Purpose: To analyze the difference between nonsmokers and smokers on the changes in the perceptions of smell and taste and to verify the influence of these aspects in the emergence of compensatory movements during swallowing. Methods: To evaluate these aspects, capabilities of olfactory and gustatory recognition were observed, as well as the compensation swallowing. Twenty-four patients were evaluated in each study group aged from 18 years, grouped in a stratified way. The olfactory evaluation consisted in presenting seven essences and one of three options should be chosen. For the taste test, 16 flavors were offered in a non-sequential and decreasing way in amount of solute. Swallowing solid and liquid was evaluated, in which aspects of compensation perioral muscles were observed. Results: Worst performance in olfactory and gustatory tests among smokers (p≤0.01) was found. Through the results of χ2 and Fisher's exact tests, it was found that the contraction of the mentalis muscle is less observed in non-smokers, and smokers have an average degree of statistically significant change compared to nonsmokers. Furthermore, through the Spearman correlation coefficient, it was found that the worsening in the sensory tests implies increased compensation during swallowing in smokers. Conclusion: These data allowed us to verify that the sensory changes have influence on swallowing pattern, indicating that these changes are aspects that should be considered in the differential diagnosis of changes in swallowing.

Simplified clinical examination of swallowing by dentists was found to be an accurate method to screen dysphagia in older persons.

Resumo: Objetivou-se avaliar a associação entre presença de Centros de Especialidades Odontológicas (CEO) e a proporção de exodontias em relação ao total de procedimentos odontológicos em serviços públicos do Brasil. Trata-se de um estudo ecológico, em que foram avaliados dados sociodemográficos, dos serviços de saúde bucal e produção ambulatorial de 5.333 municípios nos biênios de 2000/2001 e 2015/2016. A principal variável de exposição foi a presença de CEO, e o desfecho a média nacional da proporção de exodontias em relação ao número de procedimentos odontológicos preventivos e curativos. Foram realizadas análises de interação e regressão múltipla usando modelo binomial com função de ligação logito. A média nacional da proporção de exodontias em relação aos procedimentos odontológicos preventivos e curativos foi 27,07% e 15,11% em 2000/2001 e 2015/2016, respectivamente. Na análise de interação entre a presença de CEO e a cobertura superior a 80% de equipes de saúde bucal (ESB), houve menores proporções de exodontias em relação aos procedimentos odontológicos preventivos e curativos (OR = 0,71; IC95%: 0,71-0,72). Na análise de regressão múltipla, municípios com Índice de Desenvolvimento Humano entre 0,6-0,7 (OR = 0,77; IC95%: 0,77-0,77), Produto Interno Bruto per capita maior que 20 mil Reais (OR = 0,45; IC95%: 0,45-045) e maior população residente em zona urbana (OR = 0,72; IC95%: 0,72-0,72) apresentaram menor proporção de exodontias em relação aos procedimentos odontológicos preventivos e curativos em 2015/2016. Conclui-se que ocorreram menores proporções de exodontias em relação aos procedimentos odontológicos preventivos e curativos em municípios com ao menos um CEO e com mais de 80% de cobertura de ESB, o que aponta que municípios com Rede de Atenção à Saúde Bucal consolidada têm melhor desempenho na oferta de cuidados odontológicos.

Introduction For chewing to occur properly, it is necessary that all oral structures are present and of normal standard. Objectives The aim of this study is to verify the presence of oral changes in smokers and the impact of the changes on masticatory function compared with individuals who never smoked. Methods Forty-eight subjects were evaluated, split into two study groups (24 subjects each) of current tobacco users and individuals who have never smoked. The variables halitosis, presence of lesions suggestive of caries and periodontal problems, number of teeth, classification of malocclusions according to angle, standard grinding food, chewing pattern, and speed of chewing were evaluated. Results There was no statistically significant difference in tooth loss between the groups, but the smokers had more losses manifesting malocclusion. Most smokers had halitosis and lesions suggestive of caries and periodontal problems; the halitosis was associated with the latter variable. Masticatory speed was also reduced significantly in these individuals compared with the control group when associated with occlusal alterations, in addition to grinding food with the tongue. No difference was observed regarding the chewing pattern. The presence of halitosis and periodontal problems were more common in those who smoke more than 20 years. Conclusion There is an association between smoking and dental changes, which cause increased masticatory changes.

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.

Introduction Voice modification after swallowing may indicate changes in the transit of the bolus. Objective The aim of this study is to verify the use of perceptual voice analysis to detect oropharyngeal dysphagia. Study Design Case series. Methods Twenty-seven patients with dysphagia as diagnosed by videofluoroscopy and 25 without were evaluated. The sustained vowel /a/ was recorded before this exam and after swallowing different consistencies (pasty, liquid and solid). For the voice evaluation, the GRBAS scale (grade, roughness, breathiness, asthenia and strain) and the parameter “wet voice” were used. Three judges blinded to study group and time of emission performed voice analysis. Results Individuals with dysphagia showed significant decrease in grade of voice and asthenia and increase in strain after swallowing pasty substances, differing from individuals without dysphagia who showed no modification of the parameters after swallowing. The wet voice parameter showed no difference after swallowing in both study groups. Conclusion The decrease in grade and asthenia and increased strain are indicative of a swallowing disorder, indicating increased vocal strain to clean the vocal tract of food. The modification of vocal production after swallowing proved to be a trusted resource for detection of swallowing disorders.

RESUMO Objetivo Verificar se a modificação da voz após a deglutição relaciona-se com os dados do exame de videofluoroscopia. Método 27 indivíduos com disfagia orofaríngea realizaram a gravação da vogal sustentada /a/ antes e após a deglutição durante exame de videofluoroscopia. Utilizou-se a escala GRBAS e acrescentou-se o aspecto voz molhada para avaliação dos dados. Em relação ao exame, verificou-se estase de alimento em valéculas e recessos piriformes, penetração laríngea, aspiração traqueal e grau de disfagia. Resultados Houve diminuição do grau de alteração e astenia e aumento da tensão fonatória após a deglutição, sem diferença para o parâmetro voz molhada. Obteve-se sensibilidade e especificidade de ±50% para estase em recessos piriformes e valéculas; porém, sensibilidade de 80% para detecção de penetração e de 66-75% para aspiração e modificação da tensão fonatória, com 77-91% de valores preditivos negativos para os três parâmetros de avaliação, sem correlação com o grau de disfagia. Conclusão A modificação dos parâmetros da escala GRBAS após a deglutição apresentou boa compatibilidade com achados da videofluoroscopia.
