ABSTRACT

COVID-19 pandemic can have a significant impact on an individual's physical and emotional well-being. However, it is important to note that not all experiences of the pandemic are negative. This study aims to evaluate the perception of quality of life of students enrolled in a nursing course during the COVID-19 pandemic by administering a global questionnaire. A quantitative, exploratory, cross-sectional, and descriptive study to investigate perception of quality of life of students during the COVID-19 pandemic. Participants comprised 80 students graduating with a nursing qualification between 2020 and 2021. The Ferrans and Powers Quality of Life Index was used in the study. The mean scores are reported as follows: health/functioning domain (22.06), socioeconomic domain (21.40), psychological/spiritual domain (23.34), and family domain (23.06), with an average general quality of life index of 22.46. After evaluating the domains, it was found that there was a higher perception of the psychological/spiritual domain and lower perception of the socioeconomic domain. The results supported the internal consistency reliability of the entire Quality of Life (QLI; alpha=0.95) and the four subscales (alpha=0.88, 0.71, 0.92, and 0.80). The study suggests that the COVID-19 pandemic did not have an impact on the perceived quality of life among students.(AU)


Pandemia de COVID-19 pode ter um impacto significativo no bem-estar físico e emocional de um sujeito. No entanto, é importante notar que nem todas as experiências da pandemia são negativas. Este estudo teve como objetivo avaliar a percepção da qualidade de vida de estudantes matriculados em um curso de enfermagem durante a pandemia de COVID-19 por meio da aplicação de um questionário global. Estudo quantitativo, exploratório, transversal e descritivo para investigar a percepção da qualidade de vida de escolares durante a pandemia de COVID-19. Participaram 80 estudantes concluintes do curso de enfermagem entre 2020 e 2021. O Índice de Qualidade de Vida de Ferrans e Powers foi utilizado no estudo. Os escores médios foram relatados da seguinte forma: domínio saúde/funcionamento (22,06), domínio socioeconômico (21,40), domínio psicológico/espiritual (23,34) e domínio família (23,06), com média geral do índice de qualidade de vida de 22,46. Após a avaliação dos domínios, constatou-se maior percepção do domínio psicológico/espiritual e menor percepção do domínio socioeconômico. Os resultados apoiaram a confiabilidade da consistência interna de toda a Qualidade de Vida (QLI; alfa=0,95) e as quatro subescalas (alfa=0,88, 0,71, 0,92 e 0,80). O estudo sugere que a pandemia de COVID-19 não teve impacto na qualidade de vida percebida entre os estudantes.(AU)

ABSTRACT

Low-level laser therapy has been investigated as a possible stimulus for enhancement of proliferation and differentiation of various cell types, but few reports relate undifferentiated mouse pulp cells (OD-21) response to irradiation in in vitro models. The aim of this study was to analyze the influence of low-level laser therapy (λ=660 nm), with three different irradiation times, on the behavior of OD-21 cell line. The cells were cultivated and divided into three groups: non-irradiated/control (group I); irradiated with 88 s (group II); irradiated with 177 s (group III) and irradiated with 265 s (group IV). Cell growth and viability were assessed after 7 and 10 days. Data were analyzed by Kruskal-Wallis and MannWhitney tests (α=.05). At day 7, there was a higher cell growth in groups I and II, as compared to group IV (p<.01). At the 10th day, group I showed a higher cell growth as compared to group II (p<.05). Cell viability in group IV was significantly lower at the 7th day, as compared to groups I (p<.001), II (p<.01) and III (p<.001). Cell viability in all the groups was over 80%, except in group IV at day 7. Irradiation time of group I influenced positively the proliferation and viability of OD-21 cells in late cell culture period. (AU)


