This study evaluated, in vitro, marginal microleakage in class II restorations confected with the glass ionomer cement Vitremer and with the composite resins Ariston pHc and P-60. The aims of the study were to assess the effect of thermocycling on those materials and to evaluate two methods utilized in the analysis of dye penetration. Sixty premolars divided in three groups were utilized; the teeth had proximal cavities whose cervical walls were located 1 mm below the cementoenamel junction. Half of the test specimens from each group underwent thermocycling; the other half remained in deionized water, at 37ºC. The specimens were immersed, for 24 hours, in a basic 0.5% fuchsin solution at 37ºC. For the analysis of microleakage, the specimens were sectioned in a mesio-distal direction, and the observation was carried out with the software Imagetools. The results were evaluated through the 2-way ANOVA and through the Tukey’s test. All groups presented marginal microleakage. The smallest values were obtained with Vitremer, followed by those obtained with the composite resins P-60 and Ariston pHc. There was no statistically significant difference caused by thermocycling, and the method of maximum infiltration was the best for detecting the extension of microleakage.

This study aimed to examine the marginal seal between various commercial temporary restorative materials and exposed dentin/built-up composite. Sixty bovine incisors were cut above the cemento-enamel junction, and half of the dentin was removed to form a step, which was built up using flowable resin composite. The root canals were irrigated, filled with calcium hydroxide, and sealed using one of six temporary sealing materials (hydraulic temporary restorative material, temporary stopping material, zinc oxide eugenol cement, glass-ionomer cement, auto-cured resin-based temporary restorative material, and light-cured resin-based temporary restorative material) (n = 10 for each material). The samples were thermocycled 500 times and immersed in an aqueous solution of methylene blue. After 2 days, they were cut along the long axis of the tooth and the depth of dye penetration was measured at the dentin side and the built-up composite side. For the margins of the pre-endodontic resin composite build-up, the two resin-based temporary restorative materials showed excellent sealing. Hydraulic temporary restorative material had a moderate sealing effect, but the sealing effect of both zinc oxide eugenol cement and glass-ionomer cement was poorer.

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 (p<0,05). 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.
