Introduction: Nanohybrid composite resins is a type of composite consisting 2 different filler sizes, where one filler ranges in nanoparticles 0.01-0.05µm. Pineapple juice (Ananas comosus) is a widely consumed drink by Indonesian with pH range 3.5-4.6. Surface roughness may be affected by extrinsic factors such as low pH from pineapple juice. Rough surface can cause bacterial adhesion and plaque accumulation on restorative material which cause secondary caries, gingivitis and staining. Preheating is a preparation method of composite which improve composite physical and mechanical properties. Objective: To analyze the difference in surface roughness of preheated and non-preheated nanohybrid composite resins after immersion in pineapple juice. Methods: This research was a laboratory experimental with post-test and control group design. Thirty-three cylindrical sample of nanohybrid composite resin Filtek Z250 XT A2 shade (3M ESPE) (10 mm x 2 mm) were divided into 3 groups: Preheated, Non-preheated and control. Preheated and non-preheated group were immersed in 10 mL pineapple juice for 2 hours for 12 days, control group were immersed in 10 mL distilled water for 24 hours for 12 days. Surface roughness was measured after immersion using surface roughness tester Taylor Hobson, Subtonic S-100 Series-S128) and analyzed using one way ANOVA followed by Post Hoc Tukey. Results: Statistical analyze with one way ANOVA test indicates significant differences between surface roughness in 3 groups with p = 0.034, average surface roughness of pre-heated group was calculated in 0.73 µm, non-preheated group in 0.81 µm and control group in 0.55µm. Tukey’s Post hoc with p = 0.03 shows significant difference in surface of non-preheated composite resin with control group. Conclusion: Pineapple juice increases surface roughness of nanohybrid composite resins after 2 hours immersion for 12 days in comparison with control group.

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.

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.

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.

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.

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.

The utility of dental materials to posing oral diseases have impact in the risk of Bisphenol A (BPA) exposure which can be harmful to human organs. BPA used in dentistry is related to the production of polycarbonate plastics and epoxy resins. For instance, composite filling materials and dental sealant are containing BPA that can promote risk to endocrine-disrupting, estrogenic effect, and renal exposure. The current study is reviewing the BPA exposures of dental materials and it impact risk to the systemic health. This systematic review critically evaluates, and the information gathered form several literatures. The source of these articles was Pub Med and Web of Science, search done with the following terms: BPA of dental materials, BPA exposure, BPA and health risks, BPA, and oral health. BPA exposure found in oral mucosa and saliva after the application of BPA-containing dental materials. BPA derivatives used in dental products have not been evaluated for the endocrine disruptor, estrogenicity. BPA exposures can be absorbed through the oral mucosa and may lead to internal exposures the absorption of BPA from the gastrointestinal tract. Manufacturers should be required to report complete information on the chemical composition of dental materials and strict precaution application techniques must be considered by the practitioner.

Introduction: Giomer is a resin-based restorative material consisting of prereacted glass ionomer (PRG) filler which can release fluoride. Carbonated beverages, popular beverages which contain acids that rich in H+ ions, can diffuse into the resin-based restoration and cause high solubility. Objective: To analyze the effect of immersion in carbonated drinks on water absorption and diametral tensile strength of giomer. Methods: Giomer was packed into a stainless-steel mold to obtain sample with diameter of 6.0±0.03mm and height of 3.0±0.09mm. The samples were divided into 2 groups for water absorption test and 3 groups for diametrical tensile strength test. Ten samples of giomer were soaked in artificial saliva for 4 days as a control group, 10 giomer samples were immersed in carbonated drinks for 6 hours, then replaced with artificial saliva for 18 hours and repeated for 4 days as a treatment group, and 10 samples of giomer were used as immediate group for direct diametral tensile strength test. Samples were incubated at 37°C. Results: Mann-Whitney test showed no significant difference (p>0.05) in giomer absorption between the control group (0.99±0.54%) and the treatment group (2.37±2.62%). One Way ANOVA test showed significant difference (p<0.05) in giomer diametral tensile strength among the immediate group (29.6±3.7MPa), the control group (51.1±3.9MPa) and the treatment group (44.8±5.3MPa). Conclusion: Immersion in carbonated beverages did not show significant difference with artificial saliva for the water absorption ability of giomer. However, the diametral tensile strength of giomer decreased after immersion in carbonated beverages for 24 hours.
