Comparative evaluation of antimicrobial properties of silver nanoparticles and chlorhexidine mouthwashes on the colonization of microflora and oral health during orthodontic treatment: a double-blind randomized controlled trial

Although SNP mouthwash was effective in the reduction of all the assessed parameters, it could not decrease them to the baseline levels, suggesting its limited efficacy. CHX mouthwash proved to be extremely effective by decreasing the microbial count, plaque index and gingival index below the baseline level.
