<![CDATA[Penutupan fisura merupakan metode pencegahan non-invasif yang efektif pada permukaaan gigi dengan pit dan fisura yang dalam dan sempit untuk mencegah terjadinya karies. Bahan penutupan fisura yang sering digunakan adalah resin komposit dan Glass Ionomer Cement (GIC). Penelitian ini bertujuan untuk mendapatkan informasi tentang perbandingan tingkat kebocoran mikro antara resin komposit dan GIC sebagai bahan penutupan fisura melalui evaluasi in vitro setelah satu bulan aplikasi. Spesimen penelitian berjumlah 16 gigi premolar rahang atas dengan pit dan fisura yang dalam dan sempit. Spesimen ini dikelompokkan menjadi 2 kelompok perlakuan. Kelompok pertama menggunakan resin komposit (3M ESPE Clinpro) dan kelompok kedua menggunakan GIC (Fuji VII). Spesimen dilakukan pengkondisian selama satu bulan didalam inkubator dan direndam dalam larutan methilene blue 5% selama 24 jam. Spesimen kemudian diamati dengan menggunakan stereo mikroskop dan diukur tingkat kebocorannya. Skor kebocoran mikro menggunakan penetrasi dye dengan tiga kriteria skor yaitu 0, 1, dan 2. Data dianalisis menggunakan statistik nonparametrik (uji Mann Whitney). Hasil analisis menunjukkan terdapat perbedaan skor kebocoran mikro yang signifikan antara bahan penutupan fisura resin komposit dan GIC (p0,05). Kelompok penutupan fisura dengan resin komposit memiliki rerata skor kebocoran mikro lebih kecil (0,25) dibandingkan kelompok penutupan fisura dengan GIC (1,875) setelah penutupan fisura satu bulan.]]>

<![CDATA[Resin komposit nanofiler merupakan restorasi estetik di bidang kedokteran gigi dengan kelemahan dapat menyerap cairan di sekitar permukaannya. Kopi arabika gayo merupakan salah satu kopi arabika unggulan di Aceh. Minuman kopi memiliki pH rendah (asam) yang dapat menyebabkan degradasi ikatan polimer dan partikel filer. Tujuan penelitian ini adalah untuk melihat perubahan mikrostruktur permukaan resin komposit nanofiler sebelum dan setelah perendaman dalam kopi arabika gayo selama 4 dan 6 hari. Penelitian ini menggunakan metode eksperimental laboratoris dengan rancangan pretest + posttest design group. Terdapat 4 spesimen resin komposit nanofiler yang berbentuk silinder dengan tebal 2 mm dan diameter 6 mm, dan dibagi dalam 2 kelompok yakni kelompok A berjumlah 2 spesimen (A1A2) yang direndam dalam minuman kopi arabika gayo selama 4 hari dan kelompok B berjumlah 2 spesimen (B1B2) direndam dalam kopi arabika gayo selama 6 hari. Mikrostruktur specimen diamati perubahannya dengan menggunakan scanning electron mcroscope (SEM) dengan perbesaran 3000x. Hasinya, terlihat area yang berwarna gelap/porus pada gambaran SEM. Setelah dianalisis dengan paired t-test dan unpaired t-test (p0,05) terdapat perbedaan yang bermakna antara kelompok A dan kelompok B. Kesimpulan: Semakin lama perendaman yang dilakukan semakin jelas terlihat perubahan yang terjadi.]]>

<![CDATA[Glass Ionomer Cement (GIC) Conventional dan Resin Modified Glass Ionomer Cement (RMGIC) merupakan material kedokteran gigi yang sering digunakan sebagai basis pada restorasi resin komposit. Penggunaan basis di bawah restorasi resin komposit dikenal dengan teknik sandwich. Restorasi dengan menggunakan teknik sandwich dapat mengurangi terjadinya kebocoran mikro pada restorasi resin komposit. Tujuan dari penelitian ini adalah untuk mengetahui perbandingan kebocoran mikro antara basis GIC Conventional dan RMGIC pada restorasi resin komposit nanofiller dengan teknik sandwich. Penelitian ini menggunakan 20 spesimen gigi premolar dengan kavitas klas 1 kemudian direstorasi dengan teknik sandwich, lalu dibagi menjadi dua kelompok perlakuan. Kelompok A adalah teknik sandwich yang menggunakan resin komposit nanofiller dengan basis GIC Conventional dan kelompok B adalah teknik sandwich yang menggunakan resin komposit nanofiller dengan basis RMGIC. Seluruh spesimen direndam dalam larutan pewarna biru metilen selama 24 jam kemudian dilakukan pengamatan untuk pengukuran skor kebocoran mikro dengan menggunakan stereomikroskop. Hasil penelitian menunjukkan bahwa basis GIC Conventional memiliki rerata skor kebocoran mikro sebesar 0,20 0,422 dan basis RMGIC 0,00 0,00. Sedangkan hasil penelitian pada teknik sandwich kelompok A (nanofiller dan GIC konventional) menunjukkan rerata skor kebocoran mikro sebesar 0,600,843 dan kelompok B (nanofiller dan RMGIC) sebesar 0,300,483. Hasil uji statistik non parametrik Mann Whitney antara basis GIC Conventional dan RMGIC serta antara kelompok A dan B menunjukkan perbedaan yang tidak bermakna (p 0,05). Dari hasil penelitian dapat disimpulkan bahwa terdapat perbedaan kebocoran mikro yang tidak bermakna pada kelompok teknik sandwich dengan basis GIC Conventional dan basis RMGIC.]]>

