Effects of respiratory exercises in sleep bruxism and associated obstructive sleep apnea: a double-blind, placebo-controlled randomized clinical trial.

PURPOSE: The aim of this study is to assess the effects of respiratory exercises (inspiratory and expiratory) in individuals with sleep bruxism (SB) and associated obstructive sleep apnea (OSA). METHODS: This is a double-blind, placebo-controlled randomized clinical trial including individuals with SB and associated respiratory events in OSA. Respiratory physical therapy was performed using inspiratory (Threshold® IMT), expiratory (Threshold® PEP) muscle training, and compared with a placebo group. A total of 30 daily respiratory cycles (inspiration and expiration) were performed five times a week for 12 weeks. Individuals were reassessed at two times, at baseline (T1) and after 12 weeks of training (T2) by means of the Pittsburgh Sleep Quality Index and Polysomnography. RESULTS: Awakening was significantly different (p ≤ 0.05) between the inspiratory group and placebo 12 weeks after respiratory physical therapy. The number of contractions of the masseter muscle differed between the inspiratory, expiratory, and placebo groups (p ≤ 0.05). CONCLUSION: Respiratory physical therapy for OSA improved awaking levels in 80 and 67% of the number of masseter muscle contractions, when compared to placebo. TRIAL REGISTRATION: Brazilian Registry of Clinical Trials (No. RBR-9F6JKM).

Relationship Between Chloroquine or Hydroxychloroquine Use and Hearing Disorders: A Systematic Review and Meta-Analysis.

BACKGROUND AND OBJECTIVES: Chloroquine and its analog hydroxychloroquine are derivatives of 4-aminoquinoline and are regularly used in the treatment of malaria and autoimmune diseases. Among the side effects of these drugs, alterations associated with the auditory system are frequently mentioned. Thus, the aim of this systematic review is to systematically review publications on hearing disorders and chloroquine or hydroxychloroquine use. MATERIALS AND METHODS: Inclusion criteria were observational or interventional studies on audiological assessment in participants who were using chloroquine or hydroxychloroquine. The methodological quality was independently assessed by two reviewers using the Meta-Analysis of Statistics: assessment and review Instrument. The certainty of the evidence was assessed using the GRADE tool. RESULTS: A total of 1,372 non-duplicate papers were screened, out of which 17 were included in the final qualitative synthesis, and 5 studies in the meta-analysis. The odds ratio for the two subgroups evaluated did not show significance with no heterogeneity between the effects observed between the different diseases (I2=0%) and obtaining the global estimate of 0.76 (95% confidence interval [CI]=0.41-1.39; p>0.05). Despite the inclusion of papers with different disease samples, the heterogeneity observed in the analysis was low (I2= 0%) and prediction interval (95% PI=0.32-1.80; p>0.05) remained close to that estimated by the CI (95% CI=0.41-1.39; p>0.05). The certainty of the evidence assessed by the GRADE tool was considered very low due to the risk of bias, indirect evidence, and imprecision. CONCLUSIONS: The findings of this study suggest that the use of chloroquine/hydroxychloroquine is not associated with hearing disorders.

The Prevalence of Oropharyngeal Dysphagia in Adults: A Systematic Review and Meta-analysis.

To determine the global prevalence of oropharyngeal dysphagia (OD) in adults. Six electronic databases (Embase, LILACS, LIVIVO, PubMed/Medline, Scopus, and Web of Science) were searched, in addition to gray literature (ASHA, Google Scholar, ProQuest Dissertation, and Theses). A random-effects model for meta-analysis of proportions was conducted, and heterogeneity was evaluated according to the moderator variable through subgroup analysis and meta-regression. The risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist and the certainty of the evidence was assessed using the GRADE tool. Thirty papers were included for qualitative and quantitative synthesis. The combined prevalence estimate was 60% [CI 95% = 50%-70%; I2 = 95%], accounting for different baseline conditions. However, the wide variation that exists between the different baseline conditions (underlying disease or risk factor) tended to overestimate this prevalence when considering the general population. Only one study evaluated healthy individuals, which showed a prevalence of 31% [CI95% = 27%-36%]. The risk of bias was considered low for all studies. None of the variables were considered predictors for the observed variance between the effect sizes of the included studies. For the prevalence of OD, the GRADE rating was considered very low. Despite the high prevalence observed, with over half of the individuals affected, the evidence regarding this outcome remains uncertain due to an overestimation of the generated estimates caused by the baseline condition of the sample.

