ABSTRACT

ABSTRACT Purpose: to assess the influence of dentures on the electromyographic activity of masticatory muscles in individuals with Parkinson's disease. Methods: an analytical, quantitative, cross-sectional study conducted at a public teaching hospital in 2017, assessing the stage of the disease, non-denture (ND) wearing, upper removable partial denture wearing (DW1), upper and lower removable partial denture wearing (DW2), and upper complete denture + lower removable partial denture wearing (DW3). The Student-Newman-Keuls test was used to compare the maximum voluntary muscle contraction between sides and between the denture wearing and non-denture wearing groups. Significance was set at α<0.05. Results: after applying the eligibility criteria, 41 patient records were included in the sample. The association between the stage of the disease and denture wearing showed predominance of DW2 in stage 1 (43%). A significant difference was found in the masseter muscle analysis between the non-denture wearing group and DW2 and DW3 (p=0.0018). As for the anterior temporalis muscle, there was a significant difference (p=0.0034) in three of the analysis groups (ND vs. DW2, ND vs. DW3, and DW1 vs. DW3). Conclusion: denture wearing has a negative impact on the electrical activity of masticatory muscles when compared with individuals who do not wear dentures and have natural teeth.

ABSTRACT

ABSTRACT Purpose: to assess the bite force in people with Parkinson's disease and correlate it with age, sex, stage and time of the disease, dentures use, presence of temporomandibular disorder, side of symptom onset, and masticatory preference. Methods: the Research Diagnostic Criteria for Temporomandibular Disorders and the Hoehn & Yahr Parkinson's disease scale were used, and the participants' oral cavity was clinically examined. Then, the bite force was measured with an analog dynamometer, whose bar was adapted for mouth grip. The bite force results and their correlation with the variables were analyzed with the independent t-test (p<0.05). Results: the sample comprised 42 parkinsonians at a mean age of 64 years, 67% of whom were males. No difference was observed in the correlation with age, temporomandibular disorder, stage and time of Parkinson's disease; or between the sides, symptom onset and masticatory preference. However, there was a significant association between the sexes (males and females) for both sides (right - p=0.002; left - p=0.04) and denture use for bite force on the right side (p=0.03). Conclusion: being a female and using dentures are factors associated with decreased bite force in people with Parkinson's disease.


RESUMO Objetivo: avaliar a força de mordida em pessoas com doença de Parkinson e correlacionar com: idade, sexo, estágio e tempo da doença, uso de prótese dentária, presença de disfunção temporomandibular, lado de início dos sintomas e preferência mastigatória. Métodos: foi aplicado o questionário Critério de Diagnóstico para Pesquisa em Disfunção Temporomandibular, a escala Hoehn & Yahr para estágio da doença de Parkinson e realizou-se o exame clínico da cavidade oral. Seguido do registro da força de mordida, utilizando um dinamômetro analógico, com haste adaptada para a preensão bucal. Os resultados obtidos da força de mordida e correlação com as variáveis foram analisadas por meio do teste T independente (p<0,05). Resultados: a amostra foi composta por 42 parkinsonianos com média de idade de 64 anos, desses 67% eram do sexo masculino. Observou-se não haver diferença na correlação com: idade, disfunção temporomandibular, estágio e tempo de diagnóstico da doença de Parkinson, bem como entre os lados, início dos sintomas e preferência mastigatória, no entanto, houve associação significante entre os sexos: masculino e feminino para ambos os lados (direito - p=0,002; esquerdo - p=0,04) e na utilização de prótese dentária para a força de mordida do lado direito (p=0,03). Conclusão: constatou-se que ser do sexo feminino e fazer uso de prótese dentária são fatores associados à redução da força de mordida em pessoas com doença de Parkinson.

ABSTRACT

ABSTRACT Purpose: to analyze the predictors of temporomandibular disorder in people with Parkinson's disease, verifying their associations with sociodemographic aspects and stages of the disease. Methods: a study based on secondary data from research conducted in 2017 with 110 people with Parkinson's disease. They were assessed with the Research Diagnostic Criteria for Temporomandibular Disorders and the Parkinson's disease staging scale. The studied predictive variables for temporomandibular disorder were pain, crepitation, clicking, nighttime and daytime clenching/gnashing, uncomfortable/non-habitual bite, morning rigidity, and tinnitus. The sociodemographic aspects assessed were age, sex, schooling level, marital status, income, and stages 1 to 3 of the disease. The chi-squared odds ratio was used with a 95% confidence interval and significance level at p < 0.05. Results: an association was verified between nighttime clenching/gnashing and income (p = 0.006); tinnitus and income range from ½ to 3 (p = 0.003) and from 4 to 10 minimum wages (p = 0.004); and between tinnitus and stage 1 (p = 0.02). Conclusion: this study verified that the predictors associated with temporomandibular disorder in people with Parkinson's disease were pain, clicking, crepitation, uncomfortable/non-habitual bite, and morning rigidity. It was verified that income and stage 1 of the disease had an association with nighttime clenching/gnashing and tinnitus.


