The present book discusses green method for synthesis of silver nanoparticles exploiting the potential of plants. The synthesis is followed by evaluation of their antibacterial and antifungal properties.. Owing to their great antimicrobial activities and promising results, these synthesized nanoparticles can be used in various dental applications. The potential of nanoparticles to control the formation of biofilms within the oral cavity and oral infection can also be investigated in near future. This book abundantly uses images of various stages along with detailed protocols and compositions of all the reagents. . This book will open new vistas for green synthesis of nanoparticles using plant extracts and their potential use in dentistry.
