Ultrasonic debridement
All periodontal pockets received ultrasonic debridement (Cavitron, Dentsply) with specific inserts (UI25KSF10S, Hu-Friedy). All diseased sites were instrumented in one session by an experienced periodontist.
Antimicrobial photodynamic therapy
After ultrasonic debridement, one randomly selected periodontal pocket received an additional aPDT performed by a trained operator (NMRBA). One pocket with probing depth ≥ 5mm in each patient was randomly selected to aPDT. After washing the pocket with saline solution, the photosensitizer (methylene blue 10mg/ml) was applied to the bottom of the pocket in a coronal direction. Following this, the pocket was exposed to a diode laser light with a fibre optic application for 1 min (Thera Lase DMC - Brazil), with wavelength of 660nm, power of 60mW and fluency of 129J/cm2.
