Tujuan utama penelitian ini adalah menguji pengaruh faktor-faktor sosial-demografi, sosial-budaya dan keberagamaan terhadap sikap mahasiswa perguruan tinggi mengenai peran jender. Responden adalah 269 mahasiswi dan 179 mahasiswa perguruan tinggi negeri di wilayah Jatinangor, Sumedang, Jawa Barat yang sedang mengikuti perkuliahan semester genap tahun 2012. Responden berasal dari program studi sarjana Ilmu Hukum, Ilmu Keperawatan, Ilmu Kesejahteraan Sosial, dan Ilmu Pemerintahan yang rata-rata berusia 19,7 tahun (SD=1,1). Penentuan sampel dilakukan secara non- random dengan menggunakan convenience sampling technique. Data dikumpulkan melalui pengisian kuesioner terstruktur oleh para responden. Penelitian ini menunjukkan kecenderungan sikap mahasiswa yang ambigu atau inkonsisten terhadap peran jender. Meskipun secara umum mahasiswa mendukung kesetaraan kesempatan dan peran laki-laki dan perempuan dalam pekerjaan dan pendidikan, sebagian besar masih mendukung adanya segregasi peran laki-laki dan perempuan dalam kehidupan keluarga dan masyarakat yang pada prinsipnya memberikan keistimewaan dan kebebasan yang lebih besar kepada laki-laki. Analisis regresi menunjukkan bahwa jenis kelamin, agama, orientasi kekerabatan, dan tingkat keberagamaan secara statistik memiliki asosiasi signifikan dengan sikap mahasiswa mengenai peran jender. Jurusan, masa kuliah, dan latar belakang lingkungan masa kecil dan remaja tidak menunjukkan asosiasi yang signifikan dengan sikap mahasiswa. Dalam kerangka pendidikan berwawasan jender, penelitian ini merekomendasikan pengembangan metode untuk penelitian di masa yang akan datang. Penelitian juga merekomendasikan pentingnya transformasi dan peningkatan sikap yang mendukung kesetaraan jender di kalangan mahasiswa perguruan tinggi. Materi-materi berwawasan jender perlu diintegrasikan ke dalam kurikulum akademik dan kegiatan kemahasiswaan. Kata kunci: sikap mahasiswa, peran jender, kesetaraan laki-laki dan perempuan, lembaga pendidikan tinggi

Endodontic treatment of anterior trauma and caries followed by post and crown restoration is not included in the minimum standard of oral care in primary health facilities. Endodontic treatment, which requires a relatively long time and the number of visits compared to mere tooth extraction, often makes it impossible to carry out in a health facility with many patients per day. This community service was aimed to provide technical understanding and knowledge of endodontic treatment procedures for anterior teeth that are simple, up-to-date, with a minimum number of visits, and provide an understanding of the selection of dental fibre post materials that meet reasonable material requirements at a more affordable price. Methods for implementing the activities consisted of: (1) Formulation and preparation; (2) Pre-test; (3) Expert lecture; (4) Live demo; and (5) Post-test. This community service increased the knowledge and ability in endodontic treatments for anterior teeth and their restoration with dental fibre posts from the prospective dentists and dentists who were participants in this community service. This activity can also lead to the making of the latest manual and standards for endodontic treatment for anterior teeth and their restoration with dental fibre posts.

