Padjadjaran Journal of Dentistry or known as PJD, is an English-language scientific periodicals published by the Faculty of Dentistry Universitas Padjadjaran thrice a year on every March, July and November. The submission process of manuscript is open throughout the year. All submitted manuscripts will go through the double-blind peer review and editorial review before being granted with acceptance for publication. Designed as a medium of information and scientific knowledge, Padjadjaran Journal of Dentistry publishes numerous research articles, in the area of Oral Biology, Dental Material Science and Technology, Oral and Maxillofacial Surgery, Pedodontics, Dental Public Health and Community Dentistry, Conservative Dentistry, Periodontics, Prosthodontics, Orthodontics, Oral Medicine, Dental Radiology, as well as with their development through interdisciplinary and multidisciplinary approach. Initially published as Padjadjaran Journal of Dentistry (PJD) magazine ISSN 1979-0201(print) on 2007 in form of printed issues. In 2017, the magazine had its online published version under the same with ISSN 2549-6212 (online) in accordance with the policy of LIPI. Padjadjaran Journal of Dentistry has been using Open Journal System requiring all writers to register in advance before they are allowed to upload the manuscript they write online. Afterwards, the editors, peer reviewers, and writers can monitor the manuscript processing. Several other changes are informed in the Journal History.

Abstract

Introduction: Several factor limits of services of dental composite have triggered further improvement. ZrO2-Al2O3-SiO2 system as filler of dental composite had been developed with sol-gel technique. Ultrasonic homogeniser were reported to change the particle size ditribution or shape. Unifom size and distribution of particle is believed to help define the behavior of hardness properties. Methods: The study was an laboratory experimental design. Filler ZrO2-Al2O3-SiO2 system were developed via sol-gel methods. Post calcination process, filler were immerse in ethanol and applied with ultrasonic homogeniser, with various amplitude i.e 50 rpm, 60 rpm and 80 rpm then named sample A, B, and C. XRD, SEM anda PSA were used to characterize of filler system. Subsequent filler were used to fabricate dental composite then evaluate the hardness value using micro-hardness tester. One–way ANOVA was used to analysis the statistical result of hardness value. Results: XRD pattern of three sample were similar in which tetragonal zirconia was prominent (57-61 %) followed by monoclinic zirconia (24-25%) and amorphous (15-17 %). While, SEM and PSA characterization showed amplitude 50 rpm (sample A) produce more uniform size and well-distributed particle filler than the others. In contrary, sample B and C showed higher peak in PSA results. It means there was dominating of filler with particular size.  However, the hardness value did not show significant differences between those filler (p>0,05). Conclusion: Dental composite that contain of different uniformity and distribution of filler ZrO2-Al2O3-SiO2 system has no significantly differences of hardness value.

Abstract

Introduction: Caries are initiated by the plaque formation on the tooth surface, due to the interaction between food debris and bacteria in the mouth. The pioneer bacterium of plaque formation is Streptococcus sanguis. The  Strawberry fruit, lime fruit, and radish root are part of the plant that contains antibacterial substances. Flavonoid, tannin, saponin, alkaloid, polyphenol, terpenoid and quinon as antibacterial substances. This study aimed to evaluate strawberry fruit, lime fruit, and radish root methanol extract can inhibit Streptococcus sanguis ATCC 10556. Therefore, strawberry, lime, and radish can be made into mouthwash, bubble gum, or toothpaste to prevent plaque formation. Methods: This study used a Kirby-Bauer diffusion test as the inhibition test. Results: The result of this study that the biggest inhibition zone was lime methanol extract 20,000 ppm, and the smallest one was radish methanol extract 5,000 ppm.  Conclusion: Strawberry fruit, lime fruit peel, and radish root methanol extract and their combination had the effect of inhibiting bacterial growth synergistically against Streptococcus sanguis ATCC 10556.