Impact of dentofacial deformity on the chance of being hired for a job.

Objective: This study aimed to determine the impact of dentofacial deformity on an individual's chances of being hired for a hypothetical job involving customer service. Materials and methods: Face photographs (frontal and lateral) of 15 patients with moderate to severe dentofacial deformity, taken before and after orthodontic-surgical correction, were selected and randomized between two different questionnaires. In addition, five patients without dentofacial deformity were used as controls in both questionnaires. These questionnaires were taken by adults responsible for hiring personnel to work in commerce and business activities, graduates or postgraduates in business administration, with experience in recruiting and hiring personnel. The evaluation took place using a Likert scale with values ranging from 0 to 10 (in which 0 corresponded to complete disagreement and 10 to complete agreement), considering the following variables in a first impression judgment: honesty, intelligence, productivity at work, and hiring chance. Data were tabulated and statistical analysis was performed using a linear regression model for the explanatory variables that showed statistical significance in the analysis of variance (ANOVA). Effect size through Cohen's d has been corrected for all comparisons performed. Results: All re-examined domains demonstrated statistical differences even when included in a multivariate model (p < 0.05), with lower mean values for those requiring pre-treatment (presenting deformity), although the effect size was small for all comparisons. Conclusion: Dentofacial deformity influenced the hiring chance, although not appearing to be a preponderant factor for hiring, acting as a tiebreaker among the candidates adopted.

Clinical and Acoustic Alterations of Swallowing in Children Exposed to Zika Virus during Pregnancy in a Cohort in Amazonas, Brazil: A Case Series Study.

Oropharyngeal dysphagia (OD) is a swallowing disorder that involves difficulty in safely passing the food bolus from the oral cavity to the stomach. OD is a common problem in children with congenital Zika virus syndrome (CZS). In this case series, we describe the clinical and acoustic alterations of swallowing in children exposed to the Zika virus during pregnancy in a cohort from Amazonas, Brazil. From July 2019 to January 2020, 22 children were evaluated, 6 with microcephaly and 16 without microcephaly. The mean age among the participants was 35 months (±4.6 months). All children with microcephaly had alterations in oral motricity, mainly in the lips and cheeks. Other alterations were in vocal quality, hard palate, and soft palate. Half of the children with microcephaly showed changes in cervical auscultation during breast milk swallowing. In children without microcephaly, the most frequently observed alteration was in lip motricity, but alterations in auscultation during the swallowing of breast milk were not observed. Regarding swallowing food of a liquid and pasty consistency, the most frequent alterations were incomplete verbal closure, increased oral transit time, inadequacy in capturing the spoon, anterior labial leakage, and increased oral transit time. Although these events are more frequent in microcephalic children, they can also be seen in non-microcephalic children, which points to the need for an indistinct evaluation of children exposed in utero to ZIKV.

Internal Consistency of the Voice Handicap Index in Individuals With Dysphonia: A Systematic Review and Meta-Analysis.

OBJECTIVE: To analyze the internal consistency of the Voice Handicap Index (VHI) for evaluating the vocal handicap of individuals with dysphonia. METHODS: This is a systematic review. Studies with a cross-sectional design and including a population of individuals with dysphonia, which validated the VHI and analyzed its internal consistency, were included. The following electronic databases were searched: Cochrane Library, EMBASE, LILACS, and PubMed, including Medline, Scopus, and Web of Science. A manual search was performed in gray literature through the Biblioteca Digital Brasileira de Teses e Dissertações and ProQuest Dissertation & Theses. In addition, the list of references of studies selected in the electronic search was mapped, and an expert in the area was consulted. Two reviewers blindly and independently conducted the selection, data extraction, and analysis of the risk of bias, the certainty of the evidence, and good psychometric measures. A meta-analysis was performed with a random effects model using the JAMOVI 2.3.2 software. RESULTS: Forty-nine studies were analyzed. In risk of bias assessment, the studies were classified as having inadequate structural validity and very good internal consistency. The analysis of good psychometric properties indicated indeterminate structural validity and insufficient internal consistency. The overall value of Cronbach's alpha was estimated at 0.94, thus suggesting a very good internal consistency. However, there was high heterogeneity. The level of certainty of the evidence was too low for internal consistency. CONCLUSION: The VHI proved to be a consistent and reliable patient-reported outcome measure to evaluate voice handicap in individuals with dysphonia; however, studies are heterogeneous, and the certainty of evidence is very low.

