In this study, we meticulously evaluated and compared seven different irrigation solutions using a human ex vivo organ culture methodology to closely replicate surgical conditions. By analyzing a range of options, including PHMB (polyhexamethylene biguanide), PVP-I (povidone-iodine), CHG (chlorhexidine gluconate), BZK (benzalkonium chloride), and acids we aimed to pinpoint the most effective solutions that provide robust antibacterial activity while ensuring tissue safety.
