“…Na cicatrização de feridas, a proliferação celular começa caracteristicamente das margens da ferida e se estende ao seu centro, principalmente por causa da baixa disponibilidade de nutrientes e oxigênio neste site (Ribeiro, et al, 2015). Portanto, o tamanho e a profundidade da ferida é um fator importante a se considerar na análise do reparo e na comparação entre estudos.…”

A cicatrização de feridas é um processo complexo, composto por vários estágios interdependentes e simultâneos com o objetivo de reparar o tecido e, dentre os métodos que utilizados, a laserterapia apresenta efeitos estimuladores biológicos e regenerativos. O objetivo dessa revisão é compreender o mecanismo de ação da laserterapia na reparação tecidual e, mais especificamente, na angiogênese. Foi realizada uma pesquisa bibliográfica nas bases de dados PUBMED, LILACS e SCIELO sobre o assunto, utilizando as seguintes palavras-chave: "fototerapia e angiogênese" e "fototerapia e cicatrização de feridas". Nessa busca, foram totalizados 3634 artigos que após análise dos critérios, foram excluídos 3624, restando 10 trabalhos. Diante do exposto, pode-se concluir que a laserterapia tem se apresentado como uma alternativa terapêutica na reparação tecidual, atuando como fotobiomodulador, com efeitos analgésicos, anti-inflamatórios, anti-edema e antimicrobianos, oferecendo melhorias no mecanismo de resposta celular e apresentando vantagens nas três etapas do processo de cicatrização.

“…13,23 Several studies have reported the utilization of aPDT for inhibition and microbial control in treatment and decontamination in different surfaces such as the oral cavity. [24][25][26][27][28][29] Considering the few numbers of studies on the efficacy of aPDT in comparison with different mouthwashes for the disinfection of orthodontic appliances, this study evaluated the efficacy of aPDT, chlorhexidine (CHX), sodium fluoride (NaF), and hydrogen peroxide (H 2 O 2 ) for the disinfection of acrylic resin.…”

Introduction: Plaque accumulation on the surface of removable orthodontic appliances could lead to dental caries, periodontitis, and fungal infections. This study evaluated the effectiveness of antimicrobial photodynamic therapy (aPDT), chlorhexidine (CHX), sodium fluoride (NaF), and hydrogen peroxide (H2 O2 ) for the disinfection of acrylic resin. Methods: In this in vitro experimental study, 100 acrylic resin specimens were randomly divided into five groups (n=20 each): Enterococcus faecalis, Streptococcus mutans, Streptococcus salivarius, Streptococcus sanguinis, and Lactobacillus acidophilus. Each group was immersed separately in 5 mL of microbial suspension. They were then incubated until biofilm formation on their surface. Of each microorganism, one biofilm sample in phosphate-buffered saline was considered as negative control, and other biofilm samples (n=80) were subjected to aPDT with curcumin, 0.12% CHX (positive control), 1% H2 O2 , and 0.2% NaF. Finally, the number of colonies was counted. Data were analyzed by the Kruskal-Wallis and Mann-Whitney tests, two-way ANOVA, and Bonferroni adjustment at a significance level of 0.05. Results: The interaction effect of the treatment modality and type of microorganism was significant on the microbial count (effect size: 0.91, P<0.05). Maximum bacterial proliferation was noted in the following combinations: NaF/E. faecalis, H2 O2 /E. faecalis, and H2 O2 /S. salivarius. Microorganisms had no or insignificant growth and proliferation in the aPDT and CHX groups. Conclusion: The results supported the optimal antimicrobial efficacy of PDT which was comparable to that of CHX. aPDT showed superior antimicrobial efficacy to NaF and H2 O2 for the disinfection of acrylic resin.

“…The results showed that the LED-irradiaton was able to accelerate the wound healing process. In addition, a statistically significant microbial reduction was obtained with photodynamic inactivation compared to chemical decontamination [76]. Other types of model of study have been tested, such as the adult human skin wound healing organ culture (WHOC) treated with PDT.…”

Skin is the largest human organ and displays multiple functions involving structure and protection against external agents that may affect the body. Solar radiation accelerates the normal aging process and may even cause great damage leading to many different cutaneous diseases and skin cancer. Moreover, a wound in the skin may be an open channel for the access of pathogens usually exposing blood vessels for infections and causing serious complications. For many reasons, regulatory skin processes are of great deal in different approaches: basic antiaging, wound healing, and skin cancer. In a good way, photoprocesses with specific wavelength at low energy levels associated with photoactive compounds are known to cause the opposite effect, promoting the healing of cutaneous diseases and leading to well-defined outcomes in rejuvenation and antiaging. This chapter will discuss the most relevant topics in photo skin regeneration using low energy levels associated with photodynamic therapy (PDT), which emerged as a combination to potentialize molecules with the already known effects of PDT and low level laser therapy (LLLT) in the treatment of skin pathologies, known as a photobiomodulation process.
