ABSTRACT

Abstract 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.

ABSTRACT

Introducción: El dolor es el síntoma más común luego de la primera activación de la aparatología ortodóncica. El tratamiento analgésico más utilizado es el paracetamol; sin embargo, su uso inhibe la actividad de la ciclooxigenasa y la síntesis de prostaglandinas, lo que puede afectar el mecanismo del movimiento dental y el remodelado óseo. Objetivo: Evaluar la efectividad del láser de baja potencia para el alivio del dolor en pacientes con tratamiento ortodóntico. Métodos: Se realizó un estudio cuasiexperimental de intervención terapéutica, desde enero hasta diciembre de 2020, en 40 pacientes atendidos en la consulta de ortodoncia del Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba, en quienes se aplicaría fuerza ortodóncica por primera vez. Estos fueron distribuidos de forma aleatoria en 2 grupos de 20 integrantes cada uno: el de estudio, tratado con láser de baja potencia, y el de control, que recibió medicación convencional (paracetamol). Para la validación estadística de la información se emplearon el porcentaje y la prueba de la t de Student para muestras independientes, con 95 % de confiabilidad. Resultados: Luego de tres sesiones terapéuticas, 90,0 % del grupo de estudio refirió no presentar dolor o sentirlo de forma leve, mientras que del grupo de control solo 10,0 % de los pacientes fue ubicado en cualquiera de las dos categorías anteriores. Existió diferencia significativa entre ambos grupos (p=0,00). Conclusiones: Se demostró que el láser, como terapia alternativa, fue más efectivo que el paracetamol.


Introduction: Pain is the most common symptom after the first activation of orthodontic appliance. The most widely used analgesic treatment is paracetamol; however, its use inhibits cyclooxygenase activity and prostaglandin synthesis, which can affect the mechanism of tooth movement and bone remodeling. Objective: To evaluate the effectiveness of low power laser for pain relief in patients with orthodontic treatment. Methods: A quasi-experimental study of therapeutic intervention was carried out, from January to December 2020, in 40 patients treated at the orthodontic clinic of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba, in whom orthodontic force was applied for the first time. These were randomly distributed into 2 groups of 20 members each: the study group, treated with low-power laser, and the control group, that received conventional medication (paracetamol). For statistical validation of data, the percentage and the Student's t test for independent samples were used, with 95 % confidence interval. Results: After three therapeutic sessions, 90.0% of the study group reported not presenting pain or feeling it slightly, while only 10.0% of patients in control group were put in any of the two previous categories. There was a significant difference between both groups (p=0.00). Conclusions: Laser, as an alternative therapy, was shown to be more effective than paracetamol.

ABSTRACT

Objetivo: Analisar a eficácia do laser de baixa potência, modalidade local e sistêmico, para cicatrização e redução da dor ocasionadas por lesões mamilares. Métodos: Ensaio clínico, randomizado e controlado realizado com 54 lactantes atendidas em um Banco de Leite Humano, de dezembro de 2017 a junho de 2018. As lactantes, que somaram um total 101 lesões, receberam orientações referentes ao manejo clínico das mamas e foram alocadas em: Grupo Controle (GC), Grupo Laser Local (GLL), que receberam laser diretamente no mamilo lesionado e Grupo Irradiation Laser Intravascular of Blood (GILIB), que receberam a laserterapia sistêmica. Os dados foram analisados no SPSS para avaliação da homogeneidade dos grupos (Kruskal-Wallis) e regressão linear para identificação do efeito da intervenção no tamanho das lesões mamárias e intensidade da dor. Resultados: Os três grupos de análise se mostaram homogêneos antes do experimento (p=0,191). Após a intervenção, houve cicatrização das lesões nos três grupos, sendo significativamente maior no GLL e GILIB (p<0,050). Quanto à dor, houve redução em até 4.0 pontos no GLL e GILIB (p=0,002). Conclusão: A administração da laserterapia local e sistêmica foi mais eficaz para a cicatrização das lesões mamilares e redução da dor, quando comparadas ao grupo controle. (AU)


