Photographic images and illustrations of the RP-14 device (a) used in the present clinical trial for periodontal treatment (b). The RP-14 is equipped with an ultrasonic scaler and a laser unit that emits light at a wavelength of 405 nm. The hollow-type, steel scaler tip and disposable plastic optical guide were used for treatment in Group 1 (root debridement + H2O2 photolysis treatment). Laser light at 50 mW and 3% H2O2 are released from the end of the scaler tip. As a result, hydroxyl radicals are generated in the periodontal pocket during root debridement.
