“…Nowadays, laser has become an indispensable tool in the dental office [1][2][3]. It is used as a treatment device that has replaced surgical instruments such as the scalpel; it improves the patient's postoperative comfort by minimizing pain and swelling [4]. Depending on the type, the laser may be used in the area of soft and hard tissues.…”

Purpose: to assess the effect of photobiomodulation (PBM) on human gingival fibroblast proliferation. Methods: The study was conducted using the primary cell cultures of human fibroblasts collected from systemically healthy donors. Three different laser types, Nd:YAG (1064 nm), infrared diode laser (980 nm), and prototype led laser emitting 405, 450, and 635 nm were used to irradiate the fibroblasts. Due to the patented structure of that laser, it was possible to irradiate fibroblasts with a beam combining two or three wavelengths. The energy density was 3 J/cm2, 25 J/cm2, 64 J/cm2. The viability and proliferation of cells were determined using the (Thiazolyl Blue Tetrazolium Blue) (MTT) test conducted 24, 48, and 72 h after laser irradiation. Results: The highest percentage of mitochondrial activity (MA = 122.1%) was observed in the group irradiated with the 635 nm laser, with an energy density of 64 J/cm2 after 48 h. The lowest percentage of MA (94.0%) was observed in the group simultaneously irradiated with three wavelengths (405 + 450 + 635 nm). The use of the 405 nm laser at 25 J/cm2 gave similar results to the 635 nm laser. Conclusions: The application of the 635 nm and 405 nm irradiation caused a statistically significant increase in the proliferation of gingival fibroblasts.

“…It was also evident that most of the studies (14/17), independent of the fields considered (conventional, aPDT or PBMT), evaluated the effect of laser use in pain management as a major concern in the delivery of endodontic therapy. However, as a result of the subjective nature of pain perception, studies evaluating pain intensity were found to be highly heterogenous [ 19 ]. Consequently, in two of the studies [ 31 , 40 ], in addition to the visual analog scale (VAS)-pain evaluation, a quantification of calcitonin gene-related peptide (CRGP) in gingival crevicular fluid (GCF) and its correlation with pain, was assessed.…”

“…Specifically, apical extrusion of tooth debris or irrigants, intra-canal dressings and micro-organisms might occur, resulting in inflammation and pain [ 17 ]. This irritation contributes to nociceptor activation and local inflammation, leading to a release of prostaglandins, bradykinin, leukotrienes, serotonin and cytokines from the injured tissues, which therefore potentiates peripheral sensitization [ 18 , 19 ].…”

(1) Background: Adjunctive instruments, such as lasers have been investigated to address the risk of failure of endodontic therapy due to the complexity of the root canal system. Lasers have been used therapeutically, in direct irradiation of the root canals or adjunct to irrigants placed into the canals, in combination with a photosensitizer (antimicrobial photodynamic therapy) and in pain management (photobiomodulation). The purpose of this systematic review was to evaluate the evidence in clinical use within these three areas of therapy. (2) Methods: PubMed, Cochrane and Scopus search engines were used to identify human clinical trials regarding the use of lasers in endodontic therapy. (3) Results: After applying the keywords and additional filters, inclusion and exclusion criteria, the initial number of 1486 articles was reduced to 17. It was revealed that almost all studies (14/17) presented a statistically significant improved outcome in laser-assisted endodontic therapy, with the remaining three not showing any adverse effects. (4) Conclusions: The use of laser photonic energy of appropriate delivered parameters can be proposed as useful adjunctive when considering optimal treatment modalities in orthograde endodontics. Additionally, a tendency of research towards pain modulation in this field is developing.

“…Nesse contexto, a terapia fotodinâmica desponta como uma nova terapia, coadjuvante ao tratamento endodôntico convencional, na tentativa de eliminar microrganismos persistentes ao preparo químico-mecânico. Sendo uma técnica de fácil e rápida aplicação clínica e indolor, não desenvolve resistência microbiana, podendo ser indicada em tratamentos endodônticos em sessão única ou em múltiplas sessões 6,7 . Diante do exposto, o presente estudo tem como objetivo geral apresentar aos cirurgiõesdentistas e a sociedade a nova face da Odontologia voltada à utilização da terapia fotodinâmica associada a laser na prática endodôntica.…”

Introdução: A terapia fotodinâmica associada a laser tem sido estudada e aplicada em diversas especialidades da Odontologia objetivando o uso de técnicas menos invasivas. Objetivo: Este estudo tem como objetivo apresentar aos cirurgiões-dentistas e à sociedade a nova face da Odontologia voltada à utilização da terapia fotodinâmica associada a laser na prática endodôntica, bem como, apresentar os aspectos gerais da laserterapia. Material e Metódos: Trata-se de uma revisão de literatura, caracterizada como descritiva e exploratória. Foram realizadas buscas em livros, artigos científicos, monografias, dissertações e teses, no período de agosto de 2018 a maio de 2019. Esses dados foram obtidos por meio de bases de dados MedLine, PubMed, Scielo, LILACS e BBO. Resultados: Os resultados mostraram que a terapia fotodinâmica associada a laser é efetiva como coadjuvante ao tratamento endodôntico convencional, sendo uma das principais utilizações auxiliar na desinfecção dos canais radiculares, que consiste em utilizar uma fonte de luz com comprimento de onda específico capaz de estimular um agente fotossensível , que resulta em danos oxidativos, causando a morte celular. São observados também estudos do seu desempenho no preparo cavitário, controle da vitalidade pulpar, capeamento pulpar e pulpotomia, limpeza dos condutos radiculares, obturação e adesão dos cimentos endodônticos, retratamento, cirurgias periapicais, redução da dor e reparação pós-operatória. Conclusão: Concluiu-se que a terapia fotodinâmica utilizada como coadjuvante à terapia endodôntica convencional aumenta a previsibilidade de sucesso do tratamento, desde que, o conhecimento sobre os fundamentos e interações com os tecidos biológicos sejam esclarecidos e dominados pelo profissional.
