RESUMO

Objective: To investigate the action of osteopathic manipulative treatment on the muscular activity of the stomatognathic apparatus by using surface electromyography (sEMG). Material and Methods: Surface electromyography (sEMG) was performed on the masseter and anterior temporalis muscles of 120 subjects (73 F; 47 M), both at time T0 and T2. The sample was divided into three randomized groups of 40 subjects each: control, placebo, and osteopathic manipulative treatment (OMT). In the T1 interval between the two evaluations, the control group was not treated, the placebo group underwent a placebo treatment, and the OMT group underwent manipulative treatment. The mean value of each measurement and its coefficient of variation, between time T0 and T2, were calculated for both the intragroup (OMT, placebo, control) and the intergroup (OMT-placebo, OMT-control). Outcomes: In 40% of the subjects, statistically significant improvements were highlighted in the OMT. Whereas, the statistically significant results of the placebo and control groups were 7.5% and 17.5%, respectively, of which more than 75% moved away from the physiological range, showing a worsening of the muscular activity. This analysis showed statistically significant variations (p ≤ 0.05) in the OMT group compared to the placebo and the control groups. Conclusions: OMT determines variations of the activity of masticatory muscles.

RESUMO

Recent studies showed an evident correlation between the stomatognathic system and the visual system. These results suggest that subjects who are affected by both temporomandibular (TMD) disorders and refractive disorders present with altered control of pericranial musculature tone and higher open-eye electromyographic (EMG) values. The objective of this work was to evaluate the effects of standard vision correction on EMG in subjects suffering from TMD compared with application of the same vision treatments to non-TMD subjects. 40 subjects were enrolled in this study. The test group included 20 myopic subjects and also included patients with TMD. The control group included 20 healthy myopic subjects. All of the participants underwent a complete ocular examination and a sEMG analysis. The results showed that TMD subjects with vision disorders that are corrected with standard glasses present EMG values that are significantly higher than those presented by non-TMD subjects with vision disorders and standard glasses. Infact, in TMD subjects, eye correction did not have a positive effect on the stomatognathic or pericranial musculature.

RESUMO

Manual tests in clinical investigation must be supported by anatomical and physiological findings in order to obtain an objective information. The application of different mandibular positions in children obtains a variation in the 'hip rotators test' (p < 0.001). The possible relationships behind the muscle tone of the external rotators of the hips and the stomatognathic system are exposed, with special attention on the fascial tissue and its morphological characteristics. Despite these anatomical and physiological connections, there is no further evidence of a strong cause-effect relationship in this test.


Las pruebas manuales en la investigación clínica deben estar respaldadas por hallazgos anatómicos y fisiológicos para obtener una información objetiva. La aplicación de diferentes posiciones mandibulares en niños muestra una variación en la "prueba de rotadores de cadera" (p <0,001). Se exponen las posibles relaciones del tono muscular de los rotadores externos de las caderas y el sistema estomatognático, con especial atención en el tejido fascial y sus características morfológicas. A pesar de estas conexiones anatomofisiológicas, no existe una evidencia mayor de una relación importante causa-efecto en esta prueba.

RESUMO

OBJECTIVE: To characterize the eating behavior, orofacial, speech myofunctional conditions, and facial temperature of children with congenital heart disease. METHOD: This is a cross-sectional and analytical study. The sample consisted of 30 children with heart disease (cyanotic or acyanotic; mean of 5.48 ± 0.84 years old) and 28 healthy children (4.98 ± 0.64 years old). Parents were given a questionnaire to assess eating behaviors (Montreal Children's Hospital Feeding Scale). The orofacial myofunctional assessment protocol (OMES-E), the Child Language Test (ABFW), and thermography infrared of facial temperature were used. Data analysis was conducted by student's t-tests, Chi-square, logistic regression, and correlation analysis. RESULTS: Eating behavior in Parents did not perceive eating behavior differences between the heart disease and control groups. However, the percentage of children with some feeding difficulty was higher in the heart disease group. There was a difference between groups regarding the appearance and posture of structures, the mobility of the mandibular and cheek, swallowing function, and the total function score. Thermographic variables did not differ between the groups, but better performance in orofacial functions correlated with the temperature of the labial commissure and lower lip points. CONCLUSIONS: The frequency of children with eating difficulties was higher among those with congenital heart disease, as was the increased facial temperature at the medial eyelid commission point when submitted to interventional procedures. The orofacial myofunctional aspects showed changes in posture and position, mobility, and orofacial functions among children with heart disease as compared to the control group. There was a correlation between the temperature of the thermo-anatomical points of the labial commissure and the lower lip as well as the OMES-E function score. (AU)

