Avaliação da efetividade da estimulação neural elétrica por microcorrente (MENS) na dor muscular em pacientes com desordem temporomandibular

The effect of Microcurrent Electrical Nerve Stimulation (MENS) was evaluated and compared with occlusal splint therapy in temporomandibular disorders (TMD) patients with muscle pain. Twenty TMD patients were divided into four groups. One received occlusal splint therapy and MENS (I); other received splints and placebo MENS (II); the third, only MENS (III) and the last group, placebo MENS (IV). Sensitivity derived from muscle palpation was evaluated using a visual analogue scale. Results were submitted to analysis of variance (pA efetividade da Estimulação Neural Elétrica por Microcorrente (MENS) foi avaliada e comparada à terapia por Placas Oclusais em pacientes com desordens temporomandibulares (DTM) de origem muscular.

Avulsion of permanent teeth: analysis of the efficacy of na informative campaign for professionals from elementary schools

Tooth avulsion is a very common event in children and emergency care procedures are crucial for case prognosis. As anyone at the moment of accident can provide first-aid measures, knowledge of school professionals dealing with children is of paramount importance. An informative campaign about dental trauma was performed in urban schools in the city of Adamantina, São Paulo state, Brazil, in an attempt to educate school professionals about emergency procedures in cases of tooth avulsion. A questionnaire arguing on personal information, tooth avulsion knowledge and personal impressions of the campaign was handed out for evaluation of the informative campaign. Eighty school professionals participated in the survey. Most participants were females (93.75%) aged 41-60 years old (53.75%) with a college degree (77.5%). Time at work ranged from 1-5 years (22.5%). The efficacy of the campaign was considered positive, as 100% of the interviewees replied to the importance of emergency procedures in case of tooth avulsion. In addition, 81.25% of the respondents answered that they would store the avulsed tooth in some storage medium, of which milk was the most frequently mentioned (84.61%). The participants considered the campaign as satisfactory and a region-wide campaign will be accomplished at other schools

Impact event and orofacial pain amid the COVID-19 pandemic in Brazil: a cross-sectional epidemiological study

Objectives: This study aims to assess the impact of social isolation, due to the Covid-19 pandemic, on mental health, Temporomandibular Disorder (TMD) and orofacial pain in men and women. Methodology: Individuals living in Brazil answered an online questionnaire on their sociodemographic and behavioral aspects, emotional scale (DASS-21), Impact of Event Scale, and Pain Screener in Temporomandibular Disorders (TMD-Pain Screener) during June 2020. Descriptive statistical analyses and logistic and linear regressions were applied (5% significance). Results: Overall, 2301 individuals were included, 89.1% practiced social isolation, 72.6% were employed/studying, at least 15% presented severe or extremely severe levels of emotional distress and presence of powerful (34.1%) and severe impact event (15%). During the outbreak, 53.2% perceived feeling worse and 31.8% reported that orofacial pain started or worsened after the pandemic outbreak. Gender was associated with “social class” (P=0.036), “pain/stiffness in the jaw on awakening” (P=0.037), “change of pain during jaw habits” (P=0.034) and “perception of change in the situations mentioned in the TMD-Pain Screener” (P=0.020), “depression” (P=0.012), “anxiety” (P=0.006) and “impact of the event” (P=8.3E-11). Social isolation had a lesser chance to change the routine, to be practiced by the unemployed/not studying, and to be practiced by men (all with P<0.001). Associations were found between social class and all subscales of the DASS-21 and IES, all with P<0.001. Conclusions: The practice of social isolation has social determinants. High levels of psychological and event impacts were detected. The presence of orofacial pain seemed to increase during the health crisis, and there were gender differences in the response to the COVID-19 pandemic

Comparative analysis of reflection photoelasticity in mandible’s segment with or without base

