RESUMEN
OBJECTIVES: This study aimed to assess whether awake bruxism and masticatory muscle activity could be related to external root resorption (ERR) in second molars adjacent to impacted mandibular third molars. MATERIALS AND METHODS: Sixty patients, with requests for a cone-beam, computed tomography, were divided into two groups: ERR (patients with ERR in the second molar, n = 30), and control group (n = 30). Awake bruxism was assessed through the Oral Behaviors Checklist (OBC) and an ecological momentary assessment (EMA). Surface electromyography (EMG) was used to assess the masseter and anterior temporal muscle function. Normality and homogeneity of variances were demonstrated. Descriptive analysis was performed, using the T-test and Chi-square test to compare the characteristics of the groups. A multiple regression model was performed. RESULTS: The ERR group presented more non-functional oral activities related to awake bruxism than the control group, according to OBC (p = 0.027) and EMA (p = 0.035). In addition, the ERR group had higher EMG activity than the control group in rest and isotonic protocols (p < 0.05). CONCLUSIONS: Awake bruxism and greater masticatory muscle activity seem to be related to the presence of ERR in second molars adjacent to impacted mandibular third molars. CLINICAL RELEVANCE: The results of the present study can reinforce the theory that triggering ERR in the second molars adjacent to impacted mandibular third molars may be related to mechanical forces coming from the masticatory function.

ABSTRACT: This review presents a comprehensive summary and critical evaluation of intention-to-treat analysis, with a particular focus on its application to randomized controlled trials within the field of rehabilitation. Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we conducted a methodological review that encompassed electronic and manual search strategies to identify relevant studies. Our selection process involved two independent reviewers who initially screened titles and abstracts and subsequently performed full-text screening based on established eligibility criteria. In addition, we included studies from manual searches that were already cataloged within the first author's personal database. The findings are synthesized through a narrative approach, covering fundamental aspects of intention to treat, including its definition, common misconceptions, advantages, disadvantages, and key recommendations. Notably, the health literature offers a variety of definitions for intention to treat, which can lead to misinterpretations and inappropriate application when analyzing randomized controlled trial results, potentially resulting in misleading findings with significant implications for healthcare decision making. Authors should clearly report the specific intention-to-treat definition used in their analysis, provide details on participant dropouts, and explain upon their approach to managing missing data. Adherence to reporting guidelines, such as the Consolidated Standards of Reporting Trials for randomized controlled trials, is essential to standardize intention-to-treat information, ensuring the delivery of accurate and informative results for healthcare decision making.

BACKGROUND: There is a high prevalence of musculoskeletal pain and stress levels in university students in the health area. The current study aimed to evaluate the prevalence of pain in the cervical region, lumbar spine, and upper and lower limbs in university students in the final year of physiotherapy; and to determine the correlation between smartphone overuse, stress level, and musculoskeletal pain. METHODS: This is observational cross-sectional study. Students completed an online questionnaire containing sociodemographic information, the Neck Disability Index (NDI), Nordic Musculoskeletal Questionnaire (NMQ), Smartphone Addiction Scale Short-version (SAS-SV), Job Stress Scale, and Oswestry Disability Questionnaire (ODI). The Biserial-point correlation test and Spearman correlationvtest was performed. RESULTS: In total, 42 university students participated in the study. The results indicate a high prevalence of students with cervical pain (83.3%), lumbar pain (76.2%), shoulder (57.1%) and wrist (52.4%). Correlations were found in the comparison of the SAS-SV versus NDI (p < 0.001, R = 0.517) and neck pain (p = 0.020, R = 0.378). The stress scale versus pain in the upper back (p = 0.008, R = 0.348), elbow (p = 0.047, R = 0.347), wrist (p = 0.021, R = 0.406), and knee (p = 0.028, R = 0.323), pain in the wrist versus high scores in the SAS-SV (p = 0.021, R = 0.367), and also hours spent using the smartphone versus pain in the hip (total time: p = 0.003, R = 446; work: p = 0.041, R = 0.345; recreation: p = 0.045, R = 0.308). CONCLUSION: There is a high prevalence of pain in the cervical and lumbar regions in university students in the final year of Physiotherapy. A correlation was found between neck disability, neck and upper back pain and overuse of the smartphone and stress.