The therapeutic link in the speech therapy clinic: a necessary reflection. / O vínculo terapêutico na clínica fonoaudiológica: uma reflexão necessária.

PURPOSE: To understand the meanings that the therapeutic bond assumes for clinical speech therapists. METHODS: The research was approved by the Ethics Committee, being of a transversal character, with a quantitative-qualitative approach in the Content Analysis. The research with the participation of 96 clinical speech therapists, registered in the Speech Therapy Council of the 3rd region (CRFa 3), which covers the States of Paraná and Santa Catarina. RESULTS: Of the 96 speech therapists included, a significant part of the participants defined the therapeutic bond as a relationship/interaction. Regarding the role of the bond for the speech therapy clinical work, most professionals declared theirs as a fundamental basis and another part of the bond is necessary for the evolution/development of the patient. CONCLUSION: It is possible to understand that, according to the therapeutic patients, it is essential to sustain, maintain the clinical work for users, impacting the resignification of the complaint and the minimization of the users' suffering.

Referente ao papel do vínculo para o trabalho clínico fonoaudiológico, a maioria dos profissionais o descreveu como base fundamental e outra parte deles afirmou que tal vínculo é necessário para a evolução/desenvolvimento do paciente. CONCLUSÃO: É possível compreender que, de acordo com os participantes, a relação terapêutica é essencial para a sustentação e manutenção do trabalho clínico fonoaudiológico, impactando na ressignificação da queixa e na minimização do sofrimento dos usuários.

Diagnosis of TMJ degenerative diseases by panoramic radiography: is it possible? A systematic review and meta-analysis.

OBJECTIVE: The objective of this work was to determine the diagnostic accuracy of panoramic radiography in detecting degenerative diseases of the temporomandibular joint. METHOD: The protocol was registered at the PROSPERO website. To consider the eligibility of studies to be included/excluded from this review, the acronym "PIRDS" was used and appropriate word combinations and truncations were adapted in the following electronic databases: PubMed/Medline, EMBASE, Latin American and Caribbean Literature on Health Sciences, Web of Science, Scopus, and Cochrane Library. RESULTS: A total of 2572 references, after the removal of duplicates, were retrieved from the eight electronic databases. After reading the titles and abstracts, a total of 26 articles were selected for full reading, of which ten were excluded, resulting in 16 articles included for qualitative synthesis. All in vivo studies were classified as having a low risk of bias. Regarding in vitro studies none of the included studies scored below 80% in the overall evaluation. CONCLUSIONS: Both in vitro and in vivo studies consistently report a low accuracy in detecting degenerative diseases of the temporomandibular joint using panoramic radiography. CLINICAL RELEVANCE: Cone-beam computed tomography offers a superior image quality without overlapping structures and a higher accuracy compared to panoramic radiography. However, panoramic radiography can still serve as an initial examination when combined with a clinical assessment. CBCT should be reserved for cases where there are evident clinical and/or radiographic alterations that recommend its use. This approach ensures a judicious and cost-effective use of CBCT resources.

Impact of orthognathic surgery on voice and speech: a systematic review and meta-analysis.