Introduction and Objective: To analyze if axial loads of 50 N and 100 N, applied on an implant of 3.75 X 10 mm (Conexão-Jaú, SP, Brazil) fixed on the central portion of a prototype of the mandible with and without support base, generate isochromatic fringes of different intensity and ways. Material and methods: The sample was a segment of the mandible with 115 mm in length, 30 mm height,and 12 mm in thickness, from a block of #7 rose wax. This matrix was adapted to a modified articulator in such way that its base could or not keep contact with the lower arm of the articulator, simply by modifying the support axis. An implant was put perpendicular to the segment of the mandible’s body and then the photoelastic model obtained. The healing abutment was screwed to the implant to receive loads from 50 N to 100 N, with the model with or withoutcontact of its base with the inferior arm of the articulator. Results: Alterations in the reflections of the colors was observed when the implants had been submitted to loads of 50 N and 100 N with or without supported base. Conclusion: Based on the results, it can be concluded that during the photoelasticity analyses alterations in the color standards occurred depending on the support of the sample and the applied load.Introduction and Objective: To analyze if axial loads of 50 N and 100 N, applied on an implant of 3.75 X 10 mm (Conexão-Jaú, SP, Brazil) fixed on the central portion of a prototype of the mandible with and without support base, generate isochromatic fringes of different intensity and ways.

Effect of Photobiomodulation Combined with Physiotherapy on Functional Performance in Children with Myelomeningo-Cele-Randomized, Blind, Clinical Trial.

peer reviewed[en] BACKGROUND: This study aimed to evaluate the electrical activity of the rectus femoris, tibialis anterior, and lateral gastrocnemius muscles during the sit-to-stand task and functional mobility after a neurofunctional physiotherapy protocol associated with PBM. METHODS: Twenty-five children were randomly allocated to either Active PBM + physiotherapy (n = 13) or PBM sham + physiotherapy (n = 12). PBM was carried out with a LED device (850 nm, 25 J, 50 s per point and 200 mW) at four points over the area with absence of a spiny process. Both groups completed a twelve-week supervised program with two weekly 45-60 min sessions. Pre-training and post-training assessments involved the Pediatric Evaluation of Disability Inventory (PEDI). Muscle activity was assessed using portable electromyography (BTS Engineering) and the electrodes were positioned on the lateral gastrocnemius, anterior tibialis, and rectus femoris muscles. The RMS data were recorded and analyzed. RESULTS: After 24 sessions of the treatment protocol, improvements were found in the PEDI score. The participants presented greater independence in performing the tasks, requiring less assistance from their caregivers. More significant electrical activity was found in the three muscles evaluated between the rest period and execution of the sit-to-stand tasks, both in the more compromised or less compromised lower limbs. CONCLUSION: Neurofunctional physiotherapy with or without PBM improved functional mobility and electrical muscle activity in children with myelomeningocele

Sensibilidade à pressão e atividade elétrica dos músculos temporal e masseter durante o ciclo menstrual de mulheres que fazem e não o uso contraceptivo oral

A alta prevalência dos sintomas das desordens temporomandibulares (DTMs) em mulheres tem sido relacionada com a influência dos hormônios reprodutivos femininos. Isto sugere a ação dos hormônios sexuais como um fator coadjuvante no aparecimento das DTMs. Diante disto, o objetivo deste trabalho foi avaliar a dor à pressão digital e algométrica, bem como a atividade elétrica do temporal e masseter durante o ciclo menstrual de um grupo de jovens. Para isto, foram avaliadas 28 mulheres, entre 18 e 32 anos, sendo que 15 delas não faziam uso de contraceptivo oral e 13 eram usuárias deste medicamento. Todas as mulheres foram avaliadas por meio de questionário, palpação digital e algométrica, e submetidas a registros eletromiográficos dos músculos temporal e masseter durante três ciclos menstruais consecutivos. Os resultados não apresentaram variações na sensibilidade à pressão entre as fases do ciclo menstrual, bem como entre os grupos. A atividade elétrica foi estatisticamente mais elevada no músculo temporal apenas durante a mastigação (lado de trabalho) naquelas que faziam uso de contraceptivo oral, mas não houve diferença entre as fases dentro de cada grupo.High prevalence of signs and symptoms of TMD in women has been related to sexual hormones. It suggests that sexual hormones can influence the beginning of Temporomandibular Disorders. The aim of this study was study sensibility to palpation and pressure-pain threshold of the temporal and masseter muscles, as well as electrical activity across menstrual cycle in young adults women. Twenty eight women participated in this study, 15 of them weren t oral contraceptive users, and another 13 were users of this medication. All of them answered questionnaires and were submitted to palpation, algometry and electromyographic exams of temporal and masseter muscles across three consecutives menstrual cycles. The results showed that sensibility to pain weren t different between phases and groups. However, the electrical activity of temporal (in the side of chewing) was significantly elevated in contraceptive users during chewing but not during rest in all phases. It didn t occur variation across cycle within each group.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES
