title: Patients' perceptions of antimicrobial photodynamic therapy in the management of chronic periodontitis.
abstract: The aim of this study is to evaluate patients' perception of antimicrobial photodynamic therapy (aPDT) in the management of chronic periodontitis. 90 patients (51 females and 39 males) with untreated localized chronic periodontitis were randomly assigned to receive SRP with aPDT (test group) or SRP alone (control group) in a single-centered double-blinded randomized and controlled clinical trial. Patients' perception in terms of changes in bleeding gums, pain in gums while chewing, bad breath and sensitive gums along with pain during the procedure and patient acceptance were recorded for 6 months after treatment by a periodontist who was blinded to the procedure. Inter-group and intra-group statistical analyses were performed. Significant difference between the frequencies of two groups with respect to each variable was assessed using non-parametric test. Patients' report of bleeding gums and pain in the gums while chewing showed statistically significant reduction in the test group at 2 weeks and 1 month (p<0.05). Also, a significant difference was detected at 1 month between SRP and SRP+aPDT in terms of halitosis (p<0.05). No statistically significant change was observed between two groups in terms of sensitive gums, pain during procedure and patient acceptance. Patients perceived short-term benefits of single session of aPDT therapy due to the reduction in bleeding gums, halitosis and pain while chewing following treatment. Further studies are required to assess the effectiveness of aPDT for a longer-term and following multiple sessions.
