[Prevalence of poor self-rated mastication and associated factors in Brazilian elderly]

Masticatory Adaptation to Occlusal Changes

This review deals with the frequent wide variability of masticatory capacity/incapacity. Neither researchers nor clinicians have taken sufficient account of this variability despite its implications for nutrition. Mastication in normal healthy oral conditions is first described, followed by a short presentation of the mechanisms of masticatory adaptation in the nervous system. Capacity, incapacity, and successful compensatory adaptation of mastication are then defined, along with the different methods used for their evaluation. Examples of adaptation needs are given, such as those concomitant with dental wear or occlusal changes. Finally, given its vital importance for deeply impaired mastication/deglutition function, the impact of masticatory adaptation processes on nutrition is examined.

Income inequalities in oral health and access to dental services in the Brazilian population: National Health Survey, 2013

INTRODUCTION

Despite the improvement in oral health conditions observed in the Brazilian population, there are still high social inequalities that must be monitored.

OBJECTIVE

To evaluate income inequality in oral hygiene practices, oral health status and the use of dental services in the adult and senior Brazilian population.

METHODS

Data from the National Health Survey conducted in 2013 (Pesquisa Nacional de Saúde - PNS 2013) were used for the population aged 18 years old or older.

RESULTS

Inequalities were found among the income strata in most of the oral health indicators evaluated. The greatest inequalities were observed in the use of dental floss, in hygiene practices (PR = 2.85 in adults and PR = 2.45 in seniors), and in total tooth loss (PR = 6.74 in adults and PR = 2.24 in seniors) and difficulty in chewing (PR = 4.49 in adults and PR = 2.67 in seniors) among oral condition indicators. The magnitude of inequalities was high in both groups in most oral condition indicators. Income was a factor that persisted in limiting access to dental services, and even the lower income segments had high percentages that paid for dental consultations.

CONCLUSION

Based on data from the first PNS, the findings of this study enabled the identification of oral health and dental care aspects more compromised by income differentials, thus, contributing to the planning of dental care in Brazil and to stimulate the monitoring of these disparities with data from future surveys.

Screening for masticatory disorders in older adults (SMDOA): An epidemiological tool

PURPOSE

Masticatory changes in the older adult population may cause nutritional impairment, so epidemiological studies are important to allow specific public health interventions. Thus, this study aims at constructing and validating an instrument for screening for masticatory disorders in older adults (SMDOA).

METHODS

Validation study. First step: validity evidence based on test content. Defining the construct and elaborating the questions by a panel of experts and evaluating the representativeness and relevance of the items in relation to the construct by a committee of 28 experts. Analysis was performed through the Content Validity Index for Items (CVI-I) and the Content Validity Index (CVI). Second stage: validity evidence based on response processes. The questionnaire was applied to 40 older adults (≥60 years) using the cognitive interview strategy. Quantitative and qualitative analysis of the responses was carried out. Third stage: validity evidence based on the internal structure. The instrument was applied to 295 older adult patients and a confirmatory factorial analysis was performed to fit the model.

RESULTS

The first version of SMDOA consisted of 16 issues related to chewing. The CVI and CVI-I were satisfactory, and only one question was excluded. The instrument with 15 questions was well evaluated by the older adults, only requiring minor adjustments to the morphosyntax. After the confirmatory factorial analysis, adjustments were made in its internal structure resulting in the 9-question model in two factors regarding function and masticatory perception.

CONCLUSIONS

The SMDOA presented good evidence of validity in its content, response processes and internal structure.

Prevalence of chewing difficulty among adults and associated factors

The aim of this study was to estimate the prevalence of chewing difficulty and associated factors in adults aged 20 to 59 years in Patos, in the State of Paraiba in the Northeast Region of Brazil. A cross-sectional study was conducted with a random sample of 532 participants. The outcome chewing impairment was assessed using the question "How often do you have difficulty eating due to problems with your teeth or dentures?". Crude and adjusted prevalence ratios were estimated using Poisson regression. The prevalence of chewing difficulty was 30.5%. An association remained between the following variables and chewing difficulty in the final multivariate models: age group, schooling, being a smoker/non-smoker, length of time since last visit to the dentist, severe tooth loss, absence of functional dentitions, dental prosthesis use, need for a dental prosthesis, oral pain, and signs and symptoms of TMJ dysfunction. The magnitude of the associations between the variables and chewing difficulty, notably tooth loss and the need for a dental prosthesis, emphasize the importance of subjective indicators for assessing the oral health status of adults and shows that chewing difficulty is associated with a range of multi-dimensional factors.

Dental status, oral prosthesis and chewing ability in an adult and elderly population in southern Brazil

OBJECTIVE

The objective of this study was to explore the factors associated with inadequate chewing in an adult and elderly population of a city in the southern region of Brazil.

METHODS

This was a cross-sectional study based on a population home-based inquiry (DCH-POP) in southern Brazil. Individuals were interviewed by trained interviewers to create a standardized procedure. In a pilot study, the Questionnaire of Human Communication Disorders (DCH-POP) was created and validated to identify self-reported speech and language, swallowing and hearing disorders. The outcome was dichotomized into either having adequate chewing or not, as assessed by a series of questions about chewing ability. Analyses of absolute and relative frequencies were measured according to the studied variables. A Poisson regression was applied at a significance level of 5%.

RESULTS

A total of 1,246 people were interviewed. Inadequate chewing was found in 52 (5.6%) individuals, with a higher prevalence in the elderly (11.8%) than in adults (5.2%). In the final model, the following factors were associated with inadequate chewing: being 61 years of age or older (prevalence ratio or PR=9.03; 95% CI: 1.20-67.91), loss of teeth and use of unadjusted prosthesis (PR=3.50; 95% CI: 1.54-7.95), preference for foods of soft consistency (PR=9.34; 95% CI:4.66-8.70) and difficulty in nasal breathing (PR=2.82; 95% CI: 1.31-6.06).

CONCLUSION

Age, oral health status through dental prosthesis, preference for foods of soft consistency and difficulty breathing through the nose were factors associated with chewing inability in adults and the elderly.

Características orofaciais de idosos funcionalmente independentes

RESUMO Objetivo conhecer as características orofaciais de idosos funcionalmente independentes e analisar a associação com a idade, gênero, nível socioeconômico e estado dentário. Método estudo observacional, transversal de caráter analítico com amostra não probabilística. Foi aplicado o instrumento validado “Protocolo de Avaliação Miofuncional Orofacial com Escalas para Idoso” em sujeitos funcionalmente independentes com idade igual ou acima de 60 anos, em boas condições de saúde segundo avaliação geriátrica padronizada, intitulada Protocolo de Avaliação Multidimensional do Idoso. Resultados os idosos apresentaram padrões de normalidade acima de 60% nos parâmetros de aspecto e mobilidade das estruturas. As alterações significantes foram: sulco nasolabial acentuado; bochechas flácidas ou arqueadas; vedamento labial com tensão ou ausência de vedamento e comissuras labiais deprimidas. As alterações de mobilidade foram pequenas, entre 20,6% e 33,8%, com maior prevalência na elevação da língua e lateralização do ar em bochechas infladas e da mandíbula. Não houve relação destes achados perante a progressão da idade e as classes socioeconômicas. As mulheres apresentaram maior chance de exibirem aspecto normal dos lábios e alguma alteração da mobilidade. O número de dentes associou-se com o volume e a configuração dos lábios e a mobilidade da mandíbula. Além disso, o uso de prótese dentária associou-se significativamente com o aspecto do sulco nasolabial e a tensão/configuração das bochechas. Conclusão este trabalho sugere que o sistema oromiofacial encontra-se dentro dos padrões de normalidade na maioria dos idosos funcionalmente independentes. O que ampara a atuação multiprofissional na prevenção, promoção e tratamento da saúde oromiofuncional dos idosos.