RESUMO Objetivo: analisar os preditores de disfunção temporomandibular em pessoas com doença de Parkinson (DP) verificando suas associações com aspectos sociodemográficos e estágios da doença. Métodos: estudo que utilizou fonte de dados secundários de uma pesquisa realizada em 2017, com 110 pessoas com DP que foram avaliadas pelo questionário para Pesquisa em Disfunção Temporomandibular (RDC/TMD) e pela escala de estadiamento da DP. As variáveis preditoras de DTM estudadas foram: dor, crepitação, estalido, apertamento/rangido noturno e diurno, mordida desconfortável/não habitual, rigidez matinal e zumbido. Os aspectos sociodemográficos avaliados foram: idade, sexo, escolaridade, estado civil, renda e estágios da doença de 1 a 3. Utilizou-se o Odds ratio do Qui-quadrado com intervalo de confiança de 95% e nível de significância de p<0,05. Resultados: verificou-se associação entre os preditores: apertamento/rangido noturno e renda (p=0,006); zumbido e grupos de renda ½ a 3 (p=0,003) e de 4 a 10 salários mínimos (p=0,004). Além da associação do zumbido e estágio 1 (p=0,02). Conclusão: nesse estudo verificou-se que os preditores associados com a DTM em pessoas com DP foram: dor, estalido, crepitação, mordida desconfortável/não habitual e rigidez matinal. E destes verificou-se associação entre renda e estágio 1 da doença com apertamento/rangido noturno e zumbido.

ABSTRACT

ABSTRACT BACKGROUND AND OBJECTIVES: Parkinson's disease leads to mandibular movements that affect the masticatory cycle and induce orofacial pain, one of the main clinical alterations found in temporomandibular dysfunction. Thus, the present study aimed to analyze the possible factors associated with temporomandibular dysfunction and to verify the frequency of the dysfunction in this population. METHODS: This was a cross-sectional study in which the participants were evaluated using the Diagnostic Criteria for Temporomandibular Dysfunction research, used to classify the temporomandibular dysfunction and to obtain by physical examination and self-report the variables studied. RESULTS: A total of 139 people with Parkinson's disease were evaluated. Of these, 77 met the eligibility criteria, with 70% of the sample being male, with an average age of 62±9 years; Parkinson's disease diagnosis time of 6±4 years and with 71% of the sample in the moderate stage of Parkinson's disease. No significant associations were found between age, gender, time and stage of the disease with temporomandibular dysfunction. Of the variables analyzed, the significant results showed that the presence of pain (OR=10.92, 95% CI=2.25-59.93, p<0.001) has a greater chance of developing temporomandibular dysfunction, crepitation (Kappa=0.34, p<0.004) reflects moderate accuracy in the classification of temporomandibular joint disorder and the click (negative predictive value=77%, p<0.032) increases the probability of having temporomandibular dysfunction. CONCLUSION: Therefore, in this study, the frequency of the temporomandibular dysfunction was 30%, and it was observed that the factors associated with the dysfunction in people with Parkinson's disease were: pain, click, and crackle.


RESUMO JUSTIFICATIVA E OBJETIVOS: A doença de Parkinson leva a movimentos mandibulares que afetam o ciclo mastigatório e induzem a dor orofacial, uma das principais alterações clínicas encontradas na disfunção temporomandibular. Sendo assim, o presente estudo objetivou analisar os possíveis fatores associados à disfunção temporomandibular e verificar a frequência da disfunção nessa população. MÉTODOS: Trata-se de um estudo de corte transversal, no qual os participantes foram avaliados com o Critério de Diagnóstico para pesquisa em disfunção temporomandibular, utilizado para classificar a disfunção temporomandibular e obter, através do exame físico e autorrelato, as variáveis estudadas. RESULTADOS: Foram avaliadas 139 pessoas com doença de Parkinson. Dessas, 77 encontraram-se dentro dos critérios de elegibilidade, sendo que 70% da amostra era do sexo masculino, com média de idade de 62±9 anos, tempo de diagnóstico da doença de Parkinson de 6±4 anos e com 71% da amostra no estágio moderado. Não foram encontradas associações significativas entre a idade, sexo, tempo e estágio da doença com a disfunção temporomandibular. Das variáveis analisadas, os resultados significativos mostraram que a presença de dor (OR=10,92; IC95%=2,25-59,93; p<0,001) representa uma maior chance de desenvolver a disfunção temporomandibular, a crepitação (Kappa=0,34; p<0,004) reflete uma precisão moderada na classificação do transtorno da articulação temporomandibular e o estalido (valor preditivo negativo=77%; p<0,032) aumenta a probabilidade de ter a disfunção temporomandibular. CONCLUSÃO: Neste estudo, a frequência de disfunção temporomandibular foi de 30% e verificou-se que os fatores associados à disfunção em pessoas com doença de Parkinson foram dor, estalido e crepitação.
