Preparation and Characterization of Dental Pit and Fissure Sealant Based on Calcium Sodium Silicate Bioactive Glasses

Abstract: This study aimed to prepare a resin based dental sealant loaded with novel bioactive glass formulated from (50 wt% calcium silicate and 50 wt% sodium silicate) with different percentages of fluorapatite. Four glass batches were formulated then characterized using Fourier Transform Infrared Spectroscopy analysis, X-ray powder diffraction analysis and Transmission electron microscopy. Density, microhardness and bioactivity testing after insertion in artificial saliva were done. Four bisphenol A-glycidyl methacry… Show more

“…However, different conclusions were reached by Chen, et al [35], who studied the influence of osteoblast cell cultures (MC3T3) on cell line 58S glass (60% SiO 2 , 36% CaO, 4% P 2 O 5 ). In this case, the survival rate of cells in direct contact was 78% [35,36]. The bioactive material consisting of acrylic resin and containing 3% Novaron bioceramics, according to the authors of Chen, et al [35], is not cytotoxic.…”

“…Silane coupling agent was prepared by proportioning 70 wt.% ethanol in a glass beaker, a few drops of acetic acid were then added gradually into the solution to decrease the pH to 3–4. Finally 6 wt.% trimethoxysilane was added 11 , 35 . Stirring was done using a magnetic stirrer for 1 h. The silica nanoparticles synthesized from rice husk were incubated in the silane coupling agent for 2 h and then centrifuged (Megafuge 8R, Thermo Fisher, Germany) for 30 min.…”

“…Five cured cylindrical specimens with dimensions of 4 mm in diameter and 6 mm in height were prepared as previously mentioned. The specimens were then immersed in a freshly prepared artificial saliva (2.38 g Na 2 HPO 4 , 0.19 g KH 2 PO 4, and 8.00 g NaCl per liter of distilled water adjusted with phosphoric acid to pH 6.75) 35 and stored at 37 °C for 1, 7 and 14 days. The volume of the artificial saliva was adjusted to be 10 mm 3 according to the equation Vs = Sa/10, where Vs is the volume of the artificial saliva, and Sa is the apparent surface area of each specimen 41 .…”