<![CDATA[Microleakage is a gap that allow clinically undetectable passage of bacteria, fluids, chemical substances between the tooth and its restoration. Microleakage can occurs whether in a cavity restored with Glass Ionomer Cement or Alkasite. The objective of this study is to compare the microleakage between GIC and Alkasite after 1 day, 7 days and 30 days polymerization. This study used 30 specimens divided into six groups. Group A is restored with GIC and Group B restored with Alkasite. Group A1 and B1 restored and conditioned in incubator for 1 day, group A2 and B2 for 7 days, group A3 and B3 for 30 days. The specimens isolated using varnish nail except the restored area and immersed in methylene blue 1% for 1 day, then all specimens were washed and cut longitudinally. The results were observed using a stereomicroscope. The observation results analyzed using nonparametric test Kruskal-Walis test, showed theres no significant difference in each material with differentconditioning times (p 0.05). Post hoc test using Mann-Whitney likewise, showed no significant difference between GIC and Alkasite with similar conditioning time. Descriptive statistics showed that all the mean of microleakage in GIC is bigger than Alkasite and microleakage mean score in both materials conditioned for 30 days in incubator is smaller than conditioned for 1 day and 7 days. This study concluded that microleakage in Alkasite is smaller than Glass Ionomer CementKEYWORDS: Microleakage, Glass Ionomer Cement, Alkasite, Class I]]>

<![CDATA[Microleakage is a poor marginal adaptation of the restoration, often found between cavity and restoration material. One of the reasons is the shrinkage during the composite resin during polymerization, causing the restorations adaption disturbed. Application of adhesive material on the cavity affects microleakage at the margin restoration and increases the adaptation between cavity and restoration material. This research aims to determine microleakage in dental enamel using nanofiller composite resin restoration with fifth-generation total-etch adhesive and eight-generation self-etch adhesive. This research used 16 specimens premolars, which were prepared cavity Class I G.V. Black and divided into two groups (group A and B). Group A used nanofiller composite resin FiltekTM Z350 + fifth-generation total-etch Adper Single Bond 2 (n=8), group B used nanofiller composite resin Filtek TM Z350 + eight-generation self-etch Universal Single Bond Adper (n=8). The specimen isolated using nail polish except in the work area.,then immersed in methylene blue 1% at 25C (for 24 hours). After that, all specimens were washed and cut longitudinally. The results were observed using a Stereomicroscope and Scanning Electron Microscope (SEM). The observations results showed that the amount number of microleakage in group A (75%) less than in group B (100%), while the non-parametric statistic test using the Mann Whitney showed no significant differences (p0.143). Based on SEM images, the average distance between enamel and composite resin with total-etch adhesive was 1.40 0.007m, and 1.84 0.509 m for resin composite with self-etch adhesive. This research concluded that microleakage using nanofiller composite with the fifth-generation total-etch adhesive was smaller than nanofiller composite resin with the eighth -generation self-etch adhesive.KEYWORDS: Adhesive system, nanofillers composite resin, microleakage, enamel]]>

<![CDATA[Heat-cured acrylic resin is the most common material used as denture base. Nowdays, thermoplastic nylon is also used as denture base material. One of the mechanical properties considered in the selection of denture base material is flexural strength. Flexural strength is affected by the absorption acid-containing fluid by the denture base material. Ulee Kareng coffee (coffea robusta) is a beverage that can be absorbed by the heat-cured acrylic resin and nylon thermoplastic and has acid content. The aim of this study is to observe the flexural strength of heat-cured acrylic resin and nylon thermoplastic after being immersed in Ulee Kareng coffee (Coffea robusta) for 7 days. This study is a laboratory experimental research with post-test only group design. The size of specimens were 60x10x2 mm and the total number of specimens were 16 which then divided into two groups. Group 1 consisted of 8 specimens of heat-cured acrylic resin (Meliodent) and group 2 consisted of 8 specimens of nylon thermoplastic (BIO TONE). After immersed in Ulee Kareng coffee (Coffea robusta), all specimens were tested for their flexural strength using Universal Testing Machine. The datas were analysed using unpaired t-test with significant p value of 0,05. Statistical analysis showed that the differences in flexural strength value were significant between heat-cured acrylic resin and nylon thermoplastic after being immersed in Ulee Kareng coffee (Coffea robusta). The conclusion of this study after being immersed in Ulee Kareng coffee (Coffea robusta), the flexural strength of thermoplastic nylon is higher than the flexural strength of heat-cured acrylic resin.Keywords : flexural strength, heat-cured acrylic resin, nylon thermoplastic, Ulee Kareng coffee (Coffea robusta)]]>
