Adjunctive Laser for Periodontal Intrabony Defects

Effects of Adjunctive Er, Cr :YSGG Laser Treatment to Nonsurgical Periodontal Treatment on Healing of Intrabony Periodontal Defects: a Randomised Controlled Trial

Participants with periodontitis and presence of bilateral intrabony defect will be randomised to have one side of the mouth undergo root surface debridement using hand instruments and ultrasonic scaler alone, while the contralateral side will receive the same treatment, with the addition of the Er:YAG laser. Outcomes studies will be periodontal clinical parameters at 3 months, 6 months, 9 months and 12 months after treatment, radiographic parameters at 12 months, patient-reported parameters and laboratory analyses.

The study is a Double-masked randomised controlled trial with split-mouth design.