A terapia a laser de baixa intensidade tem sido investigada como possível estímulo para aumento da proliferação e diferenciação de vários tipos de células, mas poucos relatos relacionam a resposta de células indiferenciadas da polpa dentária de camundongos (OD-21) à irradiação em modelos in vitro. O objetivo deste estudo foi analisar a influência do laser de baixa intensidade (λ=660 nm), com três períodos de irradiação diferentes, no comportamento das células da linhagem OD-21. As células foram cultivadas e distribuídas em três grupos: não irradiado / controle (grupo I); irradiado com 88 s (grupo II); irradiado com 177 s (grupo III) e irradiado com 265 s (grupo IV). O crescimento e a viabilidade celular foram avaliados após 7 e 10 dias. Os dados foram analisados pelos testes de Kruskal-Wallis e Mann-Whitney (α = 0,05). No dia 7, houve crescimento celular maior nos grupos I e II, em comparação ao grupo IV (p <0,01). No décimo dia, o grupo I apresentou crescimento celular superior ao grupo II (p <0,05). A viabilidade celular no grupo IV foi significativamente menor no sétimo dia, em comparação aos grupos I (p <0,001), II (p <0,01) e III (p <0,001). A viabilidade celular em todos os grupos foi superior a 80%, exceto no grupo IV no dia 7. O tempo de irradiação do grupo I influenciou positivamente a proliferação e a viabilidade das células OD-21 no período mais tardio da cultura celular.A terapia a laser de baixa intensidade tem sido investigada como possível estímulo para aumento da proliferação e diferenciação de vários tipos de células, mas poucos relatos relacionam a resposta de células indiferenciadas da polpa dentária de camundongos (OD-21) à irradiação em modelos in vitro.

ABSTRACT

This case report evaluated electromyographic activity of the masseter and temporalis muscles and molar bite force, before and after with functional orthopedic. A 65 years woman presenting with orofacial pain symptoms, cervical tension, condyle subluxation and osteoarthrosis. The patient was diagnosed with temporomandibular dysfunction and treated with use of a Simões Network 9 modified type functional maxillary orthopedics appliance. The Myosystem BR1 apparatus was used to analyze the electromyographic activity of the masseter and temporalis muscles. The maximum molar bite force was measured with the digital dynamometer (Kratus). This study showed increased EMG activity of the masseter and temporalis muscles in postural conditions of mandible and molar bite force after 12 months of treatment. After twelve months of treatment, the patient had lack of pain symptoms as well as an improvement in the balance of the mastication muscles, as demonstrated by EMG activity and maximum molar bite force.

ABSTRACT

Assess whether the Lucia Jig is a device that promotes masticatory muscle relaxation in individuals with temporomandibular dysfunction. This study was carried out in three stages (interviews, clinical examination, and laboratory) and participation of adult individuals, between 21 and 40 years of age, of both genders, who replied to the RDC/TMD questionnaire to diagnose muscular temporomandibular dysfunction. The Lucia Jig was prepared and electromyographic examination of the masseter and temporal muscles was performed bilaterally, in the postural condition of the mandibular at rest, after immediately installing the Lucia Jig in the oral cavity and at periods of 5, 10, 15, 20, and 30 min. The values obtained were compared using repeated measures (p < 0.05) over the entire duration of the experiment (0 to 30 min) with the Lucia Jig. There was an increase in the normalized electromyographic signal of the masticatory muscles, with the use of the Lucia Jig over the period of 30 min, with no statistically significant difference. Based on the results of this study through electromyographic data, the device did not promote masticatory muscle relaxation in individuals with muscular temporomandibular dysfunction.


