Introduction: Gutta-Percha (GP) is a standard endodontic filling material found in pure form in the Cipetir area, Indonesia. However, a study comparing physical properties (brittleness and flowability) between pure GP and commercially used GP has not been found. Therefore, this study aims to test the brittleness and flowability of Cipetir GP compared to commercial GP. Methods: This study was quasi-experimental. Forty samples were prepared for each material and test, according to ANSI/ADA specification-GP cones-no 78 in 2006. The first step began by making a sample of Cipetir GP using moulds from a cuvette, commercial GP (Inline #80), and gypsum stone. The second step was to test the brittleness (Crease Recovery Tester) and flowability (according to ADA No. 78 of 2000) of Cipetir GP and commercial GP. Results: The brittleness test of Cipetir GP showed unbroken samples, and the commercial GP showed four broken samples. The Fisher's Exact test showed a p-value of 0.087, which means there was no significant difference in brittleness between Cipetir GP and commercial GP. At the same time, the average value of flowability of Cipetir GP and commercial GP were 6.46 mm and 0.19 mm, respectively. The unpaired t-test showed a p-value<0.05, which means there was a significant difference in the flowability between Cipetir GP and commercial GP. Conclusions: There is a brittleness similarity between Cipetir GP and commercial GP, while the flowability value of Cipetir GP is higher than commercial GP. Those initial findings showed that the Cipetir GP might become an excellent candidate to be an alternative endodontic filling.

Introduction: Varnish fluoride has the ability to prevent enamel demineralization. De-waxed shellac that mostly used for fruits coating, now is applied as varnish fluoride materials. This de-waxed shellac is quite potential since the product can be found from Indonesian sources. The research aims to describe the toxicity effect of varnish fluoride made of de-waxed shellac by measuring the viability of the fibroblast cells. Methods: The research method that was used in this study is in vitro experimental method, which using the tooth that had been smeared with varnish fluoride contacted with fibroblast cells REF (Rat Embryonic Fibroblast) for 4, 8, and 24 hours. The toxicity effect of varnish fluoride was then measured by cell viability. Results The results show that the average cells viability on 4 hours contacted tooth was 88%, while average cells viability on 8 hours contacted tooth was 74%, and lastly the average cells viability on 24 hours contacted tooth was 63%. Conclusion: The conclusion of this preliminary study on cells viability based on toxicity effect of varnish fluoride made from Indonesian de-waxed shellac are different based on contacted time.Keywords: Cell viability, toxicity effect, varnish fluoride, Indonesian de-waxed shellac

The surface hardness level of a denture base material is related to the resistance to abrasion, scratch, polishing and water sorption. Nowadays, thermoplastic nylon resins and heat-cured acrylic resins are used as denture base materials. Denture base must be immersed in water to maintain its humidity. The objective of this research was to compare the surface hardness level between thermoplastic nylon resins and heat-cured acrylic resins. Materials used for the research were thermoplastic nylon resins from Valplast and heat-cured acrylic resins QC-20, with a sample size of 64x(10±0.03)x(2.5±0.03) mm. Surface hardness is measured with Vickers Microhardness Tester and the data were analyzed by ANOVA method. The results showed that comparison ratio of surface hardness level between thermoplastic nylon resins and heat-cured acrylic resins before immersion is 3.2:7.3 VHN respectively, while the comparison value of both resins after immersion is 2.8:6.6 VHN. In conclusion, the surface hardness level of thermoplastic nylon resins is lower compared to heat-cured acrylic resins. This result is due to thermoplastic nylon resin’s higher porosity, its different polymer chains, and the plasticizers effect after immersion in water.

Dentistry today has inherited technological advancement from other Dental Material sciences, examples are Nanocomposite and Giomers. Nanocomposites and Giomers are common materials used in Dentistry. But what are the implications when these materials are used in practice? The aim for this the study shows the analysis of tissue reaction due to implantation of Nanocomposite and Giomers. The subcutaneous tissue of a mouse is substituted with the human gum tissues. In the experimental group, Nanocomposite and Giomers were implanted in the subcutaneous tissue abdomen region in mice. The slides were made from the surrounding of implantation for both experimental and control groups. The evaluation of the effects of the implant is done in a time interval. Evaluated time intervals are 24 hours, 7" day, 14th day, 21st day and 28th day respectively. The amounts of inflammatory cells formation in both groups were compared.Once the results of the inflammatory cells are evaluated in the given time interval for Nanocomposite, Giomer, and control group then they are statistically analyzed. The statistics used in the experiments is Mann-Whitney and Wilcoxon. The conclusion of this research showed that statistically significant differences on lymphocytes value between treatment and control group.

Kejahatan perdagangan orang (human trafficking) adalah kejahatan kemanusiaan yang terorganisasi, artinya kejahatan ini melibatkan beberapa orang yang memiliki jaringan atau keterkaitan satu sama lain dan memiliki tujuan untuk mengeksploitasi korban demi keuntungan sepihak (pelaku). Dalam kurun waktu 2005-2009, Jawa Barat menduduki peringkat teratas kasus human trafficking. Salah satu daerah di Provinsi Jawa Barat yang merupakan daerah rentan menghadapi permasalahan tindak human trafficking adalah Kabupaten Indramayu. Berbagai data menyebutkan bahwa kasus human trafiking di Kabupaten Indramayu selalu mengalami peningkatan setiap tahunnya. Penelitian kali ini mencoba menghadirkan hal-hal yang telah dan akan dilakukan oleh stakeholder di Kabupaten Indramayu dalam meminimalisasi tingkat tindak human traffickinggb777