Sampel kontrol L0 memperlihatkan lapisan TiO2 lebih tinggi dibandingkan sampel L1, L2 dan L3 dengan angka ketebalan masing-masing sebagai berikut: 135 , 70.5, 104 dan 92 μm. Simpulan: Prototipe implan gigi titanium yang dimodifikasi permukaan dengan metode alternate soaking process dengan konsentrasi CaCl2 200 mmol/L dan Na2HPO4 20 mmol/L menghasilkan mikrostruktur berporus yang berpotensi lebih optimal dalam menginduksi pertumbuhan jaringan tulang.Kata kunci: implan gigi; titanium; modifikasi permukaan; alternate soaking process ABSTRACTIntroduction: Several methods have been developed to improve the osseointegration process of titanium implants, including the alternate soaking process. This method was proven to create porosity roughness and CaP compounds on implants through immersion in a solution of CaCl2 and Na2HPO4. The study aimed to determine the microstructure of the surface-modified titanium dental implant prototype using the alternate soaking process method with different concentrations of CaCl2 and Na2HPO4. Methods: A descriptive exploratory research was conducted on the samples, which were titanium implant prototype sized 20x15x0.5mm, divided into four categories based on the treatment. Samples without pre-treatment and surface modification were determined as control (L0). Samples with pre-treatment and surface modification using the alternate soaking process method with CaCl2 and Na2HPO4 solutions of 67 mmol/L and 40 mmol/L were determined as L1; concentrations of 200 mmol/L and 120 mmol/L as L2; concentrations of 600 mmol/L and 360 mmol/L as L3. Results: The microstructural examinations showed that samples in the L0 group were not porous, while samples in the L1, L2, and L3 groups appeared to be porous, with the porous size of 80-150, 400-700, and 50-90 m, respectively. Increasing CaCl2 and Na2HPO4 increased the amount of white deposit (CaP) on the titanium implant prototype surface. The samples in group L0 showed a higher TiO2 layer than samples in group L1, L2, and L3 with thickness figures of 135, 70.5, 104, and 92 m, consecutively. Conclusions: Surface modified titanium dental implant prototype with alternate soaking process method with 200 mmol/L of CaCl2 and 20 mmol/L of Na2HPO4 produced a porous microstructure which has the potential to be more optimal in inducing bone tissue growth.Keywords: dental implant; titanium; surface modification; alternate soaking process

Modulus of elasticity is one of the mechanical properties of composite resins affects the resistance to deformation,the strength of bonding with tooth structure and wear resistance. Modulus of elasticity is determined by the volumefraction of filler particles as the inorganic phase composite resin. This literature study aims to evaluate the size,shape and type of filler particles that affect the modulus of elasticity for composite resin. In a constant volumefraction, the larger size of filler material tends to make more rigid while irregular shape of particles produceshigher modulus of elasticity than spherical form of particles. In addition, the type of filler particles also determinesthe modulus of elasticity for resin composite, such as silica as the main type of filler particles will enhance themodulus of elasticity whereas zirconium can result in a higher stiffness. In order to get composite resin restorationwith appropriate modulus of elasticity the necessary knowledge about the effect of different filler particle isrequired.

Gutta percha is used for many functions in dentistry but the most popular is the root canal filler. This root canal filler is not a pure gutta percha but mixed with other materials, such as zinc oxide, wax, resi, and metal salts. The raw material of gutta percha dentistry is obtained from gutta percha tree (Palaquium gutta Baill) which in Indonesia has been cultivated in commercial scale since 1901 in Cipetir Sukabumi, in this location since 1921 is also equipped with its processing plant. This condition is very supportive if that gutta percha will be used as raw material of gutta percha dentistry. However, this material is a raw material that needs to be mixed with other materials in order to conform the standardization in dentistry, for that needed a series of research to be able to make gutta percha dentistry in Indonesia.

Recently, composite resin has been a material option on making provisional crown besides acrylic resin, while waiting for the definitive crown restoration to finish for the next treatment. The purpose of this study was to compare the microhardness between two materials of provisional crown materials that are available in the market, composite resin and acrylic resin. The method used for this study is experimental laboratory. Five samples each from composite resin and acrylic resin were made in disc shape sizes of 6x4mm. The samples were put in artificial saliva with mouth temperature of 37o for 24 hours and tested later using Vickers Hardness tester. Results show the average of microhardness acrylic resin was 9.14 VHN and 10.69 VHN for composite resin. Even though on average number composite resin was higher by 1.55 VHN than acrylic resin, t-test statistics shows there is no significant difference between composite resin and acrylic resin. The conclusion of the research is there is no significant difference between provisional crown composite resin and provisional crown acrylic resin, although on average composite resin has higher hardness number than acrylic resin.
