1 bulan di dalam inkubator dengan suhu 37°c kemudian direndam di dalam larutan methylene blue 5% selama 24 jam, selanjutnya diamati dengan sem. hasil analisa deskriptif menunjukkan bahwa terdapat jarak antara bahan penutupan pit dan fisuradan permukaan gigi di bawah gambaran sem, dengan rerata jarak bahan berbasis resin komposit dan permukaan gigi setelah aplikasi 24 jam yaitu 1,79 ± 0,026 µm dan setelah aplikasi 1 bulan yaitu 1,37 ± 0,004 µm sedangkan pada bahan glass ionomer cement (gic) setelah aplikasi 24 jam yaitu 33,37 ± 1,520 µm dan setelah aplikasi 1 bulan yaitu 3,69 ± 0,710 µm. kesimpulan penelitian ini adalah terdapat perbedaan nilai rerata jarak adaptasi marginal bahan penutupan pit dan fisura berbasis resin komposit dan gic, yaitu rerata jarak adaptasi marginal lebih kecil setelah aplikasi 1 bulan daripada 24 jam pada kedua bahan. kata kunci: bahan penutupan pit dan fisura, adaptasi marginal, dan scanning electron microscope (sem). abstract name : misra hanum study program : dentist education faculty : dentistry tittle : evaluation of pit and fissure sealant marginal adaptation under scanning electron microscope (sem) image pit and fissure are varies in shape and depth. tooth with deep and narrow pit and fissure are susceptible for food and baterial retention that leads to caries formations, so it needs prevention treatment with more effective method such pit and fissure sealant. this study aimed to obtain information about marginal adaptation as mean value of distance between enamel surface and pit and fissure sealant after 24 hours and 1 month application by using scanning electron microscope (sem). samples were 4 maxillary premolars with deep and narrow pit and fissure which were applied composite resin (3m espe clinpro) and gic (fuji vii) as sealants. specimens were stored for 24 hours and 1 month in incubator with temperature of 37°c and were immersed in 5% methylene blue solution for 24 hours, then were observed under sem. descriptive analysis showed there was distance between enamel surface and pit and fissure sealants with resin based were 1.79 ± 0.026 µm after 24 hours application and 1.37 ± 0.004 µm after 1 month application while on gic based were 33.37 ± 1.520 µm after 24 hours application and 3.6925 ± 0.710 µm after 1 month application. conclusion of this study, there were a difference mean value of distance between enamel surface and sealants composite resin and gic based, where smaller distance was showed after 1 month application than 24 hours application. keywords: pit and fissure sealants, marginal adaptation, and scanning electron microscope
