Nanozymes in Endodontics

Summary

The antimicrobial efficacy and healing potential of clinically approved ferumoxytol nanozymes versus the standard 3% NaOCl irrigant will be evaluated in adults undergoing endodontic treatment. Building on prior protocols that demonstrated ferumoxytol nanozymes antimicrobial activity as a root canal irrigant, ferumoxytol solution will be applied topically, assessment of clinical and radiographical findings will determine its potential as a novel disinfection and its long-term outcome.
