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

BACKGROUND: Difficulties and limitations on masticatory function are among the main reasons why patients with temporomandibular disorder (TMD) seek care. OBJECTIVE: To evaluate the masticatory behaviour and perception of chewing difficulties in adults with mild TMD of recent onset, considering the presence of malocclusion. METHODS: Eighty-one young adults were divided into groups according to the presence of TMD and malocclusion: Non-TMD Normal Occlusion (n = 18), Non-TMD Malocclusion (n = 22), TMD Normal Occlusion (n = 18) and TMD Malocclusion (n = 23). TMD was assessed using the TMD Research Diagnostic Criteria and volunteers also answered questionnaires regarding their perception about jaw functional limitation and difficulty to chew foods of different textures. Masticatory and swallowing behaviours were assessed using the Orofacial Myofunctional Evaluation with Scores (OMES) protocol. Chewing time and chewing frequency taken to ingest the test-food were also obtained. Two-way-ANOVA was used to analyse the TMD, occlusion and TMD × occlusion interaction effects. RESULTS: Temporomandibular disorder effect was observed on vertical jaw mobility and jaw function limitation total scores, meaning that groups differed in the perception of opening limitation and mandibular limitation according to TMD status with a medium effect size. Also, more changes in chewing function (OMES-chewing score) and higher chewing frequency was observed in the presence of TMD (P < 0.05). Occlusion effect was only observed on OMES-swallowing score and no TMD × occlusion interaction effect was observed. CONCLUSION: Changes in chewing behaviour, frequency and perception of mandibular limitation was observed in the presence of TMD, pointing out the importance of functional evaluation when planning and establishing a treatment plan.

RESUMO

Introduction Studies in the fields of voice and speech have increasingly focused on the vocal tract and the importance of its structural integrity, and changes in the anatomy and configuration of the vocal tract determine the variations in phonatory and acoustic measurements, especially in the formation of the formants (Fs). Recent studies have revealed the functional consequences arising from being overweight and having an accumulation of fat in the pharyngeal region, including obstructive sleep apnea syndrome (OSAS) and impacts on the voice. Objectives To assess the relationship between body mass index (BMI) and analysis of the speech. Methods This study was approved by the Ethics Committee of the Universidade Federal de São Paulo (no. 288,430). The cohort consisted of 124 individuals aged between 18 and 45 with full permanent dentition and selected randomly. The participants underwent a brief medical history taking, BMI assessments and recording emissions of the sustained vowels /a/, /ε/, /i/, and /u/ by acoustic program PRAAT (v. 5.3.85, Boersma and Weenink, Amsterdam, Netherlands). Recordings were taken using a unidirectional microphone headset (model Karsect HT-9, Guangdong, China), with a condenser connected to an external sound card (USB-SA 2.0, model Andrea, PureAudio™, Pleasant Grove, UT, USA), to reduce noise. Results There was a significant correlation between BMI and formant 3 (F3) vowel /a/; however, there was a low degree of correlation intensity. Conclusions We did not observe a correlation between the BMI and the speech formants, but we believe there is a trend in this correlation that leads to changes in speech patterns with increases in BMI.

RESUMO

The evaluation of mastication is important to understand the masticatory behavior and diagnose feeding difficulties. The objective of this preliminary study was to verify if there is agreement between objective and subjective validated methods of chewing evaluation in a convenience sample which consisted of 32 adolescents (mean 15.5years), complete permanent dentition and free of tooth decay. The Quality of Masticatory Function Questionnaire with the Food-Mastication, Habits, Meat, Fruit and Vegetables domains was used in the subjective evaluation. The objective aspects consisted of maximum bite force (BF) and masticatory performance (MP) by mastication of cubes of test-material and sieving to determine the median particle size (X50) and distribution in the sieves ("b"), and by the colorimetric method using colorchangeable chewing gum. Data were submitted to exploratory analysis, normality test and correlation tests (Pearson/Spearman). The correlation between BF and X50 (r=-0.43; p=0.02) and between BF and MP chewing gum (r=0.53; p=0.002) was significant with large effect size. The MP evaluated by chewing gum correlated with X50 (r=-0.34; p=0.055), but not with "b" (r=-0.06; p=0.73), while "b" correlated only with X50 (r=0.52, p=0.002). No significant correlation was observed between the objective measures and the total score of the subjective evaluation; only a negative correlation was observed between "b" and Meat domain (r=-0.40; p=0.023). The objective methods showed moderate correlation with each other and no agreement between the objective and subjective methods was observed in this sample of healthy adolescents, emphasizing the importance of both aspects in the evaluation of masticatory function.

