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

Composite restoration is frequently found on teeth before doing any bleaching treatment. Hydrogen peroxide is a bleaching agent which enable transition to one of the composite physical properties. The aim of this research was to observe the difference of surface hardness between methacrylate and silorane based composite resin after application of 40% hydrogen peroxide. This true experiment involved 36 specimens from two different disc-shaped methacrylate and silorane based composite resins, with 18 specimens methacrylate and 18 silorane. Every specimen groups were immersed in artificial saliva solution and divided into two groups; the first group consisted of 9 specimens of control which were tested directly using microvickers hardness tester and another group consisted of 9 specimens which had been added by 40% hydrogen peroxide for hardness test. The result showed the different surface hardness average value of metachrylate and silorane based composite resin after application of 40% hydrogen peroxide. The surface hardness of methacrylate and silorane based composite resins was 41.8 VHN and 33.7 VHN (p>0.05) with t-test, respectively. From this study concluded that there was no significant difference between methacrylate and silorane based composite resins after 40% hydrogen peroxide application.

Abstract

Mouthwash is widely used by the community to maintain oral health. Beside the benefit provided, both alcohol-containing mouthwash and alcohol-free mouthwash have negative effects on the composite resin restorative materials, which can affect the surface hardness. One of composite types is hybrid type which is superior in physical and mechanical properties as a restorative material. The aim of this study was to determined the effect of alcohol-containing mouthwash and alcohol-free mouthwash towards the surface hardness of hybrid composite restorative material. This study used 15 disc-shaped specimens of hybrid composite with the size of 6 mm diameter and 4 mm thickness and divided into three treatment groups immersion, in the alcohol-containing mouthwash (A), alcohol-free mouthwash (B), and artificial saliva (C) as control for 12 hours, which surface hardness was further tested using Vickers hardness test. The mean of hardness values of group: A 24.9 VHN; B: 27.2 VHN; and C: 28.4 VHN. The results of statistical tests One-Way ANOVA showed there were significant differences in the hardness values among the three treatment groups (p<0,05). From this study concluded that both alcohol-containing mouthwash and alcohol-free mouthwash were decreasing the surface hardness of hybrid composite restorative material.