RESUMO

The radular morphology of the patellid species Testudinalia testudinalis (O. F. Müller, 1776) from the White Sea was studied using light, electron, and confocal microscopy. The radula is of the docoglossan type with four teeth per row and consisting of six zones. We characterize teeth formation in T. testidinalis as follows: one tooth is formed by numerous and extremely narrow odontoblasts through apocrine secretion; this initially formed tooth consists of numerous vesicles; the synthetic apparatus of the odontoblasts is localized in the apical and central parts of the cells throughout the cytoplasm and is penetrated by microtubules which are involved in the transport of the synthesized products to the apical part of the odontoblast; the newly formed teeth consist of unpolymerized chitin. Mitotic activity is located in the lateral parts of the formation zone. The first four rows contain an irregular arrangement of teeth, but the radular teeth are regularly arranged after the fifth row. The irregularly arranged teeth early on could be a consequence of the asynchronous formation of teeth and the distance between the odontoblasts and the membranoblasts. The morphological data obtained significantly expands our knowledge of the morphological diversity of the radula formation in Gastropoda.

RESUMO

Abstract Introduction Chewing and swallowing are physiologically interconnected functions, which share motor structures and supranuclear regions of the central nervous system (CNS), involving a sensorimotor synchrony. Objective To analyze the influence of masticatory behavior on muscular compensations in the oral phase of swallowing in smokers compared with nonsmokers. Methods A cross-sectional study comparing smokers and nonsmokers composed of 24 participants in each group. The aspects of food crunching, masticatory pattern, masticatory speed, atypical muscular contractions, and lip closure were analyzed during mastication. In swallowing, aspects of contraction of the orbicular and mental muscles, head movement and presence of deglutition, mastication, smoking, and of stomatognathic system of residues after swallowing were characterized. Results Statistically significant differences were identified between the study groups related to food grinding pattern, masticatory velocity, and mental contraction during swallowing. There was no significant association between masticatory function and compensations during swallowing. Conclusion Differences were observed in the pattern of chewing and swallowing in smokers compared with nonsmokers, but no influence of masticatory performance was observed in the presence of muscle compensations during the oral phase of swallowing.

RESUMO

Abstract Objectives: To investigate full term newborns suction pattern in non-nutritive suction and their feeding performance. Methods: An analytical descriptive study was carried out from November 2016 to March 2017, with 50 dyads mothers/newborns through the non-nutritive suction evaluation and a direct observation on the newborn's performance on feeding. The data were distributed through simple and relative frequencies (percentages) when categorical or by mean, maximum, minimum and the standard deviation when is continuous, discrete or ordinal. To evaluate the mean differences, the Student's t test was used with significance level of 5%. Results: There were significant differences among the newborn's mandible movement ("newborn's mouth slightly open" p=0,005), suction ("cheek strain during feeding" p<0,001) and dyad mother and newborn positioning ("breasts supported with fingers on the areola" p=0,041 and baby's neck or trunk turned" p=0,041). Conclusions: Newborns that presented changes in their mandible movement on the Non-Nutritive Suction (NNS) also presented difficulties in feeding. The newborn's knowledge on suction pattern through the NNS has proven to be an important strategy that may help identify possible difficulties during feeding.


Resumo Objetivos: investigar o padrão de sucção de recém-nascidos a termo na sucção não-nutritiva e sua relação com o desempenho destes na mamada. Métodos: estudo descritivo analítico, realizado de novembro de 2016 a março de 2017, com 50 díades mãe/recém-nascido, mediante avaliação da sucção não-nutritiva e observação direta do desempenho do recém-nascido na mamada. Os dados foram descritos por meio de frequências simples e relativas (percentuais) quando categóricas ou média, máximo, mínimo e desvio padrão quando contínuas, discretas ou ordinais. Para avaliar diferenças de média foi utilizado o teste T de Student com nível de significância de 5%. Resultados: houve diferenças significativas entre movimentação da mandíbula do recém-nascido e aspectos da pega ("boca do bebê pouco aberta" p=0,005), sucção ("esforço da bochecha durante a mamada" p<0,001) e posicionamento da díade mãe e recém-nascido ("mamas apoiadas com os dedos na aréola" p=0,041 e bebê com pescoço ou tronco torcidos" p=0,041). Conclusões: recém-nascidos que apresentaram alterações na movimentação da mandíbula na Sucção Não Nutritiva (SNN) tiveram também dificuldade na realização da mamada. O conhecimento do padrão de sucção do recém-nascido, através da avaliação da SNN mostrou-se como estratégia importante que pode auxiliar na identificação de possíveis dificuldades do recém-nascido durante a mamada.

