The purpose of this study was to evaluate the efficacy of a new material with or without Low intensity laser treatment in accelerating bone formation of an apical radiolucency through a surgical procedure. In this study a total of 30 upper anterior maxillary teeth with periapical lesions ranging from 5-8mm in diameter. Patients were divided randomly into three groups: Group A: Curettage and Filling osseous defect with Nanobone graft only (n=10).Group B: Curettage and treating the Osseous defect with Laser only (n=10).Group C: Curettage and Filling Osseous defect with Nanobone graft and treating the defect with Low intenisty laser (n=10). Cone beam was taken to determine the presence of periapical radiolucency and its approximate sizes, all patients were followed up using CBCT at 3, 6 and 12 months interval for evaluation of the bone density and size of the radiolucent area. Results: The results of our present study in case of panoramic view (CBCT), it was found that group A (NBG) and C(L+NBG) showed increase in the grey scale value(bone density), while the third group B(LG) had shown lowest grey scale value, on the other hand, in case of cross-section view (CBCT), it was found that group C(L+NBG) had shown the highest grey scale value regarding the other two groups (NBG, LG). Conclusion: The use of Nano-bone graft and Low intensity laser technique in endodontic surgery is considered an optimum choice, as they both accelerate bone and tissue healing, the use of Low intensity laser decrease the postoperative pain and symptoms, the use of CBCT is considered the only effective method for measuring the bone density or the grey value.