RESUMO

RESUMO Objetivo: analisar a força axial da língua e parâmetros relacionados por meio do FORLING. Método: foram analisados os dados de 92 participantes, entre homens e mulheres, com média de 23,3±7,7 anos. Resultados: no parâmetro força média da língua, identificaram-se valores médios de 13,0 N, já para a força máxima observou-se valor médio de 18,3 N. A força média e a máxima da língua apresentaram correlação positiva e associação altamente significante (p<0,001). A energia acumulada pela língua indicou valores de 131,1 N/s. O tempo médio gasto para que se alcance a força máxima da língua foi de 3,8 segundos, indicando um efeito do treinamento ao se comparar a 1ª à 3ª medida, com redução dos valores (p<0,001). Conclusão: o instrumento demonstrou ser capaz de mensurar parâmetros importantes para o fonoaudiólogo, indicando ser uma promissora ferramenta complementar à avaliação clínica fonoaudiológica.


ABSTRACT Purpose: to analyze axial tongue strength and related parameters by using the Forling. Methods: data regarding 92 participants, including men and women with a mean age of 23.3 ± 7.7 years, were analyzed. Results: the mean value of the mean tongue strength was 13.0 N, and the maximum strength value was 18.3 N. The mean and maximum tongue strengths showed positive correlation and highly significant association (p < 0.001). The energy accumulated by the tongue was 131.1 N/s. The mean time required for the maximum tongue strength to be reached was 3.8 s, and the decrease in time (p < 0.001) from the first to the third measurements indicates an effect of training. Conclusion: the instrument proved to be capable of measuring parameters that are important to the speech-language pathologist, indicating that it can be a promising complementary tool for clinical evaluation.

RESUMO

PURPOSE: Few studies have investigated myofunctional therapy in patients with obstructive sleep apnea syndrome (OSAS). The objective of this study was to evaluate the effect of myofunctional therapy on continuous positive airway pressure (CPAP) adherence. METHODS: The study was registered at ClinicalTrials.gov (NCT01289405). Male patients with OSAS were randomly divided into four treatment groups: placebo, patients undergoing placebo myofunctional therapy (N = 24); myofunctional therapy, undergoing myofunctional therapy (N = 27); CPAP, undergoing treatment with CPAP (N = 27); and combined, undergoing CPAP therapy and myofunctional therapy (N = 22). All patients underwent evaluations before and after 3 months of treatment evaluation and after 3 weeks of washout. Evaluations included Epworth sleepiness scale (ESS), polysomnography, and myofunctional evaluation. RESULTS: The 100 men had a mean age of 48.1 ± 11.2 years, body mass index of 27.4 ± 4.9 kg/m2, ESS score of 12.7 ± 3.0, and apnea-hypopnea index (AHI) of 30.9 ± 20.6. All treated groups (myofunctional therapy, CPAP, and combined myofunctional therapy with CPAP) showed decreased ESS and snoring, and the myofunctional therapy group maintained this improvement after the "washout" period. AHI reduction occurred in all treated groups and was more significant in CPAP group. The myofunctional therapy and combined groups showed improvement in tongue and soft palate muscle strength when compared with the placebo group. The association of myofunctional therapy to CPAP (combined group) showed an increased adherence to CPAP compared with the CPAP group. CONCLUSIONS: Our results suggest that in patients with OSAS, myofunctional therapy may be considered as an adjuvant treatment and an intervention strategy to support adherence to CPAP.

RESUMO

Introduction Aglossia is a rare condition caused by failure of the tongue embryogenesis process (in the fourth to eighth weeks of gestation). The tongue is an organ used in different activities such as sucking, swallowing, chewing, and talking. It is also responsible for shaping palate dental arches (in its absence, they become atrophic). There are few similar cases reported in the literature. Objective To describe a rare case of aglossia and the multidisciplinary professionals working together for 5 years to treat the patient. Resumed Report An 8-year-old girl with aglossia had an assessment comprising: (1) clinical assessment of the stomatognathic system related to resting posture, tonus, and mobility; (2) orthodontic assessment; (3) surface electromyography of the chewing muscles; (4) swallowing videofluoroscopy. Conclusion The authors confirmed the need of multidisciplinary cooperation to improve the patient s quality of life, because agenesia implicates many activities/ functions that depend on the tongue to fully work. Multiprofessional cooperation helps the patient learn compensation mechanisms.

