S Salah satu masalah utama dalam keberhasilan suatu restorasi resin komposit adalah kebocoran mikro. Kebocoran mikro seringkali dijumpai terutama pada kavitas kelas V karena adanya perbedaan struktur morfologis dan histologis antara email dan dentin / sementum, yang mempengaruhi daya perlekatan resin komposit. Pengaplikasian bahan pelapis pada permukaan restorasi merupakan salah satu upaya mengurangi terjadinya kebocoran mikro. Material yang dapat digunakan sebagai bahan pelapis restorasi adalah surface sealant ataupun rebonding dengan menggunakan bonding agent. Penelitian ini bertujuan untuk mengetahui perbedaan kebocoran mikro antara hasil aplikasi surface sealant dan one-step self-etch adhesive pasca penumpatan resin komposit pada kavitas kelas V. Sebanyak 21 gigi premolar RB yang telah dipilih secara acak lalu dibagi menjadi dua kelompok perlakuan masing – masing 10 sampel dan satu sampel sebagai kontrol. Kelompok I: Surface sealant (G-Coat Plus), kelompok II: One-step self-etch adhesive (OptiBondTM All-In-OneTM Kerr), dan kelompok kontrol tidak diberikan bahan pelapis. Seluruh sampel pertama – tama dipreparasi pada bagian bukal dengan ukuran 3 mm oklusogingival, 3 mm mesio-distal, dan kedalaman kavitas 1,5 mm. Setelah tahap polishing dan pengaplikasian bahan pelapis, seluruh sampel diolesi pewarna kuku pada bagian apeks dan mahkota, kecuali bagian permukaan restorasi sampai 1 mm di sekitar tepi restorasi. Sampel direndam dalam saliva buatan selama 24 jam, diikuti dengan perendaman dalam metilen biru selama 24 jam berikutnya. Gigi dipotong dalam jurusan buko-lingual lalu mengamati kedalaman penetrasi metilen biru di bawah stereo mikroskop perbesaran 20x. Analisis data menggunakan uji statistik Mann-Whitney (p<0,05). Hasil penelitian ini menunjukkan bahwa kelompok I memiliki kebocoran mikro yang lebih sedikit dibandingkan dengan kelompok II. Kesimpulan penelitian ini adalah terdapat perbedaan kebocoran mikro antara hasil aplikasi surface sealant dan one-step self-etch adhesive pasca penumpatan resin komposit pada kavitas kelas V.

M Microleakage is one of the major problems in the successful of a composite resin restoration. Microleakage is often found especially in class V cavities because of the differences in morphological and histological structures between enamel and dentin / cementum, which affect the attachment strength of composite resins. The application of coating materials to the surface of the restoration is a method to reduce the occurrence of microleakage. Materials that can be used as a coating for restoration are surface sealants or using bonding agent as rebonding. The purpose of this study is to determine the differences in microleakage between the application of surface sealant and one-step self-etch adhesive after composite resin restoration on class V cavities. Twenty-one lower premolar teeth were randomly selected and then divided into two treatment groups that consist ten samples for each group and one sample as control. Group I: Surface sealant (G-Coat Plus), group II: One-step self-adhesive (OptiBondTM All-In-OneTM Kerr), and the control group was not given any coating materials. All samples were prepared in the buccal surface with a size of 3 mm occlusal-gingival, 3 mm mesial-distal, and 1.5 mm cavity depth. After applied coating materials for all treatment groups, all samples including control group are smeared with nail coloring on the crown and apex, except the surface of the restoration until 1 mm around the restoration. Samples were then immersed in artificial saliva for 24 hours, followed by immersion in methylene blue for the next 24 hours. The teeth are cut in a buccal-lingual direction and then observed the penetration depth of methylene blue under a stereo microscope using 20x magnification. Statistical analysis using Mann-Whitney test between two treatment groups (p<0.05). The results of this study indicate that group I has less microleakage than group II. The conclusion of this study is that there are differences in microleakage between the application of surface sealants and one-step self-etch adhesive after composite resin restoration on class V cavities.