Avaliar se o Jig de Lucia é um dispositivo que promove relaxamento dos músculos mastigatórios em indivíduos com disfunção temporomandibular. O estudo foi realizado em três etapas (entrevista, exame clínico e laboratorial) com a participação de indivíduos adultos, entre 21 e 40 anos de idade, ambos os gêneros, que responderam ao questionário RDC/TMD para diagnosticar disfunção temporomandibular muscular. O Jig de Lucia foi confeccionado e o exame eletromiográfico foi realizado nos músculos masseter e temporal, bilateralmente, na condição postural da mandíbula em repouso e imediatamente depois da instalação do Jig de Lucia na cavidade oral nos períodos de 5, 10, 15, 20 e 30 min. Os valores obtidos foram comparados ao longo de toda a duração do experimento (0 a 30 min) com o Jig de Lucia, utilizando o teste de medidas repetidas (p <0,05). Houve aumento no sinal EMG normalizado dos músculos da mastigação, com o uso do Jig de Lucia ao longo do período de 30 min, sem diferença estatística significante. Com base nos resultados deste estudo, conclui-se que o dispositivo Jig de Lucia, por meio dos dados eletromiográficos, não promove relaxamento dos músculos mastigatórios em indivíduos com disfunção temporomandibular muscular.

ABSTRACT

The aim of this study was to examine the bite force and masseter and temporal muscle thickness in individuals with maxillary and mandibular osteoporosis. 72 individuals were distributed into two equal groups: (1) facial osteoporosis and (2) healthy controls. Bite force on the right and left molar regions was recorded with a dynamometer and the highest value out of three measurements was recorded as the maximal bite force. Muscle thickness was measured with a SonoSite Titan ultrasound scanner. Ultrasound images were obtained of the bilateral masseter and temporal muscles at rest and at maximal voluntary contraction. The means of the measurements in each clinical condition were analyzed with multivariate statistical analysis (SPSS 19.0). Student's t test indicated no significant difference for muscle thickness, but indicated significantly lower bite force values in the osteoporosis group (p>0.05). Lower bite force in individuals with facial bone loss demonstrates functional impact of osteoporosis on the complex physiological stomatognathic system.


Este estudo teve como objetivo analisar a forca de mordida e a espessura dos musculos masseter e temporal em individuos com osteoporose maxilar e mandibular. 72 individuos distribuidos em dois grupos equivalentes: (1) osteoporose facial e (2) controles saudaveis. Forca de mordida nas regioes de molar direita e esquerda foi gravada com o dinamometro e o valor mais alto das tres medidas foi registrado como a forca de mordida maxima. A espessura muscular foi mensurada com ultrassom SonoSite Titan. As imagens de ultrassom foram obtidas dos musculos masseter e temporais bilateral em repouso e em contracao voluntaria maxima. As medias das medidas em cada condicao clinica foram analisadas com a analise estatistica multivariada (SPSS 19.0). Teste t de Student nao revelou diferencas significativas para a espessura musculos, mas indicou valores significativamente mais baixos de forca de mordida no grupo com osteoporose (p> 0,05). Forca de mordida menor em individuos com perda ossea facial demonstra um impacto funcional da osteoporose na fisiologia complexa do sistema estomatognatico.

ABSTRACT

The Lucia jig is a technique that promotes neuromuscular reprogramming of the masticatory system and allows the stabilization of the mandible without the interference of dental contacts, maintaining the mandible position in harmonic condition with the musculature in normal subjects or in patients with temporomandibular dysfunction (TMD). This study aimed to electromyographically analyze the activity (RMS) of the masseter and temporal muscles in normal subjects (control group) during the use of an anterior programming device, the Lucia jig, in place for 0, 5, 10, 20 and 30 minutes to demonstrate its effect on the stomatognathic system. Forty-two healthy dentate individuals (aged 21 to 40 years) with normal occlusion and without parafunctional habits or temporomandibular dysfunction (RDC/TMD) were evaluated on the basis of the electromyographic activity of the masseter and temporal muscles before placement of a neuromuscular re-programming device, the Lucia jig, on the upper central incisors. There were no statistically significant differences (p < 0.05) in the electromyographic activity of the masticatory muscles in the different time periods. The Lucia jig changed the electromyographic activity by promoting a neuromuscular reprogramming. In most of the time periods, it decreased the activation of the masticatory muscles, showing that this device has wide applicability in dentistry. The use of a Lucia jig over 0, 5, 10, 15, 20 and 30 minutes did not promote any statistically significant increase in muscle activity despite differences in the data, thus showing that this intra-oral device can be used in dentistry.