OBJECTIVE: To verify the characteristics of the electromyographic signal of masticatory muscles in individuals with TMD and asymptomatic individuals. METHODS: A systematic review was carried out, selecting cross-sectional studies with at least one electromyographic parameter (FM; iEMG; RMS) of the masticatory muscles (anterior temporal, bilateral masseter, and suprahyoid muscles) of individuals with TMD compared to asymptomatic individuals. RESULTS: This review identified 1656 titles, of which 30 articles were included in the final analysis. It was observed that the data referring to the pattern of activation of masticatory muscles in the rest, isometry, and isotonic conditions of individuals with TMD are heterogeneous. This fact may be related to variability in the methods and analyses applied in the studies. CONCLUSION: Data referring to the pattern of activation of masticatory muscles in the rest and isometry conditions and in the mastication cycle of individuals with TMD and asymptomatic individuals are diverse.

Aim: The study aimed to evaluate the accuracy of the maximum bilateral molar bite force and the Root Mean Square (RMS) Electromyography (EMG) index of the masticatory muscles in the maximum bilateral molar bite (MMBMax) of women with myogenic Temporomandibular Disorder (TMD) and asymptomatic. Methods: This is a cross-sectional study, composed of 86 women allocated to the TMD Group (n=43) and Control Group (n=43) diagnosis through the Diagnostic Criteria for Temporomandibular Disorders. The maximum bilateral molar bite force was evaluated using a bite dynamometer and the RMS EMG index of the masticatory muscles (anterior temporalis, masseter) during 5 seconds of the MMBMax task. Student t-test was used for data comparison between accuracy of the bite force and RMS EMG of masticatory muscles during the MMBMax. Results: The maximum bilateral molar bite force showed high accuracy (AUC=0.99) for the diagnosis of women with myogenic TMD and asymptomatic women, and the RMS EMG index evaluated during the MMBMax showed a moderate level of accuracy for all masticatory muscles (AUC=0.70 to 0.75). Conclusion: The bilateral bite dynamometer with a surface EMG during bilateral bite can be used to diagnose TMD in young women

There is no consensus on the most appropriate method for normalizing electromyography (EMG) signals from masticatory muscles during isotonic activity. Aim: To analyze the best method for data processing of the EMG signal of the masticatory muscles during isotonic activity (non-habitual chewing), comparing raw data and different types of normalization. Methods: This is a cross-sectional study. Women aged between 18 and 45 years were selected. Anthropometric data were collected (age, height, body mass index BMI, masticatory preference) as well as EMG signal (root mean square RMS) data for the anterior temporal and masseter bilaterally, and for the suprahyoid muscles, during isotonic (non-habitual chewing) and isometric tasks. EMG data were processed offline using Matlab® Software. The normalization of the EMG signal was carried out using the 2nd masticatory cycle, chosen at random, of the 20 cycles collected, the maximum RMS value, and the maximum voluntary contraction (MVC). To analyze the best method of data processing for the isotonic data, the coefficient of variation (CV) was calculated. Descriptive data analysis was adopted, using the mean and standard deviation. ANOVA with repeated measures was used to detect significant differences between the methods of normalization. Statistical significance was set at 5% (α<0.05). Results: The final sample of this research was composed of 86 women. The volunteers presented an average age of 27.83±7.71 years and a mean BMI of 22.85±1.91 Kg/m2. Regarding masticatory preference, 73.25% reported the right side, and 26.75% the left side. Considering the comparison between the methods, the %CV measure of the 2nd cycle showed the lowest variation coefficient during biting for all the muscles from the raw data, RMS Max, and MVC (p=0.001, p=0.003, and p=0.001 respectively). Conclusion: In conclusion, for non-habitual chewing activity, the results of this study recommend data processing using normalization with the second cycle during chewing

