“…After applying the inclusion/exclusion criteria to the titles and abstracts of the selected comparative studies, 17 studies remained. Reading these study texts resulted in exclusion of 8 more studies because they were performed in less than 10 patients [22], had an unclear description of/ or unappropriate randomization [39,40,5,7], had subjective criteria for evaluating results [13], maxillary expansion with follow-up less than 30 days [10] and was a prospective study [41]. A manual search for articles identified six more studies.…”

“…In Medicine, this and other therapies have been applied for surgical scars [2,3], and for wrist and hand fractures [4]. In Dentistry, laser therapy has been clinically used and evaluated for post-surgical tooth extraction [5][6][7][8], after rapid maxillary expansion [1,9,10], after connective tissue graft harvesting in the mucosal palate [11], for treatment of jaw osteonecrosis [12,13], and for periodontal defects [14,15].…”

Within the limitation of this review, a possible improvement in bone density can be found when LLLT is applied postoperatively in maxillofacial bony defects. LLLT also seems to promote anti-inflammatory and analgesic effects and accelerate healing, as well as enhance quality of life related to oral health. However, LLLT use protocols need to be standardized before more specific conclusions can be drawn about this subject.

“…Researches have observed that laser therapy associated to midpalatal suture expansion is effective for bone regeneration, accelerating mineral apposition velocity and producing a faster repair process in the area 1,9,[26][27] . Since we were unable to find any previous reports in the literature concerning the use of LED associated to expansion of the midpalatal suture, it makes our discussion of our results very difficult in this aspect.…”

A quick bone formation after maxillary expansion would reduce treatment timeand the biomodulating effects of LED light could contribute for it. The aim of this study was to analyze the effect of LED phototherapy on the acceleration of bone formation at the midpalatal suture after maxilla expansion. Thirty rats divided into 6 groups were used on the study at 2 time points -7 days: Control; Expansion; and Expansion + LED; and 14 days: Expansion; Expansion + LED in the first week; Expansion and LED in the first and second weeks. LED irradiation occurred at every 48 h during 2 weeks. Expansion was accomplished using a spatula and maintained with a triple helicoid of 0.020" stainless steel orthodontic wire. A LED light (λ850 ± 10nm, 150mW ± 10mW, spot of 0.5cm 2 , t=120 sec, SAEF of 18J/cm 2 ) was applied in one point in the midpalatal suture immediately behind the upper incisors. Near infrared Raman spectroscopic analysis of the suture region was carried and data submitted to statistical analyzes (p≤0.05). Raman spectrum analysis demonstrated that irradiation increased hydroxyapatite in the midpalatal suture after expansion. The results of this indicate that LED irradiation; have a positive biomodulation contributing to the acceleration of bone formation in the midpalatal suture after expansion procedure.

“…The light was typically applied to the tissue surface of the region of interest. The primary purpose of this research was to investigate whether the PBM can increase BMR activities 1,2,7,[18][19][20][21] and stimulate cell proliferation. 18,[22][23][24][25] Research on cell response to PBM demonstrates positive effects, supporting the conclusions of the animal studies that PBM can accelerate cell proliferation and increase BMR.…”

The objective of this study was to evaluate the effects of varying light doses on the viability and cellular activity of osteoblasts, osteocytes, and osteoclasts. A light application device was developed to apply 940-nm wavelength light from light-emitting diodes on three cultured cells, MC3T3-E1, MLO-A5, and RANKL-treated RAW264.7 cells. The doses (energy density) on cells were 0, 1, 5, and 7.5 J / cm2. The corresponding light power densities at the cell site were 0, 1.67, 8.33, and 12.5 mW / cm2, respectively, and the duration was 10 min. The results showed that the three cell types respond differently to light and their responses were dose dependent. Low-dose treatment (1 J / cm2) enhanced osteoblast proliferation, osteoclast differentiation, and osteoclastic bone resorption activity. Osteocyte proliferation was not affected by both low- and high-dose (5 J / cm2) treatments. While 1 J / cm2 did not affect viability of all three cell types, 5 J / cm2 significantly decreased viability of osteocytes and osteoclasts. Osteoblast viability was negatively impacted by the higher dose (7.5 J / cm2). The findings suggest that optimal doses exist for osteoblast and osteoclast, which can stimulate cell activities, and there is a safe dose range for each type of cell tested.