BACKGROUND: Orthognathic surgical procedures, whether in one or both jaws, can affect structures regarding the articulation and resonance of voice and speech. OBJECTIVE: Evaluating the impact of orthognathic surgery on voice and speech performance in individuals with skeletal dentofacial disharmony. SEARCH METHODS: Word combinations and truncations were adapted for the following electronic databases: EMBASE, PubMed/Medline, Scopus, Web of Science, Cochrane Library, and Latin American and Caribbean Literature in Health Sciences (LILACS), and grey literature. SELECTION CRITERIA: The research included studies on nonsyndromic adults with skeletal dentofacial disharmony undergoing orthognathic surgery. These studies assessed patients before and after surgery or compared them with individuals with good facial harmony using voice and speech parameters through validated protocols. DATA COLLECTION AND ANALYSIS: Two independent reviewers performed all stages of the review. The Joanna Briggs Institute tool was used to assess risk of bias in the cohort studies, and ROBINS-I was used for nonrandomized clinical trials. The authors also performed a meta-analysis of random effects. RESULTS: A total of 1163 articles were retrieved after the last search, of which 23 were read in full. Of these, four were excluded, totalling 19 articles for quantitative synthesis. When comparing the pre- and postoperative periods, both for fundamental frequency, formants, and jitter and shimmer perturbation measures, orthognathic surgery did not affect vowel production. According to the articles, the main articulatory errors associated with skeletal dentofacial disharmonies prior to surgery were distortions of fricative sounds, mainly/s/ and/z/. CONCLUSIONS: Orthognathic surgery may have little or no impact on vocal characteristics during vowel production. However, due to the confounding factors involved, estimates are inconclusive. The most prevalent articulatory disorders in the preoperative period were distortion of the fricative phonemes/s/ and/z/. However, further studies must be carried out to ensure greater robustness to these findings. REGISTRATION: PROSPERO (CRD42022291113).

Prevalence of signs and symptoms related to temporomandibular disorders and orofacial pain in patients indicated for orthognathic surgery: a meta-analysis.

OBJECTIVE: To evaluate the prevalence of signs and symptoms related to temporomandibular disorders (TMD) and orofacial pain in patients with indication for orthognathic surgery. METHODS: The search was carried out in seven electronic databases and gray literature. Studies that evaluated the frequency of signs and symptoms related to TMD and orofacial pain were included. The risk of bias was assessed using the Joanna Briggs Critical Appraisal tool. A meta-analysis of proportions with a random effect model was performed and the GRADE tool judged the certainty of evidence. RESULTS: After searching the databases, 1859 references were retrieved, 18 of which were selected for synthesis. The prevalence of individuals with at least one TMD symptom was 51% [CI95% = 44-58%], and 44% of the subjects had temporomandibular joint click/crepitus [CI95% = 37-52%]. Additionally, 28% exhibited symptoms related to muscle disorders [CI95% = 22-35%], 34% had disc displacement with or without reduction [CI95% = 25-44%], and 24% had inflammatory joint disorders [CI95% = 13-36%]. The prevalence of headache was 26% [CI95% = 8-51%]. The certainty of evidence was considered very low. CONCLUSION: Approximately 1 in 2 patients with dentofacial deformity presents some sign and symptom related to TMD. Myofascial pain and headache may be present in approximately a quarter of patients with dentofacial deformity. CLINICAL RELEVANCE: A multidisciplinary treatment is necessary for these patients, involving a professional with expertise in the management of TMD.

The Self-Stigma of Hearing Loss in Adults and Older Adults: A Systematic Review.

OBJECTIVES: Previous studies have demonstrated that individuals with hearing loss can internalize social stigmas, resulting in several self-perceived negative connotations, such as incompetence, cognitive impairment, and social disability. This systematic review aimed to investigate the impact of the social stigma associated with hearing loss on the self-stigma experienced by adults and older adults. DESIGN: Combinations of words and appropriate truncations were selected and adjusted specifically for each electronic database. The Population, Exposure, Comparator, Outcomes, and Study Characteristics strategy was used to delimit the scope of the review, bearing in mind the importance of a well-formulated research question. RESULTS: A total of 953 articles were retrieved from the final search of each database. Thirty-four studies were selected for full-text reading. Thirteen were excluded, and 21 studies were ultimately included in this review. The results of this review were divided into three themes: (1) impact of social stigmas on self-stigma, (2) effect of emotions on self-stigma, and (3) other factors that impact self-stigma. The themes were related to the relationship between the individual and social perceptions reported by the participants with respect to their hearing experiences. CONCLUSIONS: Our results suggest that the impact of social stigma associated with hearing loss on the self-stigma of adults and older adults is strongly associated with the effects of aging and hearing loss, which may lead to withdrawal, social segregation, and negative self-perception.

Evidence on Vocal Interventions in Adults: A Scoping Review.