Temporomandibular disorder (TMD) is recognized for its high prevalence, presenting characteristic signs and symptoms. Cervical spine pain is present in 70% of diagnosed TMD cases. Aim To verify if women with TMD present changes in isometric muscle strength in the scapula elevation. Methods This is an observational, cross-sectional study. Thirty-five women, aged 22.89±2.04 years, were divided into the TMD group (TMDG), diagnosed with TMD according to the DC/TMD, and control group (CG), with asymptomatic individuals. The volunteers accessed a online link by the smartphone in order to answer questions on personal data, the Fonseca Anamnestic Index (FAI), Neck Disability Index (NDI), and Masticatory preference. In all participants, evaluation of the force of the scapula elevation muscles was performed, using a load cell model MM-100 (Kratos® SP, Brazil). Data were analyzed descriptively using the maximum, mean, and standard deviation and a two-way ANCOVA test was applied for all variables. A significance level of 5% was considered. Results There were no statistically significant differences between the TMDG and CG for the maximal and mean muscle strength of scapular elevation. There were statistically significant differences in FAI (p <0.001*) between the CG and the TMDG. Conclusion Based on the results, it was not possible to confirm the hypothesis that women diagnosed with TMD present lower isometric strength during scapular elevation (right/left).

BACKGROUND: Excessive use of smartphones may be associated with behavioral and physical health changes and might cause musculoskeletal alterations in the head and neck region. OBJECTIVE: To evaluate the prevalence of smartphone addiction in college students and its correlation with symptoms of head and neck pain and masticatory and trapezius muscle activity while resting, before and after smartphone use. METHODS: Twenty university students participated in the study. They answered the Smartphone Addiction Scale and the Fonseca Anamnestic Index. Next, the participants were seated and prepared for electromyography through the placement of surface electrodes on the masseter, temporal, and trapezius muscles. Rest condition data were collected for 10 seconds before and after 30 minutes of smartphone use. RESULTS: The results showed that 35% of the evaluated individuals were classified as smartphone addicted and 35% reported no head or neck pain in the previous 30 days. There was no association between smartphone use and head and neck pain. In the electromyography, there was an increase in RMS values after smartphone use in the right and left masseter muscles and the left trapezius. CONCLUSION: College students presented a high prevalence of smartphone addiction and head and neck pain, but these were not statistically associated. There was a change in muscle activity only in the right trapezius muscles before and after 30 minutes of smartphone use. These findings are contrary to the current belief that the use of smartphones correlates with pain in the neck region and changes in the electrical muscle activity, leading to fatigue in the cervical muscles.

INTRODUCTION: The use of smartphones is growing every year, and their excessive use can cause adverse physical and mental effects. AIM: This study aimed to evaluate the influence of smartphone use on the median frequency of the masticatory muscles and upper trapezius muscles in healthy women. METHOD: Six healthy young women were evaluated. All the volunteers underwent a submaximal bite test to evaluate their masticatory muscles. In addition, the volunteers underwent a test for bilateral shoulder elevation to a submaximal load to evaluate their upper trapezius muscles. Both protocols were performed before and after a task using the smartphone for 30â¯min. Median frequency (MF) values were collected during the submaximal bite and submaximal shoulder elevation tests. RESULTS: Data were analyzed using specific statistical tests. A statistically significant reduction in the MF for all the masticatory muscles was observed in the bilateral bite task when comparing pre and post smartphone use (pâ¯<â¯0.005). A significant reduction in the MF was also found for the right upper trapezius when comparing pre and post smartphone use in the shoulder elevation task (pâ¯=â¯0.001). CONCLUSION: It appears that prolonged smartphone use may contribute to fatigue in the masticatory and upper trapezius muscles. Therefore, guidelines for smartphone users should include advice on the moderate use of this device.

