Introduction: This study aimed to evaluate the antibacterial and antifungal effect of Ag and zinc oxide nanoparticles to complete denture acrylic resin. Materials & Methods: In this experimental laboratory study, 144 samples were evaluated. The powder of acrylic resin (PMMA Ivoclar Vivadent, Lichenstein SR Triplex Hot) was mixed homogeneously in the ultrasonic apparatus with Ag (purity: 99.99%, size: 20nm, spherical) and ZnO (purity: 99%, size: 10-30 nm, nearly spherical) particles with mass fraction 0.5, 1 ,2 and 5. The microorganisms of this study were Candida albicans and Streptococcus mutans. The growth rate of microorganisms was measured by spectrophotometer based on turbidity and readings at 600 nm. Data were analyzed by ANOVA and Tukey post hoc tests. The significance level was set at 0.05. Results: Increasing Ag and ZnO nanoparticles to acrylic resin reduced the growth of Candida Albicans and Streptococcus Mutans. Even the concentration of 0.5% significantly reduced the growth of microorganisms. Complete growth inhibition was in the concentration of 5% after 24 and 48 hours. Conclusion: Increasing the Ag and ZnO nanoparticles to acrylic resin reduced the growth of microorganisms.

BMH is a new type of inorganic antibacterial agent. However, there is few study about BMH application in plastic film. So, in this study, BMH/PE films prepared by rolled was investigated in antimicrobial, mechanical and optical properties with different BMH contents. The results showed that the antibacterial properties increased with the BMH content, and the antibacterial films had strong antibacterial function when the adding amount of BMH was equal or greater than 2%. The mechanical properties firstly increased with the BMH content and then rapidly decreased. The optical properties decreased with BMH content. Taking all properties of the film into account in the study, the antimicrobial film contained 1% BMH was best.

Karies gigi merupakan masalah kesehatan yang umum terjadi di kalanganmasyarakat Indonesia. Faktor yang paling banyak menyebabkan karies gigi adalah plak gigi.Bakteri yang dominan dalam plak gigi adalah Streptococcus mutans. Salah satu bahanantibakteri kariogenik yang biasa dipakai dalam pasta gigi saat ini adalah fluor. Penggunaanpasta gigi berfluor dapat menimbulkan fluorosis yaitu pelemahan email gigi bila dipakaidalam konsentrasi yang berlebihan. Propolis dan garam kelapa merupakan bahan alamiyang berpotensi sebagai antibakteri pengganti fluor. Penelitian bertujuan untuk mengujiaktivitas antibakteri dari campuran propolis dan garam kelapa dan membandingkankeefektifannya dengan antibakteri NaF yang terdapat dalam pasta gigi komersial. Ujiaktivitas antibakteri S. mutans dilakukan dengan metode hitungan cawan yaitupenghitungan jumlah bakteri yang tumbuh di media contoh dalam cawan petri. Propoliskasar diekstrak dengan alkohol dan didapatkan rendemen sebesar 8.52%. Hasil penelitianmenunjukkan bahwa campuran propolis 6.25% dan garam kelapa 1 M mempunyaikemampuan paling besar sebagai antibakteri dan dapat menghambat S. mutans lebih baikdaripada NaF 0.3%. Keefektifan propolis-garam terhadap NaF 0.3% sebesar 203.88%.Kata kunci : propolis, garam kelapa, antibakteri, antikaries gigi, Streptococcus mutans,

ABSTRACTBackground: Acrylic resin artificial teeth is easily to have bacterial adhesion. It is necessary to perform a treatment on that surface, in order to reduce bacterial adhesion. This study aimed to reveal the effect of silica coating in acrylic resin artificial teeth on surface roughness, contact angle measurement, and the growth of Streptococcus mutans.Method: The study was conducted on two groups (n=16) of disk-shaped acrylic resin artificial teeth with a diameter of 10 mm and thickness of 2 mm. A 2% silica coating material was obtained by diluting 2 g silica nanoparticles on 100 ml of ethanol. Surface roughness, contact angle measurement, and the growth of Streptococcus mutans was measured using surface roughness measuring instrument, camera digital, and colony counter. The data obtained were then analyzed using T-test (p<0.05).Result: The results showed that the surface roughness and contact angle measurement in group I (0.29±0.08 μm); (79,49º ± 10,88º) was higher than group II (0.17±0.05 μm); (34,77º±0,05º). The growth of Streptococcus mutans in group I was also higher (32.28±3.75 CFU/ml) than group II (24.83±3.47 CFU/ml). Conclusion: The study concluded that there is an effect of silica coating on surface roughness, contact angle measurement, and the growth of Streptococcus mutans in acrylic resin artificial teeth.
