Abstract

BACKGROUND AND OBJECTIVES: Homeless people are a reality of social vulnerability, poverty and exclusion and are considerably more affected by long-term pain (chronic pain) than the general population. The objective of this study was to evaluate the presence of symptoms of temporomandibular disorder (TMD) in homeless people who attended a reception center for this population (POP Center) in the city of Juazeiro do Norte-CE. 
METHODS: This is an observational, cross-sectional, descriptive-exploratory study, whit a quantitative approach and a convenience sample. For this, the TMD-Pain Screener was applied to measure TMD frequency in 100 individuals who were divided into two groups, group 1 (G1, n=50) composed of residents who were assisted by the center and group 2 (G2, n=50) individuals who worked in the center. The TMD Pain Screener instrument was used and the data were paired according to gender and age group. The Qui-square test was applied to verify associations between the variables, considering a level of significance of 5% (p≤0.05). 
RESULTS: It was observed that homeless people had fewer TMD symptoms than the control group and this difference was statistically significant (p=0,045). The symptom of pain in the lateral region of the head was the most commonly found, being reported by 20% of the homeless population and by 48% of the control group 48% (p=0.03). 
CONCLUSION: The homeless population presented TMD symptoms, which should be taken into account by the health authorities, however, in a smaller proportion than the control group, requiring further studies to identify these differences.

Resumo

JUSTIFICATIVA E OBJETIVOS: As pessoas em situação de rua vivem uma realidade de vulnerabilidade social, pobreza e exclusão e são consideravelmente mais afetadas pela dor de longa duração (dor crônica) do que a população em geral. O objetivo deste estudo foi avaliar a presença de sintomas de disfunção temporomandibular (DTM) em moradores de rua que frequentam o centro especializado de assistência à população de rua (Centro POP) da cidade de Juazeiro do Norte-CE.
MÉTODOS: Este é um estudo observacional do tipo transversal, descritivo-exploratório, com abordagem quantitativa e amostra por conveniência. Para isso, foi aplicado o TMD-Pain Screener para medir a frequência de DTM em 100 indivíduos que foram divididos em dois grupos, grupo 1 (G1, n=50) composto de residentes que foram assistidos pelo centro e grupo 2 (G2, n=50) indivíduos que trabalhavam no mesmo local. O instrumento TMD Pain Screener foi utilizado e os dados foram emparelhados de acordo com o sexo e a faixa etária. O teste Qui-quadrado foi aplicado para verificar associações entre as variáveis, considerando um nível de significância de 5% (p≤0.05). 
RESULTADOS: Foi observado que as pessoas em situação de rua apresentaram menos sintomas de DTM do que o grupo controle (p=0,045). O sintoma de dor na região lateral da cabeça foi o mais relatado, sendo reportado por 20% da população em situação de rua e por 48% dos indivíduos do grupo controle 48% (p=0,03). 
CONCLUSÃO: A população em situação de rua apresenta sintomas de DTM, o que deve ser levado em consideração pelas autoridades sanitárias, contudo, em menor proporção do que a população em geral, sendo necessários mais estudos para a elucidação dessa desproporcionalidade.