[Living and health conditions of elderly people over 80]

OBJECTIVE

This article proposes to describe demographic data and health conditions of elderly people at age 80 or more.

METHOD

Quantitative-descriptive study of 95 elderlies from five units of the Family Health Strategy in the period from September to December 2013, using script with general data of the living conditions and health, including validated scales in geriatrics and gerontology.

RESULTS

The average age was 85.4 years. There was a predominance of women. Most were widowers with family income, more frequently between 2 or 3 minimum wages and economic participation is for means of sharing responsibility. They present dependency for many of Daily Living Instrumental Activities and, on average, reported 2.2 diseases. Fear of falling, decreased vision and hearing as well as pain in different body regions are reported.

CONCLUSION

It appears that they have more intense needs than the elderly in general, requiring new ways of organizing their health care.

HV. Autopercepção da capacidade mastigatória em indivíduos idosos

INTRODUÇÃO: A mastigação desempenha importante papel na preparação do alimento e manutenção da atividade muscular necessária para outras funções do sistema estomatognático. No idoso, esta função pode sofrer mudanças decorrentes de alterações estruturais, morfológicas e bioquímicas. OBJETIVO: Estudar a capacidade mastigatória referida pelos idosos, elencando as dificuldades durante a mastigação. MÉTODOS: Trata-se de estudo observacional do tipo transversal com idosos de 60 anos de idade ou mais, em atendimento ambulatorial em hospital universitário. A coleta de dados foi realizada por meio da aplicação de questionário, contendo questões referentes ao processo de alimentação do idoso e sua capacidade mastigatória. Para fins de comparação entre alguns itens do protocolo e a capacidade mastigatória, esta última variável foi dicotomizada em "satisfatória" e "insatisfatória". Para essas análises, foi utilizado o teste Exato de Fisher, considerando o nível de significância de 5%. RESULTADOS: A amostra foi composta por 30 participantes, com idade média de 74,4 anos (+9,1). Verificou-se elevada perda dentária, o que se refletiu na alta frequência de idosos usuários de próteses. Quanto às dificuldades referidas sobre a mastigação, 46,7% estavam impossibilitados de comer algum alimento, 50% sentiam necessidade de ingerir líquidos durante a refeição, e os alimentos que representaram maiores dificuldades para mastigar foram: carne (53,3%), frutas e verduras cruas (46,7%) e cereais (40%). Quanto à autopercepção da capacidade mastigatória, 53,3% referiram como satisfatória e 46,6% como insatisfatória. Observou-se relação estatisticamente significante entre "autopercepção da capacidade mastigatória" e os alimentos referidos pela dificuldade ao mastigar (p≤0,001). CONCLUSÃO: A capacidade mastigatória autorreferida foi satisfatória em sua maioria e os alimentos sólidos mais duros apresentaram maiores dificuldades na mastigação.

Masticatory changes as a result of oral disorders in smokers

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.

Autopercepção da mastigação e fatores associados em adultos brasileiros

Propôs-se estimar a prevalência da autopercepção da mastigação e investigar os fatores relacionados à autopercepção regular e ruim. Foram entrevistados e examinados 13.431 adultos, participantes do projeto SBBrasil. Foram realizadas análises descritiva, bivariada (χ2; p < 0,20) e multivariada por meio de regressão logística multinomial (p < 0,05), com IC95%. 55,6% classificaram a mastigação como boa; 24,9%, como regular; e 19,5%, como ruim. Na analise bivariada, todos os fatores foram associados à autopercepção da mastigação regular ou ruim (p < 0,20). No modelo final, os fatores associados tanto com a percepção regular como ruim foram: não receber informações sobre como evitar problemas bucais, apresentar menos de 23 dentes remanescentes, necessitar de prótese parcial ou total, perceber a saúde bucal como regular ou ruim/péssima, relatar dor em dentes e gengivas e necessidade de tratamento odontológico. Conclui-se que diversos fatores associam-se à autopercepção da mastigação, principalmente as condições subjetivas, reforçando sua importância como indicador em saúde bucal.
