Low-level laser efficiency in reparation of bone defects

Introduction/Objective. Bone resorption is a common problem in dentistry, and bone reparation cannot be easily achieved. Several techniques of grafting the use low-level laser treatment (LLLT) as new therapeutic optional recommended for improving repair were applied. The aim study was to investigate influence LLLT artificially made defects rat mandible using histomorphometry. Methods. research carried out on 60 female rats. mandible, animals divided into two groups, each containing 30 animals. In group, implantation site submitted GaAlAs irradiation 670 nm, 5 mW, 4 minutes per day days. control group had no postoperative treatment. sacrificed after two, six, eight weeks post LLLT, preparations analysed by histomorphometry, determining area fraction, area, integral density, mean density variation. Results. Histomorphometric analysis revealed statistically higher values six weeks. However, beneficial effect noticed Conclusion. Low-level lasers have stimulating reparatory mechanisms early regeneration stage can used useful helping method