BACKGROUND: Smartphone use has been constantly increasing. Smartphone addiction can lead to changes in the emotional state and musculoskeletal system of users. To identify smartphone addicts, the Smartphone Addiction Scale-Short Version was developed; however, this scale has not been translated into Brazilian Portuguese and tested for its measurement properties. OBJECTIVE: To translate and cross-culturally adapt the Smartphone Addiction Scale-Short Version into Brazilian Portuguese; to assess the internal consistency, reliability and construct validity of the scale among university students. METHODS: The cross-cultural adaptation was performed following the guidelines for cross-cultural adaptation of self-report measures, and data were collected via online surveys administered to 59 university students over 18 years of age for test-retest. To test the measurement properties of the final version of the Smartphone Addiction Scale-Short Version, a convenience sample including 130 university students was used. RESULTS: The Smartphone Addiction Scale-Short Version showed good reliability for test-retest scores (ICC3,1=0.82; 95% CI=0.70-0.89) and good internal consistency considering all 10 items (Cronbach's alpha=0.95). The construct validity was calculated comparing the Smartphone Addiction Scale-Short Version score to data from a questionnaire prepared by the authors of this study, including frequency per day (r=0.35; p<0.001), leisure time on the smartphone (r=0.33; p<0.001), and time working on the smartphone (r=0.18; p=0.04) that were significantly positively associated with higher Smartphone Addiction Scale-Short Version scores. The results show a high prevalence of smartphone addiction among university students (33.1%). CONCLUSION: It can be concluded that the Brazilian Portuguese version of the Smartphone Addiction Scale-Short Version is a reliable and valid tool for screening smartphone addiction in university students.

BACKGROUND: The Fonseca Anamnestic Index is a questionnaire used to classify individuals with temporomandibular disorders. Previous studies have shown that the Fonseca Anamnestic Index provides a multidimensional measurement of the temporomandibular disorders construct and that the main dimension presents a good fit to the model according to the item response theory. OBJECTIVE: To evaluate the between-day reliability, accuracy, and best cut-off score of the Short-Form Fonseca Anamnestic Index for the diagnosis of myogenous temporomandibular disorders. METHODS: The sample consisted of 123 women (57 with myogenous temporomandibular disorders and 66 asymptomatic), evaluated by the Research Diagnostic Criteria for Temporomandibular Disorders. The participants answered the Short-Form Fonseca Anamnestic Index on two occasions with a seven-day interval between tests. For the analysis of between-day reliability, the intraclass correlation coefficient, the standard error of measurement and the minimum detectable change were used. The Receiver Operating Characteristic curve was used to determine the diagnostic accuracy and the best cut-off point. RESULTS: The Short-Form Fonseca Anamnestic Index demonstrated excellent reliability (intraclass correlation coefficient≥0.95) for all items and for the total Short-Form Fonseca Anamnestic Index score (intraclass correlation coefficient=0.98; standard error of measurement=3.28; minimum detectable change=9.09). The level of accuracy of the Short-Form Fonseca Anamnestic Index for the diagnosis of myogenous temporomandibular disorders was high (area under the curve of 0.97), with a better cut-off score of 17.5 points. CONCLUSION: The Fonseca Anamnestic Index should be used in its short form to classify the absence of myogenous temporomandibular disorders (scores between 0 and 15 points) or presence of myogenous temporomandibular disorders (scores between 20 and 50 points) in women.

Introduction: Workers of the metallurgical industry are constantly exposed to occupational risk factors that can lead to the development of work-related musculoskeletal disorders (WMSDs). These disorders are highly debilitating, generating losses to workers, companies and the State. Objective: To identify and verify the connection between risk factors and WMSDs in metallurgical workers in the manufacture of machinery and equipment. Method: This is a cross-sectional epidemiological study that involves registered workers of the Occupational Health Reference Service (Cerest) in São Paulo state. The survey was conducted through review of electronic medical records. Results: 2116 electronic medical records were analyzed, from these, 36 were considered for the sample. We observed that 91.6% (n = 33) of the participants were men, age range from 29 to 62 years and the most prevalent occupational status was unemployment (47.3% (n = 17)). The WMSDs were found in the upper limbs and spine region, predominantly spine. Repetitiveness was the most prevailing risk factor (94.4% (n = 34)). A connection between repetitiveness (p = 0.0046) and physical exertion (p = 0.001) with symptoms in the spine was detected. Conclusion: The spine is the main body region affected in these workers. There was a link between repetitiveness and physical exertion with the symptoms of spine pain. The results strengthen the need for interventions in the workplace to minimize repetitive work and excessive physical exertion seeking prevention and workers' health promotion.