Objective: To analyze the effectiveness of the low-potency laser, local and systemic, for the healing and reduction of pain caused by nipple trauma. Methods: Clinical, randomized and controlled trial carried out with 54 lactating women assisted in a Human Milk Bank, from December 2017 to June 2018. The lactating women, which totaled 101 lesions, received guidance on the clinical management of their breasts and breasts designated in: Control Group (CG), Local Laser Group (GLL), which received laser directly on the injured nipple, and Intravascular Blood Laser Irradiation Group (GILIB), which received systemic laser therapy. Data were analyzed using the SPSS to assess the homogeneity of the groups (Kruskal-Wallis) and the linear regression to identify the effect of the intervention on the size of breast lesions and the intensity of pain. Results: The three analysis groups were homogeneous before the experiment (p=0.191). After the intervention, the healing of the lesions in the three groups was significantly higher in GLL and GILIB (p<0.050). As for the pain, there is a reduction of up to 4.0 points in GLL and GILIB (p=0.002). Conclusion: The administration of local and systemic laser therapy was more effective for the cure of nipple trauma and pain reduction, in comparison with the control group. (AU)

ABSTRACT

Search knowledge dentist front surgeon to low intensity laser through a questionnaire. They were selected randomly in the city of Juiz de Fora and region 91 Dental Surgeons of Minas Gerais. These employees were sent during the months from July to October 2013, a standard form printed with questions about laser education assessment of low intensity. Of the 91 participants, 42 (46.2%) were female and 49 (53.8%) were male. Fifty-seven (62.6%) had dental public institution of higher education; 32 (35.2%) attended a private institution and 2 (2.2%) did not report this data. Eighty-nine dentists reported the time of graduation, and this varied with a minimum of 1 year and a maximum of 38 years of training, the average being 11 years and this is the standard deviation of 10.7. The age of these professionals is on average thirty-five years, ranging from twenty-two years to sixty-five years of age and the standard deviation of this is 10.8. The distribution according to academic title was: 35 dentists (38.5%) had a degree in dentistry; 13 (14.3%) were specialists; 14 (15.4%) had master's and 4 (4.4%) doctorate. 25 (27.5%) did not report the academic title. The most relevant mentioned specialties were general practitioner, endodontics and implantology. We can conclude that the Juiz de Fora dentist - MG and region makes little use of laser therapy and this is mainly due to little knowledge acquired at the undergraduate and graduate education.

ABSTRACT

Introdução: A doença periodontal, de origem infecciosa, constitui diferentes quadros clínicos de caráter multifatorial e inflamatório. A fotobiomodulação é uma técnica não invasiva que tem demonstrado ser capaz de diminuir a inflamação e proporcionar alívio da dor. Estudos também demonstraram que a adoção da fotobiomodulação adjuvante à raspagem e alisamento radicular tem sido capaz de reduzir a carga bacteriana proveniente da periodontite crônica. Objetivos: Analisar os efeitos da fotobiomodulação como terapia adjuvante à raspagem e ao alisamento radicular no tratamento da periodontite crônica publicados nos últimos cinco anos. Métodos: Trata-se de uma revisão integrativa da literatura, realizada no período de setembro a novembro de 2021, mediante a utilização dos seguintes descritores: "Periodontitis", "Photobiomodulation" e "Therapy, selecionando artigos publicados em inglês durante o período entre 2016 a 2021. Resultados: Foram identificados 47 trabalhos. Destes, foram excluídos 39 estudos que se dispersaram do tema e 2 que se encontravam indisponíveis para o acesso, resultando em 6 artigos que foram consultados integralmente. Foi consenso entre os artigos consultados que a prática da fotobiomodulação tornou-se um potencial agente terapêutico no tratamento da periodontite crônica contribuindo para a redução da contagem de periodontopatógenos e que atua de maneira coadjuvante às raspagens radiculares. Conclusão: A fotobiomodulação mostrou-se uma ferramenta promissora na área odontológica. Entretanto, a grande variedade nos parâmetros de tratamentos e protocolos utilizados na fotobiomodulação impossibilita uma comparação e uma análise mais crítica e rigorosa dos resultados obtidos nos trabalhos analisados.


Introduction: Periodontal disease, which has an infectious origin, constitutes a multifactorial and inflammatory different clinical condition of multifactorial, inflammatory, and infectious origin. Photobiomodulation is a non-invasive technique that has been shown to decrease inflammation and provide pain relief. Studies also have shown that the choosing of photobiomodulation as adjuvant therapy to scaling and root planing has been able to reduce the bacterial load from chronic periodontitis. Objectives: To analyze the effects of photobiomodulation as an adjuvant therapy to scaling and root planing in the treatment of chronic periodontitis in the studies published in the last five years. Methods: This is an integrative literature review, carried out from September to November 2021, using the following descriptors: "Periodontitis", "Photobiomodulation" and "Therapy, from selected articles published in English during the period between 2016 to 2021. Results: From the research and selection of studies to compose this integrative literature review, 47 studies were initially identified based on the descriptors. From those, 39 papers that were outside from the topic and 2 papers that were unavailable for access were excluded from the present review. Then remained, 6 articles that were fully consulted. The practice of photobiomodulation has become a potential therapeutic agent in the treatment of chronic periodontitis reducing the count of periodontopathogens and as an adjunct therapy to root scaling. Conclusion: Photobiomodulation therapy has become a promising tool in the dental field, however, the great variety in the treatment parameters and protocols used for photobiomodulation makes impossible to compare and perform a more critical and rigorous analysis of the results collected in the present work.

