ABSTRACT
Aim Of The Study: Evaluated The Efficacy Of A New Material With And Without Low Intensity Laser Treatment In Accelerating Bone Formation Of An Apical Radiolucency Through A Surgical Procedure.

Materials and Methods: 20 Upper Anterior Maxillary Teeth., With Periapical Lesions Ranging From 5-8mm In Diameter. Patients Were Divided Randomly Into Two 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). Cone Beam Was Taken To Determine The Presence Of Periapical Radiolucency And Its Approximate Size, 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), While 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 A (NBG) Had Shown The Highest Grey Scale Value Regarding The Other Group (LG). Conclusion: The Use Of Low Intensity Laser Decrease The Post-operative Pain And Symptoms, The Use Of CBCT Is Considered The Only Effective Method For Measuring The Bone Density Or The Grey Value.