OBJECTIVE: To map the evidence on vocal intervention in people over 18 years old. METHODS: A literature search was conducted using the following electronic databases: Cochrane Library, EMBASE, Latin American and Caribbean Literature on Health Sciences (LILACS), LIVIVO, Pubmed/Medline, Scopus, SpeechBITE, and Web of Science. Gray literature was also used as an information source through searches on Google Scholar, Open Grey, ProQuest Dissertation and Thesis, and the Brazilian digital library of theses and dissertations. Systematic reviews (SR) with a population of individuals over 18 years old were included. The included reviews addressed speech-language pathology interventions in the vocal area with reports of their respective outcome. The methodological quality of the included systematic reviews was analyzed using the AMSTAR II tool. Quantitative analysis was performed by frequency distribution, and qualitative research was analyzed through narrative synthesis. RESULTS: A total of 2,443 references were retrieved, among which 20 studies met the inclusion criteria. The included studies had critically low quality, lacking the use of population, intervention, comparison, and outcome (PICO) components. Among the included SRs, 40% were made in Brazil, 45% were published in the Journal of Voice, and 75% analyzed dysphonic patients. The most frequent intervention was voice therapy (direct therapy associated with indirect therapy approaches). Positive results were observed in most of the outcomes for all studies. CONCLUSION: Voice therapy was described as inducing positive effects for voice rehabilitation. However, due to the critically low quality of studies, the literature did not enable us to understand the best results for each intervention. Well-designed studies are necessary to clarify the relationship between the intervention goal and how the intervention was evaluated.

Association between atypical swallowing and malocclusions: a systematic review.

OBJECTIVE: This systematic review aims to answer the following focus question: "Is there an association between atypical swallowing and malocclusions?". METHODS: Appropriate word combinations were chosen and tailored specifically for each of the following electronic databases: EMBASE, Latin American and Caribbean Literature in Health Sciences (LILACS), LIVIVO, PubMed/Medline, Scopus, Web of Science, and gray literature, without any restrictions, up to February 2021. According to the selection criteria, only cross-sectional studies were included. The following inclusion criteria were considered: a sample composed of children, adolescents, and adults; patients clinically diagnosed with atypical swallowing; patients with normal swallowing; and outcome of interest of atypical swallowing in patients with malocclusion. The data consisted of study characteristics, sample characteristics, results, and conclusion of each study. The risk of bias was assessed using the JBI Critical Appraisal Checklist for Analytical Cross-Sectional Studies, and the certainty of evidence was assessed using the GRADE tool. RESULTS: 4,750 articles were identified. After a two-step selection, four studies were included. A higher frequency of distal occlusion, extreme maxillary overhang, and open bite was related to swallowing disorders; most studies pointed to posterior crossbite as a malocclusion more associated with atypical swallowing. All studies had a moderate to high risk of bias, and the certainty of evidence was very low. CONCLUSION: The results indicate that atypical swallowing is associated with malocclusions and that posterior crossbite is the main malocclusion found, but only in the young population (3-11 years). REGISTRATION: PROSPERO (42020215203).

Impact of bariatric surgery on oral health: a systematic review and meta-analysis.

OBJECTIVE: To evaluate the impact of bariatric surgery (BS) on the oral health status of obese individuals. MATERIAL AND METHODS: The search was performed on the Cochrane Library, Embase, Latin American and Caribbean Literature on Health Sciences (LILACS), LIVIVO, PubMed/Medline, Scopus, and Web of Science databases. Grey literature was also consulted through Google Scholar, OpenGrey, ProQuest, and MedRxiv. The risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal tool. Pre- and post-surgical moments were compared through random effects meta-analysis. The GRADE (Grading of Recommendations, Assessment, Development and Evaluations) assessment tool was used to judge the certainty of evidence. RESULTS: After searching the databases, 908 references were retrieved, with 30 articles selected for synthesis. When comparing the pre- and postoperative moments, there was no difference in the index of decayed, missing, or filled teeth. Furthermore, salivary flow and probing depth presented a slight increase. Post-surgery patients showed an increase (%) in tooth wear at the dentin level [MD = -6.23; IC95% = -8.45--4.01; I2 = 0%]. CONCLUSION: Patients undergoing BS show no difference when considering the rate of caries or missing teeth and little to no effect was observed on salivary flow rates and periodontal probing depth. On the other hand, greater attention should be given to dentin wear in post-surgical patients of BS. CLINICAL RELEVANCE: Patients undergoing BS should receive careful monitoring regarding oral health by doctors, dentists, and the entire multidisciplinary team involved before and after the surgical procedure.