RESUMO

Introdução: a preferência mastigatória (PM) é o lado mais usado pelo indivíduo durante o ato de mastigação, que pode estar relacionado com a força máxima da mordida (FMM), que é a máxima força exercida pelo indivíduo durante a fragmentação dos alimentos e é determinada por muitos fatores. Objetivo: analisar a FMM de indivíduos, em diferentes faixas etárias..segundo a PM. Métodos: a amostra constitui em 80 indivíduos, divididos igualmente entre sexo e faixa etária. Cada indivíduo fou submetido a uma avaliação miofuncional, composta por uma avaliação clínica associada à anamnese sobre PM, medidas antropométricas de peso e altura, de onde foi extraído o IMC, avaliação das condições dentárias e avaliação da força máxima de mordida, usando um dinamômetro modelo DDK/M (Kratos, Cotia/SP), na esala N. A avaliação dentária e fa força de mordida foram monitoradas por um profissional da área. Após o computo dos dados, foram submetidos à análise estatística.Resultado: foi observada maior FMM do lado direito em indivíduos que relataram ter PM à direita, e uma tendência para PM à esquerda com maior FMM para o mesmo lado. Conclusão: a PM à direita determina a FMM, o que não acontece com idade, sexo e IMC.

RESUMO

OBJETIVO: analisar a máxima força de mordida na oclusão normal e maloclusões de Angle; observar a frequência de ocorrência dos tipos de oclusões; analisar a existência de diferença entre as medidas desta força e relacionar a força de mordida com índice de massa corpórea (IMC) de cada indivíduo. MÉTODOS: a amostra foi composta por 100 estudantes do curso de Fonoaudiologia, com faixas etárias entre 17 e 25 anos. Cada indivíduo realizou: 1) Anamnese: composta por dados de identificação pessoal, informações sobre alimentação diária; preferência mastigatória; peso e altura. 2) Classificação da oclusão dentária em: normal ou Classe I, II subdivisão 1ª e 2ª ou Classe III. 3) Avaliação da força de mordida por meio de um dinamômetro digital. Os resultados foram submetidos aos testes estatísticos: Kolmogorov-Smirnov, T-Student Pareado, Teste de Igualdade de Duas Proporções, Teste ANOVA, Comparação Múltipla de Tukey e Teste de Spearman. RESULTADOS: as maiores forças de mordida foram obtidas nos indivíduos com oclusão normal, seguida das maloclusões Classes I, II subdivisão 1ª e 2ª e III, respectivamente; houve maior frequência de ocorrência da maloclusão Classe I, seguida da oclusão normal, maloclusão Classes II subdivisão 1ª e 2ª e III; houve aumento da força média entre a primeira e terceira medida em ambos os lados; não houve correlação entre força de mordida e o índice de massa corpórea (IMC). CONCLUSÃO: o tipo de oclusão influenciou na força de mordida, sendo a maior força obtida após a terceira mensuração e não houve relação entre IMC e força de mordida. .


PURPOSE: to analyze the maximum bite force in individuals with normal occlusion and types of Angle’s malocclusion; to observe the frequency of occurrence of each type of occlusion; to analyze whether there is any difference between measurements of force and relate bite force to body mass index (BMI). METHODS: the sample was composed of 100 students of the Speech and Language Pathology School at UNIFESP, with ages between 17 and 25 years. Individuals with ATM disfunctions, mental or genetic disorders and those who had already undergone miotherapy were excluded. Each individual went through an evaluation, which consisted of: 1) gathering personal information, personal diet, chewing preference, weight and height. 2) evaluation of dental occlusion as normal occlusion or malocclusion Class I, Class II 1st division, Class II 2nd division or Class III. 3) evaluation of bite force, performed by using a digital dynamometer. Different techniques were used for statistical analysis. RESULTS: individuals with normal occlusion were those who had the greatest bite force, followed by Classes I, II 1st and 2nd divisions and Class III, respectively; there was higher occurrence of malocclusion Class I, followed by normal occlusion, Class II 1st and 2nd divisions and Class III; There was an increase of the average force between the first and third measurements for both sides; there was no correlation between bite force and BMI. CONCLUSION: the type of occlusion influenced bite force, the greatest force being obtained on the third measurement; there was no relation between BMI and bite force. .

