text: Yo, check it out, this study aimed to see
  How peracetic acid (PAA) affects the scene
  On the smear layer, dentin bond strength too
  And the penetrability of epoxy resin sealer, true
  
  They took 120 roots, divided 'em four ways
  Different irrigants for those root canals they raise
  One was 1% PAA, that's the PAA group
  NaOCl-EDTA-NaOCl, NaOCl, and SS, the rest of the troops
  
  They used scanning electron microscopy
  To evaluate the smear layer, you see
  Push-out test for the epoxy resin sealer's bond strength
  Confocal laser microscopy to see the sealer's length
  
  Kruskal-Wallis and Dunn post-test brought the stats
  With α = 0.05, no room for chit-chat
  1% PAA showed smear layer removal, no joke
  Penetrability and bond strength like NaOCl-EDTA-NaOCl, just spoke
  
  NaOCl and SS groups had higher smear layer scores
  Lower sealer penetrability and bond strength, that's for sure
  PAA and NaOCl-EDTA-NaOCl groups came out on top
  P < 0.05, they made the other groups drop
  
  So 1% PAA got the potential, no doubt
  To be a single irrigant in root canals, shout it out!
