Abstract

Root canal treatment is a step in order to maintain and preserve the tooth. The success rate of root canal treatment depend on the degree of severity illness and treatment techniques are performed. Reciprocal system is a techniques which use rotary one file endodontic. Single visit endodontic on this treatment was chosenbecause this techniques provide distinct advantages, more economical cost and risk contamination can be reduced.Female 25 years-old with irreversible pulpitis in maxillary left first molar, on the X-ray picture of the root canal looks normal without any narrowing. Root canal treatment performed with anesthetic infiltration pehacain 2 %, using rubber dam during treatment to prevent bacterial contamination and access opening. Tooth preparation using rotary one file reciprocal system R#25, previously done by determining work length with apex locator and confirm with X-ray picture. Obturation with single cone gutta percha R#25 and top seal paste, cotton pellet and temporary material filling. Control after 24 hours, percussion is negative, patient feel little ofpain.Success of endodontic is depend on eliminate bacterial product. One visit endodontic with reciprocal technique is a relatively reliable and simple technique for dentist.

Abstract

Dental caries is an endemic disease that high prevalence and severity. Bacteria, such as Streptococcus mutans are the flora of the mouth, potentially cause caries by producing acid that could demineralize enamel of the tooth. The aim of the study wasw to prove the decreasing of the Streptococcus mutans by rinsing 10-days fermented kombucha tea. The design of this study was experimental Randomized pretest and posttest. These research used two groups:each groups contain 13 subjects. One group as a control and one group as a treatment group. The control group rinsed with sterile distilled water and the treatment group rinsed with 10-days fermented kombucha tea. Datas were analized with paired T-test. Result showed that mean of S. mutans bacteria after treated (rinse 10-days fermented kombucha tea) significantly decreased (p <0.05). It was concluded that rinsing with 10-days fermented kombucha tea could decrease number of Streptococcus mutans. Further research was needed to determine the mechanism of kombucha tea.

Abstract

Karies gigi yang mencapai pulpa dapat menyebabkan nekrosis pulpa. Bakteri yang dapat menyebabkan nekrosis pulpa, salah satunya Staphylococcus aureus. Perawatan terhadap nekrosis pulpa adalah dengan melakukan perawatan saluran akar (PSA). Salah satu tahapan dalam PSA adalah sterilisasi saluran akar dengan menggunakan kalsium hidroksida (calcium hydroxide) atau kresotin (cresotin). Penggunaan obat kimia, utamanya dalam jangka panjang, dapat menimbulkan efek samping, sehingga diperlukan bahan alternatif lain yang lebih aman dan alami, seperti penggunaan jintan hitam (Nigella sativa). Zat aktif yang terkandung dalam jinten hitam dapat bersifat sebagai antibakteri diantaranya adalah tannin, terpenoid, saponins, alkaloids. Penelitian ini bertujuan untuk mengetahui efektifitas ekstrak jinten hitam dalam menghambat pertumbuhan bakteri Staphylococcus aureus secara invitro dengan metode difusi agar.  Penelitian ini menggunakan  ekstrak biji jintan hitam (Nigella sativa) dengan konsentrasi 50%, 75% dan 100%. Rancangan penelitian yang digunakan adalah penelitian Post Test Only Control Group Design, yang terdiri dari lima kelompok yakni, kelompok kontrol negatif (aquadest steril), kelompok perlakuan 1 (ekstrak jintan hitam konsentrasi 50%), kelompok perlakuan 2 (ekstrak jintan hitam konsentrasi 75%), kelompok perlakuan 3 (ekstrak jintan hitam konsentrasi 100%) dan kelompok kontrol positif (cresotin). Sampel yang digunakan dalam penelitian ini adalah bakteri Staphylococcus aureus ATCC 25923, dan besar sampel yakni pengulangan sebanyak lima kali untuk setiap kelompok. Hasil uji statistik dengan man witney U terdapat perbedaan yang signifikan antar kelompok dalam menghambat pertumbuhan bakteri Staphylococcus aureus secara in vitro. Simpulan deari penelitian ini bahwa ekstrak jintan hitam (Nigella sativa) dengan konsentrasi 50%, 75% dan 100% dapat menghambat pertumbuhan bakteri Staphylococcus aureus secara in vitro.

