The Usage of Low Level Laser Therapy Bio Stimulation and Bone Grafting in Accelerating the Healing of chronic intra-Osseous Defects: Vivo Study

The application of LLLT has become popular in the promotion of wound healing and reduction of pain following nonsurgical and surgical procedures. The aim of this article was to evaluate the efficiency of an SBX putty nano-bone graft with and without applying LLLT in accelerating the bone formation of the intra-bony defects through apical curettage without apicoectomy. In this study a total of 30 upper anterior maxillary teeth with periapical lesions. Patients were divided into two equal groups: Group I: apical curettage without apicoectomy and applying SBX putty nano-bone graft inside the intra-bony defects (n=15). Group II: apical curettage without apicoectomy, applying SBX putty nano-bone graft inside the intra-bony defects and then treating the defect with LLLT (n=15). CBCT was taken to determine the approximate size of periapical radiolucencies, All patients were followed up using CBCT for 1 year for evaluation of the size of the radiolucent area and bone density. Results showed that the differences in bone density measured on the panoramic as well as the cross-sectional views at all time intervals were non-significant (p<0.05) Conclusion: The Use of both SBX nano-bone graft and LLLT is considered an optimum choice for accelerating the healing of intra-bony defects.
