Abstract

Teeth with pulp necrosis, whether or not with periapical abnormalities, may be indicated for root canal treatment. Root canal treatment is a treatment carried out with the aim of removing infected dental pulp tissue, necrotic debris, and microorganisms. It aims to make the root canal sterile and can be filled with filling material so that a hermetic density is obtained in the apical area. Root canal treatment consists of three main stages (Triad Endodontics). The endodontic triad consists of preparation, sterilization and root canal filling. These three stages of root canal treatment are very important because not all root canal treatments end with success. The success of root canal treatment can be evaluated after a minimum of six months. Subjective, objective and radiographic examinations need to be conduct for determining the success of the treatment. Root canal treatment is said to be successful if the results of the three examinations are declared good. This type of research is descriptive research. The research method was carried out by subjective, objective and radiographic examination in the study sample who had performed root canal treatment in 2016 that met the criteria of the researcher. The results of the research are included in the table and interpreted with a percentage that is very low to very good. Based on this, it was concluded that the success rate of root canal treatment in non-vital teeth at RSGM University of Jember in 2016 was 54.54% and included in the sufficient category.

Abstract

Introduction: Class V cavity can occur due to horizontal tooth brushing methods. Horizontal brushing and abrasive materials on toothpaste allegedly cause surface roughness in the restorative material. Surface roughness causes the retention of plaque and discoloration that will ultimately affect the aesthetic and durability of the restoration. Glass ionomer cement (GIC), resin-modified glass ionomer cement (RMGIC), and nanofiller composite resin (NCR) are aesthetic restorative materials usually applied to restore the the class V cavity. Objective: To determine the surface roughness of Glass ionomer cement (GIC), resin-modified glass ionomer cement (RMGIC), and nanofiller composite resin (NCR) after brushing with horizontal methods. Methods: This study used a pre and post test control group design. There were three groups, each consisted of 6 samples of bovine’s teeth that was class V prepared and restored. Group 1 NCR, group 2 GIC, and group 3 RMGIC. Each group was brushed with horizontal methods as many as 5,110 movements. The measurements of surface roughness were taken before and after the samples were brushed with surface roughnes tester. Data were statistically analyzed using one way Anova. Result: There were an increase in the surface roughness of each group after brushing. The result showed that the value of surface roughness are as follows GIC > RMGIC > NCR. There were also significant differences among the value of surface roughness in each group. Conclusion: The smallest increase of surface roughness after brushing shows that of nanofiller composite resin, followed by resin-modified glass ionomer cement, and glass ionomer cement.

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.
