Bukhari, Jaffar Hussain published the artcileLow-temperature flow-synthesis-assisted urethane-grafted zinc oxide-based dental composites: physical, mechanical, and antibacterial responses, Recommanded Product: Ethyl 4-dimethylaminobenzoate, the publication is Journal of Materials Science: Materials in Medicine (2021), 32(8), 87, database is CAplus and MEDLINE.
A novel way was adopted to graft zinc oxide (ZnO) with urethane-modified dimethacrylate (UDMA) in order to utilize them as reinforcing agents in resin-based dental composites. Exptl. novel composites were synthesized having UDMA-grafted and nongrafted ZnO, at a concentration of 0 weight%, 5 weight%, and 10 weight%. The same concentrations of ZnO were also incorporated in Filtek Z250 XT (3 M ESPE, USA). The antibacterial behavior was evaluated against Streptococcus mutans by direct-contact test at one, three, and seven days of incubation. The compressive strength and Vickers microhardness were tested as per ISO 9917 and ISO/CD6507-1, resp. For abrasive wear resistance, mass loss and roughness average after tooth-brushing cycles of 24,000 at custom-made tooth-brushing simulator were evaluated using noncontact profilometer. Data anal. was carried out using post hoc Tucky′ s test and nonparametric Kruskal-Wallis test. Direct contact test revealed that the antibacterial potential of novel and com. composites was increased with an increase in the concentration of grafted ZnO as compared with nongrafted, whereby the potential was the highest at day seven. There was a significant decrease in compressive strength and Vickers hardness of com. composites on addition of grafted ZnO while there was no significant difference in the strength of exptl. novel composite. The abrasive wear of com. and exptl. composites was within clin. limits. Low-temperature flow-synthesis method was successfully employed to synthesize grafted and nongrafted ZnO. The UDMA-grafted ZnO can be incorporated into dental composites without decreasing their strength and these composites can be used to combat secondary caries.