Worldwide prevalence and associated risk factors of obstructive sleep apnea: a meta-analysis and meta-regression.

PURPOSE: This study aimed to identify the prevalence of obstructive sleep apnea (OSA) and associated risk factors globally. METHODS: Six databases and registrations and three grey databases were explored for observational field research. Independently and impartially paired reviewers selected research, gathered data, and evaluated the methodological quality. Heterogeneity was investigated using subgroup analysis and meta-regression following the moderating variable in a meta-analysis of proportions with a random-effects model. The critical appraisal instrument developed by the Joanna Briggs Institute was used to evaluate the listed studies' methodology. The certainty of the evidence was evaluated using the GRADE tool. RESULTS: A total of 8236 articles were collected during the database search, resulting in 99 articles included for qualitative synthesis, and 98 articles were included for the meta-analysis. The estimated combined prevalence of OSA was 54% [CI 95% = 46-62%; I2 = 100%]. Mean age, percentage of moderate-severe cases, and the sample's body mass index (BMI) did not affect the heterogeneity that was already present when meta-regressed (p > 0.05). Ninety-one studies were deemed to have a low risk of bias, while eight were deemed to have a moderate risk. For OSA prevalence outcomes, the GRADE criteria were considered very low. CONCLUSION: Approximately half of the people worldwide have OSA. High BMI, increasing age, and male gender are described as risk factors in the literature, but these covariates do not affect pre-existing heterogeneity.

Periodontal parameters in orthodontically tractioned teeth: A systematic review and meta-analysis.

Objective: This systematic review aimed to evaluate periodontal parameters in orthodontically tractioned teeth compared with the respective non-tractioned contralateral teeth. Methods: Search strategies were developed for six electronic databases and gray literature. Random-effects meta-analyses were performed for the outcomes of interest. Furthermore, the certainty of the evidence was assessed using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) tool. Results: Overall, 2,082 articles were identified, of which 24 were selected for the qualitative synthesis. A significant difference was observed between the impacted and contralateral teeth (mean difference [MD] = 0.25; 95% confidence interval [CI] = 0.10-0.40; I2 = 0%) when the gingival index was evaluated. Additionally, impacted teeth showed a greater probing depth, with a significant mean difference between the groups (MD = 0.14; 95% CI = 0.07-0.20; I2 = 6%). Most studies had a low risk of bias; however, the certainty of the evidence was very low owing to the design of existing studies. Conclusions: The evidence in the literature indicated that tractioned teeth might show worsening of periodontal parameters related to the gingival index and probing depth; however, the evidence remains uncertain about this outcome. Furthermore, probing depth should be considered regarding its clinical significance because of the small effect size observed.

Presentation and Evaluation of the Teacher's Vocal Health Guide.

OBJECTIVE: in order to contribute of the collective actions of the teacher's vocal health, the specific goal was to build a guide gathering the appliable didactic content in these actions. That being, the stages performed in the instrument elaboration of the denominated Teachers' Vocal Health Guide (TVHG) will be presented. MATERIAL AND METHODS: The elaboration process of the guide is composed of three stages: (1) parameter selection to compose the guide based on a literature review; (2) submission to a specialist examining board, with the calculation of the Content Validity Index (CVI) and the Kappa agreement coefficient; (3) content validation - the instrument was submitted to an analysis of a judges committee, and from the results the Cronbach Alfa coefficient and the CVI were calculated. RESULTS: The elaboration of the TVHG underwent three stages. In the first stage, called parameter selection, 20 didactic contents were found, consisting of 14 theoretical and six practices. In the second stage, an evaluation of the guide was performed by a specialist examining board and two contents were excluded since their CVI was below 8. The result of the Kappa Coefficient Calculation was 0.281. In the third stage, the TVHG underwent evaluation of a new group denominated judges committee, and the items were punctuated as very relevant and completely relevant. The result of the Cronbach Alfa coefficient for the instrument with 18 items was 0.721, and this value categorizes the instrument as valid. It is necessary to continue the process of instrument validation, possibly investigating the applicability of TVHG in the teachers' opinion. CONCLUSION: The current study presents the TVHG from the description of the three stages performed to elaborate a systematized instrument denominated TVHG, which suggests a gathering of didactic content that are appliable in collective actions of vocal health with this professional category.