RESUMO

Através de uma Revisão da Literatura, o trabalho busca consolidar informações sobre o desenvolvimento do sistema estomatognático, durante a vida intrauterina. Foram realizadas pesquisas sobre o tema abordado, nas seguintes bases de dados: Scielo, Medline; Bireme; Google Acadêmico e o PubMed, no intervalo de tempo de agosto de 2006 a junho de 2017. Livros publicados no mesmo período também foram consultados. Foram selecionados os artigos em português ou inglês, que contemplaram assuntos inerentes ao estudo. O desenvolvimento do sistema estomatognático acontece a partir do primeiro mês gestacional. A exposição materna a fatores de risco como infecções, traumatismos, desnutrição e consumo de drogas, pode deixar sequelas no feto, comprometendo estruturas e funções buco-dentais.


Through a Literature Review, this work aims to consolidate information about the development of the stomatognathic system during the intrauterine life. The development of the stomatognathic system happens from the first gestational month. Maternal exposure to risk factors, such as infections, trauma, malnutrition, drug use, may leave sequels in the fetus and may compromise buccal-dental structures and functions.

RESUMO

PURPOSE: This study aims to characterize the orofacial myofunctional profile of patients with sleep disorders and to relate them to the severity of the polysomnography result. METHODS: A cross-sectional, field study of patients referred to polysomnography with a random sample of adult patients of both genders complaining of snoring who were not receiving any form of treatment for sleep disorder. An anthroposcopic speech-language evaluation was performed and the results of the polysomnography examination were collected in order to respond to the objectives of the study. RESULTS: There was a significant association between the severity of the sleep disorder and environmental variables, such as smoking and alcoholism; also with individual characteristics, such as race, body mass index, waist circumference and systemic arterial hypertension. From the point of view of the myofunctional characteristics, there was a positive relationship between the severity of Obstructive Sleep Apnea and Hypopnea Syndrome with mental muscle contraction, Mallampati class, tongue dorsum elevation, tongue thickness, uvula characteristics, extension and mobility of the soft palate, and alteration in the respiratory pattern. CONCLUSION: This study made it possible to describe a trend of the existence of orofacial myofunctional alterations in individuals with Sleep Apnea and Obstructive Hypopnea Syndrome and also revealed that the greater the degree of impairment of orofacial structures, the greater the degree of disturbance is also revealed.

RESUMO

O registro da relação maxilo-mandibular (RMM) é considerado um passo crítico na confecção de novas próteses totais (PT) pois exige uma precisão técnica capaz de permitir o seu reestabelecimento, de forma confortável e equilibrada com a musculatura oral. O registro é obtido em dois planos, um vertical e outro horizontal: o plano vertical é determinado pela dimensão vertical (DV) e o plano horizontal é estabelecido pela relação cêntrica (RC). Ambos recuperam o suporte labial, altura incisal, linha do sorriso e o corredor bucal de forma natural e personalizada. Esse registro pode ser obtido, iniciando pelo arco inferior, seguindo a fisiologia e anatomia orofacial. Nessa técnica, considerase três princípios fisiológicos: crista alveolar, situada sobre o rebordo alveolar, musculatura relacionada que determinará o corredor bucal e posição lingual do rodete e a linha úmida do lábio inferior que determinará a altura do rodete inferior. Dessa forma, este trabalho tem por objetivo descrever por meio de condução de caso clínico a técnica de restabelecimento da RMM em paciente edentado bimaxilar iniciando pelo arco inferior(AU)


