“…These effects can be achieved using wavelengths between 600 and 1000 nm. In this sense, clinical and experimental studies with partial and total thickness burns have used photobiomodulation with LLLT with a wavelength of 660 nm 21 , ratifying choice of this parameter also in our study ( 5 , 19 , 22 , 23 ) .…”

Objective: to evaluate the effect of photobiomodulation with low-level 660 nm laser alone or associated with Human Amniotic Membrane in the repair of partial-thickness burns in rats. Method: an experimental study conducted with 48 male Wistar rats, randomized into four groups: Control, Human Amniotic Membrane, Low-Level Laser Therapy, and Low-Level Laser Therapy associated with Human Amniotic Membrane. The histopathological characteristics of the skin samples were analyzed 7 and 14 days after the burn. The data obtained were submitted to the Kolmogorov-Smirnov and Mann-Whitney tests. Results: the histological analysis of the burn injuries showed a decrease in inflammation (p<0.0001) and an increase in proliferation of fibroblasts (p<0.0001) mainly at 7 days in all treatments related to the control group. At 14 days, the greater effectiveness in accelerating the healing process was significant (p<0.0001) in the Low-Level Laser Therapy group associated with the Human Amniotic Membrane. Conclusion: the association of photobiomodulation therapies with the Human Amniotic Membrane allowed verifying a reduction in the healing process time of the experimental lesions, stimulating its proposal as a treatment protocol in partial-thickness burns.

Resumo Objetivo: avaliar o efeito da fotobiomodulação com laser de baixa intensidade 660 nm isoladamente ou associada à membrana amniótica humana no reparo de queimaduras de espessura parcial em ratos. Método: estudo experimental com 48 ratos Wistar machos, randomizados em quatro grupos: Controle, Membrana Amniótica Humana, Terapia a Laser de Baixa Intensidade e Terapia a Laser de Baixa Intensidade associado à Membrana Amniótica Humana. As características histopatológicas das amostras de pele foram analisadas aos 7 e 14 dias após a queimadura. Os dados obtidos foram submetidos aos testes de Kolmogorov-Smirnov e Mann Whitney. Resultados: a análise histológica das lesões por queimadura mostrou a diminuição da inflamação (p <0,0001) e aumento da proliferação de fibroblastos (p <0,0001), principalmente nos 7 dias em todos os tratamentos relacionados ao grupo controle. Aos 14 dias, a maior efetividade na aceleração do processo cicatricial foi significativa (p<0,0001) no grupo Terapia a Laser de Baixa Intensidade associado à Membrana Amniótica Humana. Conclusão: a associação das terapias de fotobiomodulação à membrana amniótica humana permitiu comprovar redução no tempo do processo cicatricial das lesões experimentais, estimulando sua proposição como protocolo de tratamento em queimaduras de espessura parcial.

“…The synergistic power of biostimulation has been approved in many applications as it reduced post endodontic surgical pain and favored the bone density (9) , enhanced osteointegration around immediate implant placement compared to ozone therapy (10) and enhanced wound healing (11) . In regenerative endodontics, is worth to be mentioned that the effect of biostimulation was highlighted where large periapical lesion was associated with necrotic immature incisor responded to the disinfection and biostimulation protocol by 980 nm diode laser irradiation with accelerated healing rate (12) .…”

Purpose: This study was carried out to evaluate the effect of biostimulation on the regenerative response of immature teeth with necrotic pulp and apical periodontitis in dogs. Materials and Methods: Seventy-two root canals were employed in the present study as follows: Sixty root canals for experimental groups and twelve as positive and negative controls. After the induction of pulp necrosis and apical periodontitis, roots were divided into two groups, group I: Regenerative Endodontic Therapy (RET) with subsequent biostimulation (seven sessions at 808 nm diode laser at output power of 300 mW for 90 seconds) and group II: RET without biostimulation. The groups were followed up for 1, 2 and 3 months (subgroups A, B&C). The maturation of the roots was assessed both radiographically and histologically. All data were statistically analyzed.Results: the application of biostimulation in group I demonstrated marked increase in root length, thickness and decrease in apical diameter compared to group II however, it was statistically significant only in subgroup C (12.43% versus 7.66%, 33.09% versus 17.81% and 38.12% versus 23.35 % at third month) respectively (p<0.05). Furthermore, it showed histologically the highest score of vital tissue infiltration and least inflammatory scores which was statistically significant. Conclusion: Biostimulation enhanced the response of immature teeth with necrotic pulp and apical periodontitis to regenerative endodontic therapy improving root maturation.
