Low level laser has been documented in literature to promote wound healing by reducing postoperative inflammation, oedema and reduces pain. This case report demonstrates the safe and positive outcome of LLLT in conjunction with demineralised bone matrix of bovine origin in the surgical treatment of a periodontal infrabony defect. After surgical defect debridement, low level semiconductor diode laser (GaAlAr) was delivered for 5 minutes to the inner margins of flap in contact mode and the defect was irradiated with LLLT in a non-contact mode for 10 minutes. Demineralised bone matrix graft was used as a bone grafting material. Repeat irradiation was done for the next 5 days on the outer buccal and lingual flap surfaces. A CAL gain of 4 mm and 37% bone fill was noted radiographically at end of 12 months. LLLT can be used as an adjunct to periodontal regeneration.
