. Injektabilitas secara berurutan adalah 90,67%, 91,93%, dan 95,03%. Kesimpulan: Bahan komposit hidrogel nano-hidroksiapatit, kolagen, dan EGCG memiliki karakteristik fisik yang berpotensi untuk digunakan sebagai bahan terapi pulpa vital jika dilihat dari nilai pH dan kemampuan injektabilitas yang diperoleh.

Abstract

Introduction: Tooth-supported overdentures is a simple and cost-efficient modality that helps preserve bone. This concept is completely supported by DeVan’s maxim: “Perpetual preservation of what is left is more important than the exact replacement of what is lost.” The preserved tooth structure beneath the denture base prevents alveolar ridge resorption, enhances proprioception, and improves denture support and stability. Additionally, using copings on the remaining teeth improves the denture’s retention. Case Report: A 49-year-old female patient reported having the chief complaint of difficulty in chewing food due to missing teeth in the upper and lower arch. An intraoral examination revealed a partially edentulous maxillary arch with denture-induced stomatitis as the patient had a faulty maxillary removable partial denture for five years. The mandibular arch was also partially edentulous, and only mandibular left second premolar and right first and second premolar were present. The patient was advised to stop using maxillary removable partial denture (RPD) altogether and was given an antifungal tablet as well as a multivitamin tab and topical clotrimazole. This case report describes prosthodontic rehabilitation of a mandibular’s partially edentulous arch with tooth-supported overdenture using ball attachments and custom-made coping. Conclusion: For edentulous patients with few remaining teeth, a mandibular tooth-supported overdenture is one of the best and most practical, feasible, and comfortable treatment alternatives. The patient was satisfied with the treatment outcome.