Abstract

Abstrak: Banyak produk adat dan kebudayaan lokal terkenal di Kalimantan Timur, selain kekayaan sumber daya alam, salah satunya adalah pabrik kain batik Shaho. Berdasarkan hasil survei, pusat kerajinan batik Shaho sampai saat ini masih menggunakan pewarna kimia sintetis yang bersifat genotoksik, karsinogen dan merupakan polutan berkategori B3. Tujuan dari kegiatan adalah memperkenalkan rancangan alat ekstraktor untuk produksi pewarna alami kain batik dengan bahan baku serbuk kayu khas hutan Kalimantan (Ulin dan Bangkirai) serta memberikan wawasan dan pengetahuan kepada mitra melalui pengenalan teknologi ekstraksi modern untuk pembuatan pewarna alami kain batik. Mitra pada pengabdian ini adalah pemilik usaha batik Shaho yang berlokasi di kelurahan Batu Ampar, jalan LKMD RT. 5, No. 45 Balikpapan. Peserta terdiri dari pekerja mitra Batik shaho sebanyak 10 orang, pemilik usaha batik 2 orang dan masyarakat sekitar sebanyak 8 orang. Dari kuesioner yang terdiri dari 10 pertanyaan kepada 20 peserta menunjukkan bahwa wawasan pekerja pusat kerajinan batik meningkat tentang pembuatan ekstrak pewarna alami dari serbuk kayu dengan alat ekstraktor sebelum demonstrasi dengan indeks capaian sebesar 60 % naik menjadi 90% sesudah demonstrasi. Peserta memberikan respon positif terutama pada inovasi alat ekstraktor dan produk pewarna kain alami. Produk pewarna cair alami dari ekstrak serbuk kayu ini diharapkan dapat dikembangkan menjadi produk pewarna padat alami dari serbuk kayu yang pemanfaatannya lebih tahan lama serta dari segi pengemasan lebih ekonomis. Abstract: Many traditional and local cultural products are famous in East Kalimantan, in addition to the wealth of natural resources, one of which is the Shaho batik cloth factory. Based on the survey results, the Shaho batik craft center is still using synthetic chemical dyes that are genotoxic, carcinogenic and are B3 category pollutants. The purpose of the activity is to introduce the design of an extractor tool for the production of natural batik dyes with raw materials from Kalimantan forest sawdust (Ulin and Bangkirai) and to provide insight and knowledge to partners through the introduction of modern extraction technology for making natural batik dyes. The partners in this service are the owners of the Shaho batik business located in Batu Ampar Village, Jalan LKMD RT. 5, No. 45 Balikpapan. Participants consisted of 10 Batik shaho partner workers, 2 batik business owners and 8 people from the surrounding community. From the questionnaire consisting of 10 questions to 20 participants, it showed that the insight of the batik craft center workers increased about making natural dye extracts from sawdust with an extractor tool before the demonstration with an achievement index of 60% increasing to 90% after the demonstration. Participants gave positive responses especially to the innovation of extractor tools and natural fabric dye products. Natural liquid dye products from sawdust extract are expected to be developed into natural solid dye products from sawdust which are more durable and more economical in terms of packaging.

Abstract

Introduction: Nanohybrid composite resin is widely used due to its favorable esthetic and mechanical properties. Surface hardness is an important property influencing resistance to masticatory forces and wear, and it depends on the effectiveness of polymerization. Inadequate light-curing can reduce cross-link formation, resulting in lower hardness. This study evaluated the effect of different light-curing durations on the surface hardness of nanohybrid composite resin. Materials and Methods: This in vitro experimental study used a post-test-only design with 27 samples of Filtek Z250. Samples were divided into three groups based on light-curing durations of 20, 30, and 40 seconds. Surface hardness was measured using a Vickers Hardness Tester. Data were analyzed using One-Way ANOVA followed by Tukey HSD post hoc test. Results and Discussion: The mean surface hardness values for 20, 30, and 40 seconds were 82.52 VHN, 84.69 VHN, and 92.85 VHN, respectively, showing increased hardness with longer curing time. A significant difference was found between the 20-second and 40-second groups (p < 0.05), while no significant differences were observed between 20 vs 30 seconds and 30 vs 40 seconds (p > 0.05). These findings indicate that longer light-curing improves polymerization and enhances surface hardness. Conclusion: Light-curing duration significantly affects the surface hardness of nanohybrid composite resin, with longer curing times producing higher hardness values.
