What is Maxillary Anterior Teeth With Extensive Root Resorption Treated With Low-level Light-activated Engineered Chitosan Nanoparticles about?

## Introduction: Photoactivated chitosan-based nanoparticles can eliminate bacterial biofilm, inactivate endotoxins, improve resistance to biological degradation (resorption), and promote bone regeneration. this case is the first documentation to highlight the successful healing of teeth with extensive inflammatory root resorption (irr) with periapical lesions using a combined surgical and nonsurgical root canal therapy using rose bengal functionalized chitosan nanoparticles (csrbnp). ## Methods: A 17-year-old boy with extensive irr of maxillary right canine (teeth #6), maxillary right lateral incisor (#7), maxillary right central incisor (#8), and maxillary left central incisor (#9) was treated with photoactivated csrbnp, both intracanal as well as topically on resorptive defects and periapical lesions. the larger external resorptive defects on the root surfaces were restored with biodentine, whereas the through-and-through periapical lesions were packed with sticky bone for guided bone regeneration. ## Results: At 26 months of follow-up, the clinical, 2-dimensional (intraoral periapical radiographs) and 3-dimensional (cone-beam computed tomography) images showed absence of clinic
