Can tiny silver particles supercharge root canal healing?

This trial tests whether adding silver nanoparticles to a standard antibiotic paste used inside root canals can better reduce pain and inflammation in people with symptomatic apical periodontitis, a painful infection at the tooth root. Half of the 50 adult participants receive the standard paste, while the other half gets the silver-enhanced version. Researchers measure pain levels and inflammatory markers in the gum fluid before and after treatment, and check bone healing at 3 and 6 months.