RESUMO

Introduction: Maximum bite force (MBF) is the maximum force performed by the subject on the fragmentation of food, directly related with the mastication and determined by many factors. Objective Analyze the MBF of subjects according to age groups. Methods: One hundred individuals from the city of São Paulo were equally divided according to age groups and gender. Each individual submitted to a myotherapy evaluation composed of anthropometric measurements of height and weight to obtain body mass index (BMI), using a tape and a digital scale (Magna, G-life, São Paulo), and a dental condition and maximum bite force evaluation, using a digital dynamometer model DDK/M (Kratos, São Paulo, Brazil), on Newton scale. The dental and bite force evaluations were monitored by a professional from the area. Analysis of variance was used with MBF as a dependent variable, age group and gender as random factors, and BMI as a control variable. Results: Till the end of adolescence, it was possible to observe a decrease in MBF in both sexes, with the male force greater than the female force. In young adults, the female force became greater the males, then decreased in adulthood. There was no correlation between MBF and BMI. Conclusion: There are MBF variations that characterizes the human development stages, according to age groups...

RESUMO

Objetivo comparar a atividade elétrica dos músculos masseter e temporal, porção anterior, no repouso, contração isométrica voluntária máxima e na mastigação em análise valor original (µv) e em Root Mean Square (RMS). Métodos estudo observacional, descritivo. Foi realizado eletromiografia de superfície nos músculos masseter e temporal, porção anterior, bilateralmente, em 18 mulheres entre 27 e 50 anos de idade. O exame foi realizado em três situações: durante o repouso, na contração isométrica voluntária máxima e mastigação habitual, com uva passa sem semente como alimento. O eletromiógrafo utilizado foi o BIOPAK, da Bioresearch Associates, de quatro canais, modelo 800 e eletrodos bipolares de superfície (Bio Trodo no gel). Os registros do sinal foram obtidos em microvolts, e analisados e comparados em sinal original e em root mean square- RMS. Resultados ao comparar a atividade elétrica dos músculos masseteres e temporais, porção anterior, não foi encontrado diferenças estatisticamente significantes entre os valores originais e RMS durante o repouso. Tanto na contração isométrica voluntária máxima quanto na mastigação habitual, foi encontrado valores maiores de maneira estatisticamente significante para RMS. Houve predomínio de atividade elétrica nos músculos masseteres quando comparado ao músculo temporal, porção anterior, tanto na mastigação quanto na contração isométrica voluntária máxima. Conclusão existe um mínimo de atividade elétrica no repouso. Tanto no apertamento dentário quanto na mastigação de uva passa foi encontrado valores médios de RMS maiores que valores médios originais. Houve maior atividade ...


Purpose to compare the electrical activity of masseter and temporal muscles, (anterior fascicle) at rest, in maximum voluntary isometric contraction and chewing, taking the original value analysis (µ v) and Root Mean Square (RMS). Methods observational and descriptive study. Surface Electromyography was held in the masseter and temporal muscles (anterior portion) bilaterally, in 18 women between 27 and 50 years of age. The assessment was carried out in three situations: at rest, in maximum voluntary isometric contraction and habitual chewing dried vine fruit without seeds, as food. The electromyography used was the BIOPAK, Bioresearch Associates, four-channel, model 800 and bipolar surface electrodes (Bio Trodoon gel). The signal records were obtained in microvolts, and analyzed and compared in the original signal and RMS root mean square. Results when we compare the electrical activity of masseters and temporal muscles (anterior fascicle), there is no statistically significant differences between the original and RMS values at rest. Both in maximum voluntary isometric contraction and habitual chewing, we find statistically significant higher values to RMS. There was a predominance of electrical activity in muscles masseters when compared to the temporal muscle, anterior fascicle, both chewing and in maximum voluntary isometric contraction. Conclusion there is a minimum of electrical activity at rest. Both the tooth clenching and mastication of dried vine fruit we find RMS average values greater than original mean values. There has been greater electrical activity of muscles masseters when compared to the temporal muscle, both in maximum voluntary isometric contraction as chewing. .

