Abstract

Exposure duration of light activated composite resin is one of the factors which influenced polimerization level. Polimerization level correlated with the evidence of microleakage . the aim of this study was to evaluate the effect of Exposure Duration Of Light Activated Towards Microleakage Of Restoration Flowable Composit Resin.The samples were made o0f light activated flow able composite resin (Tetric Flow) and the exposure duration was 20 seconds , 40 seconds, 60 seconds. Each group contained of 8 samples of flowable composite resin filling of middle third buccal surface premolar teeth , immersed in methylene blue solution, cut across linguo-buccal and subsequently observed on its edge microleakage using binoculer microscope indicated with the depth of methylene blue penetration. The result showed that edge microleakage from the lowest up to the highest were 40 seconds,60 seconds, 20 seconds. Mann Whitney U statistical analysis only showed significant differences among the 20 seconds group towards 40 seconds group.

Abstract

Teeth with pulp necrosis, whether or not with periapical abnormalities, may be indicated for root canal treatment. Root canal treatment is a treatment carried out with the aim of removing infected dental pulp tissue, necrotic debris, and microorganisms. It aims to make the root canal sterile and can be filled with filling material so that a hermetic density is obtained in the apical area. Root canal treatment consists of three main stages (Triad Endodontics). The endodontic triad consists of preparation, sterilization and root canal filling. These three stages of root canal treatment are very important because not all root canal treatments end with success. The success of root canal treatment can be evaluated after a minimum of six months. Subjective, objective and radiographic examinations need to be conduct for determining the success of the treatment. Root canal treatment is said to be successful if the results of the three examinations are declared good. This type of research is descriptive research. The research method was carried out by subjective, objective and radiographic examination in the study sample who had performed root canal treatment in 2016 that met the criteria of the researcher. The results of the research are included in the table and interpreted with a percentage that is very low to very good. Based on this, it was concluded that the success rate of root canal treatment in non-vital teeth at RSGM University of Jember in 2016 was 54.54% and included in the sufficient category.

Abstract

Resin komposit adalah salah satu jenis bahan tumpatan gigi anterior yang populer karena memiliki kelebihan dalam bidang estetik dan sewarna gigi. Komposit nanofiller memiliki sifat mekanik lebih baik dibandingkan microhybrid dan dapat mempertahankan kehalusan selama pemakaian setara microfiller. Resin komposit dapat mengalami perubahan warna di dalam rongga mulut, salah satunya dapat disebabkan oleh minuman dengan pH rendah. Tujuan penelitian adalah mengetahui adanya pengaruh perendaman di dalam minuman susu fermentasi terhadap perubahan warna resin komposit nanofiller. Selain itu untuk mengetahui adanya perbedaan perubahan warna resin komposit nanofiller selama perendaman 6, 12, dan 18 jam. Jenis penelitian yang digunakan adalah eksperimental laboratories dengan rancangan penelitian desain grup pretest and post test. Sampel berjumlah 24 direndam dalam susu fermentasi selama 6, 12, dan 18 jam. Pengukuran perubahan warna menggunakan spektrofotometer optik untuk mengetahui nilai intensitas cahaya. Nilai perubahan warna tampak pada besarnya nilai intensitas cahaya yang muncul pada alat spektrofotometer optik.  Analisis data menggunakan uji Paired-T Test dan One Way Annova. Nilai uji intensitas cahaya  sesudah perlakuan lebih tinggi dari sebelum perlakuan. Selisih rata-rata nilai uji intensitas cahaya sebelum dan setellah perlakuan paling tinggi pada perendaman 18 jam dan paling rendah pada perendaman 6 jam. Resin komposit nanofiller mengalami perubahan warna setelah dilakukan perendaman dalam minuman susu fermentasi dengan perbedaan yang signifikan. Kata kunci: Resin Komposit, Perubahan Warna, Estetik, Susu Fermentasi, Nanofiller
