Management of perio-endo interface complex case with NaOCl photoactivated with 980 nm to optimize root canal system decontamination with 12-month follow-up

Root canal system decontamination is recognized as one of the main pillars of successful endodontic treatment, although variations in the efficacy of current disinfection methods have been reported. In light of this, the present study investigated the activation of 5.25% sodium hypochlorite (NaOCl) using a 980 nm diode laser (laser-activated irrigation) as an adjunct to conventional decontamination, with the addition of photobiomodulation therapy. The objectives were to achieve optimal clinical outcomes over long-term follow-up, to alleviate post-endodontic pain, and to propose effective decontamination treatment protocols.