RESUMO

Rapid maxillary expansion (RME) is a widely used practice in orthodontics. Scientific evidence shows that RME can be helpful in modifying the breathing pattern in mouth-breathing patients. In order to promote the restoration of physiological breathing we have developed a rehabilitation program associated with RME in children. The aim of the study was a literature review and a model of orofacial rehabilitation in children with obstructive sleep apnea undergoing treatment with rapid maxillary expansion. Muscular training (local exercises and general ones) is the key factor of the program. It also includes hygienic and behavior instructions as well as other therapeutic procedures such as rhinosinusal washes, a postural re-education (Alexander technique) and, if necessary, a pharmacological treatment aimed to improve nasal obstruction. The program should be customized for each patient. If RME is supported by an adequate functional rehabilitation, the possibility to change the breathing pattern is considerably amplified. Awareness, motivation and collaboration of the child and their parents, as well as the cooperation among specialists, such as orthodontist, speech therapist, pediatrician and otolaryngologist, are necessary conditions to achieve the goal.

RESUMO

BACKGROUND: Patients with obstructive sleep apnea (OSA) exhibit reduced quality of life (QoL) due to their daytime symptoms that restricted their social activities. The available data for QoL after treatment with continuous positive airway pressure (CPAP) are inconclusive, and few studies have assessed QoL after treatment with speech therapy or other methods that increase the tonus of the upper airway muscles or with a combination of these therapies. The aim of our study was to assess the effect of speech therapy alone or combined with CPAP on QoL in patients with OSA using three different questionnaires. METHODS: Men with OSA were randomly allocated to four treatment groups: placebo, 24 patients had sham speech therapy; speech therapy, 27 patients had speech therapy; CPAP, 27 patients had treatment with CPAP; and combination, 22 patients had treatment with CPAP and speech therapy. All patients were treated for 3 months. Participants were assessed before and after treatment and after 3 weeks of a washout period using QoL questionnaires (Functional Outcomes of Sleep Questionnaire [FOSQ], World Health Organization Quality of Life [WHOQoL-Bref], and Medical Outcomes Study 36-Item Short-Form Health Survey [SF-36]). Additional testing measures included an excessive sleepiness scale (Epworth sleepiness scale [ESS]), polysomnography (PSG), and speech therapy assessment. RESULTS: A total of 100 men aged 48.1±11.2 (mean±standard deviation) years had a body mass index (BMI) of 27.4±4.9 kg/m(2), an ESS score of 12.7±3.0, and apnea-hypopnea index (AHI) of 30.9±20.6. After treatment, speech therapy and combination groups showed improvement in the physical domain score of the WHOQoL-Bref and in the functional capacity domain score of the SF-36. CONCLUSIONS: Our results suggest that speech therapy alone as well as in association with CPAP might be an alternative treatment for the improvement of QoL in patients with OSA.

RESUMO

OBJECTIVE: To analyze the stability of occlusal changes promoted by the Frankel's Functional Regulator 2 (FR-2), in a mean period of 7.16 years post treatment. METHODS: Fifty-four pairs of models were evaluated, from 18 patients treated with FR-2. All patients had Class II, division 1 malocclusion, with initial mean age of 10.77 years and were treated with FR-2 for 18 months. The models were evaluated at the beginning of treatment (T1), at the end (T2) and after 7.16 years post treatment (T3). For occlusal evaluation, the treatment priority index (TPI) was applied on the three analyzed phases. The alterations that occurred between phases were verified with one another through paired Student's t test, with critical value of 0.05. RESULTS: A statistically significant reduction of TPI was verified, from the initial to the final phase of the treatment, reflecting the efficiency of treatment performed with FR-2, specially due to improvement in molar relation, overjet and overbite. Apart from this, the Class II correction remained stable over time. CONCLUSIONS: In this way, it is concluded that the FR-2 appliance showed to be efficient for the dental correction of Class II malocclusion, with stable occlusal results after 7.16 years post treatment.