Os Dort foram encontrados em membros superiores e região de coluna. A repetitividade foi o fator de risco mais prevalente (94,4% (n = 34)). Foi encontrada associação entre repetitividade (p = 0,0046) e esforço físico (p = 0,001) com sintomas na coluna vertebral. Conclusão: Conclui-se que a coluna vertebral é a principal região corporal acometida nesses trabalhadores. Houve uma associação entre repetitividade e esforço físico com os sintomas de dor na região da coluna. Isso reforça a necessidade de intervenções no ambiente de trabalho, visando minimizar o trabalho repetitivo e o esforço físico excessivo, buscando a prevenção e promoção na saúde do trabalhador.
RESUMEN
Physical effort stimulates an increase in oxygen consumption in tissues, generating toxic chemical species derived from oxygen (ROS), which are considered the initiators of the lipid peroxidation process (LPO), the major mechanism of cellular injury. As the essential mechanism for maintaining the electrolyte balance depends on an effective kidney function, oxidative stress in this organ can be a key factor in the development and persistence of hypertension. This study aimed to determine the kidney changes induced by a combination of fluid restriction and exercise in rats. The study consisted of 24 male Wistar rats of 90 days of age, divided into four groups, two of which were submitted to water restriction and exercise on a treadmill.Twenty-four hours after the last training session, the animals were euthanized and the left kidney was removed.The upper part of the kidney was used for the histological procedures and the lower part for the quantification of membrane lipoperoxides.Analysis of variance was applied after testing the normality of data, and the comparison between groups was performed using the Bonferroni test, adopting a significance of p<0.05. The restriction had an influence on body weight; kidney weight; proximal tubule maximum diameter; and area, perimeter and diameter of glomeruli, whereas the exercise affected the weight and the minimum diameter of the proximal tubule. According to the TBARS (thiobarbituric acid reactive substances) method, there was a difference between the G1 (control) and G3 (sedentary with water restriction) and between the G2 (exercised with water) and G4 (exercised with water restriction) compared to G1. The treadmill exercise combined with the water restriction promoted structural changes in the glomeruli and promoted oxidative stress, although neither variable corroborated for the potentiating of lipid peroxidation.
El esfuerzo físico estimula un aumento en el consumo de oxígeno en los tejidos, generando variedades químicas tóxicas derivadas de oxígeno (ROS), que son considerados iniciadores del proceso de peroxidación lipídica (LPO), principal mecanismo de lesión celular. Como el mecanismo esencial para mantener el equilibrio de los electrolitos depende de una función renal eficaz, el estrés oxidativo en este órgano puede ser un factor clave en el desarrollo y persistencia de la hipertensión. Este estudio tuvo como objetivo determinar los cambios renales en ratas, inducidos por una combinación de restricción de líquidos y ejercicio. Esta investigación se realizó en 24 ratas Wistar machos de 90 días de edad, divididos en cuatro grupos, dos de los cuales fueron sometidos a restricción de agua, mientras que los dos grupos restantes fueron ejercitados en una caminadora. Veinticuatro horas después de la última sesión de entrenamiento, los animales fueron sacrificados y se realizó la extracción del riñón izquierdo. La parte superior del riñón se usó para los procedimientos histológicos y la parte inferior para la cuantificación de peróxidos lipídicos en la membrana. El análisis de varianza se aplicó después de probar la normalidad de los datos, y la comparación entre grupos se realizó mediante la prueba de Bonferroni, adoptando una significación de p<0,05. La restricción hídrica tuvo influencia sobre: el peso corporal, peso de los riñones, diámetro máximo del túbulo proximal, y área, perímetro y diámetro de los glomérulos. Mientras que el ejercicio afectó el peso y el diámetro mínimo del túbulo proximal de las ratas. Según el método SRAT (sustancias reactivas al ácido tiobarbitúrico), existió una diferencia entre el G1 (control) y G3 (sedentarismo con restricción de agua) y entre el G2 (ejercicio con agua) y G4 (ejercicio con restricción de agua) en comparación con G1. El ejercicio rodante combinado con la restricción de agua promovió cambios estructurales en los glomérulos y estimuló el desarrollo de estrés oxidativo, aunque ninguna variable fue corroborada para establecer la potenciación de la peroxidación lipídica.