ABSTRACT

Abstract Temporomandibular joint dysfunction syndrome (TMD), is a collective term characterized by symptoms involving chewing muscles, temporomandibular joint and orofacial structures. The efficacy of low intensity laser (LLLT) Gallium arsenide, in combination with a non-steroidal anti-inflammatory drug (NSAID) was evaluated. The main objective was to evaluate the maximum mouth opening without pain (ABM), arthralgia in the joint capsule through visual analog scale (VAS), laterality, protrusion, joint noises and count of tablets ingested per group. A controlled clinical trial (double-blind-randomized) was carried out in 30 subjects, who presented DTM of arthrogenic etiology; 5 applications of LLLT were made with wavelength of 810 nm, output optical power of 100-200 mw, emission PW=Pulsed (1-10,000Hz), dose of 10 jouls-cm², time of 1.44 minutes in mouth closed and with the mouth half open. One more follow-up appointment per month. There were two groups: experimental and control group, where different variables were analyzed (ABM, laterality, protrusion, VAS and sociodemographic). In the control group, a supposed LT application (not active) was made, for later comparison. Pain-free ABM was assessed in all appointments in addition to the other clinical parameters. Repeated measures analysis was performed with mixed models. Thirty patients were included of which 28 finished the treatment, two of them were lost during follow-up. The groups were similar in all their baseline variables. There were no statistically significant differences when applying the final multiple regression analysis, in the ABM, or in any other of the clinical parameters analyzed. LT was not effective in treating arthrogenic DTM.


Resumen El síndrome de disfunción de la articulación temporomandibular (DTM) es un término colectivo caracterizado por síntomas que involucran músculos de la masticación, articulación temporomandibular y estructuras orofaciales. Se evaluó la eficacia del láser de baja intensidad (LLLT) Arseniuro de galio, en combinación con un antiinflamatorio no esteroideo (AINE). El objetivo principal fue evaluar la apertura bucal máxima sin dolor (ABM), la artralgia en cápsula articular a través de escala visual análoga (EVA), lateralidades, protrusión, ruidos articulares y conteo de tabletas ingeridas por grupo. Se realizó un ensayo clínico controlado (doble ciego-aleatorizado) en 30 sujetos, que presentaban DTM de etiología artrogénica; se les realizaron 5 aplicaciones de LLLT con longitud de onda de 810 nm, potencia óptica de salida de 100-200 mw, emisión PW=Pulsed (1-10,000Hz), dosis de10 jouls-cm², tiempo de1.44 minutos a boca cerrada y con la boca semiabierta. Una cita más de seguimiento al mes. Se tuvieron dos grupos: experimental y grupo control, donde se analizaron diferentes variables (ABM, lateralidades, protrusión, EVA y sociodemográficas). En el grupo control se hizo una supuesta aplicación LT (no activo), para posterior comparación. En todas las citas se valoró la ABM sin dolor además de los otros parámetros clínicos. Se realizó análisis de medidas repetidas con modelos mixtos. Se incluyeron 30 pacientes de los cuales 28 finalizaron el tratamiento, dos de ellos se perdieron en el seguimiento. Los grupos fueron similares en todas sus variables basales. No hubo diferencias estadísticas significativas al aplicar los análisis de regresión múltiple finales, en la ABM, ni tampoco en ningún otro de los parámetros clínicos analizados. El LT no fue eficaz en el tratamiento de la DTM de origen artrogénico.

