Evaluation of antimicrobial property of self etch adhesive incorporated with green synthesized tio2 nanoparticles: An invitro study

Since its introduction about fifty years ago, adhesive technology has advanced rapidly. In this current era,nanoparticles has gained attention in restorative dentistry because of its advantages like improving bond strength and stability of restoration.As opposed to the chemical process, the green synthesis of titanium oxide nanoparticles has more advantages one of which is improved antimicrobial activity. Antibacterial  dental adhesives can help to prevent recurrent or secondary caries. The aim of this invitro study was to evaluate the antimicrobial property of self etch adhesives incorporated with Tio2 nanoparticles. The extracts of Piper longum herb was used to make titanium dioxide nanoparticles (TiO2NPs) in a green way.Its aim is to create a tight bond between tooth dentin and restorative material.Failures in this process could result in microleakage, allowing bacteria, fluids, and ions to infiltrate.The antimicrobial property of self etch adhesives incorporated with Tio2 nanoparticles were tested against standard strain of S.mutans, lactobacillus and E.faecalis using the Zone of inhibition test. The diameter of inhibition zones were measured in millimeters
