Non-invasive mechanical ventilation and severity in temporomandibular dysfunction in patients with chronic obstructive pulmonary disease

Abstract

Introdução: A Doença Pulmonar Obstrutiva Crónica é uma das principais causas de morbilidade e mortalidade, sendo a Ventilação Mecânica Não Invasiva (VMNI) um meio de intervenção. Tendo em conta a biomecânica da Articulação esta intervenção pode originar Disfunção Temporomandibular (DTM). Objetivo: Verificar a prevalência de DTM, avaliar a severidade de DTM associada ao número de horas/anos de utilização de VMNI, e a severidade de DTM em função do tipo de interface e modo ventilatório em doentes com patologia obstrutiva. Metodologia: Estudo transversal constituído por 49 doentes com patologia obstrutiva. Foi aplicado o Questionário Anamnésico de Fonseca. Para o tratamento dos dados utilizou-se o coeficiente de Correlação de Spearman e o teste de Mann-Whitney com α=0.05. Resultados: Relativamente à severidade de DTM constatou-se que 15 indivíduos apresentavam DTM leve. Verificou-se uma associação positiva estatisticamente significativa entre o número de horas/anos de VMNI (r=0,422; p=0,01) e uma diferença estatisticamente significativa entre a severidade de DTM e modo ventilatório (p=0,018). Conclusão: A maioria dos doentes apresentava DTM leve, e verificou-se uma associação positiva entre o número de horas e de anos de utilização de VMNI.ABSTRACT: Introduction – Chronic obstructive pulmonary disease is one of the main causes of morbidity and mortality, and non-invasive mechanical ventilation (NIMV) is a means of intervention. Taking into account the biomechanics of the Articulation this intervention can cause temporomandibular dysfunction (TMD). Objective – To verify the prevalence of TMD in individuals with chronic obstructive pulmonary disease. Secondarily, it was intended to assess the severity of TMD associated with the number of hours/years of NIMV use, the type of interface and the ventilatory mode in these patients. Methods – A cross-sectional study consisting of 49 patients with obstructive pathology. The Fonseca Anamnestic Questionnaire was applied. For the data treatment, the Spearman Correlation coefficient and the Mann-Whitney test with α=0.05 were used. Results – Regarding the severity of TMD, it was verified that 15 individuals had light TMD. There was a statistically significant positive association between the number of hours/years of NIV use (r=0.422, p=0.01) and a statistically significant difference between the severity of TMD and ventilatory mode (p=0.018). Regarding the severity of TMD as a function of the type of interface (p=0.833), it was found that there were no statistically significant differences. Conclusion – It was concluded that the majority of patients with chronic obstructive pulmonary disease had TMD and were classified as mild TMD. There was a positive association between the number of hours and years of use of NIV in these patients.info:eu-repo/semantics/publishedVersio