ABSTRACT

A lesão cervical não cariosa (LCNC) é uma doença caracterizada pela perda mineral do tecido dentário na região cervical. A sua progressão pode levar a hipersensibilidade dentinaria cervical (HDC). Apresenta etiologia multifatorial através de mecanismos de: fricção como a escovação (frequência, força, direção e creme dental abrasivo); tensão com sobrecarga oclusal (bruxismo e má-oclusão) e, principalmente, o mecanismo de corrosão através de doenças gástricas, transtornos alimentares e hábitos dietéticos (ingestão de ácido). Nos últimos anos é notório observamos a mudança de estilo de vida da população, e com isso um aumento da prevalência de HDC. É uma condição clínica comum caracterizada por uma dor aguda e transitória que surge devido a túbulos expostos em resposta a estímulos. Impacta negativamente a saúde bucal e a qualidade de vida dos pacientes. Para facilitar o entendimento, essa tese apresenta um compilado em três capítulos. Capitulo 1: O objetivo foi avaliar o pH de bebidas esportivas, energéticas, fitness/funcionais e suplementos, e a capacidade de neutralizar o ácido pela adição de saliva artificial, em um estudo experimental; capitulo 2: Avaliar o pH de bebidas, alimentos e medicamentos disponíveis no mercado brasileiro e a capacidade de neutralizar o ácido pela adição de saliva artificial; e capitulo 3: Através de um estudo clínico longitudinal randomizado, avaliar diferentes protocolos de tratamento da HDC com laser de baixa potência, agente dessensibilizante, e sua associação. Após as análises dos resultados ressalta-se que bebidas esportivas são comumente recomendadas por outros profissionais com o objetivo principal de atingir as metas de cada atleta, seja amador ou profissional. No entanto, como podem ter impacto na saúde bucal e um trabalho multidisciplinar é necessário, além de orientações para os pacientes esportivos. A maioria dos alimentos e bebidas consumidas por brasileiros são ácidas, e os resultados fornecem a dentistas e pacientes informações relevantes sobre as características do potencial corrosivo das bebidas comercialmente disponíveis no Brasil, sendo necessário orientações dietéticas específicas para prevenir ou minimizar o desgaste precoce dos dentes. E por último, encontrou-se que protocolo dessensibilizante de três sessões foi eficaz na redução da HDC após 3 meses, independentemente do mecanismo de dessensibilização utilizado.

Resultados: Después de la búsqueda de evidencias en la literatura, se elaboró un diagrama de flujo sobre los cuidados de enfermería realizados durante y después de la extravasación/infiltración. Además de las mediciones iniciales, se estandarizó el uso de hialuronidasa tópica y fotobiomodulación (1 a 3 julios, con una potencia de 100 milivatios). El área debe ser delimitada y, si es posible, fotografiada. Después de la validación del protocolo por un grupo de enfermeros especialistas y por la oficina de calidad, fue implantado en un Ambulatorio de Oncología de un Hospital Público del interior del Estado de São Paulo. Conclusión: aunque rara, la extravasación en el acceso central puede ocurrir y el equipo necesita un protocolo de atención para estandarizar la conducta y garantizar el éxito de la terapia.(AU)

ABSTRACT

INTRODUCTION: Rheumatoid arthritis (RA) is classified as an autoimmune, chronic disease affecting diarthrodial joints and periarticular structures. OBJECTIVE: To evaluate whether low-intensity laser treatment (LLLT) and/or exercise reduce the deleterious effects of tissue in a rheumatoid arthritis model. METHODS: 128 rats were divided into two inflammatory periods: acute (7 days) and chronic (28 days) and subdivided into control, injury and treatment. The protocol with Freund's Complete Adjuvant was used in two inoculations, one intradermal and one intraarticular in the tibiofemoral joint, the control animals received saline solution. For treatment, LLLT 660 nm, 5 J/cm² was used in the sensitized joint and climbing exercise in stairways with an overload of 100 grams. After the experimental period, the animals were euthanized and the joints were prepared for morphometric analysis of the total thickness, superficial, deep, and cellular density of the articular cartilage. Generalized Linear Models with Sidak post-test were chosen. RESULTS: The control group was found to be different from the lesion group with greater joint cartilage thickness, andthe animals treated with exercise alone increased the joint cartilage compared to thecontrol group. CONCLUSION: The animals treated with laser association and exercise showed improvement in the morphometric aspects of the articular cartilage.

ABSTRACT

INTRODUCTION: About 10 million people have low back pain (LBP) disability in Brazil. Several therapies are used to treat this condition, such as kinesiotherapy, manual therapy (MT), and photobiomodulation (PBM). Although the use of these methods in LBP has been investigated, studies evaluating the efficacy of the association between these techniques are still needed. OBJECTIVE: To evaluate the activation of the lumbar region muscles by PBM or MT associated with kinesiotherapy for the treatment of LBP. METHODS: Twenty individuals with chronic LBP were randomlydivided into two groups. The first group (MT) received vertebral mobilization associated with a kinesiotherapy exercise program. The second group (830nm-PBM) received PBM associated with the exercise program, twice a week for 8 weeks. Evaluation of pain perceived was performed by the visual analogic scale (VAS), lumbar disability by the Oswestry questionnaire, muscle strength by strain gauge, and activation through surface electromyography (EMG). Data were collected before and after the treatment. EMG data was analyzed by MatLab®. The ANOVA two-way test was used (degree of significance p≤0.05), and the size of the effect by the Hedge test. RESULTS: Considering pain, the two groups presented a significant result (p<0.05). In muscle activation, only the multifidus was different during the side bridge (p<0.05) when compared intragroup. None of the variables were different when evaluating intergroup. CONCLUSION: Both MT and PBM associated with kinesiotherapy for 8 weeks are effective in reducing pain, and improving motor control and stability of the lumbar spine in patients with chronic LBP.

