Intrabony defect regeneration is achieved by various regenerative techniques one of which is Low Level Laser Therapy (LLLT) biostimulation along with open flap debridement (OFD). Conversely, LLLT through its biostimulatory effects it promotes faster wound healing through fibroblast proliferation and release of various growth factors and improves vascularity. It also induces advanced new bone formation and matrix production from osteoblastic cells. Additionally, it causes less post–operative pain, hematoma and good patient compliance compared to conventional therapy.