The maxillo-mandibular relation (MMR) is considered a critical step in the preparation of new complete denture (CD), since it requires a technical precision capable of allowing its reestablishment, in a comfortable and balanced way with the oral musculature. The register is obtained in two planes, one vertical and one horizontal: the vertical plane is determined by the vertical dimension (VD) and the horizontal plane is established by the centric relation (CR). Both recover the lip support, incisal height, smile line and buccal corridor in a natural and personalized way. This record can be obtained, beginning with the lower arch, following the physiology and orofacial anatomy. In this technique, three physiological principles are considered: alveolar crest, located on the alveolar ridge, related musculature that will determine the buccal corridor and the lingual position of the wax rim and the humid line of the lower lip which will determine the height of the lower wax rim. Thus, this study aims to describe, by way of conducting a clinical case, the technique of restoration of RMM in a bimaxillary edentulous patient starting with the inferior arch(AU)

RESUMO

PURPOSE: To perform the expansion, validation of the content, criterion and construct of an orofacial myofunctional assessment protocol for individuals with cleft lip and palate; and to define evaluation parameters for the instrument use. METHODS: The expansion of the instrument was performed based on the MBGR protocol; the items, sub items and possibilities of answers of the amplified instrument were analyzed for their clarity by seven examiners for the content validation.. Assessment parameters were developed for the use of the instrument in order to minimize the subjectivity. Four examiners compared the aspects of the protocol to those of another instrument for the criterion validation, and the construct validation was performed comparing the results of pre and post orthognathic surgery treatment. The Content Validation Index and the Kappa, Spearman and Wilcoxon Correlation tests were applied for the validations. RESULTS: The mobility, tonicity and sensitivity aspects of the evaluation were added to the protocol and at content validation, 72% of the items were classified as very clear and 28% as clear. A manual with assessment parameters for all items and sub items of the protocol was constructed. The inter-examiner agreement was moderate. In the comparison of the protocols, for the validation of the criterion, a good relation among them was observed. For the validation of the construct the protocol was able to identify outcome after the treatment. CONCLUSION: The protocol was expanded and considered validated in its entirety: content, criterion and construct, and evaluation parameters for its use were established.

RESUMO

BACKGROUND: Neurodegenerative diseases that affect the cerebellum, especially in elderly individuals, cause impairment of motor coordination and quality of life. The presente study evaluated the electromyographic activity and thickness of the right and left masseter and temporal muscles, and the maximum molar bite force of individuals with spinocerebellar ataxia. MATERIAL AND METHODS: Twenty-eight individuals were divided into two groups: those with (n=14) and without (n=14) spinocerebellar ataxia. Data on the masticatory muscles obtained from the electromyographic activity (resting, right and left laterality and protrusion), muscle thickness (maximal voluntary contraction and tensile strength) and maximum bite force (right and left) were tabulated and descriptive analysis using Student's t-test (P ≤ 0.05). RESULTS: In the comparison between groups, greater electromyographic activity was demonstrated for individuals with spinocerebellar ataxia, with a statistically significant difference in protrusion and laterality for the temporal muscles (P = 0.05). There was no statistically significant difference between the groups for masticatory muscles thickness in the conditions evaluated. For maximum molar bite force, the group with spinocerebellar ataxia showed lower bite force (P ≤ 0.05). CONCLUSIONS: The data obtained suggest that spinocerebellar ataxia promotes functional reduction in the stomatognathic system, mainly affecting the electromyographic activity and bite force, hindering chewing, with a resultant alteration of nutritional intake and a decrease of quality of life.

RESUMO

RESUMEN Introducción: la relación entre las maloclusiones y la postura del sistema cráneo cervical ha generado un interés creciente entre los ortodontistas. Objetivo: describir la relación entre la oclusión dentaria y la postura del sistema cráneo-cervical en niños con maloclusiones clase II y clase III. Materiales y métodos: estudio descriptivo transversal. El universo estuvo formado por 19 niños, de 7 a 12 años, con maloclusiones clase II y III de Angle. Ingresados en el Servicio de Ortodoncia de la Facultad de Estomatología de La Habana, en octubre del 2016. Se realizó examen bucal y telerradiografía. Los resultados se presentaron en tablas. Resultados: predominó la clase II de Angle, donde la distoclusión molar fue más marcada en el lado derecho (-2,95 mm) y en la clase III la mesioclusión mayor correspondió al izquierdo (2,25 mm como promedio). En ambas predominó la ½ unidad (36,8 % en clase II). El ángulo cráneo-vertebral y el espacio suboccipital estuvieron dentro del rango normal; 104,65º y 7,99 mm, en clase II y en clase III, 103,78º y 6,90 mm como promedio. La profundidad de la columna cervical fue 6,26 mm y 6,20 mm respectivamente; lo que significó una rectificación de columna cervical. Conclusiones: se encontró más frecuente la clase II de Angle. La posición de la cabeza fue normal en ambas clases y la columna cervical rectificada. Se identificaron relaciones inversas entre la magnitud de la maloclusión con la posición de la cabeza y la columna cervical.