ABSTRACT

INTRODUCTION: The skin flap is a surgical technique widely used in clinical practice and generally presents postoperative complications. Therefore, elucidating interventions that assist in tissue conservation is essential. Photobiomodulation (PBM) and therapeutic ultrasound (TUS) are non-invasive alternatives for assisting tissue repair, however, there is no consensus on the parameters used. OBJECTIVE: To describe the effectiveness of the different parameters of PBM and TUS in the viability of the dorsal random pattern skin flap in mice. METHODS: Fifty-five Swiss mice were used, distributed in eleven groups. The animals were submitted to surgical technique including revascularization of the area limited through a plastic barrier (polyester/polyethylene) with the same dimension as the flap. PBM or TUS was applied for five consecutive days. Photographic and thermographic recordings were performed with Cyber-Shot DSC-P72 and FlirC2 cameras and analyzed using the ImageJ® and FLIR Tools software, respectively. In the statistical analysis, the data were submitted to the GraphPad Prism® 8.0 software. Analysis of variance (ANOVA Two-way) and Tukey's post-test was performed, considering 5% significance level. RESULTS: Groups 5 (PBM830 nm; 10 J/cm²) and 6 (TUS 3 MHz; 0.4 W/cm²) showed percentages of viable tissue significantly higher on the third and fifth day of the experiment, when compared to the other groups. The temperature decreased significantly in group 1 when compared to the others in the postoperative period. CONCLUSION: The continuous TUS at 3 MHz and PBM 830 nm were more effective in improving the viability of the dorsal random pattern skin flap in mice.


INTRODUÇÃO: O retalho cutâneo é uma técnica cirúrgica amplamente empregada na prática clínica e comumente apresenta complicações pós-operatórias. Portanto, elucidar intervenções que auxiliem na conservação do tecido são fundamentais. A fotobiomodulação (FBM) e o ultrassom terapêutico (UST) são alternativas não invasivas que auxiliam no reparo tecidual, contudo, ainda não há consenso sobre os parâmetros a serem utilizados. OBJETIVO: Descrever a efetividade dos diferentes parâmetros da FBM e do UST na viabilidade do retalho cutâneo randômico dorsal em camundongos. MÉTODOS: Utilizou-se 55 camundongos Swiss, distribuídos em onze grupos. Os animais foram submetidos à técnica cirúrgica com a revascularização da área limitada através de uma barreira plástica (poliéster/polietileno) da mesma dimensão do retalho. Aplicou-se a FBM ou UST durante cinco dias consecutivos. O registro fotográfico e termográfico foi realizado com as câmeras Cyber-Shot DSC-P72 e FlirC2, sendo posteriormente analisados nos softwares ImageJ® e FLIR Tools, respectivamente. Na análise estatística, os dados foram submetidos ao software GraphPad Prism® 8.0 e ao teste Shapiro-Wilk para a análise da normalidade. Realizou-se a análise de variância (ANOVA Two-way) e pós-teste de Tukey, com nível de significância de 5%. RESULTADOS: Os grupos 5 (FBM 830 nm; 10 J/cm²) e 6 (UST 3 MHz; 0,4W/cm²) apresentaram porcentagens de tecido viável significativamente maiores no terceiro e quinto dia do experimento. A temperatura reduziu significativamente no grupo-1 quando comparado aos demais no pós-operatório. CONCLUSÃO: O UST contínuo a 3 MHz e FBM 830 nm, foram mais eficazes melhorando a viabilidade a do retalho cutâneo randômico dorsal em camundongos.

