Low Intensity Laser Versus Synthetic Bone Graft To Increase Bone Density After Enucleation Of Large Cystic Lesions Of Jaws

Material and Methods: This study included 27 patients of both sex (17 males & 10 females) aged 20 48 years. They were divided into 3 groups, each group contained 9 Patients. All patients in all groups were selected to have large cystic cavities in their dental arches of different etiological factors, ranged in diameter 1.5 – 3.5 cm, and not approaching any vital structures. They underwent surgical enucleation of these cystic lesions. Patients of group (I) have received bone substitute in form of Algipore granules that were packed inside the bony cavities of enucleated cysts till complete filling. While Patients in group (II) have not received any grafting materials after cysts enucleation, but low intensity diode laser was applied to all of them in six sessions for each patient. Patients in group (III), control group, have not received any grafting materials after cysts enucleation. Radiographic evaluation of all patients was performed using digital radiography system (Digora). Radiographs were taken preoperatively and at intervals of 1 day, 6 weeks, 3 months and 6 months post surgically. The mean bone density at the same region of opposite side was also measured for comparison. Results: It was found that there was a significant higher bone density in Algipore group than other two groups at 1 day and 6 weeks time intervals, while there was no significant difference between Algipore and Laser groups at 3 months and 6 months post surgically. But both groups showed significantly higher bone density than control group at these 3 & 6 months time intervals. Furthermore, the bone density was significantly higher in Laser group than control group at 6 weeks time interval. In control group, there was no significant difference in bone density between all time intervals. In group I & II, there were significant increase in bone density in all time intervals compared with preoperative density, but, there were no significant difference in bone density between different time intervals in control group. Conclusion: Algipore (CORALS) can be a dependable bone substitute material for grafting bony defects in both jaws, Low intensity laser has also the ability to significantly increase bone density of empty cavities of jaws after enucleation of large cysts, so, it is preferred than Algipore specially with cases having infected lesions .
