Abstract

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.

Abstract

Resin akrilik (PMMA) heat-cure umumnya digunakan dalam bidang kedokteran gigi, satu diantaranya adal mahkota jaket akrilik. Salah satu sifat dari resin akrilik yangs erring menjadi masalah adalah buruknya resistensi penggunaan yang menghadilkan durabilitas yang rendah, ini dkarernakan kekerasan akrilik lebih rendah dibandingkan bahan restiratif lain. Maka, untuk meningkatkan kekerasanya, partikel bahan pengisi inorganic dapat ditambahkan. Salah satu bahan inorganic yang melimpah di Indonesia, disebut kaolin yang mengandung partikel kaolinit yang tidak bisa secara mudah dipecahkan dan dipisahkan sehingga kaolinit dapat membentuk pertahanan yang tidka mudah didegradasi. Tujuan dari penelitian ini adalah untuk menambah partikel bahan pengisi kaolin pada resin akrilik heat-cured da menghitung kekerasannya. Bubuk metakaolin yang digunakan padapenelitian ini dibuat dari bubuk kaolin yang terkalsinasi dengan tigarasio berbeda (setiap kelompok terdiri dari 5 spesimen) dan kemudia kekerasan dari setiap kelompok diuji menggunakan metode uji micro-vickers, kemudian satu kelompok yang memiliki hasil paling baik diuji dengan Scanning Electron Microscope untuk melihat distribusi bahan pengisi. Hasilnya adalah kekerasan resin akrilik meningkat secara proposional dengan peningkatan jumlah bahan pengisi, dimana peningkatan paling signifikan didapat dari kelompok dengan bahan pengisi kaolin 50% dimana distribusi bahan pengisi terlihat homogen setelah dilakukan analisa foto SEM dari komposit yang dibuat. Bahan pengisi kaolin dapat digunakan sebagai bahan pengisi resin akrilik untuk meningkatkan sifat kekerasan resin komposit.

Abstract

Impression taking is performed to find model of patient’s teeth and oral cavity in making restoration or orthodontic appliances. The impression enable bacteria, fungi or virus from saliva or blood in oral cavity to be transferred. Washing the impression by using running water is not enough to completely remove all of bacteria, fungi or virus has been attached on the impression. Therefore the disinfection procedure on impression is needed to avoid the cross infection between the patient and operator. Cross infection of contamination of virus, fungi or bacteria cause of B hepatitis, tuberculosis, herpes zoster and Human Immunodeficiency Virus-Acquired Immune Deficiency Syndrome (HIV-AIDS) diseases. There are many many disinfectant agents which have been recommended to be used in effort to disinfect impression such as chlorine compound, iodophore, glutaraldehide and phenol. There are several methods of disinfection can be performed such as immersion, spray or admix the disinfectant into impression material. However several disinfection methods cause side effects such as dimensional change especially on alginate impression, quality of impression surface, surface roughness and other properties of impression material. In this paper the side effects occur in impression material caused by impression disinfection will be studied and discussed. Farther the disinfection by using UV light, blue light, microwave, autoclave, gargle and the possibility of traditional flora solution using as disinfectant of impression will be explained.

Abstract

Synthetic bone graft material was developed as a scaffold that serves to template the formation of bone. The ideal scaffold should be biodegradable, osteoindukctive, and osteoconductive. Silica proven to support and promote bone growth. Rice husk contains silica is quite high. The purpose of this study is to analyze the amorphous silica from rice husk as synthetic bone graft material (scaffold), particularly on osteoblast activity in vitro. The research was conducted by isolating silica from rice husk.The results of isolation would be conditioned on the culture medium of primary osteoblasts. Primary osteoblast cultures derived from rat calvaria wistar age of 2 days, growing in Alpha-Modified Eagle Medium (α-MEM) (as a negative control), α-MEM in conditioning with silica 58s (as a positive control) and α-MEM that conditioned with silica from rice husk (as treatment group). Osteoblast activity was observed by analyzing the expression of alkaline phosphatase, using Alkaline phosphatase Kits at days 7 and 14. The results obtained that the rice husk silica were significantly (p <0.05) has the expression of alkaline phosphatase higher than the control group and potitif group. This may imply that the amorphous silica of rice husk affects the increase in osteoblast activity in vitro. It was concluded that rice husk silica increases osteoblast cell activity that is potentially as scaffold for bone graft synthetic material.

Abstract

Resin modified glass ionomer cements (RMGIC) is a restorative dental material developed in 1967. The surface roughness of this restorative materials cause plaque accumulation which lead to quality degradation and brittleness of restoration. The aim of this research is to determine the effect of infused water immersion with brushing against the surface roughness changes of RMGIC. Forty samples (6mm diameter, 4mm thickness) were divided into 4 groups: group A light-cured RMGIC and group B self-cured RMGIC were soaked in 100mL of mineral water for 15 days, group C light-cured RMGIC and group D self-cured RMGIC were soaked in 100Ml infused water for 5 minutes and replaced by mineral water for 5 minutes repeated 20 times each day in 15 days. The samples were brushed for 2 minutes before and after immersion. Samples roughness were tested before and after treatment using a surface roughness tester. The surface roughness of group A was 1,28±0,49µm (before) 3.24±1.18µm (after), group B 0.52±0.23µm (before) 2.76±0.55µm (after), group C 1.87±0.45µm (before) 4.26±2.36µm (after), and group D 0.88±0.53µm (before) 4.01±1.09µm (after). Statistical analytics using t-test showed a significant difference in surface roughness value between before and after treatment, but no significant difference in the increase value of roughness after soaked in infused water between self-curing and light-curing RMGIC.