ABSTRACT

Introducción: El láser de baja potencia tiene un amplio uso en la práctica médica actual. Existe un gran número de pacientes con afecciones agudas o crónicas que pueden ser tratados con esta terapia, con resultados alentadores, muy superiores a los obtenidos con el uso de la terapéutica convencional. Objetivo: Evaluar la efectividad del láser de baja potencia como terapia adyuvante para reducir el tiempo de respuesta al alivio del dolor en pacientes con herpes zóster. Métodos: Se realizó un estudio cuasiexperimental, de intervención terapéutica, en 21 pacientes con herpes zóster, atendidos en el Servicio de Fisiatría del Policlínico del MININT de Santiago de Cuba, desde enero de 2016 hasta junio de 2017. Se conformaron 2 grupos de forma aleatoria: los integrantes del primero recibieron el tratamiento habitual con aciclovir, vitaminas y analgésico (control); los del segundo, aciclovir, vitaminas y laserterapia (intervención). Resultados: Se observó que en el grupo de intervención la intensidad del dolor fue disminuyendo en relación con la evaluación inicial. Así, en la quinta sesión se apreció mayor porcentaje de pacientes con alivio del dolor que en el grupo control, al igual que en la décima sesión y 21 días después, de ahí la efectividad del tratamiento. Conclusiones: Con el empleo del láser de baja potencia los pacientes con herpes zóster presentaron una mejoría del dolor en menor tiempo, con una respuesta satisfactoria expresada en la totalidad de ellos, por lo que se recomienda su utilización como terapia adyuvante.


Introduction: The low power laser has a wide use in the current medical practice. There is a great number of patients with acute or chronic conditions that can be treated with this therapy, with encouraging results, far better than those obtained with the use of conventional therapy. Objective: To evaluate the effectiveness of low power laser as adjuvant therapy to reduce the response time to pain relief in patients with zoster herpes. Methods: A quasi-experiment study of therapeutic intervention was carried out in 21 patients with zoster herpes. They were assisted in the Physical Medicine Service of the MININT Polyclinic in Santiago de Cuba, from January, 2016 to June, 2017. Two groups were conformed at random: the members of the first one received acyclovir, vitamins and lasertherapy (intervention); those of the second group received acyclovir, vitamins and analgesic (control). Results: It was observed that in the intervention group the intensity of the pain was diminishing in connection with the initial evaluation. This way, in the fifth session it was appreciated a higher percentage of patients with pain relief that in the control group, the same as in the tenth session and 21 days later, hence the effectiveness of the treatment. Conclusions: With the use of low power laser the patients with zoster herpes presented an improvement of the pain in less time, with a satisfactory response expressed in all of them, reason why its use is recommended as adjuvant therapy.

ABSTRACT

Introducción: El dolor es el principal síntoma que refieren los pacientes después de la colocación y activación de los aparatos ortodóncicos. Objetivo: Evaluar la efectividad del láser de baja potencia en el alivio del dolor en pacientes con tratamiento de ortodoncia. Métodos: Se realizó un estudio cuasiexperimental de intervención terapéutica en 30 pacientes que se encontraban en los inicios de la fase de distalización de los caninos superiores (previa extracción de los primeros premolares de la misma arcada), los cuales fueron atendidos en el Servicio de Ortodoncia del Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba, de enero a diciembre de 2020. A tal efecto, se conformaron 2 grupos de forma aleatoria, por el orden de llegada, de 15 integrantes cada uno: el de estudio, que fue tratado con láser de baja potencia, y el de control, que recibió paracetamol como analgésico habitual. Para la validación estadística de la información se emplearon el porcentaje y la prueba de la T de Student para muestras independientes, con 95 % de confiabilidad. Resultados: Existieron diferencias significativas en cuanto a la remisión de la intensidad del dolor, pues el síntoma estuvo ausente o en grado leve en todos los integrantes del grupo de estudio luego de tres sesiones terapéuticas (p=0,00), mientras que solo 13,3 % de los pacientes del grupo de control se ubicaron en estas dos categorías. Conclusiones: Se demostró que la terapia alternativa con láser fue más efectiva para paliar el dolor que el paracetamol.


Introduction: The pain is the main symptom that patients refer after placing and activation of the orthodontic appliances. Objective: To evaluate the effectiveness of the low power laser for pain relief in patients with orthodontics treatment. Methods: A quasi-experiment study of therapeutic intervention was carried out in 30 patients that were in the beginnings of the distancing phase of the upper canine teeth (previous extraction of the same arch first premolars), who were assisted in the Orthodontics Service of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba, from January to December, 2020. To such an effect, 2 groups were conformed at random, by arrival order, of 15 members each one: the study group that was treated with low power laser, and the control group that received paracetamol as usual analgesic. For the statistical validation of the information the percentage and the Student´s t test were used for independent samples, with 95% of confidence. Results: There were significant differences as for the remission of pain intensity, because absence of this symptom or light pain was observed in all the members of the study group after three therapeutic sessions (p=0.00) while just 13.3 % of the control group patients was located in these two categories. Conclusions: It was demonstrated that the alternative therapy with laser was more effective to palliate the pain than the paracetamol.