ABSTRACT Introduction: the relationship between malocclusions and the crania-cervical system posture has generated a a growing interest among orthodontists. Objective: to describe the relationship between dental occlusion and the position of the crania-cervical system in children with class II and class III malocclusions. Materials and methods: cross-sectional, descriptive study. The universe was 19 children, aged from 7 to 12 years, class II and III Angle's malocclusions, admitted in the Orthodontics service of the Faculty of Stomatology of Havana in October 2016. Oral examination and teleradiography were performed. The results were presented in tables. Results: Class II of Angle predominated, where the molar distoclusion was more marked on the right side (-2.95 mm) and in class III the greater mesioclusion corresponded to the left (2.25 mm as average). In both, the ½ unit predominated (36.8% in Class II). The cranio-vertebral angle and the suboccipital space were within the normal range; 104.65º and 7.99 mm in class II and in class III 103.78º and 6.90 mm as average. The depth of the cervical spine was 6.26 mm and 6.20 mm respectively; which meant a rectification of the cervical spine. Conclusions: Angle's Class II was found more frequent. The position of the head was normal in both classes and also the rectified cervical spine. Inverse relationships were identified between the magnitude of the malocclusion and the position of the head and cervical spine. The objective of this work is to present a clinical case and the importance of a nurse intervention.

RESUMO

BACKGROUND: In the past few years, growing interest was given to the relationship between the dental occlusion and the body balance. While most research focused on this relationship at static conditions, it is evident that the contribution of the sensory information for balance control is different depending on the environmental constraints. RESEARCH QUESTION: The aim of the present paper was to elucidate whether the stomatognathic system (SS) contributes differently on body balance regulation according to the presence of external disturbances. METHODS: Literature regarding the different sources involved in the proprioceptive information to the SS was reviewed. The influence of dental occlusion on balance control at different external environments was then explored. RESULTS: The main findings are: (a) a plausible evidence between the masticatory and cervical muscles can be described; (b) a reciprocal connection between the trigeminal and vestibular nuclei supports the influence of the SS on body balance; (c) traditionally, research involving the relationship between the SS and balance control has focused on strictly controlled situations, thus, ignoring the sensory reweighting which occurs depending on the external disturbances; and (d) the afferences of dental occlusion for balance control seem strengthened when more difficult conditions are present. CONCLUSION: Results of the present review suggest that afferent signals from dental occlusion effectively contribute to balance control when more external perturbations are present, that is unstable support surface, fatigue and tasks being performed. However, more studies are needed to elucidate the mechanisms by which dental occlusion may influence balance control focusing on different external environments.

RESUMO

STATEMENT OF PROBLEM: About 10% of patients with amyotrophic lateral sclerosis (ALS) are candidates for oral treatment specifically because of traumatic injuries in the lips, cheeks, or tongue due to self-biting. However, patients with ALS have a prevalence of temporomandibular disorder (TMD) similar to that in the general population. PURPOSE: The purpose of this case-series study was to determine the degree of satisfaction of patients with ALS with an oral appliance for managing oral self-biting lesions or symptoms related to TMDs. This study also assessed the degree of improvement of the chief complaint and the compliance with and adverse effects of this treatment. MATERIAL AND METHODS: Eleven patients with ALS who sought oral treatment because of oral self-biting or TMD-related symptoms were included. A custom complete-coverage acrylic resin device was fabricated and fitted to each participant. A follow-up visit was planned for 3 months after the placement of the oral appliance, at which point the patients would rate the degree of improvement or worsening of the chief complaint and their degree of satisfaction with the treatment. A 1-sample t test was used to assess whether the degree of improvement of the chief complaint was significant. RESULTS: Participants reported a mean of 61% (95% confidence interval [CI] 38% to 84%) improvement of the chief complaint and a mean of 84% (95% CI 72% to 97%) satisfaction with the treatment. The mean rate of compliance was 62% (95% CI 40% to 84%) of the recommended time, and only a few adverse effects were reported. CONCLUSIONS: Participants with ALS were highly satisfied with the use of an oral appliance to manage oral self-biting or TMD-related symptoms. Adherence to this treatment was high, and no major adverse effects were observed.

