“…17,18 We also found a statistically significant increase in collagen fiber deposition in group E-20, compared with all other groups, which can be attributed to increased fibroblast activity and proliferation induced by the biomodulatory effects of laser therapy. 10,13,23,24 Laser irradiation has been shown to have a positive effect on the early stages of osseointegration. 8,15,18,23,25,26 Therefore, in this study, rabbits were exposed to a 13 day LLLT protocol, which corresponds to the initial bone healing period after implantation.…”

However, the multiplicity of models used for this purpose and lack of consensus on dosing protocols prevent adequate comparison among studies.…”

“…This effect may be combined with a bone regeneration delay in the presence of biomaterials, as already documented in previous studies. Thus, in support of this hypothesis, several authors suggested the same conclusions [33,70], finding that the positive effects of photobiomodulation on bone healing are more obvious when applied intraoperatively, directly to the bone defect, prior to the grafting procedure [33].…”

“…The same aspects have been investigated throughout many in vivo studies, using different animal models, wavelengths, and irradiation protocols. Most of these studies presented improvements during the early stages of the healing period [32], with significant differences in the calcium hydroxyapatite concentration, as well as in the quantity of newly formed bone and of collagen fibers [33]. Other studies [34] observed increased mineralization in the laser-treated groups and increased levels of calcium, phosphorus, and proteins in comparison to the untreated groups [30].…”

“…In contrast, several lines of studies reported that the combination of LILT with growth factors or biomaterials accelerates osteoblast differentiation and bone regeneration. It has been indicated that the combination of LILT with graft of autologous bone or inorganic bovine bone [71][72][73][74], enamel matrix derivative [75], and BMPs [76][77][78] accelerated bone regeneration, compared with LILT alone or biomaterials alone. Recently, we examined effects of LILT by Ga-Al-As laser on BMP2 induced osteoblastogenesis [79], and found that low intensity laser irradiation accelerated BMP2-induced transcription factors such as Id1, Osterix, and Runx2, expressions of type I collagen, osteonectin, and osteocalcin mRNA, markers of osteoblasts, and activation of Smad1/5/8 as well as alkaline phosphatase, in C2C12 myoblast cells that differentiate into osteoblasts by exposure to BMP2.…”