ABSTRACT

SUMMARY: Laser photobiomodulation (laser PBM) is known to be able to accelerate burn wound healing in the animal model; however little evidence exists on the action of laser PBM on the expression of important proteins in wound healing in the animal model, such as VEGF and TGF-ß1. The aim of this study was to carry out a systematic review in order to analyse the effect of laser PBM on VEGF and TGF-ß expression during burn wound repair in the animal model. A systematic review was carried out of the EMBASE, PubMed/ MEDLINE and LILACS databases. The studies included were preclinical studies that analysed the action of laser PBM on the expression of VEGF and TGF-ß (1, 2, 3) during burn wound repair in the animal model. The SYRCLE risk of bias tool was used. Random effect models were used to estimate the combined effect. Increased VEGF expression was observed with the use of laser PBM at 4.93 J/cm2 per point in the first two weeks after induction of the burn wound, with greater size of effect in the second week (SDM = 5.72; 95% CI: 3.14 to 8.31, I2 = 0 %; very low certainty of evidence). We also observed that the effect of laser PBM on TGF-ß1 expression was greater than in the control in the first week (SDM = -0.45; 95% CI: -1.91 to 1.02, I2 = 51 %; very low certainty of evidence), but diminished in the third week after induction of the lesion (SDM = -2.50; 95% CI: 3.98 to -1.01, I2 = 0 %; very low certainty of evidence). Laser PBM has an effect on TGF-ß1 and VEGF expression, promoting burn wound repair in the animal model.


RESUMEN: Es sabido que la fotobiomodulación por láser (FBM láser) puede acelerar el proceso de curación de heridas por quemadura en modelo animal, sin embargo aún se carece de mayor evidencia sobre la acción de la FBM láser en la expresión de proteínas importantes en el proceso de curación de heridas en modelo animal, como VEGF y TGF-ß1. Así, el objetivo de este estudio fue realizar una revisión sistemática a fin de analizar el efecto de la FBM láser sobre la expresión de VEGF, TGF-ß durante el proceso de reparación de heridas por quemadura en modelo animal. Se realizó una búsqueda sistemática en las bases de datos EMBASE, PubMed/MEDLINE y LILACS. Se incluyeron estudios preclínicos que analizaron la acción de la FBM láser en la expresión de VEGF, TGF-ß (1, 2, 3) durante el proceso de reparación de heridas por quemadura en modelo animal. Se utilizó la herramienta de riesgo de sesgo SYRCLE. Se utilizaron modelos de efectos aleatorios para estimar el efecto combinado. Observamos aumento de la expresión de VEGF con el uso de FBM láser 4.93 J/cm2 por punto, en las dos primeras semanas tras inducción de la herida por quemadura, con mayor tamaño de efecto en la segunda semana (SDM = 5,72; IC del 95%: 3,14 a 8,31, I2 = 0 %; certeza de la evidencia muy baja). También se observó el efecto de la FBM láser en la expresión del TGF- ß1 que fue mayor que el control en la primera semana (SDM = - 0,45; IC del 95%: -1,91 a 1,02, I2 = 51 %; certeza de la evidencia muy baja), disminuyendo en la tercera semana tras inducción de la lesión (SDM = -2,50; IC del 95%: -3,98 a -1,01; I2 = 0 %; certeza de la evidencia baja). La TFB por láser ejerce influencia en la expresión de TGF-ß1 y VEGF favoreciendo el proceso de reparación de heridas por quemadura en modelo animal.

ABSTRACT

A tendência da Odontologia é a incorporação de métodos menos invasivos.Por isso, acredita-se que a terapia a laserde baixa intensidade (TLBI) seja uma opção de tratamento, na medida em que apresenta efeitos benéficos comprovados. O presente estudo tem o objetivo de traçar o padrão de ensino e a percepção dosprofessores sobre o uso de terapia a laserde baixa intensidade no curso degraduação em Odontologia da Universidade Federal do Espírito Santo.Além disso, busca analisar a presença da disciplina de laserterapia nos cursos de Odontologia brasileiros.A pesquisa foi realizada a partir de um estudo analítico, transversal e descritivo, com a aplicação de um questionário a44 professores da Odontologiada Universidade Federal do Espírito Santo. A partir deste estudo obteve-se que 9% de todo corpo docente afirmou utilizar o laserem alguma das atividades das disciplinasque ministram, sendo que esta baixa porcentagem foi justificada pelos professores devido à falta de recurso financeiro para obtenção dos aparelhos. Foi observado que a maior parte do corpo docente já teve conhecimento sobre o laser, sendo 45,4% durante a pós-graduação. Quando avaliada a estrutura curricular das 461instituições de ensino superior brasileiras de Odontologia em atividade, 13 oferecem a disciplina de laserterapia em sua matriz curricular.Pode-se concluir que existe um considerável nível de conhecimento sobre o laserentre os docentes. Porém, nota-se pouca disseminação de informação nas diferentes disciplinas do curso estudado (AU).