OBJETIVO: analisar a estabilidade das alterações oclusais promovidas pelo aparelho Regulador de Função Fränkel-2 (RF-2), num período médio de 7,16 anos pós-tratamento. MÉTODOS: foram avaliados 54 pares de modelos, provenientes de 18 pacientes tratados por meio do aparelho RF-2. Todos os pacientes possuíam má oclusão de Classe II, divisão 1, com idade inicial média de 10,77 anos e foram tratados com o RF-2 por 18 meses. Os modelos foram avaliados no início do tratamento (T1), no final do tratamento (T2) e decorridos 7,16 anos pós-tratamento ativo (T3). Para a avaliação oclusal, aplicou-se o Índice de Prioridade de Tratamento (IPT) nas três fases analisadas. As alterações ocorridas entre as fases foram verificadas entre si por meio do teste t de Student pareado, com o valor crítico adotado de 0,05. RESULTADOS: verificou-se uma diminuição estatisticamente significativa do IPT, da fase inicial à final de tratamento, refletindo a eficácia do tratamento realizado por meio do RF-2, principalmente devido à melhora da relação molar, do trespasse horizontal e vertical. Além disso, a correção da má oclusão de Classe II obtida permaneceu estável no decorrer do tempo. CONCLUSÃO: concluiu-se que o aparelho RF-2 demonstrou ser eficaz na correção dentária da má oclusão de Classe II, com resultados oclusais estáveis decorridos 7,16 anos pós-tratamento.

RESUMO

INTRODUCTION: This study evaluated changes in the smile characteristics of patients with maxillary constriction submitted to rapid maxillary expansion (RME). METHODS: The sample consisted of 81 extraoral photographs of maximum smile of 27 patients with mean age of 10 years, before expansion and 3 and 6 months after fixation of the expanding screw. The photographs were analyzed on the software Cef X 2001, with achievement of the following measurements: Transverse smile area, buccal corridors, exposure of maxillary incisors, gingival exposure of maxillary incisors, smile height, upper and lower lip thickness, smile symmetry and smile arch. Statistical analysis was performed by analysis of variance (ANOVA), at a significance level of 5%. RESULTS: RME promoted statistically significant increase in the transverse smile dimension and exposure of maxillary central and lateral incisors; maintenance of right and left side smile symmetry and of the lack of parallelism between the curvature of the maxillary incisal edges and lower lip border. CONCLUSIONS: RME was beneficial for the smile esthetics with the increase of the transverse smile dimension and exposure of maxillary central and lateral incisors.


INTRODUÇÃO: esse estudo avaliou as alterações das características do sorriso de pacientes com atresia maxilar submetidos à expansão rápida da maxila (ERM). MÉTODOS: a amostra consistiu de 81 fotografias extrabucais do sorriso máximo de 27 pacientes, com idade média de 10 anos, antes da expansão e aos três e seis meses após a fixação do parafuso expansor. As análises das fotografias foram realizadas por meio do programa Cef X 2001, e as seguintes medidas foram analisadas: dimensão transversal do sorriso, corredores bucais, quantidade de exposição dos incisivos superiores, exposição gengival dos incisivos superiores, altura do sorriso, espessuras dos lábios superior e inferior, simetria e arco do sorriso. As alterações no sorriso durante as diferentes fases foram avaliadas por meio da análise de variância (ANOVA), seguida pelo teste de comparações múltiplas de Bonferroni, com nível de significância de 5%. RESULTADOS: a ERM promoveu aumento estatisticamente significativo da dimensão transversal do sorriso e da quantidade de exposição dos incisivos centrais e laterais superiores; manutenção da simetria entre os lados direito e esquerdo e da falta de paralelismo entre a curvatura das bordas dos incisivos superiores e a do lábio inferior. CONCLUSÃO: a ERM beneficiou a estética do sorriso com o aumento da dimensão transversal do sorriso e da quantidade de exposição dos incisivos centrais e laterais superiores.

RESUMO

PURPOSE: To analyze the maximum axial force, the mean axial force, the amount of energy accumulated by the tongue, and the time taken to reach the maximum axial force, in different age ranges. METHODS: The records of 92 individuals - students, staff and visitors at an university -, 29 (32.6%) men and 63 (67.4%) women, with ages between 14 and 53 years old, were analyzed. Subjects were divided into four age groups: 14 to 18 years, 19 to 23 years, 24 to 28 years, and 29 to 53 years. Each subject underwent clinical and instrumental assessment of the tongue. Instrumental assessment used FORLING. Data were statistically analyzed. RESULTS: Regarding the maximum force, the mean force and the tongue's accumulated energy, no differences were observed between groups. Regarding the time taken to reach the maximum force, the greatest values were obtained at the age range from 14 to 18 years (4.5 s), and the shortest values, at the age range from 19 to 23 years (3.1 s), with significant difference between the groups (p=0.001). CONCLUSION: Only the time taken to reach the tongue's maximum force is influenced by age range, indicating that teenagers are not able to reach the maximum lingual force as fast as young adults.
