Giannelli M, et al. - The authors conducted a trial for the purpose of determining the efficacy and safety of a photoablative-photodynamic diode laser therapy, including antiseptic light-emitting diode (LED) irradiation in adjunct to scaling and root planning (iPAPD+SRP) vs sham-treatment+SRP for the treatment of diffuse severe periodontitis. Additionally, they investigated the patient-reported outcomes. As per the results, the patients’ perceived pain/discomfort and overall liking were in favor of the iPAPD+SRP treatment. Hence, the efficacy of combined phototherapy in adjunct to SRP was affirmed, which in turn, extended its field of application to severe periodontitis.