There is a tendency in Dentistry to incorporate less invasive methods of treatment. Therefore, since it has proven beneficial effects, it is believed that low-intensity laser therapy (LILT) can be a treatment option. The objective of this study is to outline the teaching pattern and perception of professors about their knowledge in the use of low -intensity laser therapy in Dentistry at the Federal University of Espírito Santo. In addition, it seeks to analyze the presence of Laser Therapy programs in the Dentistry Schools in Brazil. The research was carried out from an analytical, transversal and descriptive study. A questionnaire was applied to 44 professors of the course of Dentistry at the Federal University of Espírito Santo. From this study, it was found that 9% of all professors claimed to use the laser in some of the teaching activities. This percentage was justified by then due to the lack of financial resources to obtain the devices. It was observed that most of the professors had knowledge about the laser. According to 45.4% of then, this knowledge was acquired during the post-graduation. When evaluating the curricular structure of the courses of Dentistry at Brazilian Universities it was found that from the 461 in activity, 13 offer the disciplineof laser therapy. It can be concluded that there is a considerable level of knowledge about the laser among professors. However, there is little knowledge transmission in the different disciplines of the course studied (AU).

ABSTRACT

Introduction: Transcutaneous electrical nerve stimulation (TENS), interferential current therapy (IFC) and photobiomodulation therapy (PBMT) have been used in the management of cancer-related pain in adults. However, there are still some controversy regarding the effects of this therapy on tumor cells that may remain after cancer treatment. Objective: To evaluate the risk of recurrence of breast cancer in rats when using TENS, IFC or PBMT. Method: An experimental, randomized, controlled and cross-sectional study. With 90 days of age, 7,12-dimetylbenz(a)anthracene (7,12-DMBA) was administered to rats by gastric gavage to induce mammary cancer. After 120 days the mammary glands of the rats belonging to the group with mammary cancer were removed. Results: 39 female Sprague-Dawley rats were studied: 9 rats without induction of mammary carcinoma; 9 rats with induction of mammary carcinoma and without surgery; 9 rats with induction of mammary carcinoma with surgery and placebo application of TENS, IFC, PBMT; 9 rats with induction of mammary carcinoma, surgery and the application of TENS, IFC and PBMT. Conclusion: This study demonstrated that there was local recurrence of tumors in rats that were stimulated with TENS or IFC, however no evidence of local recurrence with PBMT

ABSTRACT

The association of scaffolds to repair extensive bone defects can contribute to their evolution and morphophysiological recomposition. The incorporation of particulate biomaterials into three-dimensional fibrin bioproducts together with photobiomodulation therapy (PBM) has potential and can improve regenerative medicine procedures. The objective of this experiment was to evaluate the effects of PBM therapy on critical size defects filled with xenogenic bone substitute associated with fibrin biopolymer. Methods: A critical defect of 8 mm was performed in 36 Wistar male adult rats that were divided into four groups. Groups BC and BC-PBM were defined as controls with defects filled by a clot (without or with PBM, respectively) and groups XS and XS-PBM that comprised those filled with biocomplex Bio-OssTM in association with fibrin biopolymer. PBM was applied immediately after the surgery and three times a week every other day, with the parameters: wavelength of 830 nm, energy density 6.2 J/cm2, output power 30 mW, beam area of 0.116 cm2, irradiance 0.258,62 W/cm2, energy/point 0.72 J, total energy 2.88 J. Fourteen and 42 days after the surgery, animals were euthanatized and subjected to microtomography, qualitative and quantitative histological analysis. Results: The BC-PBM and XS-PBM groups had a similar evolution in the tissue repair process, with a higher density of the volume of new formed bone in relation to the groups without PBM (p = 0.04086; p = 0.07093, respectively). Intense vascular proliferation and bone deposition around the biomaterial particles were observed in the animals of the groups in which biocomplex was applied (XS and XS-PBM). Conclusion: PBM therapy allowed an improvement in the formation of new bone, with a more organized deposition of collagen fibers in the defect area. Biocomplex favored the insertion and permanence of the particulate material in bone defects, creating a favorable microenvironment for accelerate repair process.(AU)