RESUMO

PURPOSE: To compare the masticatory efficiency (ME), maximum voluntary bite force (MBF), masseter muscle thickness (MMT), and salivary flow rates (SFR) in completely edentulous dependent elders treated either with a conversion of their existing mandibular complete removable dental prostheses (CRDPs) into a two-implant overdenture (IOD) or a conventional reline of the CRDP. MATERIAL AND METHODS: Participants were randomly allocated into intervention (IG) and control (CG) groups. The IG received two implants in the mandibular canine regions, and their CRDPs were transformed into IODs. The CG received a conventional reline of their mandibular CRDPs. Outcomes were recorded at each recall visit (baseline, immediately, 3 months, 12 months after intervention, and subsequently on an annual basis). Statistical analyses used mixed linear regression models (level of significance: p < 0.05). RESULTS: The IG comprised 16 participants (age = 85.0 ± 6.2 years), while the CG comprised 16 (age = 84.8 ± 5.4 years), with a mean follow-up of 2.7 ± 2.2 years (range: 3 months-7 years). A significant increase of MBF in the IG was observed with an overall gain of 80 N (p < 0.001) compared with the reline group. There were no significant long-term changes in SFR, MMT, or ME within/between groups. CONCLUSION: Since dependent elders with mandibular IODs present a significant gain in MBF, but no relative increase in SFR, MMT, and ME, it seems that this increased capacity of MBF is not exploited by the elders during their habitual chewing.

RESUMO

Abstract Objectives : To evaluate the functional and physiological structures of the stomatognathic system of the oral cavity of older adults based on self-perception, comparing the same with a professional clinical evaluation, and investigating the difficulties encountered when chewing. Method : An analytical cross-sectional study with a quantitative approach was conducted with a sample of 53 older adults aged 60 to 90 years. A protocol consisting of three questionnaires was used: a sociodemographic evaluation, a self-perception based interview with 19 questions on the chewing of the older adults and a clinical evaluation containing 30 questions covering aspects of the oral cavity tissue. The self-perception and clinical evaluation scores were compared using the Mann-Whitney test and the proportions observed for each item were compared by the binomial test. Results : It was found that the self-perception of older adults did not correspond to the result of the clinical evaluation. While 31 (58.5%) reported satisfaction with chewing, 16 (30.2%) had high/very high impairment and 14(26.4%) moderate impairment, based on the results of the clinical evaluation found. Conclusion : It was found that the chewing analysis process cannot be exclusively based on the answers provided by the older adults, and assessment proved to be more accurate when combined with a clinical evaluation performed by a professional.


Resumo Objetivos : Avaliar as estruturas funcionais e fisiológicas do sistema estomatognático da cavidade bucal dos idosos diante da autopercepção, comparando-as com a avaliação clínica profissional e investigar as dificuldades encontradas para realizar sua mastigação. Método : Estudo transversal analítico de abordagem quantitativa, realizado com uma amostra de 53 idosos, idade entre 60 e 90 anos. Foi utilizado um protocolo constituído de três questionários: uma avaliação sociodemográfica, uma entrevista de autopercepção com 19 quesitos da mastigação do idoso e uma avaliação clínica contendo 30 quesitos abrangendo os aspectos teciduais da cavidade bucal. Os escores da autopercepção e da avaliação clínica foram comparados pelo teste de Mann-Whitney e as proporções observadas para cada item pelo teste binomial. Resultados : Constatou-se que a autopercepção relatada pelos idosos não correspondeu ao resultado da avaliação clínica. Enquanto 31 (58,5%) relataram satisfação com a mastigação, 16 (30,2%) possuíam comprometimento alto/muito alto e 14 (26,4%) comprometimento moderado. Conclusão : Evidenciou-se que o processo de análise da mastigação não pode ser realizado exclusivamente pelas respostas prestadas pelo idoso, sendo mais adequado quando se adiciona a etapa da avaliação clínica feita por um profissional.
