摘要：Modern dental restoration materials fulfil all the physical, biocompatibility and aestheticsrequirements but they do not possess antibacterial activity to protect the tooth from recurrent caries. In this direction,many researchers worked on incorporation of different antibacterial agents like silver, antibiotics, Zinc oxide etc, indental filling materials. The objective of present research work was to conduct the green synthesis of silvernanoparticles using Azadirachta indica extract and to incorporate these into dental filling material to conferantibacterial activity to the dental filling material. In order to fulfil the objective of this work, various experimentalparameters of the process of green synthesis of silver nanoparticles were optimized. The SNPs were then characterizedusing UV-Vis spectrophotometer, particle size analyser, FTIR spectrophotometer. Their antibacterial activity wasconfirmed using agar diffusion test against E.coli and S.mutans. The silver nanoparticles were then incorporated intoGlass Ionomer Cement (Fuji II) and the antimicrobial test conducted using S.mutans and the results indicated theincrease antimicrobial property. The novel material is not soluble in the common beverages like tea, coffee, coca colaand lime juice.
